Test Driven Development (TDD) is a software development practice that involves writing a failing test first, then code to pass that test, and refactoring the code. Behavior Driven Development (BDD) builds on TDD and describes how the end user will interact with the software using scenarios and steps. BDD tools like Cucumber use regular expressions to match steps in scenarios to code.
This presentation introduces the key testing concepts of the PHPUnit testing framework. It discusses unit testing, test cases, fixtures, stubs, mocks, and best practices for organizing and running tests. The presentation emphasizes that unit testing isolates and tests the smallest parts of an application to find errors, facilitate refactoring, and enable automated testing. PHPUnit allows writing tests for PHP code and provides features like data providers, exception handling, and code coverage reports.
The document discusses test-driven development (TDD) and behavior-driven development (BDD). It clarifies that TDD is a design activity, not just about testing, and explains the benefits of TDD such as reducing speculative code and improving quality. It then covers BDD concepts like outside-in development, interaction-based testing, and using mock objects. The document provides examples of testing frameworks like RSpec and practices for writing better tests and mocks.
VT.NET 20160411: An Intro to Test Driven Development (TDD)Rob Hale
This document provides an introduction to test-driven development (TDD). It discusses the benefits of unit testing over end-to-end testing, including error localization, execution time, tighter feedback loops, and test coverage. It defines what constitutes a unit test and what does not. Examples of difficult scenarios to unit test are given. The basic TDD cycle of writing a failing test, making the test pass, and refactoring is explained. An exercise demonstrates applying TDD principles. Mock objects and the differences between the Chicago and London schools of TDD are briefly covered. Finally, additional resources on TDD are listed.
Unit testing and test-driven development are practices that makes it easy and efficient to create well-structured and well-working code. However, many software projects didn't create unit tests from the beginning.
In this presentation I will show a test automation strategy that works well for legacy code, and how to implement such a strategy on a project. The strategy focuses on characterization tests and refactoring, and the slides contain a detailed example of how to carry through a major refactoring in many tiny steps
The document discusses testing legacy Rails applications. It provides steps to get testing set up on a legacy Rails app, including creating a test database, running migrations, and getting Rake tasks to run tests. It emphasizes starting with one test at a time, finding and fixing bugs, and refactoring code. Examples are given of writing a model test based on application logs and fixing a failure by updating code. The document stresses treating methods as isolated boxes and only testing one thing at a time to incrementally add tests to a legacy codebase.
This document discusses test-driven development (TDD), behavior-driven development (BDD), and acceptance test-driven development (ATDD). It explains that while they have different names, they all share the same core idea of using examples from business requirements to create automated tests. The document provides examples of how to write tests before having a user interface, and recommends abstracting from the GUI to focus on business logic. It also lists some popular tools that can be used for ATDD, BDD, and TDD.

TDD and Simple Design Workshop - Session 1 - March 2019Paulo Clavijo
The document discusses test-driven development (TDD) and simple design. It introduces TDD and some of its core practices, including test-driven development, simple design, refactoring, and pair programming. It provides an agenda for a workshop that will cover these topics over three sessions, including extreme programming (XP), the four elements of simple design, test doubles, outside-in TDD, and SOLID principles. The workshop aims to communicate best practices for using technical practices to succeed with agile development.
We've all been faced with legacy code and often decided to rewrite, feeling it will be easier. There are many reasons this can be wrong. Adam Culp will talks about the entire journey of refactoring a legacy code base. He will begin with assessment and why, move on to planning how and when, cover execution and testing, give step-by-step examples, and even show how to manage the process effectively. Attendees will gain insight and tips on how to handle their own pile of code and refactor happy.
Test-driven development (TDD) is an agile software development process where test cases are developed before code. The TDD process involves writing a test, watching it fail, writing code to pass the test, and refactoring code as needed. TDD encourages dividing work into small pieces and promotes high-quality code by requiring tests to pass before adding new features. While TDD requires more initial time writing tests, it can reduce debugging time and defects in the long run.
Introduction to Behavior Driven Development Robin O'Brien
This document provides an introduction to Behaviour Driven Development (BDD). It discusses that BDD aims to bridge communication gaps between developers and clients by using examples written in a common language. It also provides a practical example of setting up BDD with JBehave and Java in IntelliJ IDEA, including creating a story file, steps class, and linking class. The document demonstrates how BDD allows describing desired system behaviors in a way that is understandable to both technical and non-technical stakeholders.
4 Nisan 2015 tarihinde Kadir Has Üniversitesi'nde yapılan 9. Yazılım Teknolojileri Seminer etkinliğinde Eralp Erat'ın yaptığı TDD (Test Driven Design) sunumu
This document provides an overview of test-driven development (TDD). It discusses what TDD is, how the TDD process works through iterations of writing tests first then code, and the benefits it provides like increased confidence in changes and documentation of requirements. The document covers TDD basics like the red-green-refactor cycle and challenges in unit testing like dependencies. It emphasizes focusing on writing tests before code and not designing code in your head first. The document also compares mocking frameworks and argues the benefits of commercial frameworks like Typemock Isolator.
Acceptance Test Driven Development With Spec Flow And FriendsChristopher Bartling
The document discusses Acceptance Test Driven Development (ATDD) using SpecFlow and other tools. SpecFlow is a .NET framework that allows writing acceptance tests in a business-readable language and generates automated tests. Features describe system functionality through scenarios, and SpecFlow generates tests from scenarios. The document also discusses related tools like WatiN and WebAii for browser automation, best practices, and includes a demo of an ATDD-developed Net Present Value calculator.
This document discusses test-driven development (TDD) and behavior-driven development (BDD). It defines TDD as a process of writing automated tests before code to define desired functionality, then writing minimum code to pass tests and refactoring. BDD combines TDD techniques with domain-driven design and focuses on user stories over functions to promote communication. The document provides an example of using BDD to generate scenarios for a life insurance risk example, and shows how TestBox can be used to write automated tests based on those scenarios.
This document discusses Test Driven Development (TDD). It defines TDD, outlines the TDD process which involves writing tests first and then code to pass the tests, and emphasizes refactoring. Benefits of TDD include improved code quality, reduced bugs, and serving as documentation. Key TDD terms and libraries like JUnit and Mockito are explained. Continuous Integration (CI) is also discussed as it automates testing and builds when code is committed.
Pitfalls Of Tdd Adoption by Bartosz BankowskiAgileee
This document discusses test-driven development (TDD) and provides best practices for writing tests using a TDD approach. It begins with an introduction to TDD and why organizations adopt it. It then discusses the author's experience teaching and implementing TDD. The main body provides guidance on what to test, how to structure tests, and pitfalls to avoid, such as bloated fixtures, noisy fixtures, unstable test data, and verifying multiple behaviors in one test. It concludes by emphasizing the importance of training, code reviews, and references additional resources to learn more about TDD.
Writing useful automated tests for the single page applications you buildAndrei Sebastian Cîmpean
How to approach testing if you are building a modern single page application. I try to emphasize that integration testing is the way to go and that developers should consider the tests as part of the system and spend time to maintain them.
The document discusses Behavior Driven Development (BDT) using Microsoft Visual Studio 2010 and SpecFlow, including an overview of BDT, different BDT methodologies, using Gherkin syntax to write scenarios, configuring SpecFlow tests in Visual Studio, and a live demo of SpecFlow.
This document provides an overview of test-driven development (TDD). It defines TDD as a technique for building software where tests are written before code to guide development. The key aspects of TDD covered are:
- Writing tests first before code, which helps improve design and ensures tests are written.
- The TDD mantra of Red-Green-Refactor, where tests initially fail (Red), code is written to pass tests (Green), then code is refactored to improve design.
- An example case study of a large Java project developed using TDD that has over 20,000 lines of unit tests providing over 90% test coverage.
Most projects in CF now involve creating some type of consumable CFC Endpoint or API Service... do you Unit test your API, do you use Integration Tests on your API? How many ways do you test your API? Not all tests are created equal.
Description
Most projects in CF now involve creating some type of consumable CFC Endpoint or API Service... do you Unit test your API, do you use Integration Tests on your API? How many ways do you test your API? Not all tests are created equal.
We build our CFCs and CF API to be consumed with CF Apps, Mobile Apps, Javascript apps and devices we haven’t even thought about yet. To be smart developers we need to be able to test our CFC endpoints, and the code that uses those endpoints.
We’ll learn how to test your API serverside with Testbox and Clientside with Jasmine.
With Testbox and Jasmine both using BDD, your test code can almost be isomorphic.
Attendees should have some exposure to CFCs as endpoints, or CF API creations, and consuming with other languages/devices, in this case, JavaScript.
## Attendees will learn
How to use Testbox to test your CFCs 2 different ways
Different types and ways to test JavaScript
Overview of client/server side testing tools
Building testing into your workflow
You are one of many that are not testing your APIs thoroughly
Obstacle Driven Development is the latest engineering process and combines Test Driven Development with safety critical V-model development.
This updated presentation demonstrates how ODD extends and combines ISO compatible V-model development with Test Driven Development.
Please see the series for further details.
Behaviour-driven development (BDD) started as an improved variation on test-driven development, but has evolved to become a formidable tool that helps teams communicate more effectively about requirements, using conversation and concrete examples to discover what features really matter to the business. BDD helps teams focus not only on building features that work, but on ensuring that the features they deliver are the ones that the client actually needs.
In this talk, we will discuss what BDD is about, its benefits, and how it affects teams and processes. We will discuss two case studies where BDD practices have been successfully introduced, including the benefits gained and challenges met. We will see how much benefit was gained when BDD was integrated into the broader development infrastructure, including issue tracking systems, requirements management, and project reporting.
We will also see how BDD can be applied to all levels of the development process, from requirements down to low-level coding. We will also look at the principle BDD tools available that can help teams implement executable specifications, BDD-style test automation, and living documentation effectively. Some of the tools discussed will include JBehave, Cucumber, Specflow, Jasmine and Spock.
We will also look at two case studies where BDD practices have been successfully integrated into several projects in large government and financial organizations. Teams that adopted BDD effectively benefited from significantly lower defect rates, much earlier discovery of errors and inconsistencies in the requirements, and better overall communication and collaboration within the team. However, practicing BDD does involve a significant change in mind-set compared to more traditional approaches, a different collaboration model between team members, and a high degree of stakeholder by-in and engagement, all of which should not be underestimated. We will discuss how the teams managed these various challenges during their BDD adoption story.

The document discusses using behavior driven development (BDD) to write better test scenarios. It provides an example of a scenario that tests whether a Confluence server is accessible. The author questions whether this scenario truly qualifies as BDD or is instead just a technical test. The discussion covers differences between BDD and technical testing, as well as considerations around using Cucumber for technical tests versus unit tests. The author emphasizes being pragmatic and ensuring scenarios will be read and understood by their intended audience.

Learn what BDD is, and what it is not
Understand that the core of BDD is around conversation and requirements discovery, not around tools.
Understand the difference and similarities between BDD at the requirements level, and BDD at the coding level.
Learn what BDD tools exist for different platforms, and when to use them
This document discusses misunderstandings around behavior-driven development (BDD). It begins by addressing common complaints like clients not wanting to write specifications or feeling testing is unnecessary. The document advocates an approach called "3 amigos" involving developers, business analysts, and a tester to collaboratively explore examples. Finally, it explains that BDD is a full-stack methodology where examples, requirements, and tests inform each other to enhance delivery of business value.
This document summarizes the benefits and mechanics of pair programming. It discusses that all production software should be developed by two programmers working jointly, switching pairs frequently. The benefits include continual code review, improved design quality, fewer defects, more rapid solutions, improved communication among team members, and reduced risk. Potential issues that can arise include difficulties with introverts, experts paired with novices, and individuals who refuse to pair program.
BDD, Gherkin, Cucumber and why we need it.AlexOsadchyy
The document discusses Behavior-Driven Development (BDD) and the use of Gherkin and Cucumber to define acceptance criteria and system requirements through concrete examples. It provides sample requirements and examples written in Gherkin describing the behavior of adding and removing books from a shopping cart. Automating the Gherkin examples allows for the examples to serve as living documentation and automated regression tests.
La Programación Extrema (XP) es una metodología ágil de desarrollo de software que se enfoca en la comunicación, entregas frecuentes, y adaptación continua. XP promueve interacciones frecuentes entre el cliente y el equipo, desarrollo en parejas, pruebas automatizadas, y entregas incrementales basadas en historias de usuario priorizadas por el cliente.

The document discusses behavior driven development (BDD) and test-driven development (TDD). It shows an example of incrementally developing a FizzBuzz program using TDD and JUnit tests. First, a single test is written to verify the output for the number 1. Then tests are added and code is modified to pass each new test, building up the full FizzBuzz logic over multiple test/code iterations. The document also discusses differences between traditional TDD testing and BDD-style testing, where test method names are written as sentences describing expected behavior.

Behaviour-Driven Development (BDD) is a game changer for the whole team! Behaviour Driven Development is a powerful collaboration technique that can empower teams to deliver higher value features to the business faster and more effectively. More than just a testing technique, BDD is both a collaboration and a verification tool, and a vital step on the road to Continuous Delivery.
It is the team who does all the work. Team is self-organising. Team decides and plans. So what is the role of scrum master? Is it a full time role? How is it different from a project manager? Can a project lead or manager be a scrum master? It is probably the least understood and the most abused role in scrum. Let's explore these points in details further on April 10, 3:00 PM.

This document discusses DevOps, including what it is, its principles, challenges and benefits. DevOps aims to bridge the gap between development and operations through communication, collaboration and automation. It allows for rapid product evolution, improved quality and reduced costs and risks. DevOps principles include developing in similar environments to production and frequent, validated deployments. Challenges include release management and coordination, which DevOps addresses through continuous integration, delivery and automation tools. When to adopt DevOps includes ecommerce and websites, but not critical platforms like banking systems.
This document summarizes a talk on getting comfortable with behavior driven development (BDD). It begins by defining BDD and explaining that it builds on test driven development (TDD) by describing application behavior from an outside-in perspective with customer involvement. It then discusses that TDD focuses on writing tests first before code, using a red-green-refactor workflow. BDD further crystallizes requirements and ensures programmer priorities are aligned by implementing tests in business language rather than code. The document emphasizes thinking through requirements before writing code or tests to ensure the correct behavior is described and tested.
Business Value of Agile Testing: Using TDD, CI, CD, & DevOpsDavid Rico
Presentation on the "Business Value of Agile Testing: Using Test Driven Development, Continuous Integration, Continuous Delivery, & DevOps," which are highly-disciplined contemporary new product development (NPD) approaches for rapidly building high-quality information technology-intensive systems. Identifies the motivation for agile methods, provide a brief introduction to agile methods, describe the fundamental mechanics of agile methods, and a brief survey of the benefits of agile methods as reported by major industry studies (including rarely seen, late-breaking economic data and results from the top consulting firms). Defines agile testing and introduce basic and advanced agile testing practices, strategies, metrics, outcomes, costs & benefits, cost of quality, and statistical performance data. Introduces basic and advanced agile scaling practices, case studies of enterprise-level agile testing, Continuous Delivery, and DevOps at major Internet firms, and common agile testing tools and automation suites. Closes with a summary of agile testing adoption rates, common barriers to agile testing, organizational change models for agile testing, and a summary of the benefits of agile testing.
The document outlines the responsibilities of a Scrum Master which include removing blocks for the team, acting as an unbreakable buffer, championing Agile practices, being the chief connector to solve issues, providing frequent feedback, and building individual ownership without acting as a team leader. It notes that the Scrum Master role can vary in visibility from almost invisible on small dedicated teams to highly visible and busy on larger teams with more challenges.
Business Value of CI, CD, & DevOpsSec: Scaling to Billion User Systems Using ...David Rico
This is a presentation on the "Business Value of Continuous Integration, Continuous Delivery, & DevOps(Sec): Scaling Up to Billion User Global Systems of Systems Using End-to-End Automation & Containerized Docker Ubuntu Cloud Image-Based Microservices," which are late-breaking 21st century approaches for rapidly and cost-effectively building high-quality global information systems, minimum viable products, minimum marketable features, service oriented architectures, web services, and microservices using containerization and end-to-end automation.
The document provides guidelines for testing Rails applications. It recommends that any code change should be driven by a failed test. Tests should be close to the code being tested and focus on functionality rather than specific code. It discusses testing models, associations, named scopes, validations, controllers, views, helpers, emails, user interactions, Ajax requests, external sites, Rake tasks, file uploads, legacy applications, and more. The goal is to have tests that result in high-quality code through a test-first approach.
The document provides an overview of unit testing concepts and best practices. It discusses what unit testing is, why it's useful, and common terminology like test-driven development, stubs, spies, mocks and fixtures. It also covers unit testing tools and libraries, specifics of unit testing JavaScript code, and best practices like writing tests that are fast, isolated, consistent and self-descriptive.
Intro To JavaScript Unit Testing - Ran MizrahiRan Mizrahi
The document introduces JavaScript testing and test-driven development (TDD). It discusses why software projects fail, challenges of testing JavaScript code, and how to use the Mocha and ChaiJS frameworks for TDD and behavior-driven development (BDD). It provides an example of writing unit tests for a user service function using TDD principles, implementing the code to pass the tests, and running the tests with Mocha. Benefits of testing code include short feedback cycles, high test coverage, documentation of specifications, and less time spent debugging.
Unit testing with RSpec is a tool for testing Ruby code using a behavior-driven development approach. RSpec allows writing unit tests to test models, controllers, helpers and other code. Writing unit tests brings advantages like confidence in deploying code, documenting how code works, and catching errors. RSpec provides features for testing including describing test contexts and expectations, factories for test data, mocking and stubbing, and spying on method calls.

This document discusses front-end unit testing using the Jasmine testing framework. It explains why unit testing is important, introduces behavior-driven development and the Jasmine framework. It also provides an overview of setting up Jasmine, creating test suites and specs, using matchers, and testing asynchronous code. The document demonstrates how to set up the testing environment, write tests with Jasmine, and integrate Jasmine with the Karma test runner.
This document discusses unit testing JavaScript code using the Jasmine testing framework. It provides an overview of unit testing, behavior driven development (BDD) and how Jasmine supports BDD style testing. It demonstrates how to set up Jasmine, create test suites and specs, use matchers for expectations, and work with spies and async code. The document also discusses how to integrate Jasmine with Karma, a test runner that allows executing tests across multiple browsers.
The document discusses what tests are in Rails and how to write them. It explains that tests should validate functionality, set up data using factories, perform an action, and make an assertion. Tests can be written for models, controllers, and views using RSpec. When tests run, any fixture data is reset, "let" blocks are run for setup, the test method is executed, and teardown blocks are run. Tests can be run using the 'guard' or 'rspec' commands.
Quick Tour to Front-End Unit Testing Using JasmineGil Fink
This document provides an overview of unit testing JavaScript code using the Jasmine testing framework. It discusses why unit testing is important, how to set up Jasmine and Karma for testing, and how to write different types of tests in Jasmine including suites, specs, expectations, matchers, spies, and async support. The document includes code examples and recommends unit testing JavaScript code to increase confidence and catch bugs early in the development process.
The document discusses unit testing in Grails using the Spock testing framework. It covers the basics of unit testing including goals, advantages, and challenges. It then provides an overview of Spock and examples of writing unit tests in Spock including mocking methods, domains, configurations, and dependencies. The document also discusses how to write unit tests for controllers and integration tests in Grails using Spock.

2011-02-03 LA RubyConf Rails3 TDD WorkshopWolfram Arnold
This document provides an overview of test-driven development (TDD) using Rails 3. It discusses why TDD is important, how to structure tests in different layers (model, controller, etc.), and what to test for models, controllers and views. It also covers RSpec 2 and useful tools like RVM. The presentation includes live coding demos and in-class exercises on TDD.
We Are All Testers Now: The Testing Pyramid and Front-End DevelopmentAll Things Open
The document provides an overview of test-driven development (TDD) principles and how to implement testing for front-end development. It discusses the benefits of TDD, such as avoiding bad designs and preventing regressions. It also addresses common challenges with TDD, like slowing initial velocity and ignored tests over time. The document then covers different levels of testing, including unit tests, integration tests, and functional/end-to-end tests using the testing pyramid as a framework. It provides examples of writing tests for pure and impure functions using the Jest testing framework. Finally, it discusses functional testing using Cucumber.js behavior-driven development.
Testing in Rails allows developers to write automated test suites using frameworks like Minitest and RSpec. These frameworks interact with the codebase to run tests from the command line and check that code works as expected. Tests can verify functionality when code is initially written and also help prevent breaks when code is refactored. Test-driven development involves writing tests before code so that tests guide code implementation.
Typescript fundamentals document summarized in 3 sentences:
The document discusses Typescript fundamentals including types, classes, interfaces, modules and how to use the Typescript compiler. It explains how Typescript adds type safety and compile time checking to JavaScript by using types for variables, parameters, returns and more. Examples are provided for many Typescript features and how they compile down to equivalent JavaScript.

Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

4. Test Driven Development
When I first heard about TDD, the idea seemed to be pretty simple. Just by doing a little word swizzling, obviously TDD
is when you have tests that drive your software development.
If we were to unpack the definition of TDD a bit more, we'd see that it is usually broken up into five different stages:
1. First the developer writes some tests.
2. The developer then runs those tests and (obviously) they fail because none of those features are actually
implemented.
3. Next the developer actually implements those tests in code.
4. If the developer writes his code well, then the in next stage he will see his tests pass.
7. BDD
BDD is meant to eliminate issues that TDD might cause.
In contrast to TDD, BDD is when we write behavior &
specification that then drives our software development.
Behavior & specification might seem awfully similar to
tests but the difference is very subtle and important.
8. Example
#Testing for our User class
describe User do
context 'with admin privileges' do
before :each do
@admin = Admin.get(1)
end
it 'should exist' do
expect(@admin).not_to be_nil
end
it 'should have a name' do
expect(@admin.name).not_to be_falsy
end
end
#...
10. var assert = require('assert'),
factorial = require('../index');suite('Test', function (){
setup(function (){
// Create any objects that we might need
});
suite('#factorial()', function (){
test('equals 1 for sets of zero length', function (){
assert.equal(1, factorial(0));
});
test('equals 1 for sets of length one', function (){
assert.equal(1, factorial(1));
});
test('equals 2 for sets of length two', function (){
assert.equal(2, factorial(2));
});
test('equals 6 for sets of length three', function (){
assert.equal(6, factorial(3));
});
});});
11. var assert = require('assert'),
factorial = require('../index');describe('Test', function (){
before(function(){
// Stuff to do before the tests, like imports, what not
});
describe('#factorial()', function (){
it('should return 1 when given 0', function (){
factorial(0).should.equal(1);
});
it('should return 1 when given 1', function (){
factorial(1).should.equal(1);
});
it('should return 2 when given 2', function (){
factorial(2).should.equal(2);
});
it('should return 6 when given 3', function (){
factorial(3).should.equal(6);
});
});
12. If you have seen the previous example then
you can find it out that the first example
for the TDD because inside the developer
only checking the value of the method
But if you have observed the second code
then you will find test are more focus on
the behaviour.
15. 1) By simply running your rails test you can ensure your
code adheres to the desired functionality even after some
major code refactoring.
2) Your application response without having to test it
through your browser
3) You can easily upgrade your rails application
16. Levels of Testing
● Unit Tests
● Integration Tests
● Acceptance Tests
22. Unit Test???
$ rails new TestingTime
$rails generate scaffold profile
title:string body:text
$ rake test test/models/profile_test.rb
23. require 'test_helper'
class ProfileTest < ActiveSupport::TestCase
test "the truth" do
assert true
end
test "should not have Profile with title" do
profile = Profile.new
assert_not profile.save # save the title
without title
end
test "should not have profile without body" do
profile = Profile.new
profile.title = 'Arvind'
assert_not profile.save # save the body without
title
end
end
class Profile < ActiveRecord::Base
class Post < ActiveRecord::Base
validates :title, :body, presence: true
validates :title, :body, presence: true
end
end
$ rake test test/models/post_test.rb
24. Controllers ??
Testing the various actions of a single
controller is called writing functional tests
for that controller.
Controllers handle the incoming web
requests to your application and eventually
respond with a rendered view.
25. require 'test_helper'
class ProfilerofileControllerTest < ActionController::TestCase
setup do
@rofileprofile = rofilesprofile(:one)
end
test "should get index" do
get :index
assert_response :success
assert_not_nil assigns(:profile)
end
test "should get new" do
get :new
assert_response :success
end
test "should create rofileprofile" do
assert_difference('Profilerofile.count') do
post :create, profile: {title: @profrofile.title, body: @profile.body}
end
assert_redirected_to profile_path(assigns(:profile))
assert_equal 'Profile was successfully created.', flash[:notice]
end
26. #run all the test case which are inside test
$ rake test test
i
27. What to include in your
functional test
->Web request successful
-> User redirect to the right place
-> User successfully authenticated
-> Correct object stored in the response
template
- > Appropriate message displayed
28. A Last question for all
What is the use of integration folder in
testing what we put on that ?? ????
