Introduction to Unit Testing using QUnit
Unit testing verifies specific sections of code by testing individual functions to ensure they work as expected. Qunit is a JavaScript unit testing framework that allows testing code in the browser. It provides assertions like ok(), equal(), and deepEqual() to compare actual and expected results. Unit tests are essential for quality assurance and meeting requirements by confirming code works as intended.
Software Testing - Day Two
This document discusses black box and white box testing approaches. Black box testing is done by users based on requirements and functionality, while white box testing is done by developers based on internal code structure. Both testing types are needed to fully validate software. Black box tests the system from the outside based on specifications, while white box tests internally based on implementation. To produce high quality software, both testing approaches should be used along with user involvement and rapid prototyping.
TDD and Unit Testing in Golang
Test-driven development (TDD) is a process where test cases are created to validate requirements before functional code is written. The primary goals of TDD are to help specify requirements and design and to produce clean, bug-free code through a short development cycle of writing tests then code to pass those tests. Good unit tests for TDD should run fast, isolate dependencies, clearly define their scope, not require special setup, and clearly indicate their intention. In Golang, the testing package and go test command provide tools for writing and running tests, and go test can measure test coverage.
Android Test Driven Development & Android Unit Testing
This document discusses test driven development (TDD) using JUnit and Mockito for Android. It defines TDD, explains the benefits which include automated testing and improved code quality. It provides examples of using JUnit for unit testing like parametric testing and test lifecycles. It also explains how to use Mockito to mock dependencies and verify interactions through stubbing and spying. The document emphasizes that TDD leads to more modular, flexible and maintainable code.
Introduction to qa
This document provides definitions for common terms related to quality assurance (QA) and software testing. It defines types of testing like acceptance testing, alpha testing, beta testing, compatibility testing, and more. It also defines concepts like test cases, test coverage, test plans, approaches to testing like black box and white box testing, and aliases for some testing terms.
CRA Integration with Bitbucket
The document discusses implementing automated code review using Checkstyle and PMD across all services. It outlines goals of starting code review actively and increasing awareness of the process. The agenda includes explaining the current approach, discussing code review with developers, and setting caps for the number of allowed issues per class when merging pull requests. It also involves setting a timeline for other services to adopt code review standards and addressing any issues with the current standards file.
Automated testing - how?
Once you understand why you want to practice test automation, there is only one question left - how to do that?
Unit tests, Component tests, End-to-End tests, Continuous integration, Code review, Tools...
Presentation Test Driven Development
This document discusses test-driven development (TDD). It defines TDD as an evolutionary approach where tests are written before code to verify functionality. The TDD cycle involves writing a test, making it pass by writing code, and refactoring code and tests. Advantages include more consistent testing, clarified interfaces and behavior, and confidence to refactor. An example walks through writing tests for password requirements, developing code to pass tests, and refactoring code and tests.

Unit vs. Integration Tests
The slides of my session "Unit vs. Integration Tests" I gave at our Softwerkskammer Meetup Munich.
Abstract:
Unit and integration test fan boys have been fighting against each other since the early days of TDD. Nevertheless in the last years the test pyramid has become the common sense strategy for automated tests synthesizing both approaches in an economic ratio. Unfortunately in practice the vague and abstract concept leaves us alone with a lot of remaining questions.
I will start the session introducing the test pyramid strategy and the strengths and weaknesses of the different kinds of tests followed by implementation approaches valuable for real life. Then we will split up into small groups and discuss there what in our current projects works well for us and work together on how we can approach remaining challenges. In the end we will come together again and exchange our solutions in the full audience.
API Automation Testing Using RestAssured+Cucumber
The slides cover the introduction to cucumber, testNG, RestAssured why is BDD used, Basic concepts, and terminologies used in RestAssured, cucumber and TestNG.
Automated Testing DITA Content and Customizations
The document discusses various methods for automated testing of DITA content and output, including using Schematron for validating content structure, the QA plugin for identifying tagging errors, XMLUnit for comparing XML, and the DITA OT regression test for validating the output of the open-source DITA Open Toolkit. It also covers automating browser tests using Selenium and comparing HTML output using Needle and Nose. Demo examples are provided for several of these automated testing tools and techniques.

It describes what NUnit is, how to install and use it, key concepts like test fixtures and methods, and provides an example of writing unit tests for a calculator class using NUnit's attributes. The document also covers running tests via the NUnit GUI or console, and examining the output XML file for test results.
Keeping code clean
One of the main hindrances to teams being able to respond rapidly to new features are technical problems resulting from bad coding practices, also known as technical debt. Melissa and Brett will cover Agile tools and practices that help development teams write better code and increase maintainability. Topics that will be covered include:
Pair programming
Automated Unit Testing
Refactoring
Test-Driven Development
Agile Architecture
Testing the untestable
1. The document discusses techniques for testing legacy production code that was not originally written with testability in mind. This includes unit testing, which allows verifying code works as expected in isolation, and writing tests before making changes to help preserve existing behavior.
2. Testing legacy code can be challenging as the code may have dependencies that are hard to isolate for testing purposes. Techniques to address this include extracting functions to new classes, replacing static dependencies with interfaces, and overriding classes to inject test dependencies.
3. While testing legacy code requires more initial work, it provides long-term benefits like reducing defects, empowering refactoring, and creating a safety net for future changes. The document provides a case study and
Presentacion testing-procesos
This document outlines different types of testing applied to business applications including:
1. Static testing involves reviewing documentation and requirements. Dynamic testing validates requirements and includes usability, system integration, and regression testing.
2. Integration testing is done by developers, testers, and QA analysts and includes unit testing tools. Completed test formats are loaded for integration and system testing.
3. Confirmation, usability, and regression testing are performed by QA analysts. Usability testing checks functionality, visual design, and browser compatibility. Regression testing validates that modifications haven't introduced defects.
4. User acceptance testing involves clients accessing applications and APIs to test functionality and provide test results via email.
Data Generation with PROSPECT: a Probability Specification Tool
The document describes PROSPECT, a tool for automatically generating synthetic data from probabilistic specifications. PROSPECT allows users to specify discrete temporal distributions declaratively and solves the specifications algebraically to obtain unique parameter solutions. If a unique distribution is defined, PROSPECT can sample from it. The document outlines PROSPECT's specification language and approach, which involves parameterizing specifications, solving systems of equations, and sampling solutions. An evaluation found PROSPECT specifications were more succinct than probabilistic programs and generated accurate data.
Design by contract
Design by Contract (DBC) is a software development technique that uses assertions to specify obligations between software components. Preconditions specify what a client must provide before a method executes. Postconditions specify guarantees a component makes after method execution. Invariants specify conditions that must always hold for a class. DBC helps ensure high-quality software by validating contracts at runtime. Java supports DBC through assertions and third-party libraries allow its use through annotations and AspectJ.
Back to basics - PHPUnit
Unit testing involves testing individual units of code to ensure they function as intended. Unit tests isolate and test each part of a program to show they are correct. Benefits of unit testing include finding problems early, facilitating change, simplifying integration, and serving as living documentation. PHPUnit is a popular unit testing framework for PHP, which can be installed via PEAR. Tests are written to make assertions and test exceptions, data, and dependencies. Results can be logged in verbose mode or testdox format.

Key advantages are finding problems early, demonstrating code works, and ensuring regressions don't reoccur. The document covers the XCTest framework, writing testable code, mocks and stubs. It provides examples of writing unit tests in Xcode including for asynchronous operations and performance. Continuous integration with Xcode Server is also discussed.
Software testing assignment
Software testing is a process used to evaluate the quality of a product or service by measuring for completeness, correctness, and security. It involves technical investigations to understand risks. Verification checks work products against requirements, only using static testing techniques. Validation evaluates the final product to ensure it meets business needs, using dynamic testing like smoke and regression testing. There are many types of testing including unit, integration, functional, system, stress, performance, usability, acceptance, regression, and beta testing, which can be white box or black box and test at the unit, integration, system, and acceptance levels.
TDD - Designing with Expectations, not Implementations
TDD approach made simple based on the experience and journey gone through learning and implementing it in a large scale android app, i.e. Shaadi.com.
Unit testing
The document outlines five phases of software testing: development, system and integration, user acceptance, implementation, and regression testing. It describes unit testing as focusing on testing individual code units for functionality and reliability. Unit tests are conducted during the development phase using structural or functional techniques. Entry criteria for unit testing include having 80% complete and approved business requirements, a finalized technical design, and an established development environment. Exit criteria include holding a testing transition meeting where developers sign off and receiving project manager approval.

The document discusses static analysis tools for finding bugs in source code. It summarizes the Coverity Scan service, which allows open source projects to have their code scanned for defects free of charge. The document outlines how to integrate Coverity Scan into a project's workflow, including using the cov-build wrapper to package code for analysis and submitting builds through services like Travis CI. It also provides tips for fine-tuning scans and examples of how the Linux and EFL projects use Coverity Scan in their development.
Quality Software With Unit Test
The document discusses different types of software testing including unit testing, integration testing, functional testing, and regression testing. It emphasizes that writing automated tests is important to ensure code quality and that tools like JUnit can be used to automate testing. It also discusses concepts like code coverage, assertion density, indirect testing, and testedness which aim to more precisely measure the effectiveness of tests.
Automation testing
This document discusses automation testing. It begins by defining automation testing and listing its benefits, which include saving time and money, improving accuracy, and increasing test coverage. It then covers levels of automation testing, frameworks, approaches like record and playback, modular scripting, and keyword-driven testing. The document also discusses the automation testing lifecycle, how to choose a testing tool, types of tools, when to automate and who should automate, supporting practices, and skills needed for automation testing.

Modern Testing Strategies for Evolving Ecosystems
Review of current approaches to testing software.
Goal is to promote understanding of the need for designing blended approaches, where different techniques are used for different purposes.
To share the idea that each software ecosystem has unique set of concerns that can only be addressed effectively by mixing up some of the presented techniques in balanced proportions.
To understand, at times when highly heterogeneous distributed software architectures become commodity, it is important to re-define concepts such as quality, correctness and robustness to prevent loosing predictability of system behavior.
TDD - Agile
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.
Client Side Unit Testing
The document discusses client-side unit testing. It begins by noting common reasons developers give for not writing tests, such as believing tests are unnecessary or that code is too complex. It then explains the goals of introducing functional testing before unit testing, including automating manual testing and proving functionality from a user perspective without considering internal structure. The document contrasts functional and unit testing, noting unit testing focuses on complete isolation of individual units while functional testing covers most user cases. It argues that as programmers, writers should implement unit tests to ensure high quality code. The remainder covers best practices for unit testing including using a BDD framework, test organization into suites/specs/expectations, and examples of succinct testing syntax.

Unit Tests And Automated Testing
The document discusses unit testing and automated testing. It defines various testing terminology like unit tests, integration tests, system tests, and regression tests. It emphasizes the importance of testing early and often to find bugs quickly, increase quality assurance, and improve code design for testability. Automating tests through continuous integration is recommended to efficiently run tests on new code commits and catch errors early. Test-driven development is introduced as a practice of writing tests before code to ensure all tests initially fail and the code is developed to pass the tests.
Cleaner Code Through Test-Driven Development
Test-driven development (TDD) involves writing unit tests before production code to ensure features are correctly implemented and prevent future bugs. Following TDD best practices like writing only enough test code to fail and then just enough production code to pass helps improve code quality and productivity. Leading open source projects emphasize the importance of testing, with some requiring over 90% test coverage. Resources like books and articles provide guidance on techniques like TDD, refactoring, and working with legacy code.
Enter the mind of an Agile Developer
This document discusses BSG's approach to agile software development. It covers their use of agile methodologies like Scrum, test-driven development, behavior-driven development, and pair programming. It also describes their testing strategy, which uses a hybrid of BDD and TDD with a domain specific language. Tests are written at multiple levels, from acceptance to unit, and are run locally and through continuous integration with Jenkins.
Android TDD

* Android Testing Framework
* JUnit 4 + POJO Library
* Robolectric
Unit testing
This document discusses unit testing and provides an overview of its benefits and best practices. It defines unit testing as testing small pieces of code in isolation. It recommends writing unit tests for all code to check functionality and prevent bugs, and integrating testing into the development process by writing tests before code and ensuring tests pass before check-ins. The document also discusses test-driven development, refactoring code based on test results, and tools like NUnit that can automate the testing process.
Testing & continuous delivery
This document discusses software development best practices including unit testing, integration testing, continuous integration, and continuous delivery. Unit testing isolates and tests individual code units to verify they work as intended. Benefits include finding problems early and allowing refactoring without fear of regressions. Limitations are that tests only check for certain errors and require additional test code. Common unit testing tools include JUnit and Mock objects which simulate objects for testing. Integration testing combines modules tested individually. Continuous integration runs automated tests and builds on every code change. Continuous delivery fully automates the software delivery process.

It explains that testing ensures code quality, reduces bugs, and improves reliability. Unit testing focuses on individual code components in isolation while integration testing checks interactions between components. Functional testing evaluates application functionality from a user perspective and acceptance testing validates requirements. Performance testing evaluates speed, responsiveness, and scalability under load. The document recommends test-driven development, test automation, isolation, coverage, and continuous integration as best practices.
Regression Testing with Symfony
For web applications you often need the ability to deploy new features continuously while making sure that all parts of your application still work correctly. Establishing an Continuous Integration process using an automated test suite can support you to meet those needs. This presentation tries to give an overview how this integration process can be established for Symfony2 applications and which types of tests apply.
The presentation was held on the Symfony User Group Berlin on 10 Okt. 2012
Getting Started with Test-Driven Development at Longhorn PHP 2023
Test-driven development (TDD) is a software development process where test cases are written before code to validate requirements. The TDD process involves short cycles of adding a test, making the test fail, writing code to pass the test, and refactoring code. Automated tests provide confidence to refactor and change code without breaking functionality. Unit tests isolate and test individual code units while feature tests simulate how a user interacts with the application. Code coverage metrics help ensure tests cover enough of the codebase, with higher coverage percentages generally indicating better test quality.
Test driven development(tdd)
Test Driven Development (TDD) is a software testing methodology where developers write automated test cases before writing any code. It involves writing a failing test case for new functionality, then writing the minimum amount of code to pass that test, and refactoring the code. Key steps are to add a test, run all tests and see the new one fail, write code to pass the test, run tests to succeed, and refactor code while maintaining tests. Benefits include instant feedback, better code quality, and lower rework effort. Limitations include difficulty testing certain types of code like GUIs. Unit testing tests individual units of code in isolation through mocking of external dependencies.

Measures in SQL (SIGMOD 2024, Santiago, Chile)
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.

Closing talk for the Performance Engineering track at Community Over Code EU (Bratislava, Slovakia, June 5 2024) https://eu.communityovercode.org/sessions/2024/why-apache-kafka-clusters-are-like-galaxies-and-other-cosmic-kafka-quandaries-explored/ Instaclustr (now part of NetApp) manages 100s of Apache Kafka clusters of many different sizes, for a variety of use cases and customers. For the last 7 years I’ve been focused outwardly on exploring Kafka application development challenges, but recently I decided to look inward and see what I could discover about the performance, scalability and resource characteristics of the Kafka clusters themselves. Using a suite of Performance Engineering techniques, I will reveal some surprising discoveries about cosmic Kafka mysteries in our data centres, related to: cluster sizes and distribution (using Zipf’s Law), horizontal vs. vertical scalability, and predicting Kafka performance using metrics, modelling and regression techniques. These insights are relevant to Kafka developers and operators.

Safelyio Toolbox Talk Softwate & App (How To Digitize Safety Meetings)
Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/

Testing Node.js.pdf
- 2. Why Testing? ●Verification: more confidence in the absence of bugs ●Better code ●Changes can be made without risk of breaking existing features
- 3. Types of testing 1.Unit Testing Tests individual units: e.g.: compare password part of a login service 2.Integration Testing Tests a complete service or end-end feature: e.g.: complete login service
- 4. Unit Tests vs. Integration Tests Unit Tests Integration Tests Number of tests required for n components with m paths each: m*n Number of tests required for n components with m paths each: m^n?? (to be checked) Fast Slow More important than integration tests Still important to test end-end functionality
- 5. Agile and Testing ●One of the core parts of agile methodology is TDD ●To reap the benefits of agile, TDD should be followed
- 6. TDD vs. BDD ●TDD (Test driven development) is an approach that advocates writing unit tests for all functionality ●BDD (Behavior driven development) can be seen as a form of TDD that uses product-owner / backlog friendly language in tests
- 8. Testing tools Testing framework Mocha BDD library Chai (expect & should) Mocking framework Sinon.js Proxyquire Code organization JavaScript classes
- 9. Why Multi-core? ●Decrease in latency ●Test using node siege benchmarking var siege = require('siege'); // run cpu bound service benchmark siege() .on(3000) .for(1000).times .concurrent(100) .get('/') .attack();
- 10. Cluster Semantics ●Very simple to use ●Multi-core benefits with only a few lines of code ●Code divided into two sections: ○One for master process ○One for worker processes ●Various events are available to communicate between processes
- 11. Thank you
