Test-driven development (TDD) involves writing unit tests before writing code to help ensure code quality and avoid omitted tests. The document discusses the NUnit testing framework for .NET, which uses attributes to identify test fixtures, methods, and setup/teardown functionality. It also covers how to write tests using assertions and run tests using the NUnit GUI or console applications.
Model-based testing can be a powerful alternative to just writing test cases. However, modeling tools are specialized and not suitable for everyone. On the other hand, keyword-driven test automation has gained wide acceptance as a powerful way to create maintainable automated tests, and, unlike models, keywords are simple to use. Hans Buwalda demonstrates different ways that keyword testing and models can be combined to make model-based testing more readily accessible. Learn how you can use keywords to create the models directly. The results of this "poor man's approach" to model-based testing are clean, concise test cases that are interpreted dynamically. In other words, the model executes the tests rather than generating the tests for execution by another tool. This allows the model to actively respond to changing conditions in the application under test. See this demonstrated with a simple state-transition model, written with keywords, that plays a game until all relevant situations have been visited.
The document discusses acceptance testing with Selenium. It provides examples of unit testing code with assertions to validate functionality. It explains that acceptance tests are written from the user perspective to validate requirements and are performed near the end of a project by the customer before accepting delivery. Selenium allows automating acceptance tests by controlling browsers to simulate user actions and verify outcomes.
The document summarizes a series of talks on software testing. The talks will cover the different stages of the test life cycle, including: decomposing the system into independent units; building tests for formal models; establishing testability through test harnesses; automating tests using frameworks; and including tests in continuous integration. The document then provides more details about the second talk on building tests for formal models and describes the use of formal models in test design techniques.

Sociology Essays - Mental health & illness within SociologyUKEssays
The document compares and contrasts two sociological approaches to mental health and illness: social reaction (labeling) theory and social constructivism. Social reaction theory views mental illness as arising from the social reaction of labeling someone as deviant, leading to secondary deviance, while social constructivism sees mental illness as entirely socially constructed through discourses and power relations with no primary deviance. Both theories are critical of mainstream views, but social constructivism is more radical in rejecting any physical or biological basis for mental disorders. The theories differ in their theoretical frameworks and implications for understanding the origins and nature of mental illness.

Test Driven Development (TDD) Preso 360|Flex 2010guest5639fa9
This document discusses Test Driven Development (TDD) using FlexUnit 4. It provides an overview of TDD and its benefits. It then walks through an example of building a Twitter client application using TDD. It demonstrates how to create test suites and test cases, write tests to fail initially, then write code to pass the tests. It covers concepts like user stories, assertions, refactoring tests. The document recommends TDD for APIs, frameworks and services, but not GUI testing. It provides resources to learn more about TDD with FlexUnit 4 and Adobe technologies.
The document discusses why software developers should use FlexUnit, an automated unit testing framework for Flex and ActionScript projects. It notes that developers spend 80% of their time debugging code and that errors found later in the development process can cost 100x more to fix than early errors. FlexUnit allows developers to automate unit tests so that tests can be run continually, finding errors sooner when they are cheaper to fix. Writing automated tests also encourages developers to write better structured, more testable and maintainable code. FlexUnit provides a testing architecture and APIs to facilitate automated unit and integration testing as well as different test runners and listeners to output test results.

CAKE: Sharing Slices of Confidential Data on BlockchainClaudio Di Ciccio
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

39. Example User Story 08 As a: Mobile phone user I want to: receive a list of 3 places to eat at less than 30min from where me and the contacts I select are So that: I can propose my contacts to meet there
40.
41. Use Acceptance Test to drive Behavior (more on how to do this in your projects in part 2) 08 Test 0.2: implement what you need as stubs and pass the tests for all thinkable scenarios (you wrote the top layer of your app as) ... result= nearUsApp.find(selectedContacts,"placeToEat",30m) if result.length<1 { showMsg("ERROR: no places found") } else { ... ui.showList(m) } (now you can use mock objects like) ... phoneDriver.getContacts(){ return ["Juan35m","Pedro20m"]} ui.selectFromList(l) { return l[0] } nearUsApp.find(contacts, kindOfPlace, timeToGetThereMax) { if (contacts[0]=="Juan35m") { return [] } return [...3 lugares...] //you must try none, 3 near, etc. } And TEST that running the application code you already wrote with different inputs (selecting different contacts) gives the expected results (no places to meet Juan35m in less tha 30min, etc.)
42.
43. Use System Tests to drive Architecture (more on how to do this in your projects in part 2) 08 How do you get all the information the past tests show you need? How do you transport it from one place to another? Are the tools you intend to use available in the all target environments? How reliable are this tools? How fast? Can you accommodate more than one alternative? Test: write tests connecting to all the needed data sources and services, check your app understands all the results and errors Test: deploy simple stress test applications using each of the tools you may use to the target environments Test: stress test the architecture implement all the communications and data handling required by the components, using stubs only to simulate errors and ensuring you return data for all the relevant scenarios So: the team is sure the tools work, the application can be deployed, what are the performance limits, etc.
44.
45. Use Integration Tests to drive Design (more on how to do this in your projects in part 2) 08 Test: write tests to define which requests and responses must support each component of your application Use simple drivers for the requests and stubs to return examples for all the possible responses So: the team can work simultaneously in various components without integration problems the contracts and dependencies for the components are clear you can refactor anything inside as long as you respect the interface (pass the tests)
46.
47. Use Unit Tests to find the best implementation (more on how to do this in your projects in part 2) 08 Test: write tests to understand what do you need of each class and method Test: write tests to show what inputs and outputs are supported So: anyone can use, extend or modify any class or component without breaking something your code is free of defects you write only what you need in some cases you can have more than one implementation (e.g. critical algorithms, drivers, transport/communication protocols)
