Selenium is a popular framework for testing the user interface (UI) of a web application. It is an extremely powerful tool for running end-to-end functional tests. You can write tests in several programming languages and Selenium executes them into one or multiple browsers.
James A. Whittaker, the former Test Director for Chrome and Chrome OS, discusses in this article what it means to be a Google tester and how Google testers approach the problems of scale, complexity and mass usage.
The open source JUnit unit testing tool has been a blessing for Java developers. However, many programmers think that it is enough to learn the JUnit API and write a few tests in order to have a well-tested application. This idea is more dangerous than not doing unit tests because it leads to a wrong sense of code quality. Learning JUnit is the easiest part of unit testing your Java code, but writing good tests is the hard part.
This article provides a process to integrate Test-Driven Development in the maintenance of a .NET application. You will first write the tests that will prove your new code gets the same results as the legacy code. Then you isolate new code into separate methods or classes that you can test independently. You break down the requirements into simple valid tests. Finally you check to see that you have not introduced a new bug. While you are doing this, let Visual Studio generate the utility code for you and find a tool to run your tests continuously like AutoTest.NET.
This article discusses the traditional software testing aspects that should be changed before adopting Agile practices. Testing teams face a significant impediment when they have to unlearn the traditional practices.
Issues with testability in Java boil down to our inability to write tests or the excess trouble we have to go through to get it done. In this article, based on chapter 7 of the book “Effective Unit Testing – A guide for Java developers”, Lasse Koskela shares a set of dos and don’ts for testable design. In the tips provided, he recommends to avoid complex private methods, static methods, logic in constructors and to favor composition over inheritance.
Unit tests are useful and effective if you remember to make them FIRST. FIRST is an acronym for Fast, Isolated, Repeatable, Self-Verifying and Timely. Each of this points is discussed in the article with examples. The most important thing about unit tests is that they be useful and effective for your programming team. The FIRST mnemonic is a simple mechanism to guide you there.
