What is the difference between “Test First” software development and “Test Driven Development (TDD)”? In this blog post, Daniel Lindner provides his opinion about this topic and discusses his issues with Test Driven Development and how he thought he could train to apply it properly.

Writing tests looks simple and every kid could write few lines of JUnit code. Writing valuable tests is more challenging. Everyone have seen (or written himself!) tests, which are hard to understand, hard to maintain, and do not verify anything really important (or maybe they do, but it is too hard to deduce)!

This chapter from the “Hitchhiker’s Guide to Python” provides recommendations on how to perform unit tests in Python and presents the unitest and doctest modules. It also lists the tools that are available to perform unit testing in Python.

The SQL Server unit tests feature have been added in the December 2012 update of SQL Server Data Tools (SSDT). This article presents a detailed information on how to create an run unit tests in SQL Server.

Test-Driven Development (TDD) is one of the main technical practice of agile software development. In his blog post, Bradley Braithwaite shared the top five Test-Driven Development mistakes based on his own experience as a consultant. These mistakes lead organizations to abandon TDD because they think that there is no return on the time invested in Test-Driven Development or the code base become more difficult to maintain.

Test Driven Development (TDD) is a powerful tool to produce quality code, but if it is not used correctly it can also put your project in a difficult position if it is not used correctly. In this article, Jakub Nabrdalik explains that TDD is simple to learn, but hard to master. He shares some tips on how to avoid Test Driven Development traps.

This article from Keith Burnell presents best practices and techniques to increase the testability of ASP.NET MVC applications. This includes how to structure the solution, architecting the code to handle the injection of dependencies and implementing dependency injection with StructureMap.

Easy Coverage is an open source framework that can dynamically generate Java unit tests to perform basic verifications. Easy Coverage is extensible and highly configurable. It can work as a standalone product or it can be used with JUnit. In his blog post, Romain Delamare explains how to dynamically generate Java unit tests with Easy Coverage.

This article explains how you can set up a unit test method that will retrieve values used in the test method from a data source using the Microsoft unit test framework for managed code. Creating these data-driven unit tests makes it easy to test a multiple inputs with a single method.
