If you are an automation tester, you will need to write a lot of code to cover the required test scenarios and test cases. Your code base will grow and grow, but some of the code will not be really needed and thorough code reviews should be done, to avoid unnecessary code.
Such unneeded code might include forgotten and unused imports, duplicate code that should have been extracted in a separate method or variables that are declared only to be used in one place.

Coding standards are something both automating testers and developers should adhere to. Pretty obvious right? Maybe not that obvious might be some of the rules you should follow when writing the code for your tests. Checkstyle is here to help in standardizing your code, so that you can get an early feedback regarding code improvements (earlier than the code review step anyway). It allows you to define a set of basic coding rules that must be followed in your project, and it gives you the opportunity to make your builds fail if someone breaks those rules. This post addresses using checkstyle from a Maven project, by means of the dedicated Maven plugin that you need to declare in your project. Continue reading Using Maven checkstyle in your project to help adhere to coding standards
A considerable amount of tests will need some test data to be generated previous to them running. Some people prefer to put all the data creation for all the tests in a class into the @BeforeClass method, some others prefer to keep the prerequisite data creation inside the tests themselves. Continue reading Better Test Code Principles: #2 Don’t generate ALL your test data in @BeforeClass
When starting to learn Java, one of the first things you are taught is that a class consists of several things, among which are the ‘methods’. A method is nothing more than grouping of several code lines. Since tests are code, the same principle applies to writing your Java based tests. Especially if you are dealing with duplicate code (code you keep copy/pasting all across your test project).
So what would be the reasons for not wanting to duplicate your code, but instead grouping it into methods: Continue reading Better Test Code Principles: #1 Don’t copy/paste the code. Reuse it.
