How to deal with the test data in Junit?

Question

In TDD(Test Driven Development) development process, how to deal with the test data? Assumption that a scenario, parse a log file to get the needed column. For a strong test

Answer 1

Maven, for example, uses a convention for folder structures that takes care of test data:

src
  main
    java           <-- java source files of main application
    resources      <-- resource files for application (logger config, etc)
  test
    java           <-- test suites and classes
    resources      <-- additional resources for testing

If you use maven for building, you'll want to place the test resources in the right folder, if your building with something different, you may want to use this structure as it is more than just a maven convention, to my opinion it's close to 'best practise'.
