How to get the path of src/test/resources directory in JUnit?

I know I can load a file from src/test/resources with:

getClass().getResource("somefile").getFile()

But how can I get the full path to the src/test/resources directory, i.e. I don't want to load a file, I just want to know the path of the directory?

Solution

  • Try working with the ClassLoader class: 

    ClassLoader classLoader = getClass().getClassLoader();
File file = new File(classLoader.getResource("somefile").getFile());
System.out.println(file.getAbsolutePath());

    A ClassLoader is responsible for loading in classes. Every class has a reference to a ClassLoader. This code returns a File from the resource directory. Calling getAbsolutePath() on it returns its absolute Path.
