Newbie question here.

In intellij there is Ctrl-Shift T to go to the corresponding test file. (For java at least.) I would like something similar in emacs. Something like this:

For a language (or project) there need to ba a mapping between source code and corresponding test code. In Ruby it could be lib and spec and in Java/Maven it would be src/main/java and src/test/java.

For a language (or project) there need to be a mapping between file names. In Ruby it could be bits_of_code.rb maps to bits_of_code_spec.rb and in Java i might be BitsOfCode.java maps to BitsOfCodeTest.java.

This (the easy part for me now - some progress at least) should be mapped to a shortcut. T seem to be taken already for character swapping so input on what mapping that would be a natural choice for an emacser is also appreciated.

I recommend Projectile for this, and much more, project-related functionality. Projectile has a binding C-c p t (projectile-toggle-between-implementation-and-test) that offers exactly what you're looking for.
