Create Test Class in IntelliJ

I'm working within the traditional Maven Java project structure inside IntelliJ, e.g.

main/java/com/x/y
test/java/com/x/y

When I create a class called Foo in main/java/com/x/y using IntelliJ I would like to automatically have a file called FooTest.java created in test/java/com/x/y.

In Eclipse there is a button on the toolbar that will do much of the work involved in creating a skeleton test class, does anyone know of something similar in IntelliJ?

Thanks,

The directories structures for tests and tested classes must fit. Here is how to do it easily: stackoverflow.com/a/36057708/715269 – Gangnus

Use the menu selection Navigate -> Test, or Ctrl+Shift+T (Shift+⌘+T on Mac). This will go to the existing test class, or offer to generate it for you through a little wizard.

Alternatively you could also position the cursor onto the class name and press alt+enter (Show intention actions and quick fixes). It will suggest to Create Test.

At least works in IDEA version 12.

*IntelliJ 13 * (its paid for) We found you have to have the cursor in the actual class before ctrl+Shift+T worked.

Which seems a bit restrictive if its the only way to generate a test class. Although in retrospect it would force developers to create a test class when they write a functional class.

I can see some people have asked, so on OSX you can still go to navigate->test or use cmd+shift+T

Remember you have to be focused in the class for this to work

  1. Right click on project then select new->directory. Create a new directory and name it "test".
  2. Right click on "test" folder then select Mark Directory As->Test Sources Root
  3. Click on Navigate->Test->Create New Test
    Select Testing library(JUnit4 or any)
    Specify Class Name
    Select Member

That's it. We can modify the directory structure as per our need. Good luck!

I think you can always try the Ctrl + Shift + A to find the action/command you need.
Here you can try to press Ctrl + Shift + A and input «test» to find the command.

Use @Test annotation on one of the test methods or annotate your test class with @RunWith(JMockit.class) if using jmock. Intellij should identify that as test class & enable navigation. Also make sure junit plugin is enabled.

With the cursor on the class name declaration I do ALT + Return and my Intellij 14.1.4 offers me a popup with the option to 'Create Test'.
