Create Test Class in IntelliJ

Question

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: http://stackoverflow.com/a/36057708/715269 — Gangnus, Mar 18 '16 at 08:20

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.

In my project for some reason, even though the class and the test class are located in the same package, when I did Ctrl+Shift+T it says "No Test Class Found". Also, when I right click on the test file, it only gives me the option to compile test, but not run test. Any idea? – Glide Nov 17 '11 at 01:34

Off hand I'd answer as Andreas did at your [other question](http://stackoverflow.com/questions/8161058/intellij-mvn-project-test-classes-not-functioning). Somehow it doesn't recognize that your classes are tests. – Jarl Nov 17 '11 at 23:22
Still works nicely with 12.1.4 in Windows. Check in Settings that the Keymap binds Mainmenu/Navigate/Test to Ctrl+Shift+T – Jarl Aug 22 '13 at 11:37

Didn't work for me - _until_ I re-enabled the JUnit plugin which had somehow been disabled. – Rachel K. Westmacott Jan 14 '14 at 15:26
Works in 13.0.2 on Windows 7. – Bulwersator Feb 27 '14 at 07:06
Does not work w my IntelliJ IDEA 14 Win: I get error "No test subjects found" if I ctrl-shift-t on class or no response at all if using menu or keys on project tree. JUnit is enabled. I was able to get the Create Test popup if I clicked into class body and then used menu or ctrl-shift-t. – davidjmcclelland Nov 20 '14 at 21:40

It should be noted that *Navigate > Test* is disabled when the class is selected in the Project window. It must be selected in an editor tab. – Kevin Krumwiede Dec 22 '15 at 17:42
in the `Create Test` Dialog, how can I check all the methods at once? – ycomp Feb 10 '16 at 23:16
In IntelliJ 2020.1.2, right-click on the class name in the editor. Then Generate -> Test. – alex Jul 08 '20 at 01:47

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.

For me, this is the most logical option. I've overridden CTRL+SHIFT+T to be "restore previous tab" so the ALT+ENTER combo on the class name works well. – Scott Bennett-McLeish Apr 09 '14 at 03:28
Works on Intellij Idea 2018.2. – Zon Jan 22 '19 at 04:12

*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

Right click on project then select new->directory. Create a new directory and name it "test".
Right click on "test" folder then select Mark Directory As->Test Sources Root
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!

Thank you, I was getting "Generate tests in same root as source?" trying the above, this was just what I needed. – jgreve Feb 22 '20 at 03:36

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'.
