Can I run a single unit test from the command line for a Grails project?

Question

I've been running my Grails unit tests by typing grails test-app :unit, which runs all unit tests. Is there a way to specify a single test?

Edit: So far, everyone is basically saying the same thing, but when I do that, no tests are run. Any more thoughts?

Conclusion: OK, I was using the name of the test class, rather than the name of the class being tested. Once I tried Foo instead of FooTests it worked perfectly.

can you post the actual command line you are entering, and the output? As you can see from the answers, this should work so there is a problem somewhere before the actual typing of the command. For example what is the name of the test? what is the name of the method in the testcase? — Aaron Saunders, Sep 17 '10 at 15:02
What version are you on? I believe this feature was introduced in 1.2 release. http://www.grails.org/1.2+Release+Notes — Deepak Mittal, Sep 10 '10 at 06:13
The first comment is misleading, you can test single Unit tests with Grails 1.1.1 — seba.wagner, Jul 04 '13 at 04:14

Possibilities of things that might be wrong with your setup:

Your command order is incorrect. What works for me is:

grails test-app -unit Foo (where my test class is FooTests.groovy)
You aren't explicitly importing grails.test.GrailsUnitTestCase.

I had some problems with it recognizing my tests when I didn't import this. When I was extending GroovyTestCase, things seemed to work normally.

Working Example

Here's a sample set of tests that work for me. Perhaps you can spot some differences between them and your tests?

Note: These are all run with the testing plugin installed

test/unit/FooTests.groovy

import grails.test.GrailsUnitTestCase
class FooTest extends GrailsUnitTestCase {
    void testFoo() {
        assert true
    }

    void testBar() {
        assert true
    }
}

test/unit/BarTests.groovy

import grails.test.GrailsUnitTestCase
class BarTest extends GrailsUnitTestCase {
    void testFoo() {
        assert true
    }

    void testBar() {
        assert true
    }
}

test/unit/my/pkg/BazTests.groovy

package my.pkg

import grails.test.GrailsUnitTestCase

class BazTest extends GrailsUnitTestCase {
    void testFoo() {
        assert true
    }

    void testBar() {
        assert true
    }
}

command: all unit tests

$ grails test-app -unit
...

I tried these in Grails 1.2.3 and Grails 1.3.4, both behaved the same.

yes there is

grails test-app -unit YourController.testSomething

where YourController is your controller and testSomething is the test method.

You should see something like

Tests PASSED - view reports in

Hmm . . . not working for me. It tries to run the tests, but says passed, not finding it. – Eric Wilson Sep 09 '10 at 20:37

Given a test class foo.BarTests you can run just the tests in that class using the following command:

grails test-app :unit foo.Bar

Or run a single test method within that class using:

grails test-app :unit foo.Bar.testMethod

Note that you do not include the word "Tests" when specifying the name of test class.

This is the only way which worked for me to test a single method with Grails 3.3.6. – Ibrahim.H Nov 21 '18 at 17:15

grails test-app -unit com.package.YourController.testSomething

you need to include the package name when you run the test

I guessed that, still didn't work. Does it make a difference if it is a service class, and not generated, like a controller? – Eric Wilson Sep 09 '10 at 22:09

This would work for sure, I use it every day

Following will run a single test

grails test-app :unit ExampleControllerTests.testName

Following will run all ExampleControllerTests

grails test-app :unit ExampleControllerTests

The OP specifically said that using the name of the test class was his error, but here your examples show doing exactly that. Plus your syntax looks suspect, with a trailing colon instead of a leading dash, though I don't really know... – ErikE Feb 05 '12 at 09:20

Don't comment and vote negative if you don't really know, this works exact. Using the name of test class is no problem at all, I use it every day and i know it works. (I use grails 1.3.7) – Sudhir N Feb 05 '12 at 16:41
I don't know how to reconcile what you said with what the OP said was the definitive answer. The downvote was not for the syntax which by itself I would have ignored. – ErikE Feb 05 '12 at 19:45

Hmm, that works for me in Grails 2.0. I'm curious what version I was using 17 months ago when I was having this difficulty. @ErikE, I'd suggest that you reverse your vote, as this answer is correct, despite my previous assertions. – Eric Wilson Feb 06 '12 at 13:14
@Eric Thank you for the info! I commented in addition to downvoting to give a chance to fix the problem--if it existed. Now this has generated the chance for someone to update an answer or a question with the new information. I will never downvote unfairly if I can help it. Give some trust to the process, folks. :) – ErikE Feb 06 '12 at 17:18
This syntax works for running integration tests also, like.. `grails test-app integration: TestSpec` etc. – Ian Durkan Feb 26 '14 at 19:02

Can I run a single unit test from the command line for a Grails project?
