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.

Answer 1

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 ...  Starting unit test phase ...  ------------------------------------------------------- Running 6 unit tests... Running test my.pkg.BazTest...PASSED Running test FooTest...PASSED Running test BarTest...PASSED Tests Completed in 847ms ... ------------------------------------------------------- Tests passed: 6 Tests failed: 0 -------------------------------------------------------  ... Tests PASSED - view reports in target/test-reports 

command: Foo unit tests

$ grails test-app -unit Foo ...  Starting unit test phase ...  ------------------------------------------------------- Running 1 unit test... Running test FooTest...PASSED Tests Completed in 815ms ... ------------------------------------------------------- Tests passed: 2 Tests failed: 0 -------------------------------------------------------  ... Tests PASSED - view reports in target/test-reports 

command: my.pkg.Baz unit tests

$ grails test-app -unit my.pkg.Baz ...  Starting unit test phase ...  ------------------------------------------------------- Running 2 unit tests... Running test my.pkg.BazTest...PASSED Tests Completed in 842ms ... ------------------------------------------------------- Tests passed: 2 Tests failed: 0 -------------------------------------------------------  ... Tests PASSED - view reports in target/test-reports 

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

Answer 2

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
