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:<

Answer 1

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.

Answer 2

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

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

Answer 3

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.

Answer 4

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

Answer 5

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
