Gradle Goodness: Running All Tests From One Package

Hubert Klein Ikkink shows how to run all tests in Gradle from one package, complete with a set of instructions for different scenarios.

In response to accelerated release cycles, a new set of testing capabilities is now required to deliver quality at speed. This is why there is a shake-up in the testing tools landscape—and a new leader has emerged in the just released Gartner Magic Quadrant for Software Test Automation.

If we have a Gradle task of type Test we can use a filter on the command line when we invoke the task. We define a filter using the --tests option. If, for example, we want to run all tests from a single package, we must define the package name as value for the --tests option. It is good to define the filter between quotes, so it is interpreted as is, without any shell interference.

If we configure the test task to output the test class name, we can see that which tests are executed. In the following snippet, we reconfigure the test task:

...
test {
    beforeTest { descriptor ->
       logger.lifecycle("Running test: $descriptor.className")
    }
}
...

Suppose we have a project and we execute all tests:

$ gradle test
...
:test
Running test: mrhaki.gradle.model.CourseSpec
Running test: mrhaki.gradle.model.TeacherSpec
Running test: mrhaki.gradle.service.CourseServiceSpec
...
$

To only run the tests in the mrhaki.gradle.model package, we use the following command:

$ gradle test --tests "mrhaki.gradle.model.*"
...
:test
Running test: mrhaki.gradle.model.CourseSpec
Running test: mrhaki.gradle.model.TeacherSpec
...
$

We can even filter on a single test to be executed:

$ gradle test --tests "mrhaki.gradle.model.CourseSpec"
...
:test
Running test: mrhaki.gradle.model.CourseSpec
...
$

If we only want to run a single method of a test, we can specify the method name as a filter:

$ gradle test --tests "test --tests "mrhaki.gradle.model.CourseSpec.create new Course as immutable""
...
:test
Running test: mrhaki.gradle.model.CourseSpec
...
$
