In case you have a multi-module project :

let us say your module structure is

root-module
 -> a-module
 -> b-module

and the test(testToRun) you are looking to run is in b-module, with full path : com.xyz.b.module.TestClass.testToRun

As here you are interested to run the test in b-module, so you should see the tasks available for b-module.

./gradlew :b-module:tasks

The above command will list all tasks in b-module with description. And in ideal case, you will have a task named test to run the unit tests in that module.

./gradlew :b-module:test

Now, you have reached the point for running all the tests in b-module, finally you can pass a parameter to the above task to run tests which matches the certain path pattern

./gradlew :b-module:test --tests "com.xyz.b.module.TestClass.testToRun"

Now, instead of this if you run

./gradlew test --tests "com.xyz.b.module.TestClass.testToRun"

It will run the test task for both module a and b, which might result in failure as there is nothing matching the above pattern in a-module.

In versions of Gradle prior to 5  the test single system property can be used to specify a single test  You can do gradle -Dtest single ClassUnderTestTest test if you want to test single class or use regexp like gradle -Dtest single ClassName Test test you can find more examples of filtering classes for tests under this link  Gradle 5 removed this option  as it was superseded by test filtering using the --tests command line option
