gradle junit category additional testtask with different categories

Question

Based on How to specify @category in test task in gradle?

I want to have 2 different test tasks:

test for the fast tests
testLongRunning for the fast and the slow tests.

I have successfully modified the buildin task test in a way that the "SlowTest"-s are onmitted:

org.namespace.some.MySlowTestClass#someReallyLongRunningTest is not executed as desired when executing task "test"

My question: Is it possible to add an additional gradle task "testLongRunning" that executes all tests (including org.namespace.some.MySlowTestClass#someReallyLongRunningTest) while the gradle task "test" does not excute the slow one?

My working example thas skips SlowTestlooks like this:

// subproject/build.gradle   
apply plugin: 'java'

dependencies {
    testCompile 'junit:junit:4.11'
}

test {
    useJUnit {
        excludeCategories 'org.junit.SlowTest' // userdefined interface in "subproject/src/test/java/org/junit/SlowTest.java"
    }
}

// subproject/src/test/java/org/junit/SlowTest.java
package org.junit;

// @Category see https://stackoverflow.com/questions/38872369/cannot-include-exclude-junit-tests-classes-by-category-using-gradle
public interface SlowTest {
 /* category marker for junit 
    via @Category(org.junit.SlowTest.class) */ 
}

// subproject/src/test/org/namespace/some/MySlowTestClass.java
package org.namespace.some;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;

import org.junit.experimental.categories.*;

public class MySlowTestClass {

    // @Category see https://stackoverflow.com/questions/38872369/cannot-include-exclude-junit-tests-classes-by-category-using-gradle
    @Category(org.junit.SlowTest.class)
    @Test
    public void someReallyLongRunningTest(){
    }
}

what i have tried:

when i add this to subproject/build.gradle

// this is line 65
task testLongRunning (type: test){
    dependsOn test
    useJUnit {
        includeCategories 'org.junit.SlowTest'
    }
}

i get this error

FAILURE: Build failed with an exception.

* Where:
Build file '...\subproject\build.gradle' line: 66

* What went wrong:
A problem occurred evaluating project ':subproject'.
> org.gradle.api.tasks.testing.Test_Decorated cannot be cast to java.lang.Class

It looks like your type might be incorrect. Try changing (type: test) to (type: Test). I think dependsOn test is trying to us the test you're passing in as the type rather than seeing it as the actual task.

Faced the same issue. The following worked for me (similar to what Tim VanDoren suggested):

test {
    useJUnit {
        includeCategories 'com.common.testing.UnitTest'
    }
}

task integrationTest (type: Test) { // Use 'Test' instead of 'test' here
    dependsOn test
    useJUnit {
        includeCategories 'com.common.testing.IntegrationTest'
    }
}

gradle junit category additional testtask with different categories
