Test classes not found when using testng:6.1.1, but are found (and run correctly) when using junit:4.11

Dead simple build.gradle:

apply plugin: 'java'
apply plugin: 'idea'
  repositories {
    mavenCentral()
}
  dependencies {
    testCompile 'junit:junit:4.11'
    testCompile 'org.testng:testng:6.1.1'
}

Dead simple test:

import org.testng.Assert;
import org.testng.annotations.Test;
  public class MainTest {
    @Test
    public void testMain() {
        Assert.fail("fail");
    }
}

run gradle test via command line or through intellij. result:

But if I switch ONLY the imports to junit, like so:

import org.junit.Assert;
import org.junit.Test;
  public class MainTest {
    @Test
    public void testMain() {
        Assert.fail("fail");
    }
}

and run gradle test, I get the appropriate error:

com.seanpont.disnetty.MainTest > testMain FAILED
    java.lang.AssertionError at MainTest.java:10
  1 test completed, 1 failed
:test FAILED
  FAILURE: Build failed with an exception.
  * What went wrong:
Execution failed for task ':test'.
> There were failing tests. See the report at: file:///C:/workspace/disnetty/dispeptic/build/reports/tests/index.html
  * Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

TestNG support is activated with ‘test { useTestNG() }’. See the ‘Test’ task in the Gradle Build Language Reference.

Thank you.
