How to configure gradle to output total number of tests executed?

Question

While tests are running, the number of tests run so far is ephemerally displayed, but how can I print the total number of tests that were run to the console after all tests have run?

Configuring testLogging doesn't help. I can make gradle output a result for every test, like this:

testLogging {
    events "passed", "skipped", "failed"
}

But I want a summary "bottom line", that outputs the total number of tests that were run, even if they all passed.

You may use afterSuite closure with TestResult argument. F.e. (borrowed from https://gist.github.com/orip/4951642):

test {
  testLogging {
    afterSuite { desc, result ->
      if (!desc.parent) { // will match the outermost suite
        println "Results: ${result.resultType} (${result.testCount} tests, ${result.successfulTestCount} successes, ${result.failedTestCount} failures, ${result.skippedTestCount} skipped)"
      }
    }
  }
}
