RunListener.testStarted should not be called before a test's @BeforeClass

[agrieve]

Description

When using a junit RunListener, it is expected that the order of events for a test with two @Test methods be:

1. RunListener.testSuiteStarted
2. Test.beforeClass
3. RunListener.testStarted
4. Test.before
5. Test.after
6. RunListener.testFinished
7. RunListener.testStarted
8. Test.before
9. Test.after
10. RunListener.testFinished
11. Test.afterClass
12. RunListener.testSuiteFinished

However, with Robolectric (tested with 4.11.1) the first RunListener.testStarted is called before Test.setUp:

1. RunListener.testSuiteStarted
2. RunListener.testStarted
3. Test.beforeClass
4. Test.before
5. Test.after
6. RunListener.testFinished
7. RunListener.testStarted
8. Test.before
9. Test.after
10. RunListener.testFinished
11. Test.afterClass
12. RunListener.testSuiteFinished

Steps to Reproduce

Add a RunListener that logs all methods, and run a test that contains a @BeforeClass that logs as well.

Robolectric & Android Version

Robolectric 4.11.1

A bit hard since my normal environment is a chrome checkout... Here's a paste of the test I used:

import java.io.FileOutputStream;
import java.io.PrintStream;
import org.junit.runner.Description;
import org.junit.runner.notification.RunListener;

// Mark this as doNotAcquire() so the PrintStream will work.
public class ExampleTestListener extends RunListener {
    public static PrintStream PS;
    static {
        try {
            PS = new PrintStream(new FileOutputStream("/tmp/ffoo"));
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    @Override
    public void testSuiteStarted(Description description) throws Exception {
        PS.println("testSuiteStarted " + description);
    }

    @Override
    public void testSuiteFinished(Description description) throws Exception {
        PS.println("testSuiteFinished " + description);
    }

    @Override
    public void testStarted(Description description) throws Exception {
        PS.println("testStarted " + description);
    }

    @Override
    public void testFinished(Description description) throws Exception {
        PS.println("testFinished " + description);
    }
}

import org.junit.After;
import org.junit.AfterClass;
import org.junit.Assert;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.robolectric.RobolectricTestRunner;
import org.robolectric.annotation.Config;

@RunWith(RobolectricTestRunner.class)
@Config(manifest = Config.NONE)
public class ExampleTest {
    @BeforeClass
    public static void setUpClass() {
        ExampleTestListener.PS.println("setUpClass");
    }

    @AfterClass
    public static void tearDownClass() {
        ExampleTestListener.PS.println("tearDownClass");
    }

    @Before
    public void setUp() {
        ExampleTestListener.PS.println("setUp");
    }

    @After
    public void tearDown() {
        ExampleTestListener.PS.println("tearDown");
    }

    @Test
    public void test1() {
        ExampleTestListener.PS.println("test1");
    }

    @Test
    public void test2() {
        ExampleTestListener.PS.println("test2");
    }
}
