How to write single test runner for classes with different #RunWith()? - unit-testing

Question

I wrote simple method that executes tests in my test classes: DataContainerTest.class, AnotherTest.class.
public static void main(String [] args) throws Exception {
Result result = JUnitCore.runClasses(DataContainerTest.class, AnotherTest.class);
System.out.println(result.getRunCount());
System.out.println("Total number of tests " + result.getRunCount());
System.out.println("Total number of tests failed: " + result.getFailureCount());
for(Failure failures : result.getFailures()){
System.out.println(failures.getMessage());
}
System.out.println(result.wasSuccessful());
}
This method doesn't work for my another class CommandsTest.class, where i'm using annotation #RunWith(PowerMockRunner.class). See output below:
1
Total number of tests 1
Total number of tests failed: 1
No runnable methods
false
Here is the sample of the CommandsTest.class
#RunWith(PowerMockRunner.class)
#PrepareForTest({Helper.class,
UtilsPlatform.class,
SessionManager.class,
DataContainerTest.class,
FieldObserver.class,
android.util.Log.class})
public class CommandsTest {
private static Commands2 commands;
private static License mockedLicense;
private static HSQL hsql;
#BeforeClass
public static void setUpStatic() throws Exception {
commands = new Commands2();
PowerMockito.mockStatic(UtilsPlatform.class);
PowerMockito.when(UtilsPlatform.isTablet()).thenReturn(true);
PowerMockito.mockStatic(android.util.Log.class);
PowerMockito.mockStatic(FieldObserver.class);
PowerMockito.doNothing().when(FieldObserver.class, "put", Mockito.anyInt(),
Mockito.anyInt(), Mockito.anyInt(), Mockito.anyInt(), Mockito.any(Session.class));
hsql = PowerMockito.mock(HSQL.class);
PowerMockito.when(hsql, "OnCaseOpen", Mockito.anyInt(), Mockito.anyInt(),
Mockito.anyInt()).thenReturn(false);
mockedLicense = PowerMockito.mock(License.class);
}
#Before
public void setUp() throws Exception {
PowerMockito.mockStatic(SessionManager.class);
PowerMockito.mockStatic(Helper.class);
PowerMockito.doNothing().when(Helper.class, "writeToFile", Mockito.anyString(),
Mockito.any(SocketException.class));
PowerMockito.when(Helper.class, "getLicense").thenReturn(mockedLicense);
PowerMockito.doNothing().when(Helper.class, "fieldOpened", Mockito.anyString(), Mockito.anyString());
}
#Test
public void sendKeyCombinationEventTest_nullParameters_returnOne(){
Assert.assertEquals(1, commands.sendResponse());
}
#Test
public void sendKeyCombinationEventTest_registredGuisNotNullAndOneIsLocal_returnOne(){
Assert.assertEquals(1, commands.sendKeyCombinationEvent());
}
While pressing run button in AndroidStudio, all tests are passed but my own TestRunner cannot run tests in this class.

The best way to handle classes using #RunWith(PowerMockRunner.class) annotation is just put them into default test source of your android project and then run all tests via gradle test. You don't actually need to write own test runner.
