When defining a junit test using the static suite method android
assumes that the name of each test is also the name of a method. If
this is not the case then the test runner fails to run. The following
test class works correctly using the standard eclipse junit runner:
public class CustomTest extends TestCase
{
public CustomTest(String testName)
{
super(testName);
}
@Override
protected void runTest() throws Throwable
{
Assert.fail("Test failed");
}
public static Test suite()
{
TestSuite suite = new TestSuite();
suite.addTest(new CustomTest("test1"));
return suite;
}
}
however running using the android test runner says that test1 passes!
I have managed to trace this down to the following code in
InstrumentationTestRunner:
try {
// Look for TimedTest annotation on both test class
and test method
if
(test.getClass().getMethod(testName).isAnnotationPresent(TimedTest.class))
{
mIsTimedTest = true;
mIncludeDetailedStats =
test.getClass().getMethod(testName).getAnnotation(
TimedTest.class).includeDetailedStats();
} else if
(test.getClass().isAnnotationPresent(TimedTest.class)) {
mIsTimedTest = true;
mIncludeDetailedStats =
test.getClass().getAnnotation(
TimedTest.class).includeDetailedStats();
}
} catch (SecurityException e) {
throw new IllegalStateException(e);
} catch (NoSuchMethodException e) {
throw new IllegalStateException(e);
}
The thrown IllegalStateException doesn't seem to be caught or reported
anywhere which is I think why the eclipse plugin incorrectly reports
the tests have passed. As this code is called before the test is run
the test code is never called.
