JUnit Ordered Test Runner
An application to provide support for executing tests in the specific order and generate the customized XML report.

Sample Usage
- The
OrderedTestRunner
should be used to run the test. The order of each test can be set by the@Order
annotation. The test with lower order value is run first. - Run the tests with
TestWatcher
rule using@Rule
annotation. - Register the test class using the
registerClass
method ofTestWatcher
in the@BeforeClass
setup. - Finally, invoke the
createReport
method ofTestWatcher
in the@AfterClass
setup.
For example,
@RunWith(OrderedTestRunner.class)
public class SampleOrderedTest {
@Rule
public TestWatcher watchman = TestWatchman.watchman;
public SampleOrderedTest() {
}
@BeforeClass
public static void setUpClass() {
TestWatchman.watchman.registerClass(SampleOrderedTest.class);
}
@AfterClass
public static void tearDownClass() {
TestWatchman.watchman.createReport(SampleOrderedTest.class);
}
@Test
@Order(1)
public void firstTest() {
assertTrue(0 == 0);
}
@Test
@Order(2)
public void secondTest() {
assertEquals(1, 1);
}
@Test
@Ordered(3)
public void thirdTest() {
assertNotEquals(1, null);
}
}
Also,
- If a
Runner
is already being used to run the tests, then, an inner class can be used to run withOrderedTestRunner
. Tests can be triggered using theJUnitCore.runClasses
method. In this case, the test is always passing, so optional check can be performed usingallTestSucceeded
.
For example,
public class SampleOrderedTest {
public SampleOrderedTest() {
}
@BeforeClass
public static void setUpClass() {
TestWatchman.watchman.registerClass(SampleOrderedTest.class);
}
@AfterClass
public static void tearDownClass() {
TestWatchman.watchman.createReport(SampleOrderedTest.class);
}
@Test
public void startTest() {
JUnitCore.runClasses(TestHelper.class);
assertTrue(TestWatchman.watchman.allTestsSucceeded());
}
@RunWith(OrderedTestRunner.class)
public static class TestHelper {
@Rule
public TestWatcher watchman = TestWatchman.watchman;
@Test
@Order(1)
public void firstTest() {
assertTrue(0 == 0);
}
@Test
@Order(3)
public void thirdTest() {
assertNotEquals(1, null);
}
@Test
@Order(2)
public void secondTest() {
assertEquals(1, 1);
}
}
}
And,
- When some tests are not assigned an order, then, these are run after the tests with an assigned order.
You can refer the given test examples for better understanding of writing tests with OrderedTestRunner
.
Report Generation
- The
TestWatcher
generates an XML report in thetarget/hackerrank-report
directory. The filename isTEST-{test-class-canonical-name}.xml
. - When running tests in a suite, suite report, as well as individual test reports, will be generated.
Building Project
- Use
mvn clean build
to build the project. - Use
mvn clean test
to run the tests. - Use
mvn clean test -Dtest=TestSuite
to run the suite.
