Stop Suite Execution After First Failure In TestNG - ant

Question

I am using Ant to execute a set of TestNG tests as follows:
<testng suitename="functional_test_suite" outputdir="${basedir}/target/"
classpathref="maven.test.classpath" dumpCommand="false" verbose="2"
haltonfailure="true" haltonskipped="false" parallel="methods" threadCount="2">
<classfileset dir="${basedir}/target/test-classes/">
<include name="**/*Test.class" />
</classfileset>
I would like for the tests to stop immediately after the first failure. haltonfailure does not seem to do the trick, it just halts the ant build if the whole suite has test failures. Is there any way I can halt the suite execution on first failure?
Thanks

Answer 1

You can set dependencies on your individual test methods. testng dependencies. This will only run test methods if desired dependencies passed.

Answer 2

You can use a suite listener for this purpose.
public class SuiteListener implements IInvokedMethodListener {
private boolean hasFailures = false;
#Override
public void beforeInvocation(IInvokedMethod method, ITestResult testResult) {
synchronized (this) {
if (hasFailures) {
throw new SkipException("Skipping this test");
}
}
}
#Override
public void afterInvocation(IInvokedMethod method, ITestResult testResult) {
if (method.isTestMethod() && !testResult.isSuccess()) {
synchronized (this) {
hasFailures = true;
}
}
}
}
#Listeners(SuiteListener.class)
public class MyTest {
#Test
public void test1() {
Assert.assertEquals(1, 1);
}
#Test
public void test2() {
Assert.assertEquals(1, 2); // Fail test
}
#Test
public void test3() {
// This test will be skipped
Assert.assertEquals(1, 1);
}
}
