Not able to get expected expections to work..

[Kartik Kumar]

I have a test that is failing and I hope that some can help. The test attempts to verify that AssertionError is raised but TestNGException is raised instead.

The test in question:

 @Test(

      expectedExceptions = AssertionError.class,

      expectedExceptionsMessageRegExp =

          "expected not to match regex <a(.)> but was <ab>")

  public void testNotMatchesRegexFailure() throws Exception {

    try {

      System.out.println("################ \n Begin");

      TestNGAsserts.assertNotMatchesRegex("a(.)", "ab");

    } catch (AssertionError e) {

      Assert.assertEquals(

          "expected not to match regex <a(.)> but was <ab>",

          e.getMessage()); // This works.

      System.out.println("end test " + e + "\n##########");

      throw e;

    }

  }

The output when running an Maven via command line or in IntelliJ

################

 Begin

end test java.lang.AssertionError: expected not to match regex <a(.)> but was <ab>

##########

The stack trace is given below

Expected exception java.lang.AssertionError but got org.testng.TestException: The exception was thrown with the wrong message: expected "expected to match regex <a(.)> but was:null" but got "expected to match regex <a(.)> but was:null"

I wrote additional testng assertions. Should those assertions fail, then AssertionError is thrown. In my unit tests, I check if AssertionError is thrown.

The tests work if I use try/catch verify model but when I use TestNG's expected exceptions attribute

[Krishnan Mahadevan]

If you wrote additional assertions then those assertions should still fail a test by itself. Why do you need a try.. Catch here? Am still not getting it. What exactly are you gaining by checking if assertion error was thrown when TestNG by itself looks for that as well ?

I don't need it. I wanted to check if the AssertionError is raised. It is raised by the function. But AssertionError is replaced by TestNGException. The try/catch block merely verifies that AssertionError is raised.
