Last change on this file since 18690 was 18690, checked in by taylor.smock, 13 months ago

See #16567: Convert all assertion calls to JUnit 5 (patch by gaben, modified)

The modifications are as follows:

  • Merge DomainValidatorTest.testIDN and DomainValidatorTest.testIDNJava6OrLater
  • Update some tests to use @ParameterizedTest (DomainValidatorTest)
  • Replace various exception blocks with assertThrows. These typically looked like 
        try {
        // Something that should throw an exception here
        fail("An exception should have been thrown");
    } catch (Exception e) {
        // Verify the exception matches expectations here
    }
  • Replace assertTrue(val instanceof Clazz) with assertInstanceOf
  • Replace JUnit 4 @Suite with JUnit 5 @Suite

Both the original patch and the modified patch fix various lint issues.
  • Property svn:eol-style set to native
