primitive arrays cause ClassCastException in eclipse 6.8.1 plugin #363

Closed willkil closed 5 years ago

I created an eclipse project that has the following simple test:

@DataProvider(name = "byteArrayTest")
public Object[][] byteArrayTestDataProvider() {
    return new Object[][] {
        { "1", new byte[] { 1 } },
    };
}

@Test(dataProvider = "byteArrayTest")
public void byteArrayTest(String s, byte[] bytes) {
    System.out.println("BEFORE");
    assertTrue("1".equals(s) && bytes[0] == 1);
    System.out.println("AFTER");
}

This test succeeds as expected from the command line in 6.8.1 and using Eclipse's Run As->TestNG Test in 6.8.0.

Using Eclipse's Run As->TestNG Test with 6.8.1, however, yields the following ClassCastException:

The "BEFORE" and "AFTER" println()s never occur, so the test doesn't actually run.

A workaround is to use Byte[] instead of byte[].
