Check stepMismatch results for type=time. On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". Empty values PASS stepMismatchFor("", null, null) is false PASS stepMismatchFor("", "2", "12:34:56") is false Normal step values PASS stepMismatchFor("12:34:55", "1", "12:34:56") is false PASS stepMismatchFor("12:34:55.001", "1", "12:34:56") is true PASS stepMismatchFor("12:34:56.001", "0.001", "12:34:56") is false PASS stepMismatchFor("12:34:55", "0.333", "12:34:56") is true PASS stepMismatchFor("12:34:55.001", "0.333", "12:34:56") is false PASS stepMismatchFor("12:34", "86400", "12:34") is false PASS stepMismatchFor("23:59:59.998", "86399.999", "00:00") is true PASS stepMismatchFor("23:59:59.999", "86399.999", "00:00") is false Implicit step base PASS stepMismatchFor("12:34", "120", null) is false PASS stepMismatchFor("12:35", "120", null) is true Small step values PASS stepMismatchFor("12:34:55.001", "0.0003", "12:34.55.000") is false PASS stepMismatchFor("12:34:55.001", "0.0019", "12:34.55.000") is true PASS stepMismatchFor("12:34:55.004", "0.0019", "12:34.55.000") is false Invalid or no step values PASS stepMismatchFor("12:34", null, "12:34") is false PASS stepMismatchFor("12:34:56", null, "12:34") is true PASS stepMismatchFor("12:34", "-1", "12:34") is false PASS stepMismatchFor("12:34", "foo", "12:34") is false Special step value PASS stepMismatchFor("12:35", "any", "12:34") is false Disabled PASS stepMismatchFor("12:34:55.001", "1", "12:34:56", true) is true PASS successfullyParsed is true TEST COMPLETE
