Tests That Formerly Passed Now Fail

If your test passed in versions of DTM before 2.2 and now fails, it may have zero returns or out-of-context errors. The way that DTM Logger handles these test results has been changed for the following reasons:

Zero-Return Failures

With the release of DTM 2.2, logs with all zero counts (0 pass, 0 fail, 0 skip, 0 block) are now considered to be failures rather than passes. This change is because an all-zero return typically implies that something is wrong with a test or the test has had an early catastrophic failure. This behavior is the same behavior that is found in logs elsewhere in DTM.

Out-of-Context Failures

Previously, DTM ignored DTM Logger failures that were reported out of context. This situation caused a log with out-of-context failures to still report a pass in DTM. With DTM 2.2, this behavior has changed so that DTM now reports a failure in the case of out-of-context failures. By considering out-of-context failures as failures in DTM, DTM can report test status with greater accuracy.

To solve this problem, you will need to re-evaluate your driver on the basis of a failed test result.
