How do you debug a failing Ranorex test?

Debugging starts with the Report rather than re-running blindly: the failed step's logged RanoreXPath, error message, and attached screenshot usually narrow the problem down to one of a few causes before any code is touched.

If the report alone isn't conclusive, running the test case in Studio's Debug mode lets a tester set breakpoints inside code modules, step through execution, and inspect variables in the Watch window at the exact moment the failure would occur - useful when the issue is a value being wrong rather than an element being missing.

When the suspicion is a locator problem specifically, reopening the target application in Ranorex Spy and re-checking the failing RanoreXPath against the current UI will confirm whether the element's attributes changed, whether the path now matches more than one element, or whether it simply loads more slowly than the configured timeout allows.

Distinguishing a timing issue from a real application bug is the key judgment call: if increasing the timeout consistently fixes the failure, it was a synchronization problem; if the element genuinely isn't there or the value is genuinely wrong even after waiting, the application itself has regressed.
