How to Reproduce a Non-Reproducible Defect and Make Your Testing Effort Worth It

In the world of software testing, a defect once found should be consistently reproducible so the tester can report with conviction, a developer can fix with clarity and the QA team can close with confidence.

However, this process sometimes comes with its own set of challenges. This article tries to illuminate those dark areas of defect reproduction.

First of all, what is “Reproducing a Defect”?

If a certain sequence of steps has landed the tester at a point where a deviation in expected behavior is observed- the “steps to reproduce” is the defect field that contains a record of this exact sequence of steps. If we encounter the same problem, every time we follow those steps, then this is called the reproducible defect.

In addition to steps to reproduce more evidence such as data used, screenshots or screen recorded videos can be provided too. In case this information is found inconsistent or incorrect, the bugs could get discounted and marked as invalid without a further resolution.

Therefore, ‘steps to reproduce’ is critical and the following are some of the points to keep in mind when writing this part of the defect report:

How to write defect “Steps to Reproduce”:

An incorrectly written “Steps to reproduce” could not just jeopardize the validity of the defect but also involve a lot of time wasted in terms of seeking out clarifications and answers regarding things that aren’t clearly mentioned.

Why reproducing a Defect is so important?

Now, let us find out ‘Why reproducing a Defect is so important?’

Speaking technically, if you can’t reproduce a bug, you can never fix it.

The following are some of the factors that determine if a defect gets fixed:

What are ‘Non-Reproducible’ bugs/defects?

Every tester must have experienced these situations:



In all these cases, it is hard to determine the exact condition and report it right. Such issues/defects take a lot of time in the investigation of. These types of issues can’t be ignored, as the end- user/customer may observe them too.

How to Reproduce a Defect?

A few things that might help are:

Additionally:

Conclusion:

With the overall discussion, it can be clearly concluded that it is very important to ‘reproduce a bug’ in order to get that bug validated and then fixed. If the bug is not reproducible, then the testing effort used in finding, analyzing and reporting that particular bug/defect is a total waste.

For understanding and reproducing a bug, it is essential to have detailed and properly explained ‘Steps to Reproduce’, state and environment in which the bug occurred. It is possible to fix a not reproducible defect, but it can be very time to consume as well as a very difficult task. Another most important factor is proper communication without which, a valid bug can be invalidated.

So, to make your testing effort in finding defects worth it, the above mentioned can be helpful.
