Reduced awareness or unintended ignorance of certain aspects can lead to inattentional blindness, or the failure to notice something that should have been visible because our attention was engaged elsewhere. As a human psychological concept, inattentional blindness also plagues testers and their mindset when testing. In my latest article for Testrail blog, I look at some steps we can take to overcome this challenge and avoid blind spots in our testing work.
It is a natural response of our brain to avoid getting overloaded with information. It automatically focuses on information that is most important while avoiding unnecessary details and noise.
In many situations, this manifests in our focus on the task at hand and its context so much that we neglect surrounding details. This is true for day-to-day activities like bumping into a pillar while looking at our phones, failing to see a swerving car when watching the road ahead… or not noticing a takeaway coffee cup in the middle of a popular television show set in ancient times!
Let’s say you are browsing through a website with the intention of looking at the layouts that must match provided mockups. While you are doing that, you may miss the following:
- The homepage of the website has an older logo of the company that should have been replaced by the newer version.
- The login box has username and password fields but the login button is missing.
- The URL structure of the website is all wonky and the individual page URLs are not named correctly.
Testers often execute tests that have defined steps and expected results, so we frequently overlook anything that is not defined and only check for the results we’re looking for. The tester’s mind is attuned to looking for specified errors, while other information or defects may tend to get missed, even though they may be right in front of our eyes.
Pick up any passed test case and try to re-execute it, but this time keep an open eye and an open mind for any new information surrounding the test. More often than not, you will find that many more defects, risk areas or questions can be found in the same area, despite the test having passed.
