QA engineers employ a diverse variety of techniques in their job. Let’s look at some of the more notable ones in pairs. The ideal method is to employ them in tandem.Testing in a black box versus testing in a white box Black box testing is carried out without knowledge of the system design, considering it as a “black box.” The code is not visible to the QA. They just interact with the UI to see if the website performs as it should.White box (aka structural) testing, on the other hand, is done with the internal logic and structure of the code already known. This manner, they can figure out which part of the code isn’t working properly.

The QA engineer is directed by the specific situations and actions established in advance during scripted testing. Everything is well documented.Exploratory testing, on the other hand, allows the QA to apply their instincts when browsing the website. This can sometimes provide a fresh perspective and identify flaws not covered by written test cases. Manual testing vs. automated testing Humans execute manual testing by following test cases and methods. It is useful for usability and exploratory testing and has the best price/quality ratio for small jobs.Automation tools and scripts are used to do automated testing. Its benefits include excellent precision, dependability, and quickness. Tests can be repeated once they have been written.
