What is a software test engineer?

A software test engineer conducts quality assurance tests on software to make sure programs are functioning properly. The three types of testing strategies are black box, where the tester is not familiar with the software, white box, where the tester is aware of the software’s internal structure, and gray box, which is a combination of the two. Responsibilities in this job include running diagnostic tests with a critical mindset, assessing the functionality, and reporting the findings.
