Test Design Techniques interview questions — Easy
169 easy-level Test Design Techniques questions from our Manual Testing bank, each with the correct answer and an explanation of why it is correct.
What this covers
Test Design Techniques appears throughout Manual Testing interviews. At easy level, interviewers are typically checking that you know the fundamentals and can describe them precisely — definitions, defaults, and the basic mechanics. Work through these, then explain your answer out loud; the second part is what interviews actually test.
