在一次对手动测试员简介的采访中,我被问到一个问题,“您使用哪种技术来准备测试用例?”
这个问题的可能答案是什么?
This question is very broad and could have several completely different answers.
In short: you don't prepare the testcase, you prepare the test environment.
If the question actually is about designing and/or writing test cases then the answer gets more complex and can not be summarized in a forum post.
Regarding "covering all possible inputs range", most of the time this is not possible and not desirable, you are better of testing boundary values and/or choosing another approach.
For more information, you should probably read the ISTQB Syllabus: http://www.istqb.org/downloads/finish/16/15.html
