Everybody please help me,

I've looked up these words for so many times, and now I'm totally confused, what are the differences between "verify", "justify", "certify", "testify"?

Thank all who concern.

    Very briefly, and very roughly:

    "Verify x is correct" - test and confirm x is correct.
    "Justify x is correct" - explain why x is correct.
    "Certify x is correct" - issue documentation to say x is correct.
    "Testify x is correct" - state that x is correct.
