What is the difference between Regression testing vs. Smoke
testing?

Answer Posted / anand kiran

regression testing: regression testing means as a tester once verify previous passed tests after defect fixed again this time passed or not once you check it.
ex:total 10 test cases
1 to 9 passed and 10th is failed after defect fixed.
again this time also 1 to 9 passed or not once you verify this is called regression testing.
smoke testing: smoke testing means this testing is done developer.Because after receive defect from tester then that defect was fixed before release note or modified build to tester once verify or check it his/her self because any side effects had come or not.those side effects was effect on remaining test cases.So once your own self check it defect correctly fixed or not this is called smoke testing.
