Who designed the first English-language data-processing compiler and coined the word bug?
Rear Admiral Grace Murray Hopper developed the COBOL (Common-Business Oriented Language) on the MARK I & MARK II Mainframe computers. A moth got into the electronics and caused the program to stop. The BUG was retrieved and pasted in the log book. Thus the terms: BUG (there's an error in the program) & DE-BUG( find the errors in a computer program).
What is the difference between stress testing and regression testing in software engineering?
Regression testing is intended to uncover any bug that may have been introduced in the application as a side effect of fixing some other bug. So all the test cases are run. This is different from Unit testing, where we run only unit tests for the unit where we fixed the bug. Stress testing stresses particular functionality so see where is will break etc. For example a good stress test for MS Word may be to open a file in MS Word and keep writing text to it till it breaks.
