I've always heard this called regression testing. We had an interesting case at Realia COBOL because the compiler itself was written in COBOL. So you couldn't simply compare outputs, you had to compare the output of the output. I myself worked on the debugger and the compiler frontend person was my best user. When she had a problem I'd be debugging the debugger debugging the compiler compiling the compiler.

@qj0n I am only speaking from decades of experience working on compiler, jvm, and platform internals. Perhaps the wikipedia author had a different experience. Please note the first words of my original reply were "I've always heard".

 @qj0n Regression tests test only for regressions, not correctness. Compliance or conformance tests test for correctness.

@qj0n Your memory is quite different from mine. In my experience CS has had a different standing in the industry: "Those who cannot do, teach".
