Chapter 13. Concurrency > Testing Threaded Code

Testing Threaded Code

Proving that code is correct is impractical. Testing does not guarantee correctness. However, good testing can minimize risk. This is all true in a single-threaded solution. As soon as there are two or more threads using the same code and working with shared data, things get substantially more complex.

Recommendation: Write tests that have the potential to expose problems and then run them frequently, with different programatic configurations and system configurations and load. If tests ever fail, track down the failure. Don’t ignore a failure just because the tests pass on a subsequent run.
