问题
I have a VS UnitTest (MSTest) to cover some multiple threading code. With out the required locks the code fails the test 15 out 30 runs - i.e half the runs. I fix the code and the tests pass 30 times.
Now I want the test framework to run the test N time and not just once to be sure that it cant pass once out of luck. There doesn't seem to be any way to do that with an attribute on the test so I put a loop INSIDE the test to run the test code body N times.
I remove the fixes to the code (locks etc) and run the test (which loops N times) - and bam it passes. I run it again (loop N times) and it fails... Im back where I started - its still failing only half the time (even though its doing N loops through test body on each test).
What I really want is not to loop inside the test but really have the test framework load the test, run test, unload test etc N times (as I did by hand originally). How to do that? (Why isn't there just a test attribute for this - like [TestRepeatCount=5]?)
回答1:
What you really need is a Load Test. Add your unit test(s) and configure it how it will run.
You can set the number of total tests, the number of concurrent tests e.t.c.
