How to write an 'expected failure test'

Project Infrastructure LLVM Dev List Archives
#1

Hi devs,

I want to write a test that expected to fail. And I want to check the error message. But I found that if the command exit code is not 0, then the test will fail. Also, if I add XFAIL: *, it will not check the command line output … Can someone help me?

Most tests like this use the ‘not’ prefix in their ‘RUN’ line. Note that you may want to redirect stderr independently for these tests.
