run-tests: support multiple cases in .t test Sometimes we want to run similar tests with slightly different configurations. Previously we duplicate the test files. This patch introduces special "#testcases" syntax that allows a single .t file to contain multiple test cases. Defined cases could be tested using "#if". For example, if a test should behave the same with or without an experimental flag, we can add the following to the .t header: #testcases default experimental-a #if experimental-a $ cat >> $HGRCPATH << EOF > [experimental] > feature=a > EOF #endif The "experimental-a" block won't be executed when running the "default" test case.
