diff tests/run-tests.py @ 32704:1270b00a385d

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
run-tests: add a way to list tests, with JSON and XUnit support Some test runners are interested in listing tests, so they can do their own filtering on top (usually based on attributes like historically observed runtime). Add support for that.
