This file tests the behavior of run-tests.py itself.

Avoid interference from actual test env:

  $ . "$TESTDIR/helper-runtests.sh"

Smoke test with install
============
  $ "$PYTHON" $TESTDIR/run-tests.py $HGTEST_RUN_TESTS_PURE -l
  running 0 tests using 0 parallel processes 
  
  # Ran 0 tests, 0 skipped, 0 failed.

Define a helper to avoid the install step
=============
  $ rt()
  > {
  >     "$PYTHON" $TESTDIR/run-tests.py --with-hg=$HGTEST_REAL_HG -j1 "$@"
  > }
