PSA: it's now feasible to incrementally port your tests to Pants! You can combine the

skip_tests

field with this nifty query, then pipe the output into your original test runner:

./pants filter --target-type=python_test :: | \
  xargs ./pants peek | \
  jq -r '.[] | select(.skip_tests== true) | .["sources"][]'
