Summary
The qemu-arm and qemu-riscv ports generate a whole lot of .exp files in the
tests/directory when you run the tests on these ports. This leaves the repo in an unclean state.This PR improves this situation by:
tools/tinytest-codegen.pyscript by calling out to Python to run them and collecting the resulting stdout outputbuild/genhdr/tests.hfileThis results in a clean repo after running the tests. It also means that
run-tests.pyno longer needs a special case to handle the allowed tests for qemu-arm/riscv targets.A bonus of this approach is that it's not much extra work to enable running the tests on qemu-* port using the via .mpy and via native emitter test framework that already exists in
run-tests.py.Note: this PR builds on #15577.
TODO:
Testing
The qemu-arm tests pass like they did before, but no stray .exp files are generated.
Trade-offs and Alternatives
It's a little slower this way when generating the .exp files but not by much.
An alternative to this approach would be to make the qemu-* ports have a stdio to the outside world for the REPL, then treat the qemu process as a board with a serial port, and run the test suite as it would normally be run for an attached hardware board.
