JSON requires that keys of objects be strings. CPython will therefore automatically quote simple types (NoneType, bool, int, float) when they are used directly as keys in JSON output. To prevent subtle bugs and emit compliant JSON, MicroPython should at least test for such keys so they aren't silently let through. Then doing the actual quoting is a similar cost to raising an exception, so that's what is implemented by this patch. Fixes issue #4790.
This directory contains tests for various functionality areas of MicroPython. To run all stable tests, run "run-tests" script in this directory. Tests of capabilities not supported on all platforms should be written to check for the capability being present. If it is not, the test should merely output 'SKIP' followed by the line terminator, and call sys.exit() to raise SystemExit, instead of attempting to test the missing capability. The testing framework (run-tests in this directory, test_main.c in qemu_arm) recognizes this as a skipped test. There are a few features for which this mechanism cannot be used to condition a test. The run-tests script uses small scripts in the feature_check directory to check whether each such feature is present, and skips the relevant tests if not. When creating new tests, anything that relies on float support should go in the float/ subdirectory. Anything that relies on import x, where x is not a built-in module, should go in the import/ subdirectory.
