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.
