tests/micropython: Add test for native generators.
2019-09-26 06:53:47 +00:00
# test for native generators
# simple generator with yield and return
@micropython.native
def gen1(x):
yield x
yield x + 1
return x + 2
tests: Format all Python code with black, except tests in basics subdir. This adds the Python files in the tests/ directory to be formatted with ./tools/codeformat.py. The basics/ subdirectory is excluded for now so we aren't changing too much at once. In a few places `# fmt: off`/`# fmt: on` was used where the code had special formatting for readability or where the test was actually testing the specific formatting.
