"""Convert Unity test-runner output to JUnit XML.

|
|
Usage:
|
|
./test_binary | python3 unity_to_junit.py <suite_name> <output.xml> [elapsed_seconds]
|
|
|
|
Unity emits one result line per test:
|
|
path/to/file.c:LINE:TEST_NAME:PASS
|
|
path/to/file.c:LINE:TEST_NAME:FAIL:message
|
|
path/to/file.c:LINE:TEST_NAME:IGNORE:message

followed by a summary line:
|
|
N Tests N Failures N Ignored
