Coverage Analysis

ArduPilot provides an easy way to run automated checks to generate coverage analysis.

These are used to produce a periodically-updated report on our firmware server.

coveralls.io also uses the same mechanisms to generate its own report

Running Coverage Analysis

Run the full suite with:

./Tools/scripts/run_coverage.py --full

This generates data files describing the coverage, but also creates a HTML report for easy perusal.

firefox reports/lcov-report/index.html

Improving the coverage

Coverage is generated from the autotest suite, unit tests and the example sketches.

Choose the most relevant of those three mechanisms to add new tests to. Generally:

• AP_Maths code should be done as unit tests

• flight code should be tested with the autotest suite

• sensor/external-device code can be tested by creating a simulator
