Testing

The library's tests

The suite tests/Unit tests the texts and their languages, the addresses, the feedback contact, the enforcement procedure, the evaluation, the non-conformities, the versions of WCAG and the criteria each target measures, the status derived, every refusal of a statement, the plain data written and read back with every refusal of the reader, the reports read back, and the next version generated from an audit.

From the monorepo root:

vendor/bin/phpunit packages/accessibility-statement/tests

The library is held to 100 % covered mutation score by Infection.

Fuzzing

Two fuzz targets give the readers inputs nobody wrote, from the seeds of tests/Fuzz/corpus/:

• statement-reader: whatever StatementReader::fromJson() reads, it returns a statement that writes back to the data it reads again, or refuses the input with an InvalidStatement, and never throws anything else nor warns;
• report-reader: whatever ReportReader::fromJson() reads, it returns a report that serializes to JSON, or refuses the input with an InvalidReport.

composer fuzz -- statement-reader report-reader

Testing with the library

A statement is a value: build one in a test, or read one from an array, and compare toArray(). A generator test needs no checker either: an AuditResult of Reports built from Findings gives the findings wanted.
