This document discusses writing tests for CSS text and its derivations. It outlines CSS text properties like decorations, transforms, whitespace, and alignments. It also covers writing modes like bidirectional text and vertical flow. The document recommends creating test suites for properties as they progress through the W3C recommendation process, from Working Draft to Last Call to Candidate Recommendation to Proposed Recommendation. It provides a link to the CSS test suite manager where test suites are annotated in specifications.
