+# Test Structure
+
+## Specifications
+
+`mustache_test.dart` and `mustache_specs.dart` generate tests for all mustache specifications,
+except for those disabled by `mustache_test.dart`'s `unsupportedSpecs` constant.
+`dart test mustache_test.dart` runs all of the generated tests.
+
+Each generated specification file contains the mustache commit hash from which it was generated,
+and the date when it was generated.
+
+### Updating specifications
+
+From the package root, run `dart run tool/download_spec.dart` to pull new definitions from the
+mustache repository into `test/specs/`.
+
+## Features
+
+Standalone or handwritten tests regarding template output go in `feature_test.dart`.
+
+## Parser
+
+Tests for the template language parser go in `parser_test.dart`.
