+# Lexer tests
+
+This directory contains input source and expected output lexer tokens.
+
+Input filenames for lexers are in the form `<name>.actual`. Expected output filenames are in the form `<name>.expected`.
+
+Each input filename is parsed by the corresponding lexer and checked against the expected JSON-encoded token list.
+
+
+To add/update tests do the following:
+
+1. `export LEXER=csharp`
+1. Create/edit a file `lexers/testdata/${LEXER}.actual` (eg. `csharp.actual`).
+2. Run `go run ./cmd/chroma/main.go --lexer ${LEXER} --json lexers/testdata/${LEXER}.actual > lexers/testdata/${LEXER}.expected`.
+3. Run `go test -v -run TestLexers ./lexers`.
+
+
+eg.
+
+```bash
+$ export LEXER=csharp
+$ go run ./cmd/chroma/main.go --lexer ${LEXER} --json lexers/testdata/${LEXER}.${LEXER} > lexers/testdata/${LEXER}.expected
+$ go test -v -run TestLexers ./lexers
