# 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
=== RUN TestLexers
=== RUN TestLexers/C#
=== RUN TestLexers/CSS
--- PASS: TestLexers (0.01s)
--- PASS: TestLexers/C# (0.00s)
--- PASS: TestLexers/CSS (0.00s)
PASS
