# shout
|
|
|
|
Transcript-based shell integration test runner. Bun + TypeScript.
|
|
|
|
## Commands
|
|
|
|
- `bun test` — run unit tests
|
|
- `bunx tsc --noEmit` — type check
|
|
- `bun run src/cli/index.ts test [files...]` — run shout CLI
|
|
|
|
## Architecture
|
|
|
|
- `src/parse.ts` — parses `.shout` files into `ShoutFile` (list of `Command`)
|
|
- `src/run.ts` — executes commands via `Bun.spawn(["/bin/sh"])`, captures output with sentinels
|
|
- `src/match.ts` — wildcard-aware output matching and diff generation
|
|
- `src/format.ts` — evaluates pass/fail, formats failures and summary
|
|
- `src/update.ts` — rewrites `.shout` files with actual output (`--update` mode)
|
|
- `src/duration.ts` — parses duration strings (`10s`, `500ms`, `1m`)
|
|
- `src/cli/index.ts` — CLI entry point via `commander`
|
|
- `src/index.ts` — barrel exports
|
|
|
|
## .shout file format
|
|
|
|
- `$ ` prefix = command to execute
|
|
- Lines between commands = expected output (stdout+stderr merged)
|
|
- `...` on its own line = multi-line wildcard (matches zero or more lines)
|
|
- `...` inline = matches any characters on that line
|
|
- `[N]` on last line of expected output = assert exit code N
|
|
- `[*]` = assert any non-zero exit code; default expects 0
|
|
- `#` after a command = comment (stripped); `#` in expected output is literal
|
|
- Each file runs in a fresh temp dir with a single `/bin/sh` session
|
|
|
|
## Style
|
|
|
|
- Strict TypeScript, Bun runtime
|
|
- No classes — plain functions and types
|
|
- Tests in `src/*.test.ts`, example `.shout` files in `test/`
