shout

shout is kinda like really basic integration testing for your cli.

Write .shout files that look like shell sessions and run shout to test 'em.

Install

git clone https://git.nose.space/defunkt/go-shout
cd go-shout
make install

Features

Everything you could ever ask for:

$ echo hello
hello

$ brew --version
Homebrew 5...

$ ls missing
ls: missing: No such file or directory
[1]

... matches anything — a whole line inline, or any number of lines on its own.

[1] after the expected output matches the exit code.

Usage

$ shout test
...............
15 passed in 23ms

shout test runs code in a temp directory. -k/--keep keeps it around.

--update will modify .shout files to match reality, without running any tests.

Each line in a .shout file is run sequentially, unless --parallel is passed.

Usage: shout test [options] [files...]

Run .shout test files

Arguments:
  files            Files or directories to test

  -u, --update     Rewrite expected output in-place with actual output

  --clean-env      Start with empty environment
  --path <path>    Prepend <path> to PATH (repeatable)
  --timeout <dur>  Per-command timeout (default: "10s")
  -v, --verbose    Print each command as it runs
