# tasty-process

`tasty-process` is a library for running integration tests with the [Tasty](https://github.com/UnkindPartition/tasty) testing framework.

Features:

- Run an external process as a test case

- Supply input to `stdin`

- Test the process' `exitcode`, `stdout` and `stderr`

- Set timeout for the running process using Tasty's `Timeout` option

- Automatic clean up the process after the test

## Example

Here is an example Echo program that reads from `stdin` and echos back to `stdout`.

```hs

module Main (main) where

main :: IO ()

main = getLine >>= putStr

```

And here is a test case for the Echo program using `tasty-process`.

```hs

import System.Exit (ExitCode (..))

import Test.Tasty (TestTree)

import Test.Tasty.Process

echoTest :: TestTree

echoTest =

  setTimeout (1000000) $ -- set timeout to 1 second

    processTest

      "Echo test" -- test name

      TestProcess

        { process =

          (proc "echo-test" []) -- process to launch with a list of arguments

        , input = "Echo!" -- input to stdin

        , exitCodeCheck = equals ExitSuccess -- check exit code

        , stdoutCheck = equals "Echo!" -- check stdout

        , stderrCheck = equals "" -- check stderr

        }

```
