README

Formerly Yaml Tests

Yaml Tasks is a simple composer plugin that make it as simple as possible to define and run a set of commands using YML.

It provides a composer command and an executable script that simply reads a YML file and runs each line as a process.

In addition, it integrates with GitHub's Commit Status API. If GITHUB_TOKEN is specified, the status of each command will be posted back to GitHub.com, to be displayed on the pull request.

The output is rendered in a way to be easier to read, and proper exit code returns if a single process fails.

Get Started

  1. Add YamlTasks to your project.

     cd my-composer-project
     composer require devshop/yaml-tasks
    
  2. Create a tests.yml file that looks something like this:

     myproject/php/lint: find src -name '*.php' -print0 | xargs -0 -n1 php -l
     myproject/php/cs: 
       description: CodeSniffer
       command: bin/phpcs --standard=PSR2 -n  --colors
     myproject/debug/environment: |
       env
    
  3. Run the yaml-tasks composer command or the yaml-tasks bin script:

     composer yaml-tasks
     bin/yaml-tasks
    

    or

     composer y
    

Global Install

composer global require devshop/yaml-tasks

To confirm the command is installed, ask for help:

composer yaml-tests --help

Or run the bin/yaml-tasks command:

bin/yaml-tasks

GitHub Integration

If you pass yaml-tasks a GitHub Token, it will send the test results as "commit status" indicators.

There are 3 ways to pass the GitHub Token to YamlTasks:

  1. Use the --github-token command line option. Don't use this in CI, or you might expose your GitHub token in logs.

  2. Set a GITHUB_TOKEN environment variable. This is pretty simple in Docker, but can be a challenge if your tasks get run in different environments.

  3. Recommended: Create a .env file in your repo, or in your user's home directory:

    GITHUB_TOKEN=abcdefg
    

    There is a .env.example file in this directory you can use as an example.

Writing tasks

Create tasks.yml file

By default the composer yaml-tasks command looks for a tasks.yml file in the project root. You can also pass a path using the --tasks-file option.

The tasks.yml file is read as a simple collection of commands. The key can be any string, as long as it is unique in the test suite.

test/dir: pwd
test/environment: env

You can also include commands in a list:

lint:
  - find src -name '*.php' -print0 | xargs -0 -n1 php -l
  - find web/modules/custom -name '*.php' -print0 | xargs -0 -n1 php -l
  - find tasks/src -name '*.php' -print0 | xargs -0 -n1 php -l

You can include a description for each test like:

debug: 
  command: env
  description: Current Environment

Commands in tasks.yml

Yaml Tasks work like Composer Scripts: If your project has the config.bin-dir set in composer.json, Composer will automatically add that directory to the PATH when scripts or other commands are run.

For example, you can include PHPUnit and call it without specifying the full path in composer scripts or tasks.yml

composer.json:

{
    "config": {
        "bin-dir": "bin/"
    },
    "require": {
        "devshop/yaml-tasks": "^1.5",
        "phpunit/phpunit": "^8.1"
    },
    "scripts": {
        "test": [
            "which phpunit",
            "phpunit --version"
        ]
    }
}

Having the scripts.test section in composer.json creates a composer command called composer test.

tasks.yml:

test/debug: 
  - which phpunit
  - phpunit --version

If you want to only maintain one set of scripts, you can reference composer scripts in tasks.yml:

tasks.yml:

test/debug: composer test 

Running tasks

Once the tasks.yml file is in place, and the composer yaml-tasks command is available, you can trigger test runs.

Dry Runs vs Normal

This plugin was also designed to pass these tasks as "Commit Statuses" on GitHub. This allows us to tag the results to the specific commit, pass or fail.

If the environment variable GITHUB_TOKEN or the command line option --github-token is NOT set, the --dry-run option will be forced.

Use the --dry-run option if you have a token set but do not want to post test results to GitHub.

Run composer yaml-tasks or, just like all composer commands, you can use shortcuts like compose y.

composer yaml-tasks

The output will look something like this:

Test Run

And you will get a nice summary at the end like this:

Test Run

Yaml-Tasks executable

There is now a "bin" for yaml-tasks, allowing the command to be run by itself.

If you require devshop/yaml-tasks, you will see a symlink to yaml-tasks in your bin-dir.
