Pest X-Args Plugin

This repository contains the Pest X-Args Plugin.

This plugin add to Pest the functionality to accept --x- arguments and access them from the test cases.

If you want to start testing your application with Pest, visit the main Pest Repository.

Installation

Install the plugin with Composer ».

composer require tembra/pest-plugin-x-args --dev

Versioning

This plugin is using Semantic Versioning »

• Major versions will always be the same as Pest
  • v2.x works with Pest v2.x

Usage

Run Pest with any --x- argument you want to be available to test cases.

vendor/bin/pest --x-username=random --x-password=secret

If using a Composer script don't forget to use --, the special argument operator, after script name.

composer test-script-name -- --x-username=random --x-password=secret

In you test cases use the hasXArg() and getXArg() functions.

use function Tembra\Pest\Plugins\XArgs\{hasXArg};
use function Tembra\Pest\Plugins\XArgs\{getXArg};

it('has --x-username and --x-password argument', function () {
    $hasUsername = hasXArg('username');
    $hasPassword = hasXArg('password');

    expect($hasUsername)->toBe(true)
        ->and($hasPassword)->toBe(true);
});

it('can login with valid credentials', function () {
    $username = getXArg('username');
    $password = getXArg('password');

    if (null === $username || null === $password) {
        $this->fail('You need to send valid username/password through command line.');
    }

    // try to login with $username and $password
    // and make expectations and/or assertions with result
});

About arguments

The arguments are firstly processed by Pest through Symfony\Component\Console\Input\Input and then sent to this and others plugins. So everything that works there should work here.

Right away this plugin identifies the --x- argument and then the first equal sign (=) to break the argument in two parts. Then it removes the --x- from the first part.

Some statements:

• Arguments have a key and a value.
• In argument --x-test=true the key is test and the value is true.
• Both key and value are always of type string.
• Arguments may have only a key like --x-active. When this is the case the value is an empty string.
• Arguments key are case insensitive.
• Arguments key can not have an equal sign (=).
• Arguments key may use special chars if properly escaped, except the equal sign (=).
• Arguments with the same key overwrites each other. The last remains.
• Arguments without a key are not made available (e.g. --x-=value).
• Arguments value may be between quotes (e.g. --x-key="complex value").
• Arguments value may use special chars if properly escaped.
• Unavailable arguments return false on hasXArg() and null on getXArg() calls.

To check some crazy usages you may look at tests/PluginTest.php and even run it with Pest 🚀.

Motivation

Necessity to access specific and sensitive values (like a password) on test cases without the use of environment variables or files at all to do not take the risk to commit them to a local or remote code repository, even knowing that we could add these files to .gitignore.
