Version Compatibility

Laravel | Testbench :---------|:---------- 5.0.x | 3.0.x 5.1.x | 3.1.x 5.2.x | 3.2.x 5.3.x | 3.3.x 5.4.x | 3.4.x 5.5.x | 3.5.x 5.6.x | 3.6.x 5.7.x | 3.7.x 5.8.x | 3.8.x 6.x | 4.x

Getting Started

Before going through the rest of this documentation, please take some time to read the Package Development section of Laravel's own documentation, if you haven't done so yet.

Installation

To install through composer, simply put the following in your composer.json file:

{
    "require-dev": {
        "orchestra/testbench": "^4.0"
    }
}

And then run composer install from the terminal.

Quick Installation

Above installation can also be simplify by using the following command:

composer require --dev "orchestra/testbench=^4.0"

Usage

To use Testbench Component, all you need to do is extend Orchestra\Testbench\TestCase instead of PHPUnit\Framework\TestCase. The fixture app booted by Orchestra\Testbench\TestCase is predefined to follow the base application skeleton of Laravel 6.

<?php

class TestCase extends Orchestra\Testbench\TestCase
{
    //
}

Custom Service Provider

To load your package service provider, override the getPackageProviders.

protected function getPackageProviders($app)
{
    return ['Acme\AcmeServiceProvider'];
}

Custom Aliases

To load your package alias, override the getPackageAliases.

protected function getPackageAliases($app)
{
    return [
        'Acme' => 'Acme\Facade'
    ];
}

Overriding setUp() method

Since Orchestra\Testbench\TestCase replace Laravel's Illuminate\Foundation\Testing\TestCase, if you need your own setUp() implementation, do not forget to call parent::setUp():

/**
 * Setup the test environment.
 */
protected function setUp()
{
    parent::setUp();

    // Your code here
}

If you need to add something early in the application bootstrapping process, you could use the getEnvironmentSetUp() method:

/**
 * Define environment setup.
 *
 * @param  \Illuminate\Foundation\Application  $app
 * @return void
 */
protected function getEnvironmentSetUp($app)
{
    // Setup default database to use sqlite :memory:
    $app['config']->set('database.default', 'testbench');
    $app['config']->set('database.connections.testbench', [
        'driver'   => 'sqlite',
        'database' => ':memory:',
        'prefix'   => '',
    ]);
}

To reduce setup configuration, you could use testing database connection (:memory: with sqlite driver) via setting it up under getEnvironmentSetUp() or by defining it under PHPUnit Configuration File:

<phpunit>

    // ...

    <php>
        <env name="DB_CONNECTION" value="testing"/>
    </php>

</phpunit>

Overriding Console Kernel

You can easily swap Console Kernel for application bootstrap by overriding resolveApplicationConsoleKernel() method:

/**
 * Resolve application Console Kernel implementation.
 *
 * @param  \Illuminate\Foundation\Application  $app
 * @return void
 */
protected function resolveApplicationConsoleKernel($app)
{
    $app->singleton('Illuminate\Contracts\Console\Kernel', 'Acme\Testbench\Console\Kernel');
}

Overriding HTTP Kernel

You can easily swap HTTP Kernel for application bootstrap by overriding resolveApplicationHttpKernel() method:

/**
 * Resolve application HTTP Kernel implementation.
 *
 * @param  \Illuminate\Foundation\Application  $app
 * @return void
 */
protected function resolveApplicationHttpKernel($app)
{
    $app->singleton('Illuminate\Contracts\Http\Kernel', 'Acme\Testbench\Http\Kernel');
}

Overriding Application Timezone

You can also easily override application default timezone, instead of the default "UTC":

/**
 * Get application timezone.
 *
 * @param  \Illuminate\Foundation\Application  $app
 * @return string|null
 */
protected function getApplicationTimezone($app)
{
    return 'Asia/Kuala_Lumpur';
}

Using Migrations

Package developer should be using ServiceProvider::loadMigrationsFrom() feature to automatically handle migrations for packages.

$this->artisan('migrate', ['--database' => 'testbench'])->run();

Using Laravel Migrations

By default Testbench doesn't execute the default Laravel migrations which include users and password_resets table. In order to run the migration just add the following command:

$this->loadLaravelMigrations();

You can also set specific database connection to be used by adding --database options:

$this->loadLaravelMigrations(['--database' => 'testbench']);

Running Testing Migrations

To run migrations that are only used for testing purposes and not part of your package, add the following to your base test class:

/**
 * Setup the test environment.
 */
protected function setUp()
{
    parent::setUp();

    $this->loadMigrationsFrom(__DIR__ . '/database/migrations');
    
    // and other test setup steps you need to perform
}

Notes and Considerations

• Your migration files has to suite Laravel's convention, e.g. 0000_00_00_000000_create_package_test_tables.php.
• You may choose to put your migrations folder in tests/database/.
• You may choose to change your test-migrations class name to be different from the published class names, e.g. from CreateUsersTable to CreateUsersTestTable or otherwise you may encounter composer class loader collision.

Using Model Factories

Testbench include withFactories() method to allow you to register custom model factory path for your test suite.

$this->withFactories(__DIR__.'/factories');

Example

To see a working example of testbench including how to set your configuration, check the file:

• Testing with Database.

Alternative Testing

There also 3rd party packages that extends Testbench:

• Testbench with Laravel Dusk
• Testbench with BrowserKit
• Testbench with CodeCeption
• Testbench with PHPSpec

Troubleshoot

No supported encrypter found. The cipher and / or key length are invalid.

RuntimeException: No supported encrypter found. The cipher and / or key length are invalid.

This error would only occur if your test suite require usages of the encrypter. To solve this you can add a dummy APP_KEY or use a specific key to your application/package phpunit.xml.

<phpunit>

    // ...

    <php>
        <env name="APP_KEY" value="AckfSECXIvnK5r28GVIWUAxmbBSjTsmF"/>
    </php>

</phpunit>

Why Testbench doesn't include any of the App classes.

The reason Testbench remove all the classes is to make sure that you would never depends on it when developing Laravel Packages. Classes such as App\Http\Controllers\Controller and App\User are simple to be added but the problems with these classes is that it can be either:

• Removed, moved to other location such as App\Models\User, or
• Renamed using php artisan app:name Acme which would rename App\User to Acme\User.

Missing Browser Kit support after testing on Laravel 5.4

Replace orchestra/testbench with orchestra/testbench-browser-kit and follow the installation guide.
