AssertChain

Build Status

AssertChain is PHPUnit helper. It enables you to write PHPUnit assert with method chain.

Setup

Install AssertChain by composer.

composer require --dev gong023/assert_chain:dev-master
# install phpunit if you do not install yet.
# composer require --dev phpunit/phpunit:4.*

Import AssertChain trait to your test class.

class YourTestClass extends \PHPUnit_Framework_TestCase
{
    use AssertChain\AssertChain;
}

Usage

First you call assert, and keep asserting as you like.

You can use all assertions in PHPUnit_Framework_Assert.

public function testWithArray()
{
    $arr = [
        'intKey'    => 1,
        'stringKey' => 'foo',
        'boolKey'   => true,
    ];

    $this->assert()
      ->notEmpty($arr)
      ->arrayHasKey('intKey', $arr)
      ->same(1, $arr['intKey'])
      ->arrayHasKey('stringKey', $arr)
      ->same('foo', $arr['stringKey'])
      ->arrayHasKey('boolKey', $arr)
      ->true($arr['boolKey']);

    /*
     * above code is equal to this.
     *
     * $this->assertNotEmpty($arr);
     * $this->assertArrayHasKey('intKey', $arr);
     * $this->assertSame(1, $arr['intKey']);
     * $this->assertArrayHasKey('stringKey', $arr);
     * $this->assertSame('foo', $arr['stringKey']);
     * $this->assertArrayHasKey('boolKey', $arr);
     * $this->assertTrue($arr['boolKey']);
     */
}

If you are sick of writing $actual value too many times, you can use centralizedAssert.

public function testWithArray()
{
    $arr = ['key' => 'value'];

    $this->centralizedAssert($arr)
      ->notNull()
      ->notEmpty()
      ->notCount(0)
      ->count(1)
      ->arrayNotHasKey('no existing key')
      ->arrayHasKey('key')
      ->notContains('no existing value')
      ->contains('value')
      ->equals(['key' => 'value']);

    /*
     * above code is equal to this.
     *
     * $this->assertNotNull($arr);
     * $this->assertNotEmpty($arr);
     * $this->assertNotCount(0, $arr);
     * $this->assertCount(1, $arr);
     * $this->assertArrayNotHasKey('no existing key', $arr);
     * $this->assertNotContains('no existing value', $arr);
     * $this->assertContains('value', $arr);
     * $this->assertEquals(['key' => 'value']);
     */
}

centralizedAssert automatically sets $actual value to every assertions in PHPUnit_Framework_Assert.

You need not type $actual value too many times.

If you want to get more idea with centralizedAssert, AssertChain test class will help you.

IDE friendly

AssertChain is IDE friendly. You can get method autocomplete.
