AssertChain is PHPUnit helper. It enables you to write PHPUnit assert with method chain.
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;
}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.
AssertChain is IDE friendly. You can get method autocomplete.
