Wye

Build Status Latest Stable Version Total Downloads License

A library that makes unit testing database-driven code in PHP a breeze. Mock the native PDO class, define query results, and inspect executed statements.

"[In firefighting a] hose appliance used for splitting one line into two discharges. Often a gated wye is used to allow and disallow water flow through the two separate discharges." - https://en.wikipedia.org/wiki/Glossary_of_firefighting_equipment#Wye

Installation

Wye is registered with Packagist and can be installed with Composer. Run the following on the command line:

composer require --dev stratedge/wye

Once Wye has been included in your project, just make sure to require Composer's autoloader:

require_once 'vendor/autoload.php';

Basic Usage Example

use Stratedge\Wye\Wye;

//In test setup
//-------------

//Reset the Wye to its clean state
Wye::reset()

//Create a Wye PDO object
$pdo = Wye::makePDO();

//Inject PDO into database layer
Database::setConnection($pdo);

//In test
//-------

//Create a Result object
$result = Wye::makeResult();

//Add a row or two to return
$result->addRow(['type' => 'Pumper', 'apparatus' => 'Engine 1']);

//Attach Result to Wye to be served when a query is executed
$result->attach();

//Run code to test
$class_to_test->doSomething();

//Inspect execution
$stmt = Wye::getStatementAtIndex(0);
$this->assertStringStartsWith('SELECT', $stmt->getStatement());
$this->assertCount(2, count($stmt->getBindings());
$this->assertSame('id', $stmt->getBindings()->first()->getParameter());
$this->assertSame(1, Wye::getNumQueries());
//and more!

WAIT, THERE'S MORE
