README

🗄 Provides functionality to work with PDO, reset a database and load fixtures within Kahlan

Requirements

• PHP >= 7.0
• Kahlan ^3.0

Installation

composer require brunty/kahlan-pdo --dev

Setup

Folders:

1. Create a folder to store your database related files (/spec/db is suggested)
2. Create a folder to store your SQL files to load into the database (/spec/db/sql is suggested)
3. Within the folder where your database related files will be stored created a file reset.php which will be the file you'll use to reset your DB whenever you call the function to do so.
4. Within the folder where your database related files will be stored, created a fixtures folder
5. Create fixtures as you need for your tests in the fixtures folder.

Config:

In kahlan-config.php setup the path to your db folder and if you wish to use the \Brunty\Kahlan\PDO\sql() helper function, add the path to a directory that will hold SQL files as follows:

\Kahlan\box('db.path', __DIR__ . '/spec/db');
\Kahlan\box('db.path.sql', __DIR__ . '/spec/db/sql');

Usage

<?php

use function Brunty\Kahlan\PDO\reset;
use function Brunty\Kahlan\PDO\fixture;
use function Brunty\Kahlan\PDO\db;

describe('SqliteThingRepository', function() {

    beforeEach(function() {
        reset(); // reset our database before each test
    });

    it('gets all things from the database', function() {
        fixture('things'); // load fixtures inside this test

        // do stuff
        $stmt = db()->query('SELECT * FROM Things');
        $things = $stmt->fetchAll();
        // run assertions
    });
});

Using the \Brunty\Kahlan\PDO\reset() function without a parameter will create an in-memory database in SQLite, but you can pass the DSN, username and password to it and it'll use those instead.

With loading fixtures, you can then create a file within /spec/db/fixtures and call the name of that file (without the .php extension) to do whatever you might need to load data into the database.

For example:

\Brunty\Kahlan\PDO\load('things'); would load the file: /spec/db/fixtures/things.php into the database.

You could setup objects yourself with something like Faker or you could just load SQL into the database directly:

In /spec/db/fixtures/things.php:

<?php

\Brunty\Kahlan\PDO\sql('things');

The helper function \Brunty\Kahlan\PDO\db() returns the instance of PDO that is in the Kahlan box.

The helper function \Brunty\Kahlan\PDO\sql() loads SQL from the file given (in the \Kahlan\box('db.path.sql') directory, without the .sql extension) into the PDO instance in the Kahlan box.
