README
A custom assertion for phpunit that allows you to count the number of SQL queries used in a test. Can be used to enforce certain performance characteristics (ie: limit queries to X for a certain action).
This works for Laravel only at the moment.
Installation
You can install the package via composer:
composer require --dev mattiasgeniar/phpunit-query-count-assertions
Usage
Add the AssertsQueryCounts
trait to your test-class, initialize it in the setup()
and you can start asserting queries.
use Mattiasgeniar\PhpunitQueryCountAssertions\AssertsQueryCounts; class YourTest extends TestCase { use AssertsQueryCounts; public function setUp(): void { parent::setUp(); AssertsQueryCounts::trackQueries(); } /** @test */ public function your_tests_go_here() { $this->assertNoQueriesExecuted(); } }
Available assertions/methods
You can use the following methods, their names should be self-explanatory:
$this->assertNoQueriesExecuted(); // No queries should have been run $this->assertQueryCountMatches(5); // Query count should be exactly 5 $this->assertQueryCountLessThan(6); // Should be less than 6 queries $this->assertQueryCountGreaterThan(4); // Should be more than 4 queries
All these methods can accept a closure as an extra argument. The assertion will only take in account the queries performed inside the closure. If you use this way of testing, you don't need to call trackQueries
yourself.
$this->assertQueryCountMatches(2, function() { // assertion will pass if exactly 2 queries happen here. });
Testing
composer test
