WPQueries
This module should be used in integration tests, see levels of testing for more information, to make assertions on the database queries made by the global $wpdb object. This module requires the WPLoader module to work. The module will set, if not set already, the SAVEQUERIES constant to true and will throw an exception if the contstant is already set to a falsy value.

Configuration

This module does not require any configuration, but requires the WPLoader module to work correctly.

Usage

This module must be used in a test case extending the \Codeception\TestCase\WPTestCase class.
The module public API is accessible calling via the \Codeception\TestCase\WPTestCase::queries() method:
1
<?php
2
​
3
use Codeception\Module\WPQueries;
4
​
5
class WPQueriesUsageTest extends \Codeception\TestCase\WPTestCase
6
{

public function test_queries_made_by_factory_are_not_tracked()
8
{
9
$currentQueriesCount = $this->queries()->countQueries();
10
​
11
$this->assertNotEmpty($currentQueriesCount);
12
​
13
static::factory()->post->create_many(3);
14
​
15
$this->assertNotEmpty($currentQueriesCount);
16
$this->assertEquals($currentQueriesCount, $this->queries()->countQueries());
17
}

public function test_count_queries()
20
{
21
$currentQueriesCount = $this->queries()->countQueries();
22
​

$this->assertNotEmpty($currentQueriesCount);
24
​
25
foreach (range(1, 3) as $i) {
26
wp_insert_post(['post_title' => 'Post ' . $i, 'post_content' => str_repeat('test', $i)]);
27
}
28
