    <p>I am developing Unit tests for testing model functions.</p> <p>I am using PHP PDO with DBUnit 1.1.2 and PHPUnit 3.6.10 and my dataset is a yml file. </p> <p>I need to turn off foreign key checks while the fixtures are being loaded in the database. After that I need to turn it on again so that I can run my tests under those constraints.</p> <p>Below is a snippet (not the entire class file) of code in my generalized Testcase file which I will include for any new test case I develop.</p> <p>When I run a test case under these settings these settings i found that $pdo->exec() is not executing.</p> <p>What is wrong with my approach? Is there a better alternative?</p> <pre><code>class MyTestCase extends PHPUnit_Extensions_Database_TestCase { public function getConnection() { $this-&gt;pdo = $this-&gt;getPDO(); echo "BEFORE FOREIGN KEY QUERY\n"; $conn = $this-&gt;createDefaultDBConnection($this-&gt;pdo, 'my-schema'); $this-&gt;pdo-&gt;exec("set foreign_key_checks=0"); return $conn; } private function getPDO() { include BASEPATH . '/application/config/database.php'; $dbt = $db['testing']; $conn_string = sprintf("%s:host=%s;dbname=%s", $dbt['dbdriver'], $dbt['hostname'], $dbt['database']); $pdo = new PDO($conn_string, $dbt['username'], $dbt['password']); return $pdo; } public function getDataSet() { echo "BEFORE FOREIGN KEY QUERY in getDataSet\n"; $this-&gt;pdo-&gt;exec("set foreign_key_checks=1"); return new PHPUnit_Extensions_Database_DataSet_YamlDataSet(ROOTPATH."/application/tests/data/my-dataset.yml"); } public function setUp() { parent::setUp(); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
