Code

public function testNestedConditions() : void {
    // This query should translate to:
    // "SELECT job FROM {test} WHERE name = 'Paul' AND (age = 26 OR age = 27)"
    // That should find only one record. Yes it's a non-optimal way of writing
    // that query but that's not the point!
    $query = $this->connection
        ->select('test');
    $query->addField('test', 'job');
    $query->condition('name', 'Paul');
    $query->condition($this->connection
        ->condition('OR')
        ->condition('age', 26)
        ->condition('age', 27));
    $job = $query->execute()
        ->fetchField();
    $this->assertEquals('Songwriter', $job, 'Correct data retrieved.');
