Namespace

Code

protected function transactionInnerLayer(string $suffix) : void {
    $depth = $this->connection
        ->transactionManager()
        ->stackDepth();
    // Start a transaction. If we're being called from ->transactionOuterLayer,
    // then we're already in a transaction. Normally, that would make starting
    // a transaction here dangerous, but the database API handles this problem
    // for us by tracking the nesting and avoiding the danger.
    $txn = $this->connection
        ->startTransaction();
    $depth2 = $this->connection
        ->transactionManager()
        ->stackDepth();
    $this->assertSame($depth + 1, $depth2, 'Transaction depth has increased with new transaction.');
    // Insert a single row into the testing table.
    $this->connection
        ->insert('test')
        ->fields([
        'name' => 'Daniel' . $suffix,
        'age' => '19',

    $this->assertTrue($this->connection
        ->inTransaction(), 'In transaction inside nested transaction.');
