Class

UserLoginTestCase

Functional tests for user logins, including rate limiting of login attempts.

Code

function testGlobalLoginFloodControl() {

  // Set the global login limit.
  variable_set('user_failed_login_ip_limit', 10);

  // Set a high per-user limit out so that it is not relevant in the test.
  variable_set('user_failed_login_user_limit', 4000);
  $user1 = $this
    ->drupalCreateUser(array());
  $incorrect_user1 = clone $user1;
  $incorrect_user1->pass_raw .= 'incorrect';

  // Try 2 failed logins.
  for ($i = 0; $i < 2; $i++) {
    $this
      ->assertFailedLogin($incorrect_user1);
  }

  // A successful login will not reset the IP-based flood control count.
  $this
    ->drupalLogin($user1);
  $this
    ->drupalLogout();

  // Try 8 more failed logins, they should not trigger the flood control
  // mechanism.
  for ($i = 0; $i < 8; $i++) {
    $this
      ->assertFailedLogin($incorrect_user1);
  }

  // The next login trial should result in an IP-based flood error message.
  $this
    ->assertFailedLogin($incorrect_user1, 'ip');

  // A login with the correct password should also result in a flood error
  // message.
  $this
    ->assertFailedLogin($user1, 'ip');
