function ConnectionUnitTest::setUp in Drupal 7

Sets up unit test environment.

Unlike DrupalWebTestCase::setUp(), DrupalUnitTestCase::setUp() does not install modules because tests are performed without accessing the database. Any required files must be explicitly included by the child class setUp() method.

ConnectionUnitTest

Tests management of database connections.

  // methods will not be executed.

    // as failure.

  // and closed in this test.
