function WebTestBase::setUp

Sets up a Drupal site for running functional and integration tests.

Installs Drupal with the installation profile specified in \Drupal\simpletest\WebTestBase::$profile into the prefixed database.

Afterwards, installs any additional modules specified in the static \Drupal\simpletest\WebTestBase::$modules property of each class in the class hierarchy.

After installation all caches are flushed and several configuration values are reset to the values of the parent site executing the test, since the default values may be incompatible with the environment in which tests are being executed.

    // from setup to setup. The Australia/Sydney time zone is chosen so all
    // tests are run using an edge case scenario (UTC+10 and DST). This choice
    // is made to prevent time zone related regressions and reduce the
    // fragility of the testing system in general. This is also set in config in
