DrupalWebTestCase::resetAllReset all data structures after having enabled new modules.
DrupalWebTestCase::setUpGenerates a random database prefix, runs the install scripts on the prefixed database and enable the specified modules. After installation many caches are flushed and the internal browser is setup so that the page requests will run on the new prefix.…
