Test case for Drupal unit tests.

These tests can not access the database nor files. Calling any Drupal function that needs the database will throw exceptions. These include watchdog(), module_implements(), module_invoke_all() etc.



DrupalTestCase::$assertionsAssertions thrown in that test case.
DrupalTestCase::$databasePrefixThe database prefix of this test run.
DrupalTestCase::$originalFileDirectoryThe original file directory, before it was changed for testing purposes.
DrupalTestCase::$resultsCurrent results of this test case.
DrupalTestCase::$skipClassesThis class is skipped when looking for the source of an assertion.
DrupalTestCase::$testIdThe test run ID.
DrupalTestCase::$timeLimitTime limit for the test.

Functions & methods

DrupalTestCase::assertInternal helper: stores the assert.
DrupalTestCase::assertEqualCheck to see if two values are equal.
DrupalTestCase::assertFalseCheck to see if a value is false (an empty string, 0, NULL, or FALSE).
DrupalTestCase::assertIdenticalCheck to see if two values are identical.
DrupalTestCase::assertNotEqualCheck to see if two values are not equal.
DrupalTestCase::assertNotIdenticalCheck to see if two values are not identical.
DrupalTestCase::assertNotNullCheck to see if a value is not NULL.
DrupalTestCase::assertNullCheck to see if a value is NULL.
DrupalTestCase::assertTrueCheck to see if a value is not false (not an empty string, 0, NULL, or FALSE).
DrupalTestCase::deleteAssertDelete an assertion record by message ID.
DrupalTestCase::errorFire an error assertion.
DrupalTestCase::errorHandlerHandle errors during test runs.
DrupalTestCase::exceptionHandlerHandle exceptions.
DrupalTestCase::failFire an assertion that is always negative.
DrupalTestCase::generatePermutationsConverts a list of possible parameters into a stack of permutations.
DrupalTestCase::getAssertionCallCycles through backtrace until the first non-assertion method is found.
DrupalTestCase::insertAssertStore an assertion from outside the testing context.
DrupalTestCase::passFire an assertion that is always positive.
DrupalTestCase::randomNameGenerates a random string containing letters and numbers.
DrupalTestCase::randomStringGenerates a random string of ASCII characters of codes 32 to 126.
DrupalTestCase::runRun all tests in this class.
