function CommonSizeTestCase::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.

Overrides DrupalUnitTestCase::setUp

File

modules/simpletest/tests/common.test, line 553

Tests for common.inc functionality.

Class

CommonSizeTestCase

Tests file size parsing and formatting functions.

Code
