| + | |||
| + | ===== Original Description ===== | ||
| + | |||
| + | "Class is a JUnit TestCase and implements the setUp method. The setUp method should call super.setUp(), but doesn't." -- 2014-01-30 | ||
| + | |||
| + | ===== Detailed Description ===== | ||
| + | |||
| + | In JUnit 3 in every class that inherits from TestCase the developer has to define a setup method where preparations for the test runs are located. In order to assure correct execution, the super method of the setup method has to be called within. | ||
| + | |||
| + | <note warning> | ||
| + | This bug applies to the version 3 of the JUnit library, which is not the current one anymore. | ||
| + | </note> | ||
| + | |||
| + | |||
| + | ===== Sample Problem Scenario ===== | ||
| + | <code Java> | ||
| + | protected void setUp() throws Exception { | ||
| + | //Comment | ||
| + | System.out.println("Setting up test"); | ||
| + | doSomePreparations(); | ||
| + | |||
| + | } | ||
| + | </Code> | ||
| + | |||
| + | ===== Sample Fix ===== | ||
| + | |||
| + | <code Java> | ||
| + | protected void setUp() throws Exception { | ||
| + | super.setup(); | ||
| + | //Comment | ||
| + | System.out.println("Setting up test"); | ||
| + | doSomePreparations(); | ||
| + | | ||
| + | } | ||
| + | </Code> | ||
