top down +can use whole program testcases +earlier demo -complicated stubs -stubs needed -testing stubs not real modules bottom up +no stub needed +test component for reuse +real test data -error found late -drivers need to be made suggested: bottom up if you need a module, you should write the test for that give stubs to those that need your stub JUnitOne of the most useful testing facilities - can handle white box testing as well as black box EclEmmaOne of the best tools, code coverage analysis JUnit in EclipseMake a new source folder, name it test Right click on the class you want to test: New -> JUnit Test Case
Choose the source folder the test folder Click Next, Choose the methods you want to test Finish
In the created test class right click, Run As -> JUnit Test
To test the method you can use methods like assertTrue(a.hasA()); or other assert.... method series.
To test methods that use System.inString data = "Hello, World!\r\n"; InputStream stdin = System.in; try { System.setIn(new ByteArrayInputStream(data.getBytes())); Scanner scanner = new Scanner(System.in); System.out.println(scanner.nextLine()); } finally { System.setIn(stdin); }
