A test case defines the fixture to run multiple tests. To define a test case
TestCase
setUp()
tearDown()
.public class MathTest extends TestCase { protected double fValue1; protected double fValue2; protected void setUp() { fValue1= 2.0; fValue2= 3.0; } }For each test implement a method which interacts with the fixture. Verify the expected results with assertions specified by calling
assertTrue(String, boolean)
with a boolean.
public void testAdd() { double result= fValue1 + fValue2; assertTrue(result == 5.0); }Once the methods are defined you can run them. The framework supports both a static type safe and more dynamic way to run a test. In the static way you override the runTest method and define the method to be invoked. A convenient way to do so is with an anonymous inner class.
TestCase test= new MathTest("add") { public void runTest() { testAdd(); } }; test.run();The dynamic way uses reflection to implement
runTest()
. It dynamically finds
and invokes a method.
In this case the name of the test case has to correspond to the test method
to be run.
TestCase test= new MathTest("testAdd"); test.run();The tests to be run can be collected into a TestSuite. JUnit provides different test runners which can run a test suite and collect the results. A test runner either expects a static method
suite
as the entry
point to get a test to run or it will extract the suite automatically.
public static Test suite() { suite.addTest(new MathTest("testAdd")); suite.addTest(new MathTest("testDivideByZero")); return suite; }
