org.junit.runners Class Parameterized

java.lang.Object
  org.junit.runner.Runner
      org.junit.runners.ParentRunner<Runner>
          org.junit.runners.Suite
              org.junit.runners.Parameterized

所有已实现接口:: Describable, Filterable, Sortable

public class Parameterized
extends Suite

The custom runner Parameterized implements parameterized tests. When running a parameterized test class, instances are created for the cross-product of the test methods and the test data elements.

For example, to test a Fibonacci function, write:

 @RunWith(Parameterized.class)
 public class FibonacciTest {
        @Parameters
        public static List<Object[]> data() {
                return Arrays.asList(new Object[][] {
                                Fibonacci,
                                { { 0, 0 }, { 1, 1 }, { 2, 1 }, { 3, 2 }, { 4, 3 }, { 5, 5 },
                                                { 6, 8 } } });
        }
 
        private int fInput;
 
        private int fExpected;
 
        public FibonacciTest(int input, int expected) {
                fInput= input;
                fExpected= expected;
        }
 
        @Test
        public void test() {
                assertEquals(fExpected, Fibonacci.compute(fInput));
        }
 }

Each instance of FibonacciTest will be constructed using the two-argument constructor and the data values in the @Parameters method.
