单元测试

junit 简单使用：

testcase：

testcase

@RunWith(Parameterized.class)
public class QuickTest extends TestCase {
    
    @Parameters
    public static Collection<Object[]> getParam(){
        return Arrays.asList(new Object[][]{
                {3,3},
                {5,5}
        });
    }
    private int input;
    private int expect;
    public QuickTest(int input,int expect){
        this.input = input;
        this.expect = expect;
    }
    @Test
    public void test() {
        assertEquals(input,expect);
    }

}

testsuite：

@RunWith(Suite.class)
@SuiteClasses({ QuickTest.class })
public class AllTests {
    public static Test suite(){
        TestSuite ts = new TestSuite("sort test");
        ts.addTestSuite(QuickTest.class);
        ts.addTestSuite(QuickTest.class);
        return ts;
    }
}
