spring-boot-单元测试参数数

简单案例

@RunWith(Parameterized.class)
public class ParameterTest {
    // 2.声明变量存放预期值和测试数据
    private String firstName;
    private String lastName;

    //3.声明一个返回值 为Collection的公共静态方法，并使用@Parameters进行修饰
    @Parameterized.Parameters
    public static List<Object[]> param() {
        // 这里我给出两个测试用例
        return Arrays.asList(new Object[][]{{"Mike", "Black"}, {"Cilcln", "Smith"}});
    }

    //4.为测试类声明一个带有参数的公共构造函数，并在其中为之声明变量赋值
    public ParameterTest(String firstName, String lastName) {
        this.firstName = firstName;
        this.lastName = lastName;
    }

    // 5. 进行测试，发现它会将所有的测试用例测试一遍
    @Test
    public void test() {
        String name = firstName + " " + lastName;
        System.out.println(name);
        assertThat("Mike Black", is(name));
    }


}

参数化在 测试controller 中的应用

@RunWith(Parameterized.class)
@SpringBootTest
public class LearnController14Test {

    @Autowired
    private WebApplicationContext wac;

    private MockMvc mvc;

    private MockHttpSession session;


    public Long id;
    public String title;

    public LearnController14Test(Long id, String title) {
        super();
        this.id = id;
        this.title = title;
    }

    /**
     * 这些参数，都会测试一遍
     *
     * @return
     */
    @Parameterized.Parameters
    public static List<Object[]> data() {
        return Arrays.asList(new Object[][]{{999L, "Black"}, {997L, "Smith"}});
    }


    @Before
    public void setupMockMvc() throws Exception {
        //借助TestContextManager来实现上下文注入
        TestContextManager testContextManager = new TestContextManager(getClass());
        testContextManager.prepareTestInstance(this);


        //初始化MockMvc对象
        mvc = MockMvcBuilders.webAppContextSetup(wac).build();

        //构建session
        session = new MockHttpSession();
        User user = new User("root", "root");
        //拦截器那边会判断用户是否登录，所以这里注入一个用户
        session.setAttribute("user", user);
    }


    /**
     * 获取教程测试用例
     * <p>
     * get 请求
     *
     * @throws Exception
     */
    @Test
    public void qryLearn() throws Exception {

        mvc.perform(MockMvcRequestBuilders.get("/learn/resource/" + id + "?title=" + title)
                .contentType(MediaType.APPLICATION_JSON_UTF8)
                .accept(MediaType.APPLICATION_JSON_UTF8)
                .session(session)
        )
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andDo(MockMvcResultHandlers.print());
    }
