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 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 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

*

* 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());

}

}
