Spring boot 如何创建未发现异常的单元测试？

这里我有一个测试来测试控制器，我成功地测试了create和findByName，我想用findByName\u notFound添加测试，但我还不明白怎么做

这是我的代码：

@Test
public void shouldRegisterNewStudent() throws Exception {
    Student student = new Student();
    student.setId(1);
    student.setParentsName("farizan");
    student.setParentsMobile("8465");
    student.setName("sahru");
    student.setClassroom(null);
    student.setNote("free text");
    Mockito.when(studentService.save(student)).thenReturn(student);

    mockMvc.perform(post("/register")
            .contentType("application/json")
            .content(objectMapper.writeValueAsString(student)))
            .andExpect(status().isCreated());
}
@Test
public void findStudentByName()throws Exception{
    Student student = new Student();
    student.setId(1);
    student.setParentsName("farizan");
    student.setParentsMobile("8465");
    student.setName("sahru");
    student.setClassroom(null);
    student.setNote("free text");
    final String name = "sahru";
    given(studentService.findByName("sahru")).willReturn(student);
    mockMvc.perform(get("/findByName/{name}",name)
            .contentType("application/json")
            .content(objectMapper.writeValueAsString(student)))
            .andExpect(status().isOk());
}
@Test
public void findStudentByName_notFound()throws Exception{
    final String name = "sahru";
    given(studentService.findByName("sarah")).willReturn((Student) Collections.emptyList());
    mockMvc.perform(get("/findByName/{name}",name)
            .contentType("application/json"))
            .andExpect(status().isNotFound());
}

}

这是一个教程，您可以使用

rest assured

库来测试rest API，它易于使用且功能强大

步骤：

在构建工具中包含依赖项，类似maven：

这不是答案；相反，最好是作为OP问题的评论。

     <dependency>
        <groupId>io.rest-assured</groupId>
        <artifactId>rest-assured</artifactId>
        <version>3.0.5</version>
        <scope>test</scope>
    </dependency>

@LocalServerPort
private int port;

@Test
public void test() {
    RestAssured.given()
            .port(port)
            .get("/test/api") //your endpoint
            .then()
            .assertThat()
            .statusCode(HttpStatus.NOT_FOUND.value());
 }
}
