spring boot:為service類做參數化單元測試(spring boot 2.4.3)

一，演示項目的相關信息

2,功能說明：演示給一個service生成測試文件

3,項目結構：如圖:

二，如何創建一個測試文件?

1,可以手動創建一個class文件

2,在intellij idea中可以快速創建一個test文件：

   打開一個service類，在類名上執行:  ctrl+shift+T

   然后從彈出的窗口中選擇:

    Create New Test

   如圖:

 

三，java代碼說明

1,service/HelloService.java

package com.servicetest.demo.service;

import org.springframework.stereotype.Service;

@Service
public class HelloService {

    public String sayHello(String name) {
        return "您好,"+name+"!";
    }

    public int addTwo(int first,int second) {
        return first+second;
    }
}

 

2,service/HelloServiceTest.java

package com.servicetest.demo.service;

import org.junit.jupiter.api.*;
import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.CsvSource;
import org.springframework.boot.test.context.SpringBootTest;

import javax.annotation.Resource;

import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.*;
import static org.hamcrest.Matchers.equalTo;
import static org.junit.jupiter.api.Assertions.*;

@SpringBootTest
@DisplayName("測試HelloService")
class HelloServiceTest {
    @Resource
    HelloService helloService;

    @BeforeAll
    static void initAll() {
        System.out.println("this is BeforeAll");
    }

    @AfterAll
    static void endAll() {
        System.out.println("this is AfterAll");
    }


    @BeforeEach
    public void initOne() {
        System.out.println("this is BeforeEach");
    }

    @AfterEach
    public void endOne() {
        System.out.println("this is AfterEach");
    }

    @Test
    @DisplayName("測試sayhello方法")
    void sayHello() {
        String hellostr = helloService.sayHello("老劉");
        assertThat(hellostr, equalTo("您好,老劉!"));
        assertThat(hellostr, hasLength(6));
        assertThat(hellostr, containsString("您好,"));
    }

    @ParameterizedTest
    @CsvSource({"1,2,3", "11,12,23", "33,100,133"})
    @DisplayName("參數化測試")
    void addTwo(int first,int second,int sum) {
        int rest = helloService.addTwo(first,second);
        assertThat(rest, equalTo(sum));
    }

}

 

四，測試效果

 

 

五，查看spring boot的版本:
