使用TestNG替代Junit作为单测框架，如何和Spring/Spring Boot整合？

Spring+TestNG+Maven整合：

1.引入spring依赖：
spring-core/spring-context/spring-beans/spring-test

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
        </dependency>

2.引入testng依赖：

<dependency>
      <groupId>org.testng</groupId>
      <artifactId>testng</artifactId>
      <version>6.8.8</version>
      <scope>test</scope>
</dependency>

3.测试类增加1条注解
@ContextConfiguration(locations = "classpath:applicationContext.xml")并继承AbstractTestNGSpringContextTests，范例如下：

@ContextConfiguration(locations = "classpath:applicationContext.xml")
public class BaseTest extends AbstractTestNGSpringContextTests{
    @Test
    public void testMethods()
    {
        ......
    }
}

4.如果spring的配置没有使用xml，而是通过代码配置，第3步需要做下调整：

• 举例通过代码配置spring（效果和xml配置是相同的）：

@Configuration
public class SpringConfig {
     @Bean(name = "xxxBean", initMethod = "init")
     public XxxBean xxxBean() {
        ......
     } 
}

• 代码配置spring情况下，没有xml配置文件，测试类：

@ContextConfiguration(classes = {SpringConfig.class})
public class BaseTest extends AbstractTestNGSpringContextTests{
    @Test
    public void testMethods()
    {
        ......
    }
}

Spring换成Spring Boot：

Spring Boot对Junit4的支持比TestNG更好，但是如果坚持用TestNG的话可以参考spring-boot-sample-testng

1.引入spring-boot依赖：
引入测试依赖：

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-test</artifactId>
            <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-test</artifactId>
        <scope>test</scope>
    </dependency>

2.引入TestNG依赖：

        <!--TestNG-->
        <dependency>
            <groupId>org.testng</groupId>
            <artifactId>testng</artifactId>
            <scope>test</scope>
        </dependency>

3.测试代码添加@SpringBootTest注解

@SpringBootTest
public class SampleTestNGApplicationTests extends AbstractTestNGSpringContextTests {

    @Autowired
    private TestRestTemplate restTemplate;

    @Test
    public void testHome() throws Exception {
        ......
    }
}

@SpringBootTest可以通过classes属性指定Spring配置类，如果不指定，会自动查找有@SpringBootApplication或者SpringBootConfiguration的类作为Spring配置类。

@SpringBootTest(classes = {Application.class})
public class SampleTestNGApplicationTests extends AbstractTestNGSpringContextTests {

    @Autowired
    private TestRestTemplate restTemplate;

    @Test
    public void testHome() throws Exception {
        ......
    }
}

@SpringBootApplication(scanBasePackages = {"xxx.xxx.xxx"})
public class Application{

}
