在本教程中,我们将演示如何使用TestNG测试Spring的组件。
使用的工具 :
- TestNG 6.8.7
- Spring 3.2.2.RELEASE
- Maven 3
- Eclipse IDE
1. 项目依赖
为了演示,首先创建一个名称为:TestngSpringIntegration 的 Maven 项目。
要将Spring与TestNG集成,您需要spring-test.jar
包依懒,添加以下内容:
创建文件:pom.xml 配置代码如下 -
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.yiibai</groupId>
<artifactId>TestngSpringIntegration</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<name>TestngSpringIntegration</name>
<url>http://maven.apache.org</url>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<spring.version>4.0.6.RELEASE</spring.version>
<testng.version>6.8.7</testng.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>${testng.version}</version>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<defaultGoal>compile</defaultGoal>
</build>
</project>
2. Spring组件
创建一个简单的Spring组件,稍后将使用TestNG来测试这个组件。
创建一个Java接口文件:EmailGenerator.java ,代码如下 -
package com.yiibai;
public interface EmailGenerator {
public String generate();
}
创建一个Java类文件:RandomEmailGenerator.java ,代码如下 -
package com.yiibai;
import org.springframework.stereotype.Service;
@Service
public class RandomEmailGenerator implements EmailGenerator {
public String generate() {
return "feedback@yiibai.com";
}
}
3. TestNG + Spring
在 test
文件夹中创建一个Spring配置文件,用于Spring组件扫描。
创建一个XML文件:${project}/src/test/resources/spring-test-config.xml ,代码如下 -
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd
">
<context:component-scan base-package="com.yiibai" />
</beans>
要访问TestNG中的Spring组件,扩展AbstractTestNGSpringContextTests
,请参阅以下示例:
创建一个Java文件:${project}/src/test/java/com/yiibai/TestSpring.java ,代码如下 -
package com.yiibai;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.testng.AbstractTestNGSpringContextTests;
import org.testng.Assert;
import org.testng.annotations.Test;
import com.yiibai.EmailGenerator;
@Test
@ContextConfiguration(locations = { "classpath:spring-test-config.xml" })
public class TestSpring extends AbstractTestNGSpringContextTests {
@Autowired
EmailGenerator emailGenerator;
@Test()
void testEmailGenerator() {
String email = emailGenerator.generate();
System.out.println(email);
Assert.assertNotNull(email);
Assert.assertEquals(email, "feedback@yiibai.com");
}
}
执行上面测试代码,输出以下结果 -
五月 04, 2017 00:26:07 上午 org.springframework.test.context.TestContextManager retrieveTestExecutionListeners
信息: Could not instantiate TestExecutionListener [org.springframework.test.context.web.ServletTestExecutionListener]. Specify custom listener classes or make the default listener classes (and their required dependencies) available. Offending class: [javax/servlet/ServletContext]
