TestNG + Spring集成測試

在本教程中，我們將演示如何使用TestNG測試Spring的組件。

使用的工具 ：

• TestNG 6.8.7
• Spring 3.2.2.RELEASE
• Maven 3
• Eclipse IDE

1. 項目依賴

爲了演示，首先創建一個名稱爲：TestngSpringIntegration 的 Maven 項目。

要將Spring與TestNG集成，您需要spring-test.jar包依懶，添加以下內容：

創建文件：pom.xml 配置代碼如下 -

<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組件

創建一個簡單的Spring組件，稍後將使用TestNG來測試這個組件。

創建一個Java接口文件：EmailGenerator.java ，代碼如下 -

package com.yiibai;

public interface EmailGenerator {

    public String generate();

}

創建一個Java類文件：RandomEmailGenerator.java ，代碼如下 -

package com.yiibai;

import org.springframework.stereotype.Service;

@Service
public class RandomEmailGenerator implements EmailGenerator {

    public String generate() {
        return "[email protected]";
    }

}

3. TestNG + Spring

在 test 文件夾中創建一個Spring配置文件，用於Spring組件掃描。

創建一個XML文件：*${project}/src/test/resources/spring-test-config.xml* ，代碼如下 -

<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>

要訪問TestNG中的Spring組件，擴展AbstractTestNGSpringContextTests，請參閱以下示例：

創建一個Java文件：*${project}/src/test/java/com/yiibai/TestSpring.java* ，代碼如下 -

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, "[email protected]");


    }

}

執行上面測試代碼，輸出以下結果 -
