在本教學中,我們將演示如何使用TestNG測試Spring的元件。
使用的工具 :
為了演示,首先建立一個名稱為:TestngSpringIntegration 的 Maven 專案。
要將Spring與TestNG整合,您需要spring-test.jar
包依懶,新增以下內容:
建立檔案:pom.xml 組態程式碼如下 -
<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>${testng.version}</version>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<defaultGoal>compile</defaultGoal>
</build>
</project>
建立一個簡單的Spring元件,稍後將使用TestNG來測試這個元件。
建立一個Java介面檔案:EmailGenerator.java ,程式碼如下 -
package com.yiibai;
public interface EmailGenerator {
public String generate();
}
建立一個Java類檔案:RandomEmailGenerator.java ,程式碼如下 -
package com.yiibai;
import org.springframework.stereotype.Service;
@Service
public class RandomEmailGenerator implements EmailGenerator {
public String generate() {
return "[email protected]";
}
}
在 test
檔案夾中建立一個Spring組態檔案,用於Spring元件掃描。
建立一個XML檔案:${project}/src/test/resources/spring-test-config.xml ,程式碼如下 -
<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>
要存取TestNG中的Spring元件,擴充套件AbstractTestNGSpringContextTests
,請參閱以下範例:
建立一個Java檔案:${project}/src/test/java/com/yiibai/TestSpring.java ,程式碼如下 -
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]");
}
}
執行上面測試程式碼,輸出以下結果 -
