javaEE颠覆者十五

javaEE颠覆者第三章
3.7 测试
只对简单配置的ApplicationContext和在测试中注入Bean做演示
（1）准备pom.xml

（2）业务代码
src/main/java的源码

package spring4.fortest;

public class TestBean {
    private String content;
    public TestBean(String content) {
        super();
        this.content=content;
    }
    public String getContent() {
        return content;
    }
    public void setContent(String content) {
        this.content = content;
    }

}

（3）配置类

package spring4.fortest;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;

@Configuration
public class TestConfig {
    @Bean
    @Profile("dev")
    public TestBean devTestBean() {
        return new TestBean("from development profile");
    }

    @Bean
    @Profile("prod")
    public TestBean prodTestBean() {
        return new TestBean("from production profile");
    }
}

（4）测试
src/test/java的源码

package spring4.fortest;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)  //SpringJUnit4ClassRunner在JUit环境下提供SpringTestContextFramework的功能
@ContextConfiguration(classes = TestConfig.class) //@ContextConfiguration用来加载配置ApplicationContext，classes用来加载配置类
@ActiveProfiles("prod") //@ActiveProfiles用来声明活动的profile
public class DemoBeanIntegrationTests {
    @Autowired //可以用普通的@Autowired注入Bean
    private TestBean testBean;

    @Test //测试代码
    public void prodBeanShouldTnject() {
        String expected = "from production profile";
        String actual = testBean.getContent();
        Assert.assertEquals(expected, actual);
    }
}

结果

将@ActiveProfiles(“prod”)改为@ActiveProfiles(“dev”)演示测试不能通过的情景
结果：
