Spring Boot tutorial 14--integration test

Integration testing typically requires the interaction of different objects from different layers, such as databases, network connections, IOC containers, and so on.

Spring provides top-level support for integration testing through the Spring TestContext framework. It does not depend on a specific test framework, it can be used with junit, or it can use testng.

MAVEN-built projects default to the catalog of tests: Src/test/java (test code), Src/test/resources (test Resource), and Src/main/java (project source), Src/main/resources ( Project resources).

Spring provides a Springjunit4classrunner class that provides the functionality of the Spring TestContext framework. Configure application Context through @contextconfiguration to determine the profile of the activity through @activeprofiles.

After using the spring test, the "Run" section of our previous example can use the spring test to verify that the functionality works.

Example

1> Increase the dependency of the spring test in Pom.xml

<!--Spring Test Support -        <Dependency>            <groupId>Org.springframework</groupId>            <Artifactid>Spring-test</Artifactid>            <version>${spring-framework.version}</version>        </Dependency>        <Dependency>            <groupId>Junit</groupId>            <Artifactid>Junit</Artifactid>            <version>4.11</version>        </Dependency>

2> business code (SRC/MAIN/JAVA)

 Packagecom.wisely.highlight_spring4.ch3.fortest; Public classTestbean {PrivateString content;  PublicTestbean (String content) {Super();  This. Content =content; }     PublicString getcontent () {returncontent; }     Public voidsetcontent (String content) { This. Content =content; }    }

3>. Configuration Class (Src/main/java)

 Packagecom.wisely.highlight_spring4.ch3.fortest;ImportOrg.springframework.context.annotation.Bean;Importorg.springframework.context.annotation.Configuration;Importorg.springframework.context.annotation.Profile; @Configuration Public classtestconfig {@Bean @Profile ("Dev")     PublicTestbean Devtestbean () {return NewTestbean ("From Development profiles"); } @Bean @Profile ("Prod")     PublicTestbean Prodtestbean () {return NewTestbean ("From Production profiles"); }}

4> test (Src/test/java)

 Packagecom.wisely.highlight_spring4.ch3.fortest;ImportOrg.junit.Assert;Importorg.junit.Test;ImportOrg.junit.runner.RunWith;Importorg.springframework.beans.factory.annotation.Autowired;ImportOrg.springframework.test.context.ActiveProfiles;Importorg.springframework.test.context.ContextConfiguration;ImportOrg.springframework.test.context.junit4.SpringJUnit4ClassRunner; the @RunWith (Springjunit4classrunner.class)//Springjunit4classrunner provides the functionality of the Spring TestContext framework in a junit environment@ContextConfiguration (classes = {Testconfig.class})//@ContextConfiguration used to load the configuration ApplicationContext, where the classes property is used to load the configuration class@ActiveProfiles ("prod")//@ActiveProfiles used to declare the profile of an activity Public classdemobeanintegrationtests {@Autowired//you can inject beans using normal @autowired.
