So i worked a lot with maven, spring and junit, and on every project i faced the need to have my code under test and so i do each time. an i thought why not have a simple how to do so and so i do this post :D.
so let see what you need to have your own maven project running
so let see what you need to have your own maven project running
- JDK 1.6+.
- Maven.
- IDE or any text editor.
so my pom.xml looks like
and i have a simple model and simple service that use this model
as
package com.shereifhawary.spring;
public class SimpleModel {
private String value = "some value";
public String getValue(){
return this.value;
}
public void setValue(String value) {
this.value = value;
}
}

and i have a simple model and simple service that use this model
as
package com.shereifhawary.spring;
public class SimpleModel {
private String value = "some value";
public String getValue(){
return this.value;
}
public void setValue(String value) {
this.value = value;
}
}
package com.shereifhawary.spring;
public class SimpleService {
private SimpleModel model;
public SimpleModel getModel() {
return model;
}
public void setModel(SimpleModel model) {
this.model = model;
}
public String getValue(){
return model.getValue();
}
}
inside the src/test/resources/beans.xml which carry the bean definition
<beans xmlns="http://www.springframework.org/schema/beans"
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-3.0.xsd">
<bean id="simpleModel" class="com.shereifhawary.spring.SimpleModel">
<property name="value" value="some value from Spring config"/>
</bean>
<bean id="simpleService" class="com.shereifhawary.spring.SimpleService">
<property name="model" ref="simpleModel"/>
</bean>
</beans>
and the test case should be like
package com.shereifhawary.spring.tests;
import static org.junit.Assert.*;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import com.shereifhawary.spring.SimpleService;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/beans.xml" })
public class TestSpringContext {
// the autowire will set the simpleSerice object with the one in the bean.xml
// so you can use it inside the testcase without even using setup function
@Autowired
SimpleService simpleService;
@Test
public void testSimpleService(){
// as you can see we set the value with "some value" in the class itself,
// but inside the bean.xml we set it with "some value from Spring config
"
assertNotEquals("some value",simpleService.getValue());
assertEquals("some value from Spring config
",simpleService.getValue());
}
}
i hope you like it, if you have any questions please leave it below ;)
