maven spring test application contexts

I want to use the applicationContext.xml in my src/main/resources directory from within my test harness in src/test/java. How do I load it? I have tried:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:applicationContext.xml")
public class TestService {
...
}

but get a file not found error. I'm using Maven and Spring. Thanks.

Here's how I do it, it may or may not be the best way for you. The main thing is it works in both Eclipse and Maven:

  • Keep exactly one copy of each applicationContext-xxx.xml file per project. NEVER copy-and-paste them or their contents, it'll create a maintenance nightmare.

  • Externalize all environmental settings to properties files (e.g. database-prod.properties and database-test.properties) and place them in src/main/resources and src/test/resources respectively. Add this line to your app contexts:

    <context:property-placeholder location="classpath:**/*.properties"/>

  • Create a superclass for all test classes and annotate it with a context configuration:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:applicationContext.xml"})
@Ignore
public class SpringEnabledTest {

  // Inheritable logger
  protected Logger logger = LoggerFactory.getLogger(this.getClass());

}

  • Add <additionalClasspathElements> to your maven-surefire-plugin configuration to make sure surefire picks up appContext and the right properties files. I've created an example here.

  • Add the location(s) of the app context files and src/test/resources to your Eclipse classpath so you can execute unit tests in Eclipse as well.

  • NEVER add src/main/resources to your Eclipse classpath, it's only a convenient place for Maven to package additional source files, it should have no bearing on Eclipse. I often leave this directory blank and create additional folders (e.g. env/DEV, env/UAT and env/PROD) outside of the src/ folder and pass a parameter to the build server and let it know from which folder it needs to copy files to src/main/resources.

Try this (note the asterisk):

@ContextConfiguration("classpath*:applicationContext.xml")

The Maven test classpath uses the files in target/test-classes. That folder contains Java classes from src/test/java and resources from src/test/resources.

The way to go is to create a test specific app context and store it under src/main/resources.

You may try to reference the file directly using file: i.e. something like file:src/main/resources/applicationContext.xml but to me this is an ugly hack.

Also, you can of course use the Maven resources plugin to copy applicationContext.xml prior to test execution.

Add the src folder to the classpath of your testing tool. If it's in Eclipse, I think you can do it from the project properties. You may have to change it to classpath:**/applicationContext.xml as well.
