Running tests using maven displays classpath problems

Question

I am attempting to run some unit tests on my spring web app using Maven. The app installs and runs fine without tests.

I receive this error in my surefire test report :

java.lang.NoClassDefFoundError: javax/servlet/ServletException

The test itself looks like this :

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"file:C:/myProjects/myWebapp/src/main/webapp/WEB-INF/applicationContext-test.xml"})
@Transactional
public class MyTest {
...

Previously I was receiving this error, however I removed any reference to the security package from test app context. And got this latest error.

Both problems are caused by my classpath not being set correctly ? The maven dependencies do not seem to be included when testing ? How can I change this, or what else am I missing ?

Answer 1

Try this.

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>test</scope>
</dependency>

Your servlet container will have this but some of your tests must need it. You may need to adjust the version.

The scope is important. You don't want to bundle this jar into your war but you want it available to your tests.
