Failed to load ApplicationContext at TestContext.getApplicationContext

**gerjan** · Oct 2nd, 2012, 07:22 AM

Hi,

I'm having a problem loading my test application context (same result with either STS m2eclipse or 'mvn clean test' from a shell). Does anyone see what's wrong in my setup? Thanks in advance for your suggestions!

Here's my test (it looks odd because it just waits 1s before doing an assert - that's because it attempts to test the effect of a @Scheduled annotated processor which is instantiated by the application context):

Code:

package nl.rivm.vubis2warp.task.impl;

import org.junit.Test;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;
import org.springframework.util.Assert;

@ContextConfiguration(locations={"classpath:/nl/rivm/vubis2warp/task/impl/test-context.xml"})
public class SchedulerImplTest extends AbstractJUnit4SpringContextTests {

	@Test
	public void test() throws InterruptedException {
		Thread.sleep(1000);
		Assert.notNull(this.getClass().getResource("/work/sent/210231001.xml"));
	}

}

I verified that Maven's resource plugin copies my test-context.xml from /src/test/resources/nl/rivm/vubis2warp/task/impl to /target/test-classes/nl/rivm/vubis2warp/task/impl.

However, Spring's TestContext fails to load the ApplicationContext, because class path resource [nl/rivm/vubis2warp/task/impl/test-context.xml] does not exist. Also tried moving test-context.xml to /src/test/resources/ and changing @ContextConfiguration as follows, but to no avail:

@ContextConfiguration(locations={"classpath:/test-context.xml"})
@ContextConfiguration(locations={"classpath:test-context.xml"})
@ContextConfiguration(locations={"test-context.xml"})

Below is the stack trace plus some preliminary log output (org.springframework.test at debug level):

In general if the file cannot be loaded it either isn't there or isn't readable...

Sometimes it is quite a battle, at least that is my personal experience, combining Eclipse and Maven commandline, I found a lot of cases where directories get cleaned, binaries removed etc. so it could be both are competing on a directory. In general I try to clean the project, force a recompile and start everything again (all from within Eclipse, whilst nog using maven).

**gerjan** · Oct 2nd, 2012, 08:21 AM

Hi Marten,

Thanks for your quick response. The approach you suggested works: clean + build, then run as JUnit test (either project or test class).

I also tried the Maven only option: copied working folder outside the reach of Eclipse/STS, then it ran 'mvn clean test' followed by 'mvn test', but test-context.xml isn't found in either of the runs. Even if for some reason (TestContext tries to load the application context before Maven finishes copying resources?) the file isn't there in the first run, shouldn't TestContext find the missing file the second time round (skipping clean, so leaving the target subtree in place)?

Any thoughts?

Thanks again,

Ger-Jan

When you run mvn test clean I would check if the file is there. Could be that there is some problem with a maven plugin (maven-resources-plugin) or configuration of a plugin (skipping the copying of xml files for instance).

When the files are copied you should see something like below in your maven output...

Code:

[INFO] --- maven-resources-plugin:2.5:resources (default-testResources) @ myproject ---
[INFO] Using 'UTF-8' encoding to copy filtered resources.
[INFO] Copying 1 resource

**gerjan** · Oct 2nd, 2012, 08:49 AM

The file is there allright, I checked again and again. And the copy action itself shows up in the output of mvn -X clean test:

Hmm strange... Also, judging from the path, you are on a Unix based system is the file readable (I would expect so because you can also copy the file)... Another thing to check is the configuration/classpath when executing the surefire plugin (might be that it isn't on the classpath)...

**gerjan** · Oct 2nd, 2012, 09:41 AM

Bingo. The file is readable, but your suggestion to check the surefire plugin config paid off.

In order to be able to debug the test in STS I inserted this forkmode config element for surefire in the pom:

Code:

<configuration>
	<forkMode>none</forkMode>
</configuration>

If I comment it out again, the app context file not found problem disappears. I would think the classpath for the non-forked surefire differs from the default one. This should show in Maven's debug output, but no, the different debug outputs even claim to use the same classpaths (screenshot attached).

Anyway; I guess I have to do without debugging tests if I wish to run my tests in a Maven build.

Thanks once again for your help!

OK, uploading screenshots doesn't seem to work for me. I've included relevant outputs instead (some longer lines removed):
