How to determine what resources are available for tests using Maven?

The context for my problem is given here: How to configure pom for StrutsTestCase so that web.xml is found?

In my pom.xml I have included the following, with hopes of making various files available during tests:

<testResources>
  <testResource>
    <directory>src/test/java</directory>
    <includes>
      <include>*.*</include>
    </includes>
  </testResource>
  <testResource>
    <directory>webapp/WEB-INF</directory>
    <includes>
      <include>*.xml</include>
    </includes>
  </testResource>
</testResources>

My expectation is that everything in 开发者_如何学JAVAsrc/test/java will be available during tests, as will be web.xml, struts-config.xml in webapp/WEB-INF.

The web.xml file is not being found during tests. In troubleshooting this I have two problems.

1. I'm not completely sure where I am (or should be) telling my other code to look for web.xml
2. I have no idea how to verify that web.xml is available while tests are being run.

For now, I'm asking #2. How can I verify that the XML above is doing what I think it should, and making web.xml available for use in tests?

I think the problem with your configuration may be that you've included the "WEB-INF" as part of your <testResource>. What you probably want is something more like this:

<testResources>
    <testResource>
        <directory>webapp</directory>
    </testResource>
</testResources>

(Or, if you're using the Standard Directory Layout as mentioned here, the directory would instead be src/main/webapp.)

And, if you only want to include XML files in the WEB-INF directory, then you'll need some additional "includes" config:

<testResources>
    <testResource>
        <directory>webapp</directory>
    </testResource>
    <includes>
        <include>WEB-INF/*.xml</include>
    </includes>
</testResources>

In order to test that these files are actually available on the classpath during your test runs, you can do something like follows:

URL webXml = getClass().getClassLoader().getResource("WEB-INF/web.xml");
assumeNotNull(webXml);

(As mentioned here, the use of assumeNotNull is optional.)

Unless you need the deployment descriptors (i.e web.xml, struts-config.xml, etc.) on the test classpath itself (e.g. to be be looked up via classloader.getResource*), then there should be no need for you to add or modify the testResources in the POM. Try simply looking up the file in your test setup as follows:

File file = new File("webapp/WEB-INF/web.xml");
assumeTrue(file.exists());

(Note: The use of assumeTrue may be used to ensure that the file exists as a precondition prior continuing to execute the tests, but this method can be replaced as desired.)

---

I think you need to change the path to the xml files to include them in the path for your tests.

Try:

<testResource>
   <directory>src/main/webapp/WEB-INF</directory>
   <includes>
      <include>*.xml</include>
   </includes>
</testResource>
