How to configure pom for StrutsTestCase so that web.xml is found?

Question

I'm using Maven 2 to build a Java - Sturts 1.2 - Spring 1.2 project. I'm trying to incorporate the StrutsTestCase extension of JUnit to allow testing of action classes.

When I try to build, I get the following error:

junit.framework.AssertionFailedError: The /WEB-INF/web.xml was not found.
  at servletunit.struts.MockStrutsTestCase.getActionServlet(MockStrutsTestCase.java:344)
  at servletunit.struts.MockStrutsTestCase.tearDown(MockStrutsTestCase.java:130)

In researching this, I've learned the following:

1. If your web.xml file is in a non-standard location, then setServletConfigFile() can be used to indicate to StrutsTestCase where the file is.
2. When building with Maven, it may be necessary to indicate what resources should be included in the pom.xml .

I'm trying to implement this, here is my current progress:

Test class:

import servletunit.struts.MockStrutsTestCase;

public class FooActionTest extends MockStrutsTestCase {

  public void setUp() throws Exception {
  super.setUp();
  setServletConfigFile("webapp/WEB-INF/web.xml");
}

public void testTest() throws Exception { /* stub, no content */ }

I have included the following testResources in the build tag in the pom.xml .

<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>

Here is the structure of the project:

myproject
│---src
│   |---main
|   |   |---java
|   |
|   |---test
|       |---Java
|
|---target
|   |---classes
|   |
|   |---MYPROJECT
|       |---META-INF
|       |---WEB-INF
|           |---struts.config.xml
|           |---web.xml
|
|---webapp
|   |---META-INF
|   |---WEB-INF
|       |---struts.config.xml
|       |---web.xml
|---pom.xml

Of course, I've tried a variety of variations of the paths in pom.xml and in setServletConfigFile . I've also tried using setContextDirectory , with no different result.

I'm using the default Maven webapp structure

myproject
|---src
|   |---main
|   |   |---java
|   |
|   |---test
|   |    |---Java
|   |
|   |---webapp
|        |---WEB-INF
|             |---struts.config.xml
|             |---web.xml
|
|---pom.xml

I'm adding webapp XML files to my test resources and I don't need to call setServletConfigFile method .

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

So, in your case, you should add these lines in your POM file:

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

I think the easiest way to do this is through property that holds a path to web.xml .

This way you can simply pass the property value to surefire plugin

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
      <systemPropertyVariables>
        <test.web-xml.file>${project.build.directory}/MYPROJECT/WEB-INF/web.xml</test.web-xml.file>
      </systemPropertyVariables>
    </configuration>
  </plugin>

Then in your setup method just get a system property:

  public void setUp() throws Exception {
    super.setUp();
    // You may want to do some validation if this property is set and
    // points to a file
    setServletConfigFile( System.getProperty("test.web-xml.file") );
  }
