Junit + getResourceAsStream Returning Null

Not sure how this is possible. I re-read up on getResourceAsStream and it's always returning null.

InputStream source = this.getClass().getResourceAsStream("test.xml");

Right next to test.java in the Finder (using OS X and Eclipse) is test.xml

I can open it in TextWrangler and view it as existing with data inside.

This is a Junit test if it makes any difference. I went and looked at existing Junit tests on our system and I'm using it in the exactly same manner as a working example (as in where the file is located and the code itself).

What small difference could there be preventing I assume getClass() from returning the right path?

Thanks!

Solution 1:

It's not finding the resource on the classpath. If you are using junit and maven make sure the resources are copied on the target/test-classes by adding <include> file directive on <testResource> section

You can also find out the location of your class in the file system by using

this.getClass().getResource(".")

and checking to see if the resource is there

Solution 2:

getResourceAsStream() is using the CLASSPATH, and as such it will load from wherever your classes are, not your source files.

I suspect you need to copy your XML to the same directory as your .class file.

Solution 3:

In case you are using Maven, add this part to your pom.xml

<build>
    <testResources>
        <testResource>
            <directory>${project.basedir}/src/test/resources</directory>
        </testResource>
    </testResources>
</build>

Your test.xml and other resource files must be located in src/test/resources
