Is there a correct way to use the util method to find paths for test resources?

I am writing a small test to read a CSV file (using testng). I found some code to do exactly this and some other lines to find the resources folder.

Now that I reuse this in other scripts, I thought I could just create a utility method instead of copying it:

public static String prepFilepath(Class c) {

    URL url = c.getResource("");
    String location = url.getPath();

    String packageName = c.getPackage().getName().replace(".", "/");

    int l = location.lastIndexOf(packageName);
    return location.substring(0, l);
}

and it is called by my test like this:

@Test
public void testImport(){
    File testFile = new File(ImportUtils.prepFilepath(this.getClass()), inputFileName);
    //...
}

However, I don't know if this is correct:

  • Can a class reference be passed as a parameter? (I've never done this before for such a small purpose.)
  • Are there any more elegant ways?
  • Is it good enough to justify use?

Edit: I am using testng

If the file is in the same package as the class, we can get the url of that file

URL url = getClass().getResource(fileName);


if we need to get a file from a url we can do it this way

File file = new File(url.toURI());
