I am trying to write a unit test for the save-as action of an editor using Mockito.

I created a temporary folder, a Mock WorkspaceRoot, and there are two files with coresponding IPaths:
    public TemporaryFolder tempFolder = new TemporaryFolder();
    IPath newFilePath;
    IPath originalFilePath;
    File newFile;
    File originalFile;
    private WorkspaceRoot root;

Afterwards I set the root location to the tempFolder, created the files and set the paths accordingly:
        File location = tempFolder.newFolder("someNewFolder");
        IPath path= new Path(location.getAbsolutePath());
        newFile=new File(location, NEW_FILE);
        originalFile=new File(location, ORIGINAL_FILE);
        newFilePath=new Path(newFile.getAbsolutePath()).makeRelativeTo(root.getLocation());
        originalFilePath=new Path(originalFile.getAbsolutePath()).makeRelativeTo(root.getLocation());

The plan is to call the
performSaveAsAction(IWorkspaceRoot root, IPath newPath, IPath originalPath)
with the mocked workspace root and the path for the files that I created, like this:
performSaveAsAction(root, newFilePath, originalFilePath)

This should create a new file using the newFilePath with the contents of the file found at originalFilePath.
But I cannot set the root to return either of the files, as the getFile() method needs to return an IFile and both files are


Any ideas on how to set the root to return the files I created, or how I could create IFiles in the desired directory, without setting up a whole project?

Thank you!
