Getting resources from Unit Tests

Since Unit Tests are run from the command line( or Ant ) access to Resources of a WebObjects project are no good with ResourceManager. Simple functions to get resources based on the filesystem:

/**
 * Returns a path to a resource filename in a folder(s) under the root folder
 * */
private String resourceLocationString( String filename, String folder ) {
    String urlToFile = getClass().getResource( "/" ).toString();
    urlToFile = urlToFile.replace( "bin/", "" );
    urlToFile = urlToFile.replace( "file:", "" ); // now we should be at the projects root directory
    urlToFile = urlToFile.concat( folder + "/" + filename );
    return urlToFile;
}

/**
 * Returns data for pdf file
 * */
private byte[] bytesForPDFResource( String urlToFile ) throws FileNotFoundException, IOException {
    FileInputStream in = new FileInputStream( urlToFile );
    byte[] data = new byte[in.available()];
    in.read(data);
    return data;
}

Write data to a file in the filesystem

FileOutputStream fs = new FileOutputStream( ABSOLUTE_PATH_TO_FILE );
fs.write( SOME_DATA );
fs.close();
