Academy 2.0 - Config excel file not read in _Test.xaml


Hello, I am currently doing the Academy 2.0 Training using the Uidemo application. I am working through the PDF for the first exercise of the academy 2.0 training. In the pdf it says "To test InitAllApplications, we need to run the _Test.xaml file, which first reads the Config file, and then invokes our file. " I do not believe the _test.xaml file is reading the config excel file and storing it as a dictionary. As a result I get an initialization error when trying to run the _test.xaml file because the file path for the application is not being supplied to my “InitAllApplications”.

Are we supposed to add a stage to read the config excel file and set up the config dictionary ourselves ?
