Run the test. When the file selection dialog box appears, select input2.txt to allow

MATLAB to proceed with the test. Selecting any other file results in a test failure.

results = runtests('LaunchAppTest');

Create Fully Automated Test

To test the app without manual intervention, use the mocking framework. Modify the app

to accept a file-choosing service instead of implementing it in the app (dependency

injection).

Create a FileChooser service with an Abstract method that implements the file

selection functionality.

classdef FileChooser

% Interface to choose a file

methods (Abstract)

[file,folder,status] = chooseFile(chooser,varargin)

end

end
