In this phase you will write a basic version of the web application that can display but not create job listings. This means we don t yet have to worry about login and sessions but that you must interface to the database to lists positions. Following the model-view-controller architecture, the first thing that you ll implement is the database model. This is contained in a module interface.py with all of the code to retrieve and store positions in the database. You will then implement the views (templates) and controllers for the web application that makes use of the models present the data on the web. All of the work you do will be tested using unit tests. For the database interface, there are straightforward unit tests of the functions that you will write. To test the behaviour of the web application we ll use functional testing that requests your pages and checks that they have certain contents, and that we can login and position messages. We will do this using a module called WebTest that is designed specifically for functional testing of Python web applications. Unit Tests All procedures will be implemented in the module interface.py. A version has been supplied that contains the procedure stubs only. When we refer to a database connection below we mean the connection returned by COMP249Db from the database module that we provide. This is just a regular SQLite database connection, but the code we provide ensures we can control which database you are using for testing purposes.
