Topic Overview
Prior Work
The previous team's wiki write-up contains detailed information regarding this feature. A summary of the desired functionality is presented below:
Overview of Major Changes
A new table was added to the database (grading_history), along with the corresponding model (grading_history.rb) and controller (grading_history_controller.rb).
Two models for specific types of histories were added: review_grading_history.rb, and submission_grading_history.rb.
A view for displaying the grading history of a particular assignment or review was added (index_html.erb).
Modifications to Existing Files
- app/controllers/grades_controller.rb
- A grading history record is created for every edit to a submission's grade.
- app/controllers/review_mapping_controller.rb
- A grading history record is created for every edit to a review's grade.
- app/views/assignments/list_submissions.html.erb
- A link to access a submission's grade history is shown in the submissions table.
- app/views/reports/_review_report.html.erb
- A link to access a review's grade history is shown in the review report table.
Testing (NOTE: should probably remove this from here)
Functional tests ensuring specific method calls are made were added.
- functional tests added to these files
- spec/controllers/grades_controller_spec.rb
- spec/controllers/review_mapping_controller_spec.rb
- spec/controllers/grading_histories_controller_test.rb
A feature test ensuring that correct grading history is shown in chronological order was added.
- feature test handled by these two files
- spec/features/grade_histories_spec.rb
- spec/features/helpers/grade_histories_helper.rb
Whenever an instructor submits a new grade, or edits an existing grade, the grading_history_controller saves a new history entry to the database.
Statement of Problem
There are three areas of focus for this project:
System Crashes and Object Creation
First, the work done by the previous team results in the system crashing when the tests are being executed; as a result, automated unit testing does not succeed. Our goal in this regard is to ensure that the tests are successfully executed for all test cases, with the appropriate outcome and coverage reports visible to the user.
Second, testing efforts to this point have used static, pre-created objects; this is due to issues with object creation. Our goal in this aspect is to ensure that the creation of new test objects, namely Student Accounts, Assignments, and Project Bids is successful.
Changes to Grading History Table
The grading history table is earmarked for certain changes:
a. Extract Student ID from the table, and ensure that it is shown in the header
b. Extract Assignment ID from the table, and ensure that it is shown in the header
Code and Documentation Goals
Add reasonings and data flow structures/UML diagrams that detail the changes that have been made, as well as any comments on why certain files needed to be modified.
These will be completed from these perspectives:
a. From a data flow point of view
b. From a function point of view
c. With comment in code

Testing Goals and Test Objects
Drawing from the project objectives: 1. Verify that Student Accounts can be created and are saved to the database. 2. Verify that Assignments can be created and are saved to the database. 3. Verify that Project Bids can be created and are saved to the database. 4. Ensure that Student ID is shown in the header via RSpec, and verify via manual UI testing 5. Ensure that Assignment ID is shown in the header via RSpec, and verify via manual UI testing
General Testing Plan
RSpec Unit Tests
Manual UI Tests
Discussion with mentor in progress to determine if UI Automation testing is in scope
Regression Testing
In order to ensure complete coverage, testing of the changes done between the end of last semester and this project was done.
Note to team: need to edit this after investigation
1. Investigate if this is testable using Capybara
2. Get the specific format requirement for the title, and assert that it's there. Ensure that this doesn't appear anywhere else (possible via ensuring count is 1)
3. Procure specific required column width, and assert that this is the value in the file (the constant)
4. Inquire with mentor about comment requirement and conflicts
5. Inquire with mentor regarding white space constraints
6. Inquire why the revert is needed, what is breaking and why
7. Ask mentor where this file is being called, and if functionality needs to be moved elsewhere.
8. Complete Design Document to reflect these changes.
