Track Manual Tests

# Track manual tests

## Context

The FUNCTIONALITIES screen allows to keep track of test coverage by automatic tests.
Some functionalities cannot be automated.
For them, it would be nice to track manual tests.

## Expected

### Cartography : Edit
When editing a functionality, a new CLOB field would allow to enter one URL per line (one URL per manual test case):


### Cartography : New Column
In the CARTOGRAPHY screen, a new column will appear:

It will show the number of manual tests.

The filter should be able to show only functionalities with manual tests ("Y"), or only those without manual tests ("N"). +
Clicking one option will disable the other. +
Clicking the checked option will disable that filter.

The cell must be clickable (the number should be blue) to show the following popup:

Each link will open in a new tab (target blank).

### Coverage
When reporting coverage, each category will have a new "(including XXX manual tests)" indicator:

Start by locating the FUNCTIONALITIES edit screen, the CARTOGRAPHY screen, and the coverage-reporting entry point. Trace how functionality data and automatic test coverage are stored and displayed before determining where the manual-test URLs and counts belong. Done means users can enter one URL per line, filter and open manual tests from CARTOGRAPHY, and see manual-test counts in coverage.
