RTW-313: Implement percentage completed UI

[andrejvelichkovski]

Description

This change implements a progress bar that indicates how many of the Test Executions in an Artefact have been completed ( reviewed).

There are two parts to this implementation:

1. Viewing it for a single artefact only - this case can be trivially computed on the frontend, without any changes on the backend
2. Viewing it for all artefacts on the dashboard page - this is more complicated to implement as we don't fetch all test executions when loading the artefacts on the dashboard page.

We solve case (1) with front-end only changes. To resolve case (2) we also implement a backend change, to expose the following two parameters for all artefacts available:

• all_test_executions_count
• completed_test_executions_count

UI component changes

Dashboard

Artefact View

Updated tooltip

Resolved issues

This PR resolves RTW-313.

Documentation

This is a UX improvement and we don't have any documentation for such components yet.

Web service API changes

The change adds two fields to the ArtefactDTO, both integers. There are currently two endpoints that return ArtefactDTO objects:

• /artefacts
• /artefacts/{ID}

Tests

This change was both manually tested and an automated test was added

Known limitations

Currently, we only fetch the dashboard page when we firstly load the page, to avoid making extra requests. This limits the correctness of data we show on the dashboard. Consider the following case:

1. The user loads the dashboard - the data is fresh from the DB
2. The user loads and approves one test executions in an artefact - the data is correctly shown in the top bar in the artefact view
3. The user goes back to the dashboard, the old data is still present as the front-end hasn't re-loaded the new data.

Very useful feature!

@omar-selo can you please help me verify that it is fine to assign revision to 0 if it is None. Mypy was complaining because the key here can be null.

[omar-selo]

I think this should be fine

Looks good to me
