CrossCutting: Add Web.Integration.Tests #486
Description
Previously we've relied on solid Core.UnitTests and Core.IntegrationTests as well as Web.UnitTests
This does not include any hosted tests where we involve AspNetCore for routing, ViewModel binding, authorisation etc.
Web.IntegrationTests should be added to cover paths in Web.
Started in #326
Ensure tests are executed in the pipeline, and contribute to our code-coverage metrics.
