Legacy

Getting started the legacy mobile app done in .NET MAUI.

Configure Git blame

We recommend that you configure git to ignore the Prettier revision:

git config blame.ignoreRevsFile .git-blame-ignore-revs

Unit tests

TL;DR;

In order to run unit tests add the argument /p:CustomConstants=UT on the dotnet command for building/running. To work on Unit testing or use a Test runner uncomment the CustomConstants line on the Directory.Build.props

Given that the Core.csproj is a MAUI project with net8.0-android;net8.0-ios target frameworks and we need net8.0 for the tests we need a way to add that. The Core.Test.csproj has net8.0 as a target so by adding the the argument /p:CustomConstants=UT we add UT as a constant to use in the projects. With that in place the next things happen:

• UT is added as a constant to use by precompiler directives
• Core.csproj is changed to add net8.0 as a target framework for unit tests
• FFImageLoading is removed as a reference given that it doesn’t support net8.0. Because of this, now we have a wrapped CachedImage that uses the library one if it’s not UT and a custom one with NOOP implementation for UT

So if one wants to build the test project, one needs to go to test/Core.Test and run:

dotnet build -f net8.0 /p:CustomConstants=UT

and to run the tests go to the same folder and run:

dotnet test -f net8.0 /p:CustomConstants=UT

Finally, when working on the Core.Test project or when wanting to use a Test runner, go to the Directory.Build.props (located in the root) and uncomment the line referencing CustomConstants so that everything is loaded accordingly in the project. Because of some issues, the referenced projects, e.g. Core, are only included when the UT constant is in place. By uncommenting this line the projects will be referenced and one can work on that project or run the tests from a Test runner.

Custom constants

There are custom constants to be used by the parameter /p:CustomConstants={Value} when building/running/releasing:

• FDROID: This is used to indicate that it’s and F-Droid build/release (want to know more?)
• UT: This is used when building/running the test projects or when working on one of them (want to know more?)

These constants are added to the defined ones, so anyone can use them in the code with precompiler directives.
