You can execute the tests by running the following command from the root of this project:
cd src/xcode && fastlane test
Alternatively you can execute the tests by hitting ⌘U within Xcode.
In order to keep things simple we use XCTest as the basis for our tests. Tests are put into directories called __tests__. We want to have to tests as close as possible to the code they actually test.
Once things have stabilized we would like to split the app target up into multiple smaller frameworks. Each framework would then have it's own test target. By having multiple local __tests__-directories we accomentate this foreseeing change to some extent today.
Having multiple local __tests__-directories also makes it easier to see where tests are still missing.
There is a dedicated label called tests for issues that ask for tests. If you want to contribute tests to this project it is a good idea to look at the list of tests that still need to be done. Simply pick an issue, write tests for it, open a PR and wait for feedback.
Parts of the existing code may not be testable. If you spot code that you feel is not testable please open an issue and report this as a bug.
