Swift XCTest UI tests with Realm

I'm developing my UI test with Swift 3.0 using Realm 2.4.2.

UI test target

Application

How can I "see" both on test target and application same realm objects?

What I do not want to do is using the launchArguments workaround delegating app to create objects.

You cannot "see" the same Realm objects in your UITest target and your Application because those two are running as completely separated processes.

From Apple's docs:

UI testing exercises your app's UI in the same way that users do without access to your app's internal methods, functions, and variables. ... Your test code runs as a separate process, synthesizing events that UI in your app responds to.

In other words: Your UITests are running in a separate App that interacts with your main App (when you run a UITest you can see the Testrunner App being launched and closed before your main App is being launched). Those two apps can not share objects.

I see two directions that you could go:

1. Create the cat objects via your app's UI

Somewhere you probably have a "Add cat" button. Press that in your UITest, add a cat like a use would and then assert that the cat has been added to the list. That is what UITests are for. Using the app like a user would and testing the results of a user's interaction with the app.

2. Use UnitTests:

If you want to test that a created Realm cat object is populating a list a UnitTest might be the better way. During a UnitTest you have full access to your app's code. So you can create a cat object in your test code and the app will "see" it.
