Xcode 12 中新多平台模板的共享单元测试

Question

How do you test the shared portion of code when you have a multiplatform project? I see tests for iOS and tests for macOS, but nothing for the shared pieces. I want to add unit tests for the platform-independent portion of my app.

Answer 1

Required

The most important part is to import the module to the test target:

The @testable word means that this test can access the internal stuff of the imported module.

_{Also, note that the MultiplatformAPP is the name of my project. You should look for the name of your project, instead.}

✅ Now you can access to the shared section and test it as you like. But there are some extra optional works you can do:

Optionally

1. You can build a custom bundle for your shared test:

Note that is doesn't matter what template group you are choosing this template from. It's a template. you can change it to anything else anytime. So we started with tvOS ♂️

2. Then you can nake it independent to any of the targets or depends on any of them you prefer to test with:

Note that I have named it Tests shared to match the pattern of the default tests naming convention of the multiplatform app.

Answer 2

Think we managed to figure this out.

If you go to File > New > Target...

In the Multiplatform section there isn't many options, but in iOS there is a Testing bundle named "Unit Testing Bundle"

If you add that and name it "Tests Shared"

You can then unit test against files that are part of the Shared target
