How To Fix Missing Required Module In Your iOS Unit Test Target?

Starting TDD (Test-Driven Development)? Following a tutorial in Unit Testing? Testing your service functions? Whatever your case is, sometimes starting a unit test in Xcode if you have dependencies via Cocoapods.

I’ve started practicing TDD in my personal project some weeks ago and here I find myself doing Unit Testing in another project but I encountered this error:

Missing required module ‘Firebase’

As usual, the first step in figuring out what to do: search on Google. Next step I did was check out my project in which I did my very first TDD. One of the links that can help you before proceeding is this thread on Github.

GitHub Cocoapods Repository - Module Error ‘Google’

If none of the solutions you found on Google worked and if you’re using Firebase, then continue reading and follow these steps:

• Making your test target inherit the search paths of your main target.

Check out my podfile and see that the tests target is under the main target.

• Add a search path in your Header Search Paths

In your Tests target’s Build Settings, search for Header Search Paths and add these two new search paths:

$(SRCROOT)/Pods (recursive)
${PODS_ROOT}/Firebase/Core/Sources (non-recursive)

And… that’s it! You should be able to do your unit test. Sample unit test code?
