Getting Unknown Provider error when injecting a Service into an Angular unit test

Question

I\'m fairly new to Angular and have reviewed all the similarly related questions on Stack Overflow but none have helped me. I believe I have everything set up correctly but am s

Answer 1

While this question is fairly old i lost significant time solving a problem similar to this one, i.e.:

Error: Unknown provider: SomeServiceProvider <- SomeService

Hence, i'm leaving here another possible cause to this issue. Hopefully, it would helpful to someone.

In my case, i had in my project two modules with the exactly same name but with different dependencies being created, i.e., two different .js files with:

angular.module('moduleName', [dependencies]))

From angular documentation:

Passing one argument retrieves an existing angular.Module, whereas passing more than one argument creates a new angular.Module

Conclusion: It turns out that what was being injected in the test was the module with the wrong dependencies. Removing the second argument from the module that was erroneously being created solved the problem.
