 By default, ngMock will create an injector per test case to ensure your tests do not affect each other. However, if we want to use `beforeAll()`, ngMock will have to create the injector before any test cases are run, and share that injector through all the cases for that `describe`. That is where {@link angular.mock.module.sharedInjector module.sharedInjector()} comes in. When it's called within a `describe` block, a single injector is shared between all hooks and test cases run in that block.
