  • moduleNameMapper – all css and scss files containing CSS styles will be stubbed out.
  • modulePaths – the root dir of the project is used as a location to search when resolving modules.
  • setupFiles – runs code before each test which sets up global variables required in the testing environment.
  • setupFilesAfterEnv – runs code which adds improved support for Console object and React components to the testing framework before each test.
  • snapshotSerializers – makes it possible to use snapshot tests on Enzyme wrappers.
  • testMatch– includes /test/ subfolder in the glob patterns Jest uses to detect test files. It detects only test files containing .js extension.
