Jest matcher import is breaking webpack projects.

See original GitHub issue

The Issue

This project, or one of its dependencies, has an incorrect import path. This causes the test suite to crash whenever the rxSandbox.create() function is called.

The offending import is here: https://github.com/kwonoj/rx-sandbox/blob/master/src/assert/marbleAssert.ts

Steps to reproduce:

Create a new Angular project. Import rxSandbox and call the create() function.
