Use Jest with sourcemaps

This package contains a few utilities to add source map support to jest. To use it you must:

• install: npm install jest-sourcemaps
• override the test Environment: Add "testEnvironment": "jest-sourcemaps/lib/jsdom-env" or "testEnvironment": "jest-sourcemaps/lib/node-env" to your jest config in your package.json.
• replace babel-jest: Use the transformer here instead by adding "\\.jsx?$": "jest-sourcemaps/lib/transformer.js" to your jest.transform config.
• add the source-map-support hook by either setting "setupTestFrameworkScriptFile": "jest-sourcemaps/lib/testEnvSetup.js" in your jest config, or by requiring the module from your existing setup file
• make babel output sourcemaps: Set "sourceMaps": "both" in your .babelrc
• disable jest's cache: Run it with --no-cache
