jest-sourcemaps

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
