Added rootDir to mergedBabelTransformOptions #12331
Conversation
Running jest from a different working directory other than the project root causes the babel configuration to fail to load. The Babel configuration accepts a "root" argument, however, babel-jest is not currently passing this along.

CI is super unhappy 😃 Also, this needs a test to show what this enables that the current approach doesn't. |

@SimenB thanks for the quick response, yeah I saw the build failures. Trying to debug an issue with a Bazel build using jest+babel here. Just wanted to test the waters and see if my small change would break anything. Still investigating, so will address this when I get a working solution. |

Summary
I am currently working with a monorepo project where the root directory of the UI module is a subdirectory the project's root directory. Both my
jest.config.jsonandbabelrc.jsonfiles are in the UI module's root dir. The build tool we are using for our project forces us to run Jest from the project root, rather than the UI module's root. Jest uses the directory of thejest.config.jsonfile by default, but babel uses the current working directory.In order to fix this, babel-jest must set the
rootoption in the babel configuration to jest'srootDir.
