It is currently not possible to call `hasOwnProperty` on the proxy instance, which makes it impossible to spy with Jest, as Jest needs to call this method (see https://github.com/facebook/jest/blob/30e802036291f4c9c9fd4feef6faba485df54dd2/packages/jest-mock/src/index.ts#L986) This commit fixes this by properly returning the `hasOwnProperty` method in the `get` section of the proxy. There is currently a workaround in vue-test-utils-next that monkey patches the proxy to add the method (see https://github.com/vuejs/vue-test-utils-next/blob/23d3d3e1f4178a87de5023f5255e0623653affdc/src/mount.ts#L493-L495). This is temporarily fine, but developers trying to create spies without using @vue/test-utils will run into the same issue.

I feel this is something that should be fixed in Jest - its usage of Instead it should use |

Sounds good. I opened jestjs/jest#11721 in Jest itself |

The PR landed in Jest, and was released as v27.1 PR #4472 updates vue-next to use this new version which fixes the issue, making this PR obsolete |

The proposed fix is obviously very naive: the point was just to get the ball rolling 馃檪
