Jest fails to parse TSX about enzyme-adapter-preact-pure HOT 2 CLOSED

I solved it by insert the babel-config: true in jest config.

The difference is that the babel-jest do not specified directly as a transform, and keep the ts-jest preset.

"preset": "ts-jest",
  "globals": {
    "ts-jest": {
      "babelConfig": true
  }
},

Hello,

First of all, your problem doesn't seem like it relates to this project directly. It seems like you're having trouble getting TypeScript + JSX to work inside Jest. I would recommend asking for help in Jest's community forums/chat as you're more likely to find the right experts.

From the error messages you posted, it seems like Jest is parsing a JavaScript file containing JSX expressions and it isn't set up to handle that. To me this suggests that either you need to configure TypeScript to output plain JavaScript (not JavaScript + JSX) or you need to use another tool to convert TypeScript's JavaScript + JSX output to plain JavaScript. I guess this is what you were trying to do with babel-jest? One possible issue I can see is that your regular expression (^.+\\.ts$) does not match files than end with .tsx.

I'm closing this issue because I don't think there is an issue with the adapter, but please do post a comment here when you figure the problem out.
