Ts-jest: Disabling diagnostics doesn’t work

[remcohaszing]

Issue

I am unable to disable ts-jest diagnostics.

I’m using the following jest.config.js:

module.exports = {
  preset: 'ts-jest',
  globals: {
    'ts-jest': {
      diagnostics: false,
    },
  },
};

This outputs

ts-jest[config] (WARN) TypeScript diagnostics (customize using `[jest-config].globals.ts-jest.diagnostics` option):
message TS151001: If you have issues related to imports, you should consider setting `esModuleInterop` to `true` in your TypeScript configuration file (usually `tsconfig.json`). See https://blogs.msdn.microsoft.com/typescript/2018/01/31/announcing-typescript-2-7/#easier-ecmascript-module-interoperability for more information.

Expected behavior

Diagnostics are disabled

hi @remcohaszing , is this issue still occurred in ts-jest 24.1.0 ? If yes, would you please provide us a minimum reproduce repo ?

[remcohaszing]

Yep. I encountered this in a fairly small repository, mini-jsx. I just upgraded everything to their latest versions and the warning is still logged.

The latest test output can be seen here.

[domske]

Same here. I can't disable the diagnostic messages. Not all or by message code.

jest.config.js:

module.exports = {
  preset: 'ts-jest',
  testEnvironment: 'node',
  globals: {
    'ts-jest': {
      diagnostics: false
    }
  }
};

package.json (Snippet)

{
  "devDependencies": {
    "@types/jest": "^24.0.23",
    "jest": "^24.9.0",
    "ts-jest": "^24.1.0",
    "typescript": "^3.7.2",
  }
}

Console

ts-jest[config] (WARN) TypeScript diagnostics (customize using `[jest-config].globals.ts-jest.diagnostics` option):
message TS151001: If you have issues related to imports, you should consider setting `esModuleInterop` to `true` in your TypeScript configuration file (usually `tsconfig.json`). See https://blogs.msdn.microsoft.com/typescript/2018/01/31/announcing-typescript-2-7/#easier-ecmascript-module-interoperability for more information.

hi, the log you saw actually came from this logger line. This logging is more like a warning, disabling diagnostics means if there is a compilation issue, ts-jest won't throw error.

Disabling diagnostics itself works, just the logging is misunderstood. I will close this issue as it's not broken functionality. ts-jest can adjust the documentation to make clear about this diagnostic logging or you can submit a PR to adjust the documentation.
