Wallaby, TypeScript and Jest Mocks

[unstubbable]

Issue description or question

I can not get Jest mocks to work with wallaby. I read #1152 as well as #1181 (comment) but couldn’t find a config that works. This minimal example should help reproducing and hopefully fixing the issue. Here is also a summary of what’s configured there:

Wallaby.js configuration file

module.exports = function() {
  return {
    files: ["tsconfig.json", "src/**/*.ts", "!src/**/*.test.ts"],

    tests: ["src/**/*.test.ts"],

    env: {
      type: "node",
      runner: "node"
    },

    testFramework: "jest"
  };
};

Jest configuration (in package.json)

{
  "jest": {
    "transform": {
      ".(ts|tsx)": "<rootDir>/node_modules/ts-jest/preprocessor.js"
    },
    "testRegex": "(/__tests__/.*|\\.(test|spec))\\.(ts|tsx)$",
    "moduleFileExtensions": [
      "ts",
      "tsx",
      "js"
    ]
  }
}

Code editor or IDE name and version

Visual Studio Code v1.14.0

OS name and version

macOS 10.12.5

Thanks for the repo!
The issue is fixed in the the latest core version and the fix is published. Note that after the update you'll still need the preprocessor configure similar to the issue that you have referenced (#1181 (comment)). I have sent you the pull request with the change.
