Parse threshold information from jest configuration in 'package.json'

Idea

Action should parse threshold information not only from jest.config.* files, but also from package.json.

Description

The schema of jest configuration in package.json file is described here

Additional context

Originally described in #223 issue.

@grahammcculloch,

Sorry, I just now realized how vague this issue is. This issue is not about parsing jest configuration, it is about taking threshold information from the jest configuration, because action should show clear message, when threshold values are not met.

This action don’t use any jest configuration to actually run tests, it simply runs the script, which is specified as test-script input (here is the docs link). So if jest not takes information from package.json file, it is most likely that something is wrong with your test-script option.

I’m glad this has been suggested as it’s a problem I’m encountering. Specifically, in my case, the config in package.json is for a Create React App:

{
  "jest": {
    "watchPathIgnorePatterns": [
      "<rootDir>\\/src\\/(.+\\/)+.+\\.stories\\.tsx"
    ],
    "collectCoverageFrom": [
      "<rootDir>/src/pages/**/*.+(ts|tsx|js)",
      "<rootDir>/src/components/**/*.+(ts|tsx|js)",
      "!<rootDir>/src/**/*.style.+(tsx)",
      "!<rootDir>/src/**/*.stories.+(tsx)",
      "!<rootDir>/src/**/*.index.+(tsx)"
    ],
    "coverageReporters": [
      "text",
      "text-summary"
    ]
  }
}
