Stryker: Jest rootDir is ignored/replaced

[michael42]

Summary

When setting a custom rootDir (i.e. src) in the jest.config.js, Stryker seems to override it with the sandbox root path (ignoring the value from jest.config.js). This causes files not be found (because the src/ prefix is missing).

Module tests/setup.ts in the setupFiles option was not found.
       <rootDir> is: [...]/.stryker-tmp/sandbox3026627        // <- should have been [...]/.stryker-tmp/sandbox3026627/src

Stryker config

module.exports = function (config) {
  config.set({
    mutate: ['src/**/*.ts', '!src/**/*.spec.ts'],
    mutator: 'vue',
    testRunner: 'jest',
    reporters: ['progress', 'clear-text', 'html'],
    coverageAnalysis: 'off'
  });
};

Test runner config

jest.config.js:

module.exports = {
  globals: {
    'ts-jest': {
      babelConfig: false,
      tsConfig: {target: 'es2017'},
      diagnostics: { pathRegex: '/\.(spec|test)\.ts$/' }
    },
  },
  rootDir: 'src',
  testMatch: [
    '**/__tests__/**/*.ts?(x)',
    '**/?(*.)spec.ts?(x)'
  ],
  setupFiles: ['tests/setup.ts'],
  setupFilesAfterEnv: ['tests/setupScript.ts'],
  moduleFileExtensions: [
    'ts',
    'tsx',
    'js',
    'jsx',
    'json',
    'vue'
  ],
  transform: {
    '^.+\\.vue$': 'vue-jest',
    '^.+\\.tsx?$': 'ts-jest',
    '.+\\.(css|styl|less|sass|scss)$': 'jest-transform-stub',
  },
};

Minimal repository demonstating the issue with stryker 4.0.0: https://github.com/michael42/stryker-issue-1847

[kmdrGroch]

@michael42 try

module.exports = function (config) {
  config.set({
    mutate: ['src/**/*.ts', '!src/**/*.spec.ts'],
    mutator: 'vue',
    testRunner: 'jest',
    reporters: ['progress', 'clear-text', 'html'],
    coverageAnalysis: 'off',
   jest: {
      rootDir: 'src'
   }
  });
};

Running into this same issue today.

@kmdrGroch It appears that when I add that, my jest.config's testEnvironment: '\/myFolder' path still does not respect 'src' being the root dir. :(

[ghost]

I can't tell if this is related: https://github.com/facebook/jest/issues/8520#issuecomment-498435066

[ghost]

My solution was to just avoid using \ in my jest.config :/

[kmdrGroch]

Yes, it is specifically issue with Jest, we have had problems with it. So now please hang on and try these workarounds. We have this issue on top of our heads and we will be working on it as soon as we can.
For now I would ask for closing this one since #2163 is a summary of all these jest folder issues :)

[kmdrGroch]

Is this issue solved? Or can it be closed?

[michael42]

Seems to be still broken with stryker 4.0.0, here's a more minimal reproduction. Running jest works fine, but stryker run fails to run the setupFiles, setupFilesAfterEnv and additionally tries to run tests outside of the rootDir. Setting jest: { rootDir: 'src' } in the stryker.conf.js isn't allowed by the OptionsValidator.
