Troubleshooting

Running ts-jest on CI tools

PROBLEM

Cannot find module "" from ""

SOLUTION

Check if rootDir is referenced correctly. If not add this on your existing jest configuration.

module.exports = {
  ...
   roots: ["<rootDir>"]
}

Check if module directories are included on your jest configuration. If not add this on your existing jest configuration.

module.exports = {
  ...
  moduleDirectories: ["node_modules","<module-directory>"],
  modulePaths: ["<path-of-module>"],
}

Check if module name is properly mapped and can be referenced by jest. If not, you can define moduleNameMapper for your jest configuration.

module.exports = {
  ...
  moduleNameMapper: {
    "<import-path>": "<rootDir>/<real-physical-path>",
  },
}

Check github folder names if its identical to you local folder names. Sometimes github never updates your folder names even if you rename it locally. If this happens rename your folders via github or use this command git mv <source> <destination> and commit changes.
