The module '../build/Release/magic' could not be located when running Jest tests in 'index.js'

Encountered the following error message while running jest tests:

Error: Unable to locate module '../build/Release/magic' in 'index.js'

  at Resolver.resolveModule (node_modules/jest-resolve/build/index.js:191:17)
  at Object.<anonymous> (node_modules/mmmagic/lib/index.js:3:13)

The application runs normally without any issues, but Jest tests throw the above error. Has anyone faced a similar issue? Thank you.

NodeJS version: 8.11,

Default configuration set to: 'Release'

Answer №1

In the magical world of build/Resolve/magic, there lies a file named magic.node, however Jest has certain rules when it comes to importing files - they must have extensions specified in moduleFileExtensions. The solution is simple: just add node to moduleFileExtensions:

"moduleFileExtensions": [
    "js",
    "json",
    "ts",
    "node"
],
