When I try to use the babelrc plugin in cypress

const preprocessor = require('cypress-react-unit-test/plugins/babelrc')

module.exports = (on, config) => {
  preprocessor(on, config)
  // IMPORTANT to return the config object
  // with the any changed environment variables
  return config
  // `on` is used to hook into various events Cypress emits
  // `config` is the resolved Cypress config
}

I get the error

I get the same issue when adding the webpack loader via

    module.exports = (on, config) => {
      require('cypress-react-unit-test/plugins/load-webpack')(on, config)

       return config
    }

It looks like the issue is that I have not setup code coverage. Is it a requirement to setup code coverage to use the webpack or babel loader?

This is weird, I will keep this open, but this is nyc not loading correctly, I have released cypress-react-unit-test@4.16.1 to only load nyc when needed, thus if you disable code coverage, then at least it does not crash

anark commented

Very strange, that seems to fix the first issue, however it still shows TypeError: (0 , _schemaUtils.validate) is not a function if you try to run the test.

I've updated cypres-react-unit-test in the example app to show that error if you try to run the spec.

That fixes the terser issue.

Thanks!
