Handle 'no-unused-expressions' violations due to use of Chai expect

Using a Chai expect expression in a test with the StandardJS ESLint config will throw the ESLint error:

error  Expected an assignment or function call and instead saw an expression  no-unused-expressions

Since Chai is bundled with Cypress I think it only makes sense that eslint-plugin-cypress handle this without the user having to install a separate plugin to handle Chai expressions.

Eslint decided to not address this issue as it is library specific. It seems that the best fix for this would be to add the eslint-plugin-chai-friendly plugin to our eslint config or some similar configuration to ignore chai’s no-unused-expressions. @chrisbreiding thoughts?

Sure:

const onRequest = ({ request }) => {
  expect(request.body.email.billingUpdate).to.be.true
  expect(request.body.phone.documentUpdate).to.be.false
}
