The current cypress config has a global eslint-disable:
typescript
```
/* eslint-disable import/no-extraneous-dependencies, global-require, arrow-body-style */
// const webpack = require('@cypress/webpack-preprocessor')
```
But this assumes that `eslint-import-plugin` is present, whereas this is only true when the selected preset is the Airbnb one.
In other cases, this fails `yarn lint` right away with:
```
error: Definition for rule 'import/no-extraneous-dependencies' was not found (import/no-extraneous-dependencies) at tests/e2e/plugins/index.js```
Even if using the Airbnb preset, the comment does not have any effect, as, by default, the `require` call is commented.
This commit now splits the rules disabling in two:
- one commented for the people using Airbnb and who will uncomment the require call below, as it is only useful for them.
- one activated that disables `arrow-body-style` as it will fail the linting for people using Airbnb preset with the current config.
* test: add cypress test for TS
* fix: remove webpack-preprocessor from cypress config
Removes the `@cypress/webpack-preprocessor` from the generated cypress configuration, as it leads to several issues regarding file watching, headless mode and TS support.
Fixes#2903
BREAKING CHANGE: `cli-plugin-unit-jest` and `cli-plugin-unit-mocha` now register
"test:unit" command and script instead of "test"; `cli-plugin-e2e-cypress` now
register "test:e2e" with optional `--headless` flag instead of "e2e" and
"e2e:open"; `cli-plugin-e2e-nightwatch` now register "test:e2e" instead of "e2e".
