(Cypress) Make ELECTRON_EXTRA_LAUNCH_ARGS optional for local development #191
Description
Is your feature request related to a problem? Please describe.
There are cases while running cypress locally when there's no need to run chromatic nor to upload builds. Example:
- While debugging a CI failure
- While working on a new feature branch and locally running cypress
- Overall local development
However npx cypress run won't work and throw the error Error: Please provide a port number since ELECTRON_EXTRA_LAUNCH_ARGS is mandatory for the current chromatic plugin configuration.
Describe the solution you'd like
Been able to locally run npx cypress run without errors, knowing no snapshots will be taken. If ELECTRON_EXTRA_LAUNCH_ARGS is provided, that's the flag to make chromatic work, but it shouldn't just break local development and force us to pass ELECTRON_EXTRA_LAUNCH_ARGS even if we don't need snapshots.
Describe alternatives you've considered
Have tried adding a default value for process.env.ELECTRON_EXTRA_LAUNCH_ARGS = "--remote-debugging-port=9222" on cypress.config.ts but got this error err Error: connect ECONNREFUSED 127.0.0.1:9222
Also tried adding a new before:browser:launch event and passing the args there, but got the port error
Additional context
Created this as a feature request because everything works as expected when ELECTRON_EXTRA_LAUNCH_ARGS is passed as an environment variable, but would just like to not pass it, and run cypress as usual without chromatic snapshots.
