NO_PROXY ignored when baseUrl is set

[skydever]

Current behavior:

I am behind a corporate proxy and want to test against an internal URL, no proxy should be used. To do so I added the host of the baseUrl to the environment variable NO_PROXY and no_proxy (I also have HTTP_PROXY, http_proxy, HTTPS_PROXY and https_proxy set up, pointing to the corporate proxy).

When I run cypress I get the error:

Cypress could not verify that this server is running:

  > https://<my-domain>/<context-root>/

We are verifying this server because it has been configured as your `baseUrl`.

Cypress automatically waits until your server is accessible before running tests.

We will try connecting to it 3 more times...
We will try connecting to it 2 more times...
We will try connecting to it 1 more time...

Cypress failed to verify that your server is running.

Please start this server and then run Cypress again.

When I remove all the proxy env. variables everything is working.

Desired behavior:

NO_PROXY should be considered.

Steps to reproduce: (app code and test code)

Set env. variables HTTP_PROXY + HTTPS_PROXY to a valid proxy.
Set the domain of the baseUrl as value for the env. variable NO_PROXY.
Run the tests.

Versions

Cypress: 3.3.1
OS: Windows 7 Enterprise
Running with the included Electron client

Prior Cypress 3.3.1/3.3.0 I had no issues concerning proxies.

Thank you a lot, Cypress is awesome!!

[flotwig]

Yeah, in Cypress 3.3.0 we added first-class support for proxies; unfortunately, this means that some new bugs are cropping up.

I'm able to reproduce this behavior for HTTPS baseurls only, looking in to a fix now.

[skydever]

thx a lot! 👍

[cypress-bot]

The code for this is done in cypress-io/cypress#4309, but has yet to be released.
We'll update this issue and reference the changelog when it's released.

[cypress-bot]

Released in 3.3.2.
