Cypress testing has stopped working

[mturnwall]

Current behavior:

On my local machine no tests are working at all. This includes the Cypress example tests. The browser opens for the test runner when clicking on a test spec but the browser remains a blank page. If I go onto my personal VPN everything works as expected.

This happens from both running it using the UI runner (cypress open) as well as running in the terminal (cypress run)

The strange thing is everything was running just fine about a month ago. I moved onto different features on the project I'm working on. I came back to working on writing test cases and things just stopped working. I even created a new branch and did a clean install of Cypress

Desired behavior:

Test should run as expected.

Steps to reproduce: (app code and test code)

Just run any example test spec such as viewport.spec.js

Here is some logging. Let me know if you need more logging information:

I've been able to isolate this to my actual machine. I've tried running Cypress on other machines here at work and tests run as expected.

I tried running Cypress on the Chrome version you specified - that works fine for me. I ran it on MacOS 10.13.6, which is different from yours.

These errors look notable:

status: 500, 
error: 'Error: getaddrinfo ENOTFOUND falozzfp falozzfp:80\n    
at errnoException (dns.js:50:10)\n    
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:92:26)\n' } +0ms

Are you behind a corporate proxy? Handling proxies will be better as soon as 3.3.0 is released, but you may require a workaround today. See #1469

[mturnwall]

No proxy that I know of. I’ve tried it on other machines on the same network and everything works as expected. It seems like the issue is with my individual laptop. When I’m back in the office I’m going to try logging into my work account in a different machine to eliminate the issue with my work directory account.

I logged into the guest account on my mac. Setup Cypress and am getting the same results, tests don't run. I'm not sure what on my machine could be causing it. Would be great if someone else with macOS 10.14.4 could test that Cypress runs correctly.

[Lakitna]

Cypress listens to some environment variables. Could those be the culprit here?

[debone]

I'm having the same issue, with the blank screen and the __ in the URL. I'm on MacOS 10.14.3 and Cypress 3.1.0

[debone]

Ok, I got it fixed. I think it was my mistake. I had a global version and a local version. I uninstalled my global and updated the local one to 3.2.0.

Running OSX 10.14.5 (18F132) - Updated last week. Now cypress DOM before and after tracking is no longer available. Test Runner fires tests properly but no before and after of the actions listed in the app view and no highlighting or clicking representation in the APP View window either. Upgraded to Cypress 3.3.2 and still exhibiting the same behavior.

I am using cypress 4.0.2. I am behind the company proxy. all proxies declared in env variables. Still, I get this error.

Unfortunately we have to close this issue due to inactivity. Please comment if there is new information to provide concerning the original issue and we can reopen.

This is most likely a network issue and not with Cypress. I'm running into this as well when I'm on my companies network while its working like a charm at home or if I use mobile hotspot.
