Redirect adds __ within directory path when experimentalSourceRewriting is on

Current behavior:

Current behavior:
When I login through the normal browser then I am able to log in.
But when running from cypress test runner the directory path is missing from URL.

The Cypress Test Runner redirects to: http://:8084/__/branchHome.html

I have added below after there was a comment on my previous same bug still it didn't worked.

The previous bug raised: #5569

My cypress.json file:

Desired behavior:

The Cypress Test Runner should redirect to : http://:8084//branchHome.html

Test code to reproduce

Below is the code:

cy.visit("http://<ip>:8084/<directory>")
cy.get("#login").click()
cy.get("input[value='Organization']").click()
cy.get("#username").type('<User name provided>')
cy.get("#pwd").type('<password provided>')
cy.get("#login").click()

@varunpradhan Thanks for opening an issue.

Do you have any idea what in your application initiates the redirect to the branchHome page? Typically we've seen this issue when the application under test is changing the route in some manual way. Some previous examples were:

• Setting location, location.href, calling location.replace, location.assign
• Calling window.top or window.parent
• Calling into window.frames, window.parent.frames or other frames
• Having an integrity attribute on script resources.

[varunpradhan]

@jennifer-shehane yes it uses location.href

I think this might be happening because the current version of experimentalNetworkStubbing only works on JS served from the current origin. JS served from other origins is not yet intercepted.

Is the script that does the location.href change served from the same domain that you originally cy.visited?

[varunpradhan]

@flotwig yes it is from the same domain.

[flotwig]

Can you share the source code that is doing the location.href change please?

[varunpradhan]

@flotwig Below is the source code that is doing the location.href change:

function navigate(url) {
  try {
    window.location.href = url;
  } catch (e) {
    alert(e + "url===>" + url);
  }
}

We are using a relative URL.
Can anyone also suggest what approach in source code will work my cypress test? I will pass on the feedback to my developers.

[flotwig]

@varunpradhan the issue occurs when setting href to a relative path, so if you could use an absolute URL instead of relative, that would avoid the bug

[varunpradhan]

@flotwig I have forwarded the feedback to development team. Thank you for the suggestion. But I don't think they will change this anytime soon.
Till that time will be waiting for this bug to be resolved.

We're seeing the same. Are there any other workarounds? For us the setting of location.href is inside a framework so it's not something we can update. Unfortunately this means that Cypress just won't work for a large part of our site.

@flotwig does this mean code served via cdn won't be intercepted? For example if we visit alpha.zenefits.com and our js is served via cdn.zenefits.com it's not expected to work?

I think this might be happening because the current version of experimentalNetworkStubbing only works on JS served from the current origin. JS served from other origins is not yet intercepted.

Is there any timeline on when these redirecting to __ issues will be addressed? It's causing us significant pain and means we can't write tests for a number of high traffic areas of our app. Would be great to know if this is on the roadmap as we plan our future usage of Cypress.

[cypress-bot]

The code for this is done in cypress-io/cypress#15995, but has yet to be released.
We'll update this issue and reference the changelog when it's released.

[cypress-bot]

Released in 7.3.0.
