ERR_FAILED (-2) when loading new window Electron 102 (headless) via CLI

[MvRiele]

Current behavior

Test uses cy.window().then(win => { cy.spy(win, 'open').as('windowOpen'); }); and cy.waitUntil(() => cy.get('@windowOpen').should('be.called')); to check if opening a window is triggered.

When running in CLI Electron 102 (headless) an error is given:

ERR_FAILED (-2) loading 'https://www.testcode.com/?title=test' Error: ERR_FAILED (-2) loading 'https://www.testcode.com/?title=test' at rejectAndCleanup (node:electron/js2c/browser_init:161:7647) at EventEmitter.stopLoadingListener (node:electron/js2c/browser_init:161:8022) at EventEmitter.emit (node:events:526:28) at EventEmitter.emit (node:domain:475:12)

When i run in chrome, there is no error and the test runs fine

Desired behavior

No error given

Test code to reproduce

Test uses cy.window().then(win => { cy.spy(win, 'open').as('windowOpen'); }); and cy.waitUntil(() => cy.get('@windowOpen').should('be.called')); to check if opening a window is triggered.

We recommend stubbing window.open rather than spying on it as we don't support running Cypress commands inside another window (popup or new tab), see comment. So you can replace the cy.spy with cy.stub and you should be able to verify that the stub was called.

That said, Cypress should not be crashing when you call this function and we should print a nice error message in the UI in this case. I was able to reproduce this error with the code snippets you provided. Thanks for the issue @MvRiele, let me know if the workaround works for you.

we are experiencing this same error with electron (apparently not chrome) on a simple

cy.get("#foo").click();
cy.url().should('includ','http://bar');

when the thing being clicked causes a pop-up window to download a pdf

I'll leave this here, we are also experiencing this issue. By using cy.stub instead of cy.spy worked fine.
Although this should be marked as a bug, as it should not crash, it happend on Electron (headless) 106

An example on how you can test the window by stubbing:

const stub = cy.stub().as('open')
cy.on('window:before:load', (win) => {
            cy.stub(win, 'open').callsFake(stub)
})

And then to verify it got called cy.get("@open").should("be.called")

Damn it, I showed up, and I don't know how to fix it, okay

@benfenglee and everyone else coming here from google.

We had a similar issue, cypress simply crashed on startup with a similar message. It seems like cypress has problems when the computer is set to enery saving mode (Windows 11).

Perhaps the startup takes to long an cypress decides to kill the electron process.
