Current behavior

I have an email form input field which displays a (real-time) error message beneath if invalid input is detected, to the effect of:
"[value] is not a valid email"

I use Cypress to run a lot of simultaneous checks (i.e. make sure the form is disabled, there's an error indicator somewhere on the page, the text is red, etc, etc, etc). Somewhere along the way, Cypress also checks that the error message itself contains the input the user entered... and this is where it falls over.

I've provided the smallest sample code I could make which reproduced the problem consistently

The error stack trace is as follows:

Error: Timed out retrying after 15000ms: Syntax error, unrecognized expression: :contains('\"<OE_D]dQ\'), [type='submit'][value~='\"<OE_D]dQ\']

NB: despite the appearance in the screenshot, there is definitely a backslash at the end of the problematic string. Cypress is also parsing error messages so this is why it's being hidden (see #18800 for how this affects other text formatting)

Desired behavior

Not encounter an error... and confirm whether the selected element contains the text or not

Test code to reproduce

const nastyString = '"<OE_D]dQ\\'
const tag = Cypress.$('<span />').text(nastyString).appendTo(document.body)
cy.wrap(tag).should('contain', nastyString) // fails here

// cy.wrap(v).should('contain', nastyString.replace('\\', '\\\\')) // this succeeds

Cypress Version



Platform: Win 11
Node: 17.1 (nodeVersion: bundled - it'll crash otherwise, see #18914 )

Sorry for the late reply.

Confirmed that it doesn't work with the code below:

it('t', () => {
  const nastyString = '"<OE_D]dQ\\'
  const tag = Cypress.$('<span />').text(nastyString).appendTo(document.body)

  cy.wrap(tag).should('contain', nastyString) // fails here

The code for this is done in cypress-io/cypress#20704, but has yet to be released.
We'll update this issue and reference the changelog when it's released.
