Unrecognized expression for regex that ends with /=\s+[0-6]/

[asartalo]

Current behavior

I have a cy.contains() call with the following:

cy.contains(/[56]\s+-\s+[0-6]\s+=\s+[0-6]/);

And it fails with:

Error: Syntax error, unrecognized expression: :cy-contains('/[56]\s+-\s+[0-6]\s+='\s+[0-6']/'), [type='submit'][value~='/[56]\s+-\s+[0-6]\s+='\s+[0-6']/']

It looks like there are extra single quotes? I'm not sure. The minimal code that throws the same error is:

cy.contains(/=\s+[0-6]/);

Desired behavior

Should not throw Error "Syntax error, unrecognized expression".

Thanks for opening an issue! I was able to reproduce this issue and it does appear to be a bug in how we are handling RegEx. It also seemed to fail with cy.contains(/=[0-6]/);

I tested with the code below.

<div>a=2</div>
<div>a</div>
<div>b</div>
<div>5 - 6 = 6</div>

it('t', () => {
  cy.visit('fixtures/a.html')
  cy.contains(/=[0-6]/).should('have.text', 'a=2')
  cy.contains(/[56]\s+-\s+[0-6]\s+=\s+[0-6]/)
})

It's working when there is text to find with = sign.

But when there is no element with =. it doesn't wait for it to appear, but to throw an error with the error message above.

At first, I thought the bug was about cy.contains() not working correctly. But it was showing wrong error message.

The problem is a bit hard to fix because Sizzle escapes attribute selector in the code below:

The code for this is done in cypress-io/cypress#21388, but has yet to be released.
We'll update this issue and reference the changelog when it's released.
