contains() method returns partial last match #158

Given HTML fragment

  <li>bar foo</li>

then contains returns last element with partial match

cy.get('ul').contains('li', 'foo') 
// returns <li>bar foo</li>

It would be nice to prefer exact string match in case of multiple matches.
We also just wrote our own regular expression command for this case

function textCommand (subject, selector, regex) {
  if (!subject || !Cypress.Utils.hasElement(subject)) {
    subject = this.prop('withinSubject') || this.$$('body')

  if (typeof regex === 'string') {
    regex = new RegExp(regex)

  var log = Cypress.Log.command({
    name: 'text',
    message: ['finding text', selector, regex],
    $el: subject,
    onConsole: function () {
      return {
        Subject: subject,
        selector: selector,
        regex: regex

  const items = Array.from(subject.find(selector))
  const found = items.find((el) => regex.test(el.outerText))
  return found
// use like cy.get('.element').text('span', /foo$/)
Cypress.addDualCommand('text', textCommand)

Doing some preliminary testing, this is actually caused by you passing the li selector as the first argument. If you hypothetically only passed in the content without the selector this would work.

Okay I was able to fix both of your requests, however I don't think we'll opt into preferring "exact string matches" over partial matches.

In 0.16.2 the first <li> will be returned instead of the last. I'm not sure why we had code that was returning the last element when the selector was provided as an argument. After I removed that code all 70+ tests around cy.contains still passed. Must have been an oversight.

Additionally I was able to add in RegExp support without any performance problems. There could be some weird edge cases around this but I added a bunch of tests and they all pass.
