Determines if an element is present in the DOM.

isPresent() will automatically wait for the element to be present (until the specified timeout). If the element is not found, an error is thrown which will cause the test to fail. Starting with v1.2 you can suppress element not found errors by specifying the suppressNotFoundErrors option.

Usage:

.isPresent(selector, callback)
.isPresent(using, selector, callback)

Parameters:

Name Type description
using
Optional
string

The locator strategy to use. See W3C Webdriver - locator strategies

selector string|object

The selector (CSS/Xpath) used to locate the element. Can either be a string or an object which specifies element properties.

callback function

Callback function which is called with the result value.

Example:

module.exports = {
  demoTest(browser) {
    browser.isPresent('#main ul li a.first', function(result) {
      this.assert.equal(typeof result, "object");
      this.assert.equal(result.status, 0);
      this.assert.equal(result.value, true);
    });

    // with explicit locate strategy
    browser.isPresent('css selector', '#main ul li a.first');

    // with selector object - see https://nightwatchjs.org/guide#element-properties
    browser.isPresent({
      selector: '#main ul li a',
      index: 1,
    });

    browser.isPresent({
      selector: '#main ul li a.first',
      timeout: 2000 // overwrite the default timeout (in ms) to check if the element is present
    });
  },

  demoTestAsync: async function(browser) {
    const result = await browser.isPresent('#main ul li a.first');
    console.log('isPresent result', result);
  }
}
