Determines if an element is present in the DOM.

The command 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. You can suppress element not found errors by specifying the selector argument as an object and passing the suppressNotFoundErrors = true option.

For more info on working with DOM elements in Nightwatch, refer to the Finding & interacting with DOM Elements guide page.

Usage

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

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/writing-tests/finding-interacting-with-dom-elements.html#postdoc-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);
  }
}
