Replay a user flow

After recording a user flow, you can replay it by clicking on the ReplayReplay button.

You can see the user flow replay on the page. The replay progress is shown in the Recorder panel as well.

Gotchas

When replaying a user flow recording, the Recorder waits until the element is visible or clickable in the viewport or tries to automatically scroll the element into the viewport before replaying the corresponding step.

You can simulate a slow network connection by configuring the Replay settings. For example, expand the Replay settings, select Slow 3G in the Network drop-down. replay settings

More settings might be supported in the future. Share with us the replay settings you would like to have!

Measure a user flow

You can measure the performance of a user flow by clicking on the Measure performance button. For example, checkout is a critical user flow of a shopping website. With the Recorder panel, you can record the checkout flow once and measure it regularly.

Clicking on the Measure performance button will first trigger a replay of the user flow, then open the performance trace in the Performance panel.

Learn how to analyze your page's runtime performance with the Performance panel. You can enable the Web Vitals checkbox in the Performance panel, to view the Web Vitals metrics, identify opportunities to improve your user browsing experience.

Edit steps

Let's walk through the basic options to edit the steps within the recorded workflow.

For a comprehensive list of editing options, see Edit steps in features reference.

Expand steps

Expand each step to see the details of the action. For example, expand the Click Element "Cappuccino" step.

In the recorder panel, the Cappuccino element has been expanded to reveal type, target, selectors, offset X, and offset Y.

The step above shows two selectors. For more information, see Understand the recording's selector.

When replaying the user flow, the Recorder tries to query the element with one of the selectors by sequence. For example, if the Recorder successfully queries the element with the first selector, it will skip the second selector and proceed to the next step.

Add and remove selectors from a step

You can add or remove any selectors. For example, you can remove the selector #2 because just aria/Cappuccino is sufficient in this case. Hover over the selector #2 and click on - to remove it.

The DevTools recorder panel shows an option to remove a selector

Edit selectors in a step

The selector is editable too. For example, if you want to select Mocha instead of Cappuccino, you can:

  1. Edit the selector value to aria/Mocha instead.

    edit a selector

    Alternatively, click the SelectSelect button button and then click Mocha on the page.

  2. Replay the flow now, it should select Mocha instead of Cappuccino.

  3. Try to edit other step properties such as type, target, value and more.

Add and remove steps

There are options to add and remove steps too. This is useful if you want to add an extra step or remove an accidentally added step. Instead of re-recording the user flow, you can just edit it. Click on the 3-dot kebab menu next to the step to open the menu.

DevTools UI for coffee cart, including the menu for the Scroll event expanded to reveal three options: Add step before, add step after, and remove step.
  1. For example, the Scroll event after the Mocha step is not necessary. You can select Remove step to remove it.
  2. Say you want to wait until the 9 coffees display on the page before performing any steps.
  3. In the Mocha step menu, select Add step before. A new step named Assert Element was added and can now be edited
  4. In Assert Element, edit the new step with the following details:
    • type: waitForElement
