This document describes scripted browser functions available for synthetic monitors versions 0.5.0 or 0.6.0. If you are using a newer monitor version, see the monitor version Chrome 100 and newer documentation. If you are using older monitor versions, see the monitor version 0.4.0 and lower documentation.
For more on monitor versions and runtime differences, see Runtime environments.
重要
As of August 26, 2024, you can no longer create new monitors using legacy runtimes on public or private locations. On October 22, 2024, we will end of life the containerized private minion (CPM) and legacy synthetics runtime versions.
For public locations, use the runtime upgrade UI to update your monitors to the newest runtimes.
For private locations, please review our recommended migration steps to avoid monitor degradation.
The Chrome 100+ browser runtime provides backward compatible support for 0.5.0 and 0.6.0 browser runtime syntax.
For some common usage examples, see Introduction to scripted browser monitors.
Selenium Webdriver APIs
By using the variables $driver and $browser, your scripted browsers get access to Selenium Webdriver APIs 3.6.0 for monitor version 0.6.x and Selenium Webdriver APIs 3.5.0 for monitor version 0.5.x.
In particular:
$driverprovides all the exports from theselenium-webdrivermodule (for example,ActionSequence,Button,By,WebElement, etc.).$browseris a synthetic monitoring instance ofselenium-webdriver.WebDriver(). It exposes the main basicWebDriverAPIs likeget()andfindElement(), as well as some synthetic custom APIs.
Top-level functions: Build your script
New Relic calls top-level functions directly from your $browser instance. These provide a wide range of functionality that covers many basic scriptable actions.

Setting the wait timeout to Be careful increasing the wait timeout, as it will increase test run time, especially with slower location strategies like XPath. Default is 10 seconds. Return value: promise |
| Sets the amount of time to wait for a page load to complete before returning an error. If the timeout is negative, page loads may last up to 180 seconds. Default is 60 seconds. Return value: promise |

Locators: Find page elements
Locators are a collection of factory functions for creating locator instances. Locators find DOM elements, which can be passed to functions such as $browser.findElement. Call them through $driver.By.
Function | Description |

| Locates elements matching a XPath selector. Return value: locator |
WebElement: Interact with page elements
When a function such as $browser.findElement or $browser.waitForAndFindElement returns a WebElement reference, these functions can be used to interact with that element. For example, you can click on buttons, sent text to form inputs, and get attributes of elements to test.
Function | Description |
|---|---|

ActionSequence: Link multiple actions
Action sequences can create complex user interactions with your website.
- To create a new action sequence, use
$browser.actions(). - To link multiple actions together into a sequence, include
perform()after each. This executes and then terminates individual sequences, including single-action sequences.
The following table contains a list of available actions. For more information, see the WebDriver ActionSequence documentation on GitHub.
Function | Description |
|---|---|
| Clicks a mouse button. If an element is provided, the mouse will first be moved to the center of that element. This is equivalent to Return value: actionsequence |
| Double-clicks a mouse button. If an element is provided, the mouse will first be moved to the center of that element. Return value: actionsequence |
| Convenience function for performing a drag and drop maneuver. The target element may be moved to the location of another element, or by an offset (in pixels). The location is an object with two properties Return value: actionsequence |
| Performs a modifier key press. Must be one of Return value: actionsequence |
| Performs a modifier key release. The release is targeted at the currently focused element. Return value: actionsequence |
| Presses a mouse button. The mouse button will not be released until Return value: actionsequence |
| Releases a mouse button. Behavior is undefined for calling this function without a previous call to Return value: actionsequence |
| Moves the mouse. The location to move to may be specified in terms of the mouse's current location, an offset relative to the top-left corner of an element, or an element (in which case the middle of the element is used). Return value: actionsequence |
| Executes this action sequence. Return value: promise |
| Simulates typing multiple keys. Each modifier key encountered in the sequence will not be released until it is encountered again. All key events will be targeted at the currently focused element. For a full list of supported non-alphanumeric keys, see the WebDriver enum key documentation on GitHub. Return value: actionsequence |
Promises: Link actions into sequences
You can also execute functions directly on promises. Synthetic monitoring is a native Node.js environment and uses standard Node.js promises.
These functions evaluate the status of promises, cancel them, and more. In particular, you can create sequences of actions with the then() function and its siblings, finally() and catch(). For more information, see Sequence actions.
Function | Description |
|---|---|
| Whether this promise's value is still being computed. Return value: boolean |
| Registers listeners for when this instance is resolved. This is the basic function used to link synchronous actions in your script. Return value: promise |
| Registers a listener to invoke when this promise is resolved, regardless of whether the promise's value was successfully computed. Return value: promise |
| Registers a listener for when this promise is rejected. Return value: promise |
Navigate: Move through browser history
The $browser.navigate() function exposes a number of functions that allow you to move backwards and forwards through your browser history, refresh your page and navigate to new pages.
Function | Description |
|---|---|
| Move back by one step in the browser's history. Return value: void |
| Move forward by one step in the browser's history. Return value: void |
| Refresh the current page. Return value: void |
| Load a new webpage in the current browser window. Return value: void |
Conditions: Pause and wait for conditions
