Transaction Scripting Reference
This article contains a reference of all namespaces, classes, modules and methods that are available for creating transaction tests.
Hover over a keyword or method name in a script to see additional information, in both the ThousandEyes Recorder and the ThousandEyes platform on the test creation page.
For quicker orientation, there is a comprehensive collection of script examples provided by the transaction scripting examples repository in the ThousandEyes GitHub account.
Use
test to work with the ThousandEyes transaction test configuration, such as getting the target test URL (for example https://google.com/) or getting the test timeout setting.Namespace | thousandeyes |
Module | test |
Import Syntax | import { test } from 'thousandeyes' |
Used Like | const settings = test.getSettings(); |
Method | getSettings() |
Description | Returns an object with the current settings of the test. |
Parameters | None |
Returns | (object) with the following parameters: interval (number), timeout (number), url (string) and proxy (object). |
import { By, Key, until } from 'selenium-webdriver';
import { driver, markers, credentials, downloads, transaction, authentication, test } from 'thousandeyes';
runScript();
async function runScript() {
const settings = test.getSettings();
// Load page
await driver.get(settings.url);
await driver.takeScreenshot();
// Search
markers.start('SearchForWebdriver');
await driver.findElement(By.name('q')).sendKeys('webdriver', Key.RETURN);
await driver.takeScreenshot();
markers.stop('SearchForWebdriver');
// Wait for full page load
await driver.wait(until.titleIs('webdriver - Google Search'), 1000);
await driver.takeScreenshot();
};
This snippet shows how to get the test timeout setting and set the implicit timeout in the transaction to half that value. On the ThousandEyes platform, this test timeout setting is found on the Advanced Settings tab for the transaction test you’re working with, on the Cloud & Enterprise Agents > Test Settings screen.
Why would you want to do this? The implicit timeout is the time that each transaction step will wait for a designated page element to appear before timing out. By default, the ThousandEyes Recorder sets the implicit step timeout value to 7 seconds. This per-step value may need to be increased for tests that take longer to complete.
Instead of statically increasing the implicit timeout value in the script, you can configure it to be a proportion (for example 50%) of the total test timeout value. This will ensure the implicit timeout value is always set to a reasonable value, regardless of the test timeout setting.
import { By, Key } from 'selenium-webdriver';
import { driver, test } from 'thousandeyes';
runScript();
async function runScript() {
await configureDriver();
const settings = test.getSettings();
// Load page
await driver.get(settings.url);
}
async function configureDriver() {
const settings = test.getSettings()
await driver.manage().setTimeouts({
implicit: settings.timeout/2 * 1000
});
}

ThousandEyes transactions support two types of measuring time:
- Markers
- Overall transaction time
Markers are custom time delimiters, enabling precise time measurements of smaller sections of the transaction. A maximum of 200 markers can be defined in a transaction script. The Waterfall tab displays the first ten markers, with a Show more link if more than ten markers are defined.
Start a marker:
Namespace | thousandeyes |
Module | markers |
Method | start( markerName ) |
Description | Starts a marker with the supplied name. This marker can later be stopped by calling the stop function with the same name. |
Parameters | markerName (string) The name of the marker |
Returns | None. Will throw an error if attempting to start a previously started marker. |
Stop a marker:
Namespace | thousandeyes |
Module | markers |
Method | stop( markerName ) |
Description | Stops the marker matching the supplied name. |
Parameters | markerName (string) The name of the marker |
Returns | None. Will throw an error if attempting to stop a marker that hasn't been started yet or one that was already stopped. |
Set a marker:
Namespace | thousandeyes |
Module | markers |
Method | set( markerName ) |
Description | Creates a marker that spans from transaction start time to the time this method is called. Calling set implicitly closes the marker, so there is no need to later close it. |
Parameters | markerName (string) The name of the marker |
Returns | None. |
Running a transaction test implicitly causes the overall transaction time measurement, spanning from the moment the transaction test run starts and to the end of the transaction. However, if customization of overall transaction time's start and stop moments is required, the following methods can be used to such effect. |
Set the overall transaction time start moment:
Namespace | thousandeyes |
Module | transaction |
Method | start() |
Description | Sets the start time of the transaction. If not called, the transaction start time will default to the script start time. |
Parameters | None |
Returns | None |
Set the overall transaction time end moment:
Namespace | thousandeyes |
Module | transaction |
Method | stop() |
Description | Sets the end time of the transaction. If not called, the transaction start time will default to the script end time. |
Parameters | None |
Returns | None |
Provided is a set of mechanisms dedicated to locating elements on the page.
Namespace | selenium-webdriver |
Class | By |
Import Syntax | import { By } from 'selenium-webdriver'; |
Used Like | await driver.findElement(By.css('#myId')); |
Supported static methods | By.className( name ) |
| By.css( selector ) |
| By.id( selector ) |
| By.js( script, ...var_args ) |
| By.linkText( text ) |
| By.name( name ) |
| By.partialLinkText( text ) |
| By.xpath( xpath ) |
Reference | https://selenium.dev/selenium/docs/api/javascript/module/selenium-webdriver/lib/by_exports_By.html |

Use the
authentication module to get a time-based one-time password (TOTP) for 2-factor authentication, as in this scripting example: usingTOTPTwoFactorAuth.js.Namespace | thousandeyes |
Module | authentication |
Import Syntax | import { authentication } from 'thousandeyes' |
Used Like | var totp = authentication.getTimeBasedOneTimePassword(secretToken); |
Method | getTimeBasedOneTimePassword( secretToken ) |
Description | Generates a 6-digit temporary authentication code to be used in conjunction with a password on sites that support 2 factor authentication with time-based one-time passwords (TOTPs). |
