During task configuration, you will be prompted to adjust the following basic settings.


Enter the URL that you wish to test. The address should be formed exactly as you would use it in a browser, such as http://www.example.com. You must include the http:// or https:// at the beginning of the address.  You may include any GET parameters at the end of your URL.

Time Validation Threshold (in seconds)

Enter the number of seconds you expect your task should be completed in case you would like to receive an error if this threshold is exceeded.

Browser Type

Select the desired browser platform from the following choices: Edge, Firefox, Chrome, or a mobile device.

Depending upon which browser type you selected above, the Browser Version field will appear. Here you can specify a specific version of the browser you wish to use in the test.

Response Time Calculation

Response time is commonly considered as the time passed from the end-user request in a real browser to the particular event during the page loading process.

Choose from the following options to calculate Response Time for:

  • Full Page Load. Calculation of Full Page Load time is started when a site visitor initiates a request and stops when the entire page’s content is displayed in the browser window (the loading spinner has stopped spinning). To put it in another way, the time includes server response time and download time of all sub-resources like images and CSS (the Load Complete End event).
  • Network Times Only. Selecting Network Times Only is useful if you are interested in a pure server response and download time of the page elements, and not in how long it takes an arbitrary end-user machine to render the page. It still sends a browser agent of the type specified above – and the server may send a different response based upon the agent specified. The time between network requests (e.g., JavaScript was executing) is not taken into account during the network time calculation, so verification for completion timeout is applied to pure response time.
  • Navigation Timing Event. This option brings up a selection of particular time points in the page loading process. Some correspond to DOM events, others describe the time at which internal browser operations of interest took place. For descriptions of a particular event parameter, see https://www.w3.org/TR/navigation-timing/#sec-navigation-timing-interface.
  • Full Session Time. The time includes the Full Page Load time and User Delay time (by default we add a random delay between 3 and 6 seconds to simulate real user behavior).

Content Validation

Content Validation Keywords are used to ensure that the expected content was loaded onto a web page. In the Keyword fields, you can specify one or more words or phrases that you wish to search for in the web page content.  If the expected keywords are not found, the task will return an error.

You can enter multiple strings into the keyword fields.  The values you enter can be separated by logical expressions as follows:


{[ – keyword expression start;
]} – keyword expression end;
() – grouping brackets;
& – logical AND;
| – logical OR;
! – logical NOT;
“string” – a keyword.

A successful keyword expression must include the start and end brackets as follows:


Basic Authentication

The Basic Authentication scheme is used to allow users to access content on some websites. Once provided, login credentials will be passed along with the request header to the web server.

  • Username: contains a username for HTTP/S basic or digest access authentication.
  • User Password: contains a password for HTTP/S basic or digest access authentication.

Do not confuse Basic Authentication with other authentication schemes such as Bearer Authentication that involves bearer tokens and OAuth 2.0 that uses access tokens.

Read the articles on Basic Authentication Username and Password and Monitoring OAuth 2.0-based APIs for more information.

Download Filter 

Expand the network element filter section and add a filter rule to ignore certain elements, such as images, Flash, or CSS, so they are not downloaded. You can use this to filter out elements that return an error. For example, you could ignore files that end in .js, .css, or .png. Or you could ignore files that contain google or jquery, etc.

There are two types of rules:

  • Ignore elements corresponding to the mask.
  • Download only the elements that correspond to the mask.

Each “Download” and “Ignore” field has three possible values:

  • Start With. Each referenced object which starts with this string will be filtered.
  • Contain. Each referenced object which contains this string will be filtered.
  • End With. Each referenced object which ends with this string will be filtered.
  • Equals. Each referenced object which is equivalent to this string will be filtered.

Before applying, be sure that your root HTML element isn’t filtered.

Once the script has been created, you have to configure the stress test scenario.
