Coming soon, CloudTest and TouchTest will support bursts, helping you design a clip that mimics a browser's handling of Single Page App and Ajax type websites, where multiple resources are downloaded in parallel but there is no parent HTML document associated.

You can Add a Burst in CloudTest, just like any other container. All messages inside a Burst run simultaneously. However, Bursts support all containers, which run based on their own timing.

Bursts abide by a thread limit, allowing you to select how many messages run simultaneously, only running subsequent messages after the original ones are completed.

Some important notes on Bursts:

  • Default is 50 threads in the Clip Editor.
  • Maximum is 100 threads as a server setting.
  • Both thread limits are editable.
  • CloudTest will use the lower thread limit of the Clip Editor and Server settings.
  • When a Server setting limit is encountered, an error is visible in General Mode Results Detail.

Creating a Burst

To create a burst:

  1. Log into your CloudTest instance and open a new Clip.
  1. Open the container menu and select Add a Burst.

  1. Add message(s) by clicking the Messages/Actions, opening the bottom panel, which contains available targets and actions.

  1. In the bottom panel, you can edit message parameters like: URL values, query strings, validations, etc. To open and edit message parameters, double-click the message you want to edit.

  1. Edit the thread limit to select how many messages run simultaneously. Subsequent messages will only run after the original ones are completed. The default thread limit in the Clip Editor is 50 (the maximum thread limit is 100).

  1. When you're finished editing Bursts, click the Play option.

Viewing (and Interpreting) Results

After you click Play, the Result Details Dashboard will appear. You can check out details like Start Time and Response Time. Using the Waterfall Dashboard can help you visulalize the relationship between message response times.

To open the Waterfall Dashoard, hit the plus icon atop the Results Detail Dashboard and choose Waterfall Dashboard in the New Dashboard wizard.

The Waterfall Dashboard compares Response Time among messages and illustrates the thread limit grouping.

Note: The sequence messages appear in the Clip Editor may not be the sequence they run on.
