Record User Actions 1. Create a new Vuser script. 2. Select Web(HTTP/HTML) protocol to record against browser-based applications. 3. Set Recording Options. 4. Start Recording. 5. Enter URL of the application under test & click OK. 6. Perform user steps with Web application. 7. Click Stop Recording once all the users steps have been recorded. 8. Save the script. 13

Which Run-time Settings Apply to Web Play Back? DEMO – Run-time Settings 16 § Run Logic § Pacing § Log § Think Time § Miscellaneous § Speed Simulation § Browser Emulation § Proxy § Preferences § Content. Check Available for all protocols. Specific to Web.

Run-time Settings – Run Logic Iteration Count: Set Number of Iterations to more than one to iterate the steps recorded under ‘Action’ section. 17

Run-time Settings - Pacing Start new Iteration: These settings are more useful when load testing. For debugging purposes, use the default values. 18

Run-time Settings - Log Use defaults for this stage of scripting, later we will see when to use other log options. 19

Run-time Settings – Think Time Use the default values at this stage of scripting. 20

Run-time Settings – Miscellaneous when running the script in Vu. Gen, uncheck this option. Multithreading and Automatic Transactions only apply when the script is run as a part of load test. 21

Run-time Settings – Speed Simulation Network Speed: When in script development stage, it is not important to emulate different connections like modem, DSL and cable to see application performance. If required, select the various options to simulate users connecting at different speeds. 22

Run-time Settings – Browser Emulation Simulate browser cache: Check this option to ensure normal browser behavior at real-user level Download non-HTML resources: Check this to download resources like Java. Script, applet or Active X components 23 Simulate a new user each iteration: Use this option to reset browser context on each iteration

Run-time Settings – Proxy It is recommended to use the same proxy settings used during recording. 24

Run-time Settings – Preferences Enable Checks. Enable all the options under ‘Generate Web performance graphs’ in the Controller so that the graphs can be viewed during analysis. At this stage of script development, use the default settings under ‘Advanced. ’ 25

Run-time Settings – Content. Check options: Allows you to add rules that globally predefine errors to detect errors in the server response. 26

Also Set General Options Under General Options, set Replay, Environment, Display and Correlation tab settings before playing back the script. DEMO – General Options 27

Running the Script Click the Run button to play back the script. The Execution log lists all messages once the script has stopped running. DEMO – Running a script and how to set results directory 28
