The document discusses using the STOPWATCH command in iMacros to perform performance testing and internet monitoring. It provides details on how to insert the STOPWATCH command to measure response times at different points on a webpage. Sample output data from the STOPWATCH command running a demo macro is also shown. Best practices for response time measurements using iMacros are outlined.

1. Performance Testing & Internet Monitoring

2. STOPWATCH Command Intended for: Performance testing (Response time measurements) Internet Monitoring Why?: Response time is a top factor for most visitors in choosing a website. For many visitors response time is even more important than prices or quality of content. Monitor server uptime and server load Notify webmaster in case of problems

6. Best Practice for Response Time Measurements iMacros response time measurements always reflects the true user experience as they are measured using a real browser and the original browser plug-ins such as Adobe Flash Player, Silverlight or SUN Java runtime. Add a CLEAR statement to your macro. Average Measurements. The &quot;internet speed&quot; can fluctuate from minute to minute even on a fast connection. Accuracy depends on the accuracy of the PC clock. This applies to all software that does time measurements on a PC. Under normal conditions the processor speed does not influence the measured response times. Only if the PC is so slow that the web page rendering of the browser is slowed down, will the CPU speed have an influence on the measured response time.

7. Keyword Assertion Search for a keyword can be done via TAG Create a macro with only two lines: VERSION BUILD=6120125 TAG POS=1 TYPE=B ATTR=TXT : * completed * In this example, we are searching the web page for the first occurrence (POS=1) of the keyword &quot;completed“. The TAG command will test if keyword appeared on website.

8. Image Assertion Search for an image can be done via the SAVEITEM feature: CLEAR URL GOTO=http://www.iopus.com/imacros/ TAG POS=1 TYPE=IMG ATTR=TXT:Only*version CONTENT=EVENT:SAVEITEM This macro will download an image. If the image is missing on your web page, the macro stops with an “Image not found&quot; error. To make sure that the missing image is not stored in the browser cache, it is recommended that you use the CLEAR command before this test.

9. Demo: Internet Monitoring Part1: Record an “Online Shopping Experience” macro at “Sears.com” and use it for response time measurements. Measure response time at various critical points separately, for example when an item is placed into the shopping cart. Part 2: Make sure the price is displayed correctly Part 3: Make sure the item image is displayed correctly
