Figure 12-8. The WAS window with the recorded script 8. Click the Stop Recording button. The Recording window will close (although it won t cause the opened browser instance to close automatically). 9. The WAS tool will display the Scripts window. In it, you will see a new item named New Recorded Script. It s a good idea to change its name to something more meaningful. Change the script s name to FRSimpleAdminScript, as shown in Figure 12-9. 10. Set the Server field to the one hosting your Friends Reunion application. If you re hosting Friends Reunion on the same machine that is running WAS, you don t need to make a change here (localhost is the default). If you have different machines for the application and for WAS, type the application server name in the Server field. 11. Now you can clean up the script generated by WAS, so that it does not include any static content. You can do this by clicking the leftmost column of the desired row and then pressing the Delete key. For this test, you should delete all .gif and .css files, so that your list will end up looking similar to this (with just five items in it):

Figure 12-9. Your new script added to the WAS Scripts window 12. While still at the Scripts window, adjust a setting of your newly created script. Expand the script node and click the Settings child. Change the default Warmup time from 0 to 10 seconds, as shown in Figure 12-10. This will cause WAS to load-test your server 10 seconds before considering the test started, which will give your server some time to initialize itself in preparation for the test. So, for example, if the server needs to precompile any .aspx files, this one-time precompilation will not skew the test results.

How It Works You have just created your first WAS test script. It will play a crucial part in the Friends Reunion performance test you ll run in the next section. The script itself follows the steps that an administrator user of the application would usually perform at the beginning of a session: browsing to the home page, logging in, and then browsing to the Users Administrators page. To create the script, you simply followed the steps that an administrator would follow, but you did it using a browser window that is being spied on by your WAS session. The WAS tool watches what you do in the browser, and records each request and the server s responses into the test script. This cool feature saves you from needing to write the script by hand.

Figure 12-10. Adjusting WAS script settings You ve also specified a number of different settings that will affect the execution of the script when you use it in the performance test. In particular, there were three check box options at the beginning of the process (see Figure 12-7). In this case, we opted not to use any of them, but it s worth knowing their purposes: Record time delay between requests: Controls whether the script records the pauses you make while surfing the different pages of the application (this is known as think time, because it reflects the time that a user reads the content of a page and thinks about it before making the next request). Record browser cookies: Controls whether or not the cookies sent to the browser will be recorded into the script. Record the host header: Allows the recording of host header information. There s another think time control in the Settings dialog box (see Figure 12-10): the Use random delay check box adds further variety to the amount of time between requests, by introducing a random interval of time.
