* When in script development stage, you are checking whether the script is running without errors and are not concerned with response times. In this case, it is recommended to play back the script without any think time. When running the script for debugging you do not want to playback the script with think time – this will slow down the play back of your script and also at this stage of script building you are not concerned about response times from the servers. Main objective here is to build a script that works correctly. So set to ignore Think Time. * For the script to playback successfully make sure that you use the same settings that have used while recording the script. * The main purpose for running the script in VuGen is to be able to debug. Stop the script as soon as an error occurs and correct the problem. The main goal when running the script is to find problems if Continue on error option is checked the script will run despite error. This is not desired at this stage of script building. The script should be stopped as soon there is an error encountered in order to fix the error and rerun the script to establish that there are no other errors. * Emulate users using different connections modem, DSL, Cable are more relevant when load testing the application. When in debugging mode use default options. * Browser emulation is more relevant when running the load test and does not make much sense in script development stage. * For the script to playback successfully make sure that you use the same settings that have used while recording the script. * * * * * * Once you set the desired Run-time settings for running the script, run the script to ensure that it executes correctly by clicking the Playback button. When script execution is complete, communication between the Vuser and the server are listed in the Execution Log. The errors will be highlighted red. The above example shows Execution Log messages from a Web Vuser script. * * 脚本回放 第 2 章 设置合适的 Ru
