After recording and debugging, script enhancement step gives a beauty to the LoadRunner script. Script enhancement has some important steps like parametrization, script factorization, etc. Some of the steps are optional which you can skip:
1. Parameterization:
Parameter helps to replace hard-coded values from the script with the test data. In VuGen, you just need to select the value, right-click on it (the value you want to replace with parameter) and select option ‘Replace with a Parameter’ or ‘Use Existing Parameter’ option. For more detail, you can refer to the Link.
2. Add / Edit Transactions (If not given at the time of recording):
Transactions are the user steps. They help to capture the response time and error for a particular request or user step. You can provide the name of the transaction either during recording or post-recording. Also, if a transaction name does not match with the business flow or want to change then you can easily modify it.
3. Rendezvous Points:
Rendezvous Point helps to achieve the user concurrency at any step in the script. A rendezvous point creates intense user load on the server and enables LoadRunner to measure server performance under load for that particular functionality. Refer to the link to get more details on Rendezvous point and policy.
4. Add / Edit Think Time:
Think time is a pause time which a real user takes to read the content of the page. It makes a scenario more realistic. It is a good practice to insert think time (lr_think_time(n) where n is a delay in seconds) between two transactions. You can also find recorded think time function in the script whose value can be edited. Refer to the link to get more details on think time.
5. Update Runtime Setting:
Run time settings provides overall control on the Vuser script. You can update it as per the requirement. It generally covers run-logic, think time, pacing, enable/disable logs etc. Refer to link for detailed information on Runtime Settings.
Note: Performance Center/Controller can override the run time settings of VuGen.
6. Insert Comment:
Add the comment in the script wherever required. Read More >>
These are some basic steps of LoadRunner script enhancement which help to create a perfect and comprehensive test script.
