LOADRUNNER SCRIPTING TUTORIAL PDF

Record the Script: Usually, this is the first step of scripting where every user action is recorded into a script. Replay and Verify: Once the script is recorded, reply the script to ensure its working right. Verify any impact through application frontend or database. Enhance the Script: Once recording has been verified, enhance script by adding checkpoints, validating data, adding transactions and rendezvous points. Replay and Verify: As earlier, re-play your script and verify that everything is working as intended. Configure Runtime Settings: Configure and control pacing duration, think time variation, proxy settings and whether you wish to ignore any external resources.

Record the Script: Usually, this is the first step of scripting where every user action is recorded into a script. Replay and Verify: Once the script is recorded, reply the script to ensure its working right.

Verify any impact through application frontend or database. Enhance the Script: Once recording has been verified, enhance script by adding checkpoints, validating data, adding transactions and rendezvous points. Replay and Verify: As earlier, re-play your script and verify that everything is working as intended. Configure Runtime Settings: Configure and control pacing duration, think time variation, proxy settings and whether you wish to ignore any external resources.

Use for Load Scenarios: Formulate load scenarios based on test objectives. Use load distribution and geo-wide agents to make real like scenarios. This is why replaying LoadRunner scripts are always browser independent.

The console should look like snapshot below, look for your IP address in the shell: NOTE: if you close this window, the server will stop. The purpose of these controls are mentioned below: New Script and Solution: is used to start creating a new script. Alternatively, you can create a new script from the toolbar button. Remember, you need to keep the server running so do not close it. If the window bothers you, you can minimize it. You can also interact with HP Web Tours to ensure you can repeat the exact steps when recording.

Before one can start with scripting of any application SUL , one needs to get acquainted with the application flow. Step 2 A window to select the protocol is shown. The list looks slightly different from previous versions 1. Select Single Protocol 3. Enter Script Name 4. Click Create Note: You can use Protocol Advisor to determine right protocol your application uses for communication.

We will learn at a later stage how to determine the right protocol for your SUL. Tip: An application may require more than 1 Protocols sometimes to communicate with its server. For such a case, navigate to Multiple Protocols list on the left side of window. Tip: You cannot rename your scripts easily, so be creative when giving your scripts a name. Also, note that you cannot use spaces in a script name. You can notice the script files are blank, except basic signature of Function Action.

Below snapshot should help understand it more: Step 4 Click the Recording button which you can find in the toolbar.

Refer to the snapshot below: Step 5 a new window opens 1. If we study the above window, the name of the script is mentioned in the title bar of this popup.

This will help you make changes to the right script when you are dealing with multiple scripts opened at a time. If you do not see the rest of controls, click on the Fewer Options button to ensure you are not viewing fewer options.

Record into the action field determines where the code is generated after recording. VUGen facilitates switching to other actions or creates new actions during and after recording.

This option cannot be overridden once recording begins. Application: field tells VUGen, which browser to use for recording. Start Recording: Immediate vs. However, if you select Delayed recording mode, the VUGen will invoke the system SUL but will not commence capturing events unless you click on the Recording button from the floating bar.

A copy of your script will be available at this location as well, just in case if you lose your folder : 9. Start Recording: Will start recording. A floating recording bar will appear which will offer various controls over recording. This tells the time elapsed and a number of events automatically captured. In the snapshot shown above, the SUL has fired 56 events and a total of 0 minutes and 25 seconds of time duration has elapsed since recording began.

Ask yourself why. Can you answer? This is because no client to server communication takes place as you type. Hence, no events are fired and no script is generated regarding typing. The code will be generated only once you submit the form click Continue Recording can be pause using the pause button. Please note, as long as the recording remains paused, all events being fired by the application will be disregarded.

Switch to Action or create a new Action and continue recording. Refer to below snapshot to learn how to switch Action. The floating bar will look like this: Click OK to close the transaction label.

Click the Continue button of the application. End transaction by clicking button. Refer to below snapshot for illustration. From the floating bar, click on the button to insert a comment. A text box will appear adjacent to the floating bar where you can enter any text.

From the application, you can click continue. Close the application and click stop button from the floating bar. This includes generating code, transactions, and comments based on your recording. Refer to snapshot below. Once post generation operation is finished, you will see Design Studio window. You can safely click on the Close button, and VUGen will take you to the code that has been generated.

The window will look like this: As highlighted in the above figure, the editor contains easy to understand, readable code. You can have a look on the parameters used while recording. This encapsulates all the parameters associated with each request. Your script has been generated, click on the File menu and then click on Save Script As to browser the location where you wish to save your script.

The name suggested will be the name you mentioned when you started recording. All done. Now, congratulate yourself for having your first script successfully generated and saved. How did we decide which protocol should we use? The answer is not that simple. There is an architectural foundation set of skills you need to have in place as a prerequisite to answering this question.

If you are a beginner, you can pair up with someone who has solid client-side architectural and development skills for your SUL.

You can speak with the developers of your SUL and find out which interfaces your application leverages. This should lead you on a natural path to the interfaces that you will be using for your virtual user script development and protocol selection. To address the needs of beginners less knowledgeable in architectural skills, LoadRunner introduced a feature called Protocol Advisor in LoadRunner 9. While this has made life easier for many, one should rely more on the architectural and development skills instead of protocol advisor and receiving information from the development team about underlying development technologies.

Protocol may not suggest correct protocol in all cases. If you notice, this resembles a bit with the window appearing for recording. Specify the URL of the application that will subsequently be invoked.

Working directory can be left as such since this is merely a temporary directory for VUGen to use. Click the Start Analyzing button. A floating bar, somewhat similar to the record time floating bar will appear.

Have a look at the snapshot: The process will tell the time elapsed and a number of events fired. However, this information is not necessary. The only benefit of this events counter is, you know your client, SUL, is communicating with the server. It is a good practice to analyze only one business process at a time since the various business process in a large enterprise application may involve various protocols. For example, a dashboard in some application may have Ajax or Flex, etc.

The VUGen protocol advisor will come up with a summary report on the protocol suggestion. Have a look how it looks like: You can see the suggestions from Protocol Advisor. These may or may not be the best choices to pick. Hence this is discussed separately. A common myth is that the LoadRunner does not generate code in any other language. Another myth is that it requires a license to work in other languages.

Both are false. LoadRunner decides for itself which language to use when generating the script. For certain Java applications like Java applets the code being generated will be in JavaScript Language. This means, no matter how much a user wait, the think time generated the delay will be equal to value specified.

Rules 1 Manual Correlation: In manual correlation, we manually insert the correlation function in the script to capture the dynamic value. On a high-level, these are the steps to be followed for doing the manual correlation: a Identify the dynamic value s in the script: This can be done by recording the user actions on the application creating VuGen script twice with the same input data static values like user id, account number etc. Now compare the two scripts using text comparison tools like WDiff, BeyondCompare etc. We can use the in-build comparison option in VuGen which in turn will open the WDiff tool. As the value to be correlated is in the second request login request , and there is only one request above this, obviously, this value would have come in the response of the first request. So we will put the function just above the first request and replace the dynamic value in the second request with the parameter name note that parameters are always put in curly braces.
