26. Apache JMeter HTTP(S) Test Script Recorder
> This tutorial attempts to explain the exact steps for recording HTTP/HTTPS. For those new to JMeter, one easy way to create a test plan is to use the Recorder.
> 26.1 JMeter configuration
> Since JMeter 2.10, recording has been improved to better handle embedded resources and creation of certificates on the fly. To enable these features, JMeter uses `keytool` utility (available in JRE/JDK) so you need to ensure your configuration is correct, read this wiki page before starting.
> 26.2 Basic Instructions
> > Go to `JMETER_HOME/bin` and start JMeter with `jmeterw.bat` on Windows and `jmeter.sh` on Linux/Unix Select `Templates…` on the menu bar
> > Select `Recording template` on the list
> > A complete `Test Plan` is generated
> > 5. In the `HTTP Request Defaults` element: `Server name or IP` enter `example.com` `Path` leave blank
> > Return to `HTTP(S) Test Script Recorder`, and click the `Start` button at the top.
> This will start the JMeter proxy server which is used to intercept the browser requests. A file called `ApacheJMeterTemporaryRootCA.crt` will be generated in `JMETER_HOME/bin` folder. Install this certificate in your browser, if you don't know how to do it, read Installing the JMeter CA certificate for HTTPS recording
> 26.3 Configure your browser to use the JMeter Proxy
> > 2. At this point, JMeter's proxy is running. For this exercise, we will use Iceweasel/Firefox to view some pages on the JMeter website. Start Iceweasel/Firefox, but do not close JMeter. From the tool bar, click Edit → Preferences (or Tools → Preferences or type `about:preferences#advanced` as URL). This should bring up the options.
> > 5. Select the `Advanced` tab, and `Network` tab Click `Settings` button near the top. On the new pop-up, check `Manual proxy configuration`. The address and port fields should be enabled now. `Address` enter `localhost` or the IP address of your system `Port` enter `8888`.
> Check `Use this proxy server for all protocols` Click `OK` button. This should return you to the browser
> 26.4 Record your navigation
> > With your browser, in the `Address` bar at the top, enter `http://example.com/index.html` (replace `example.com` with your websites address). and hit the `enter` key. Click on a few links on your sites pages. Close your browser and bring up the JMeter window. Expand the `Thread Group` and there should be several samplers. At this point, the test plan can be saved as is.
> > If you forget to add default HTTP Request settings, you will have to manually delete the server name, and port.
> > 1. In this sample, there aren't any default request parameters. If a particular request parameter is required by all pages, the request defaults is where one would add the entries. Select `Thread Group` and change a few defaults: `Number of Threads (users)` enter `5` `Ramp-Up Period (in seconds)` do not change `Loop Count` enter `100`
> 26.5 Validate the script
> > Now we need to validate the script before to run our test plan. Save the test plan. Right click on the `Thread Group` Validate
> Check with `View Results Tree` element if all is ok.
> 26.6 Variabilize and Correlate the script
> > In some scripts, we will need to: Variabilize some input (login, password, search words, …) Correlate some data (session variable, …) between two requests To variabilize, we can use: `CSV Data Set Config` to get input data from csv file JMeter functions like `__counter`, `__time`, … etc. To correlate, we can get data from a request with `Post Processors` like `JSON Extractor`, `Regular Expression Extractor`, … and inject it in another request. To find data to correlate, the easiest way to do it is to use the Search function in `View Results Tree`.
> 26.7 Start the test
> > At this point, we are ready to run our test plan and see what happens. When you're ready to run the test, there are two ways: With the gui, but it's not recommended to big load test. With the command line. Solution 1, with the gui, but just during debug phase, use Non GUI for your load test. Run → Start or use the keyboard and press Ctrl + R Before you start the test, add a `Summary Report` element and select it. As the test runs, the statistics will change until the test is done. At the end of the test, the summary report should look like this.
> > While the test is running, in the upper right-hand corner, there should be a green circle. When the test is done, the circle should be grey.
> Solution 2, in command line, use `jmeter -n -t [jmx file] -l [results file] -e -o [Path to output folder]` At the end of the test, an HTML report will be generated and available in [Path to output folder] used in command line.
