Bean Test: Part 1: HOW TO RUN PERFORMANCE TESTS USING JMETER ON MOBILE APPS

Introduction:

In this tutorial, we will look like overview of how to install and start Jmeter 3.2 and we will also learn about the basic Jmeter and how to run performance tests on mobile apps.

What is Jmeter?

JMeter is a 100% Java application, open source software, designed to load test for analyzing and measuring the performance of variety of applications , with a focus on web applications.

Why Jmeter?

Open source testing tool and the most popular performance tool.
Easy to download and install.
Have huge community support.
Can test for web app or mobile app
Can view result by table, graph

Prequities:

JMeter now requires Java 8.
JMeter logging has been migrated to SLF4J and Log4j 2.

Downloading and Installing Jmeter

Step 1: Download file and Install the latest JRE or JDK. This is needed as JMeter is a pure Java application.

Link : http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.htm

Step 2: Download file and Install the latest Jmeter (version 3.2)

Download the latest version of Apache JMeter binaries (tgz or zip) form: http://jmeter.apache.org/download_jmeter.cgi

Unzip the file on your desired path.

Steps to Launch JMeter : Go to your JMeter bin folder to launch JMeter, then run jmeter.bat (in windows ) file or jmeter.sh (in linux, MacOS) in here.

Launch of Jmeter

Example : How to run performance an App in Mobile with Jmeter
Step 1: Create a Thread Group and Add Recording Controller.
- First, add a Thread Group to Test Plan: Right-click on Test Plan > Mouseover Add > Mouseover Threads (Users) > Click on Thread Group
- Add User Defined Variables : - Click on Thread Group > Mouse over Add > Mouseover Config Element> Click on User Defined Variables

Then, add a Recording Controller: Right-click on Thread Group > Mouse over Add > Mouseover Logic Controller > Click on Recording Controller

Step 2: Create a test script. First, add a HTTP(s) Test Script Recorder to Test script: Right-click on WorkBench > Mouseover Add > Non-Test Elements > Click on HTTP(s) Test Script Recorder
- Add ‘8080’ as Port value and click the Start button. This will start the JMeter proxy on localhost
Step 3: On Android phone, get CRT file from apache-jmeter-3.2\bin and install on mobile. Then configure proxy of mobile

Android proxy configuration:

Go to Settings>Wi-Fi option > connected network and click the “Modify Network” option > Check the “Advanced options” check box > Set ‘Proxy’ option to “Manual” > Set “Proxy hostname” as your computer’s IP address and ‘Proxy port’ to 8080 as we have set up in JMeter configuration > Click “Save” option.

Step 4: Add Listener and Run the Test Plan. Right-click the Thread Group (Users) > Choose Add > Listener > View Results Tree / Summary Report

Then click Start button

The way to create scenario and activities

* Input data to test by CSV file.

First, create CSV file. In This example, I saved the file as “xxx.csv” (telephone and code country)

Then go into JMeter and find the HTTP request step that you want to modify to use the values in this CSV file. Right click on it and go to Add > Config Element > CSV Data Set Config.

Next click on the CSV Data Set Config step to modify it

You’ll need to fill in at least 3 values on this screen:

+ Filename: if your file is in the /bin directory, this can be just the filename.
If it’s somewhere else, use the full path to the file.

+ Variable names: this is the equivalent to a “column name” in a spreadsheet.

+ Delimiter: comma is the default delimiter.

After the CSV step is filled out correctly, go back to your HTTP request and change the value of the “phone” and “zone” fields to variables.

*The number users to test. Right-Click the Thread Group and add User Defined Variables Config Element in your JMeter test

Create a new variable: protocol with value https

Go to the HTTP Request and add the variable name where you want to be replaced with its value, use ${protocol}

Result -> CSV file -> report. Right click Thread Group and Add -> Listeners -> Aggregate Report
- Configure the filename in the Filename field of the Aggregate Report.
Ex: [FULLPATH]/results.csv
- Run the test script and file with the results.csv name should now be created at the path specified
