In this blog, we’ll see about performance testing and the tools required to do Performance Testing.
Before we move on, ask yourself this — What is performance testing?
We’ll have a quick overview of this.
What is Software Testing?
When a product is required and needs to be delivered within a certain time period, software testing is very important. We can find the bugs present in the software and check whether the built software matches the expected requirements and we can ensure that the software product is defect-free.
There are different types of software testing:
1)Unit Testing.
2) System testing.
3) Integration testing.
4) Regression testing.
5) Smoke testing.
6) Alpha testing.
7) Beta testing.
8) Performance testing.
9) Object-Oriented Testing.
Let’s see what is performance testing and why it is a necessary one to do in a software development lifecycle.
Performance testing:
Performance testing is a type of software testing that evaluates the speed, responsiveness and stability of a computer, network, software program or device under a particular workload.
Performance testing is also known as Perf Testing.
This type of testing needs to be performed so that we can understand how our software applications will respond with different load. When we perform performance testing we can determine speed, reliability and stability under the varying workload of our software.
What we can determine by performing performance testing?
There are different type of performance testing for different needs.
Load testing: It checks the application’s ability to perform under anticipated user loads.
Stress testing: This type of testing involves testing an application under extreme workloads to see how it handles the high load.
Endurance testing: It is done to make sure the software can handle the expected load over a long period of time.
Spike testing: It tests the software’s reaction to sudden large spikes in the load generated by users.
Volume testing: Under Volume Testing large no. of. Data is populated in a database and the overall software system’s behaviour is monitored.
Tools that are used to do performance testing:
- Jmeter
- load runner
- Open STA
- Load ninja
Now we’ll have a look into Jmeter,
Apache Jmeter:
The Apache JMeter is pure Java open source software used to perform load testing. It is Platform independent so no need to worry about the environment.
JMeter also supports visualization plugins that allow you to extend your testing. It can be integrated with Bean Shell & Selenium for automated testing.
No installation is required once we download the JMeter we can extract and run the batch file that’s it. The test result can be displayed in a different format such as chart, table, tree and log file.
There is a plugin called the WebDriver plugin, which we can download and we can use this to integrate with selenium and use this to do test automation.
