Do you have your business running on online platforms?

Or

Do you have a freshly started website that’s all set to support your digital presence in the market?

If yes, then possibly your biggest goal is to get as much footfall on your website as possible in the shortest time given. That’s how all your efforts to go digital will finally give you fruits. Right?

And what if that actually happens?

Imagine your perfectly functioning ecommerce website one fine day gets a thousand more new users and BOOM… it crashes.

Don't be surprised because this is not a usual hypothetical story. It’s a real life scenario that happens quite often with companies who do not follow a testing drill before launching their applications online. What follows is poor performance and bad user experience. It has been noted that 42% of the users who come across a poorly performing website leave the page and hop on to other similar services providing websites immediately. That increases your website bounce rate and tells a lot about how your website has been performing all this while.

To avoid this scenario, developers often include a step in their software development process called software performance testing.

Read along to know more about performance testing what are the most popular tools that can be used for testing your website.

What is performance testing?

Performance testing is a non-functional testing technique used to determine the speed, responsiveness and stability of a system or device under various workloads. It measures how the quality of the system is i.e. the scalability, reliability and resource usage.

There are six basic techniques commonly used for performance testing:

· Load testing — The simplest form of testing, load testing is conducted to analyze the behaviour of a system under a specific load. It helps in measuring the essential business-critical transactions and monitors the potential load on the database, application server, etc.

· Stress testing — It helps identify the upper limit of load endurance for a system and anticipate the behaviour of the load exceeds way above its expected limits.

· Soak testing — Soak Testing also referred to as endurance testing, is performed under the continuous expected load. Parameters such as memory utilization are tested to determine if there exists any memory leaks or other performance issues.

· Spike testing — used to determine if the system will be able to handle any additional workload, spike testing is done by suddenly increasing the number of users of an application to a very large amount.

· Volume testing — Very large amount of data is inserted in a database and then the software system’s behaviour is monitored in volume testing to check the software application’s performance under different levels of data inserted.

· Scalability testing — used to determine the effectiveness of an application while scaling up the load. It can help you plan your scalability needs is to ensure your application doesn’t break.

Why is performance testing important?

Some of the reasons why performance testing is important are:

1. Mobile app errors

It has been noted that a lot of mobile applications today report errors post their launch in the market. While working on unreliable network errors, applications face network issues, that lead to issues in downloading images, broken images, frequent timeouts, stalling and freezing etc.

2. Frustrated customers and loss of revenue

Poor application experience leads to an increased bounce rate on your web app or other pages. This means that your user would leave as soon as they land on your website because of a poor engagement or increased loading time.

3. Geographical barriers

Different regions have different connections i.e. 2G, 3G, 4G, etc. that have varying speed requirements in their networks. It is important to test your application on various region’s servers to ensure that all your user sitting in different parts of the world can access your application with ease.

4. Performance under High Demand

It is easy to rate an application good during its development stage. But the moment the number of users increases the chances of your application breaking down increases. Optimum levels of testing can ensure your application is ready for added scalability, speed and stability requirements when the demand increases in future.

What are the best performance testing tools?

1. Apache Jmeter Tool

LoadRunner is used to test applications measure system behaviour and performance under load. A software testing tool from Micro Focus, LoadRunner helps simulate 1000s of users currently using applications software by generating messages between application components or by simulating interactions with the user interface such as keypresses or mouse movements.

Core Features and components:

Virtual User Generator (Vugen): Mainly used for recording an application business flow and generating scripts.

Controller: The component where you upload Vugen scripts is a controller. It helps simulate hundreds of users, and monitor different web servers, application servers and database servers.

Analysis: Analysis provides you with different graphs that help identity bottlenecks quickly. It can be used after the testing has been completed.

Load Generator: A tool used to generate load from different machines. You can easily install different load generators in machines and connect them all to a controller that can act as a master and will help gather data from other generators.

Load Generator Calculator: This will help you calculate how many load generators will be required for simulating the load in your system.

4. BlazeMeter Tool
