What is the importance of application performance for businesses?

performance testing need

With the rapidly changing customer expectations across the business landscape, the need for high-performing apps is growing in the market. Today, every business needs apps that perform seamlessly to attract new customers and retain existing users. Also, today’s customers expect companies to deliver apps that load fast and perform seamlessly even under peak loads to provide a great Customer Experience (CX).

Typically, businesses need apps that perform flawlessly under various conditions such as fluctuating networks, low bandwidths, high user loads, etc. For example, If a mobile application performance does not meet the user expectations, users are likely to abandon that app and switch to the nearest competitor. Invariably, the application or website or the web app performance plays a significant role. Therefore, to ensure that the apps perform seamlessly under all conditions, businesses must deliver a seamless user experience.

Performance Testing Overview

what is performance testing

Performance testing is a non-functional software testing method that validates the app’s speed, responsiveness, scalability, and reliability. This load testing method checks if the application performs seamlessly under varying networks, bandwidths, and under varying user loads. Some of the app issues identified with this type of testing are runtime error, optimization issues related to speed, latency, throughput, response times, load balancing, etc.

Why is Performance Testing Required?

Latest research analysts views on the need for high-performing apps

According to Statista, there are almost 3.5 million apps available on the Google Play Store and nearly 2.2 million apps available for iOS as of the second quarter of 2022. The report also states that only the best-performing apps stand out in the market and will attract customers.

Think with Google, a one-stop shop of Google for understanding industry trends, in one of its blogs on ‘Speed is key: Optimize your Mobile Experience,’ states that 29% of smartphone users will immediately switch to another site or app if the app is slow or doesn’t satisfy their needs.

According to a Pinterest Engineering Blog titled ‘Driving User Growth with Performance Improvements,’ it has been stated that Pinterest engineers ran an experiment in which they rebuilt web pages for performance. As a result, it led to a 40 percent decrease in Pinner wait time, a 15 per cent increase in SEO traffic, and a 15 per cent increase in conversion rate to new signups.

The above statistics showcase how critical the performance of mobile & web app or website is for businesses. Let us further understand the significance and the need of application performance across some major industries.

Benefits for Businesses Leveraging Performance Testing

performance testing benefits

1. Improves response time:

Response time is the total time taken by the software to generate an output against the input received. Typically, this testing method helps to improve the app’s response time by removing performance-related issues from the software.

2. Enhances the load time:

It is known that slow-loading websites annoy customers, and similar is the case with mobile apps having more load time, users either abandon the app or move to the nearest competitor. Typically, this testing method improves the loading time of applications by identifying and removing performance and load-related issues or bugs from the software.

3. Improves scalability:

The scalability of an app refers to its capacity to handle varying user loads seamlessly. This test helps in enhancing the load handling capacity of apps by testing the apps and websites under varying user loads.

4. Eliminates bottlenecks:

Bottlenecks are the barriers that decrease the responsiveness of the entire system. This performance testing method helps to find performance bottlenecks in the software by identifying the areas that cause the problems and helps to fix them by notifying the dev team promptly.

5. Helps in early identification and fixing of defects:

Performance testing allows testers to detect and fix performance-related issues faster and frequently. It enables testers to quickly identify issues and helps in faster resolution of bugs.

6. Speeds up the testing process:

In the earlier software development models like the waterfall model, the testers had to wait for the development process to get over to start the software testing. But in an agile environment, performance testing is integrated along with the development process, which speeds up the overall software testing process. Typically, a shift-left method of testing is followed in parallel to development which ensures faster results.

7. Enhances Customer Experience (CX):

Performance testing ensures delivery of high-quality products to customers in less time. Faster delivery of quality products enhances CX and makes the stakeholders and customers happy.
