Performance Testing: 6 Best Practices

by Asha Jane Brown | November 12, 2019 11:19 am

As far as modern mobile app users do not have time for stuck and slow applications that crash because of heavy workloads, an app should be checked for performance stability and speed before the market release. Performance testing helps to identify whether your application meets all the requirements for reliability and performance at an expected load.

We have gathered a bunch of useful advice on our blog and would like to share the best ones that will help you improve both app and site performance testing effectiveness.

Identify the Business Requirements

Identify the business requirements for application performance. You should not spend too much time on extreme tests for an application that is going to get relatively little traffic (for example, an internal application).

List the Relevant KPIs

Define the key performance indicators, e.g. average/peak response time, the peak number of simultaneous users. You can also combine these metrics. Remember to set realistic benchmarks based on practical and realistic scenarios.

Key Performance Indicators

Choose the Right Tool

There are many different performance testing tools available nowadays. Choose the right solution according to the needs of your company. For example, if you prefer the one with lots of code, then Gatling seems to be a better choice than JMeter for you.

Scale-Up the Load Gradually

As far as your goal is not to break the system, but to identify its bottlenecks, scale up the number of users gradually. This way you will find the point when the server does not handle the load properly. Understand the Risks Before the start of the testing project, identify the factors which can affect the performance of the application. Also, identify the conditions in which the app is supposed to be used most often. Use that data when creating test cases.

Include Performance Test into Unit Testing

Performance testing is mostly conducted at the late stages of the SDLC. Here changes are more expensive and hard to make. Think ahead and include performance tests into the Unit testing process. That will help you to quickly identify performance issues and eliminate them.

Moreover, this approach will make QA engineers and developers interact more closely, thus improving the quality of your product.

Look at the App from the Perspective of end-user

In most cases, the QA team[1] is focused on server responses. But actually, good server results do not necessarily guarantee a good user experience of your app. Make your tests cover the correlation of server testing results and user interface timings. Combining these two perspectives allows you to solve issues related to UX before app release.

QATestLab provides the services of software testing and quality assurance[2] to objectively assess the system operation speed, scalability, and stability. Using modern practices and approaches, we can help you to verify whether your app can withstand high loads as it was designed, thus providing the best user experience and high-level quality for your customers.
