Every software application is different. As such, not all applications need to be performance tested. Additionally, the same application may not require repeated application performance testing for every release/cycle. This begs the question, ‘Under what conditions will an application need performance testing?’
Identifying risks to the performance of an application is a good way to start. You should look at risk factors that include the user population, application type, application technology and changes to the application features and function. Let’s look at each of these factors in detail.
Individuals who use your application are crucial to helping you decide on its risk potential. This becomes even more important if your customer base is continually growing. You should ask the following questions:
With the ability to expand different software applications available on the market, there is a corresponding increase in requirements to process large volumes of data in the background. This demand is in conjunction with the increase in expectation for improved or faster application performance. Therefore, it is important to understand the volume of data being processed for each job, whether it is hourly, daily or monthly.
Normally organisations do not make frequent technology platform changes from release to release. If your organisation is moving to new and future technologies such as mobile, cloud, IoT and big data, these application platforms must be performance tested.
If you are adding a new technology or replacing an existing one, it may pose a risk, which requires performance testing of the hardware change, alterations in the system architecture, network upgrade and/or application migration to a different data centre.
The amount of code change or new code deployment in an application can create new application performance risks. It is critical to understand the impact of code changes and their effect on functionality. You should ask questions such as:
If performance issues were discovered once an application went into production, it would require a detailed analysis of server resource utilisation patterns, usage trends and error logs for further risk mitigation.
Carrying an application performance testing risk assessment will help you answer the question, ‘Under what conditions will an application need performance testing?’ Performance testing cannot be simply ignored, because once you understand it, you can assess risks, make informed decisions and plan for the future.
