7 most Common Performance Testing Mistakes

Whether you are making a mobile app or a web app, the performance of your app will determine if it will be successful or get lost in the crowd of thousands of other apps. Thus, performance testing is a mandatory part of any app development. Whether you call it load testing, stress testing, soak testing or reliability testing, you have to do it properly to get the right results.

It is not a checklist that should be done in a hurry to complete your app deployment. If done well, it can give you great insight into the performance bottlenecks and into the areas where you need to work on to make your app better. So, take a look at these common mistakes which you should avoid in your performance testing to ensure your app is top notch.

1. Not Planning

The biggest mistake many developers may commit is to not do any performance testing at all. Then they realize that it is needed and quickly put together some tools and conduct some half-baked testing that is not going to be of any use.

Do not be one of those developers and you should thus:

  • – Plan for performance testing from the pre-production stage.
  • – Be able to define the level of quality assurance and performance criteria during the design stage itself.
  • – Design your service level agreements before the production, which means that planning for performance testing has to start early.
  • – Fix the methodology for testing and schedule all the activities related to performance testing beforehand.
  • – Establish the key performance indicators (KPI).
  • – Make sure your testing process is well planned and on schedule.

 2. Not Using the Right Tools

There are many paid and free versions of performance testing tools available. If you fail to choose the right one during the planning stage, you can be faced with the problems later.

Know what you want to achieve and choose your tools accordingly.

For instance, if your application is a web app, you may need an automation testing tool that can create the necessary load parameters. If it is a mobile application, you should choose a testing tool that can simulate real-time conditions specific to mobile devices.

3. Not Using the Right Data

You will not be able to measure the true performance of your app if you fail to use the right data.

Testing has to be done exhaustively and you thus need real-time data and not a small amount of static data.

So, make use of data generation tools and include production data to give more realistic input to the tests.

4. Not Testing at the Right Time

If you think testing is an end of the day activity, then you are mistaken. This is a common mistake that many developers and organizations make.

Putting off testing until the last phase of app development will be an expensive and difficult task.

To avoid this, do the following:

  • – Try to run performance tests regularly throughout the development process and make sure you are going in the right direction.
  • – Test every single unit, your infrastructure, and the database regularly.
  • – Don’t wait for the entire app to be completed before starting your performance testing.

5. Not Using Real-Time or Distributed Testing

Many organizations choose to run their performance testing within their own LAN networks, which gives a little insight as to how the real environment would be like.

Though this type of testing saves money, it does not give a true measure of the app’s performance.

To avoid this, do the following:

  • – Use the technologies that will allow you to distribute your testing into the cloud and give it a more real-world experience.
  • – Avoid testing from a single location within closed firewalls.
  • – You can also use network emulation tools and create virtual user groups for more efficient performance testing.

6. Not Analyzing Each Test

When you run long tests that are time-consuming, there is a greater chance that some of the short tests will go unnoticed.

You need to avoid this mistake, as these short tests can give you significant information on the environment and the efficiency of the scripts used in testing.

Pay attention to each test and analyze them for anomalies and errors. You should also use monitoring tools to report on anomalies and correlate the statistics in various formats.

As soon as you find a problem, immediately fix it. Use accurate tests to get accurate results.

7. Not Focusing on the Longevity and Correctness

Testing for server crashes is not the sole aim of performance testing and focusing on a single use case is not the right way to get the best results from testing.

You need to pay attention to other performance scenarios as well and use various statistical approaches to determine the performance. Consider factors like user experience, functional correctness, and longevity.
