Software testing comprises different methodologies and requires one to consider many different aspects to deliver a high-quality solution to the client or customers. However, the success or failure of your testing efforts entirely depends on the selection of the right kind of testing methodology. One such method is performance testing. Performance testing plays a vital role in the testing process.
Today, you can find many enterprises or organizations suffering from a wide range of performance related issues. The main reason behind this is because they never spare time to test their applications under real world scenarios.
What is performance testing?
It is nothing but a means of quality assurance (QA) that involves testing software or applications to make sure they perform well under critical conditions. It is a non-functional type of software testing. It helps you determine how fast a few specific aspects of a system or application respond in the worst conditions. The goal of performance testing is not to find bugs but to eliminate performance bottlenecks.
The prime focus of this kind of testing is to scrutinize a software application’s speed to help you determine if the application responds immediately or not. It also determines how much user load the application can tackle and if the application is stable under different loads.
A number of other benefits include:
- Helps enhance user experience.
- Boosts online revenue.
- Conducts metrics important to tune-up the system.
- Determines bottlenecks like database configuration.
- Helps you determine if a new version is prepared for production.
- Lets the stakeholders know if the performance met their expectations
However, to understand the significance of performance testing, it is important to first understand the different types of testing included in it. There are seven types of performance testing.
Performance test: Verifies stability, performance, scalability and/or throughput of your website.
Capacity test: It helps you determine the number of users your website or application can tackle before performance or stability become unacceptable.
Load test: Imposes load to an application and measures the outcome.
Stress test: As its name suggests, this kind of testing will push your application to perform beyond its normal conditions. It will let you know which components fail under pressure.
Soak test: It is one of the long running tests, which is used to evaluate application performance and/or stability over time. It is useful when you wish to track down memory leaks.
Component test: Whenever you wish to test any discrete component of your application — file upload, a chat feature etc. — you may require a component test.
Smoke test: This kind of test is conducted under very low load, which highlights if the application works as expected. If smoke is generated, it means the test was failed and no more testing is required.
Performance testing offers many benefits, but still many organizations fail to take advantage of it due to some silly mistakes. If you wish to get maximum benefit from this kind of testing, avoid making the mistakes discussed below:
Many organizations overlook performance during the design phase, which leads to many kinds of problems later on. To avoid such issues, it is better to incorporate performance measures at the very beginning.
Delaying testing until the completion of the software application increases the chances of missing out on some of the major performance affecting issues.
Testing an application against a single use case scenario limits your understanding of how your application will perform in different scenarios. Therefore, rather than testing for a single use case scenario, try to use various testing tools and test your app under different scenarios.
Some teams perform their tests within a firewall due either to low budget or security issues. However, it won’t help you know how your application will perform in the real world.
Performance testing will not only boost customer satisfaction with your apps, it will protect your investment. What’s your take on this? Share it in the comments.
