Performance Testing Tools Load Test

Load testing is an important part in performance testing of any application. It is a must before making your application live. Actually it is always recommended to do load testing as we can never predict how customers will use the product at later stage. Therefore only by testing you can know how many concurrent users your system supports.

Performance testing is crucial to ensuring the high-quality and high-availability of any application. Performance testing ensures that your application performs as expected under load.

In fact, load testing one of the most misunderstood parts of performance testing, and there are many load testing best practices you should be aware of before even using one of the tools listed below.

Here are is our comprehensive list of the top open-source and FREE performance load testing tools you can use for your load and stress testing performance engineering efforts.

Below are some options that include a tool comparison to help you make your decision on what tool to use for your application performance efforts in 2021.

What is Performance Testing?

Performance Testing is a type of software testing which ensures that the application is performing well under the workload. The goal of performance testing is not to find bugs but to eliminate performance bottlenecks. It measures the quality attributes of the system.

The attributes of Performance Testing include:

attributes- performance testing tools - edureka
  • Speed – It determines whether the application responds quickly.
  • Scalability – It determines maximum user load the software application can handle.
  • Stability – It determines if the application is stable under varying loads.

Now let’s move ahead with our “Performance Testing Tools” article and have a look at why do we need performance testing.

Top 10 Performance Testing Tools | Edureka

This edureka video on “Performance Testing tools” will help you know about Performance Testing and the different tools available for testing. It will provide the features and protocols for the best performance testing tools.

Why do we need Performance Testing?

  • Performance testing informs the stakeholders about the speed, scalability, and stability of their application.
  • It reveals the necessary improvements needed before the product is released in the market.
  • Performance Testing also ensures that the software is not running slow while several users are using it simultaneously.
  • It also checks the inconsistency across different operating systems.

These were just a few out of the many reasons why we need performance testing. Now let’s move ahead with our “Performance Testing Tools” article and have a look at the different advantages of it.

Advantages of Performance Testing

validate features - performance testing tools - edureka

Validate Features – Performance testing validates the fundamental features of the software. A solid software foundation is a key principle of generating software success. Measuring the performance of basic software functions allows business leaders to make key decisions about the setup of the software.

measure - performance testing tools - edureka

Measure the speed, accuracy, and stability – Measuring performance speed, accuracy and stability is a vital aspect of software performance testing. It helps you in monitoring the crucial components of your software under duress. This can give you vital information on how the software will be able to handle scalability.

users - performance testing tools - edureka

Keep your users happy – Measuring application performance allows you to observe how your customers respond to your software. The advantage is that you can pinpoint critical issues before your customers.

  • Real-life Case Studies
  • Assessments
  • Lifetime Access

Identify discrepancies – Measuring performance provides a buffer for developers before release. Any issues are likely to be magnified once they are released. Performance testing allows any issues to be ironed out.

optimization - performance testing tools - edureka

Improve optimization and load capability – Another benefit of performance testing is the ability to improve optimization and load capacity. Measuring performance can help your organization deal with volume so your software can cope when you hit high levels of users.

Types of Performance Testing

The different types of performance testing are:

  • Load testing – It checks the application’s ability to perform under anticipated user loads. The objective is to identify performance bottlenecks before the software application goes live.
  • Stress testing – This involves testing an application under extreme workloads to see how it handles high traffic or data processing. The objective is to identify the breaking point of an application.
  • Endurance testing – It is done to make sure the software can handle the expected load over a long period of time.
  • Spike testing – This tests the software’s reaction to sudden large spikes in the load generated by users.
  • Volume testing – Under Volume Testing large no. of. Data is populated in a database and the overall software system’s behavior is monitored. The objective is to check the software application’s performance under varying database volumes.
  • Scalability testing – The objective of scalability testing is to determine the software application’s effectiveness in scaling up to support an increase in user load. It helps plan capacity addition to your software system.
