Website Performance Testing Tools and Services

Learn How to Perform Website Performance Testing with the Best Website Performance Tools and Service Providers:

Our previous tutorial briefed us on How to Perform Manual Performance Testing in simple terms.

Performance Testing is considered one of the most challenging tests. However, it is “the most important testing that is done for any website” as it directly impacts the revenue generated.

Website Performance testing isn’t as simple as functional or any other black box testing technique because of its complicated real-like setup required for testing.

It requires special attention and there are several factors to be kept in mind before performing this test.

Website Performance Testing

In this tutorial, I have covered details on what really is Website performance testing, what steps should we take to performance test a website, what tools can be used for testing, and some of its service providers in the current market.

What is Website Performance Testing?

A performance test is non-functional testing done to test the responsiveness, throughput, and scalability of a website under test. This mainly benefits in improving the user experience and increases revenue generation.

There are various types of performance tests that can be done like the ones given below:

  • Performance Test: This testing includes checking the responsiveness, speed, and scalability of the website.
  • Load Test: This is done to verify the website behavior under a certain workload.
  • Stress Test: This helps a tester find out how the system reacts under extreme load conditions. This helps in finding issues related to memory leaks, synchronization, etc.
  • Capacity Test: This test is done to ensure how many users/transactions can be supported at a time.
  • Endurance Test: This is done to ensure that the system will be able to handle the expected load for a long period of time.

How To Perform Web App Performance Testing?

Before you start performance testing a website, there are a few considerations that are to be kept in the mind.

They are:

  • Understand the purpose of the Website, try to find out if it involves payment gateways, web services, etc.
  • Understand the reason for performance testing and find out what actually needs to be measured like the number of users, volume, response time, etc.
  • Understand the customer’s expectations.
  • Understand the Project schedule and the QA window.
  • Understand the availability of resources and QA tools.

You can also create a checklist to note down the Performance Analysis/Acceptance criteria like:

  • What’s the acceptable time between transactions/user clicks?
  • What’s the expected average session duration of a user?
  • What’s the acceptable page load time?
  • Are there current baselines available to measure against?
  • What analytics tools are used to identify high volumes?
