❓ What is Performance Testing Tool?
Performance Testing checks the speed, response time, reliability, resource usage, scalability of a software program under their expected workload. The purpose of Performance Testing is not to find functional defects but to eliminate performance bottlenecks in the software or device
✅ Which are the Best Performance Testing Tools?
Here are some of the Best Performance Testing Tools:
❗ Why is performance testing important?
Performance testing provides stakeholders with information about their application regarding speed, stability, and scalability. More importantly, Performance Testing uncovers what needs to be improved before the product goes to market. Without Performance Testing, the software is likely to suffer from issues such as: running slow while several users use it simultaneously, inconsistencies across different operating systems, and poor usability. Therefore why, performance testing is a very important part of software testing.
✔️ What are different types of performance testing?
- Load testing
- Stress testing
- Endurance testing
- Spike testing
- Volume testing
- Scalability testing
⚡ Which factors should you consider while selecting a Performance Testing Tool?
You should consider the following factors before selecting a tool
- Desired Protocol Support: Web, Desktop, Citrix, SAP, etc
- License Cost if applicable
- In the case of an outsourcing project, you need to factor customer/Client preference of the automation tool
- The cost involved in training employees on the tool
- Hardware/Software requirements of the automation tool
