What is Performance Testing Tools

Performance testing is a non-functional type of testing that is conducted to determine how an application will perform under load. The tests are conducted on metrics including speed, stability, and scalability. The right performance testing services can conduct a wide range of tests. Find out what the different types of performance tests are and the best 9 performance testing tools that are currently trending in 2021.

Types of Performance Tests

The different types of performance tests conducted by performance testing services include:

  • Load Testing: This tests the workload that is produced in normal conditions and measures the application’s response time. It also helps in identifying any bottlenecks.
  • Stress Testing: Extreme workload is applied to find out the load point at which the app will crash.
  • Spike Testing: This involves changing the workload rapidly and monitoring the application’s response.
  • Endurance Testing: This involves exposing the application to the expected workload for a prolonged period of time to check how well it can handle it.
  • Scalability Testing: This test involves a gradual increase in workload to find out how efficiently the software can scale up.
  • Volume Testing: Volume testing involves the performance testing services feeding the software’s database with large volumes of data to check its data processing capabilities and efficiency.
