Performance Testing Tools

The process of software testing plays a crucial role in Software Testing Life Cycle (STLC). It is one such procedure that ensures that the software functions and performs effectively in various conditions and under huge load. Performance testing is done to make sure an app runs fast enough to keep a user's attention and interest. To achieve this, one can find a vast variety of performance testing tools in the market that cater to all the performance testing needs of the client. Below is a comprehensive list of most popular performance testing tools used by software testers to test the performance as well as the quality of a software application.

    • It records user actions and replays them to emulate variable usage patterns.
    • Monitors load impact on application responsiveness and server infrastructure.
    • The result analyser can easily find hidden concurrency errors, which are left unexposed by functional testing.
    • Includes detailed application performance metrics.
  4. AppLoader:
    • A load testing solution designed for business applications.
    • Allows users to test any application by reproducing the same user experience from all access points: Thin, fat clients, and web portals.
    • One can test the entire business flow, including all third-party apps, without adding plugins or writing a single line of code.
    • It replicates the users’ interactions with the application and gives the testers valuable metrics about the end users’ experience, including screenshots of the failures.
  5. Apache JMeter:
    • An open source software with a 100%pure Java application designed to load test functional behaviour and measure performance.
    • Mainly considered a performance testing tool that is integrated with the test plan.
    • Used to test performance on both static and dynamic resources.
    • Can stimulate a heavy load on a server, group of servers, network or object, to test its strength or to monitor and analyse its performance under different load types.
    • It works under UNIX and Windows OS.
  6. LoadImpact:
    • A leader in load and performance testing, LoadImpact allows testing for website, web-app, mobile app or API over the internet.
    • This is an on-demand testing, which can be initiated instantly.
    • Mainly used cloud based testing.
    • It generates traffic to the website over a confined period of time by stimulating users to determine the maximum load and stress it can work on.
    • It works well on Windows OS and Linux.
    • Executes performance testing early in the development cycle, in each decided build cycle.
  7. Smartmeter.io:
    • A load and performance testing tool that provides advanced testing functions.
    • Get automatic in-depth reports for thorough performance testing.
    • Create test scenarios without any hassle in an embedded browser.
    • Provides continuous integration support and test acceptance.
    • It features automatically generated advanced test reports with all the necessary details about the test and its results.
    • One can see live results during the test run and get the features they always wanted.
  8. SOASTA’s Cloud Test:
    • End-to-end digital performance management tool.
    • Offers performance monitoring, measurement, testing, and analysis.
    • Directly load test databases by simply defining connection parameters & creating SQL statements.
