It is crucial for today’s businesses to visualize that Performance testing forms an integral part of quality assurance. Application Performance Testing is the solution to determine high-performing mobile apps, E-commerce applications, and other customer-facing apps. Performance-tested applications assure that released software satisfies the agreed Service Level Agreements (SLA’s) and essentially gives higher user satisfaction levels. Such well-tested systems perform seamlessly even below diverging load conditions with concurrent users.
Statistically, only applications that function well even when the concurrent users access it without any glitches manage to attract and retain the customer base. Such apps help to accelerate their respective brands. Hence, it is important for companies to take up effective performance testing procedures to maintain and protect their brands.
There are several performance testing tools that can be used to achieve effective performance on mobile apps, e-commerce, and other systems. Some of these tools are available as open-source and paid tools, which are used to implement different types of performance testing such as Load, Stress, Spike, Volume, Capacity, and Soak testing.
7 Performance Testing Tools
The top 7 performance testing tools which are employed widely by performance testing services in 2021 and their functionality are as follows:
Tool Overview: It is the most broadly used tool to test applications, test system behavior, and their performance below varying loads. The tool is used to simulate thousands of concurrent users and record the changes in system performance. Afterward, leveraging those outcomes, the performance of key components of the application can be examined. This tool supports all advanced technologies like HTML5.0, Ajax, Flex, Java, SOAP, Citrix along with all other legacy technologies
Tool Functionality: It supports testing of a broad range of applications along with continuous testing. The tool efficiently recognizes performance bottlenecks and displays the root cause analytics.
2. Apache JMeter:
Tool Overview: It is an essential open-source tool used to test the performance of both static and dynamic applications. It is a Java-based application employed for load and performance testing, which is done to test Web applications, SOAP & REST web services, FTP, databases, and more. Interestingly, JMeter is also a broadly used performance testing tool, which is efficiently used to load test web and mobile applications and test their performance.
Tool Functionality: Originally it was intended for testing web applications, but later on it has been extended to test other test functions. It is also used for simulating a heavy load on a server or a group of servers and essentially monitors application performance below varied load conditions.
Tool Overview: This is a broadly used tool by companies for testing web and mobile applications. It is an efficient tool as it combines performance, scalability, and integrity as a single method for testing applications. It is a replacement for LoadRunner.
Tool Functionality: This tool is utilized to create mobile load tests either by recording native mobile apps or browser-based apps, straight from the mobile handset. The ease of the tool is; the user can update any scripts, add parameters, and conduct validation checks. After creating mobile scripts, it performs the mobile load tests and this tool integrates with a real mobile device.

Tool Overview: It is used for cloud-based load testing and enables DevOps teams to efficiently test web apps, websites, and application programming interfaces (APIs) with thousands of concurrent users. The agile and DevOps teams can examine their website’s UX under load, test performance, and recognize various bottlenecks within applications. This tool simulates API calls, confirms API responses, and checks the most important SLA requirements.
Tool Functionality: LoadView utilizes the Google Cloud Platform (GCP) and Amazon Web Services (AWS) to create concurrent user load over the cloud during the load tests. The agile teams can examine the most complex applications by designing multiple test situations to test for. This tool tests and decides if the website (under testing) can handle spikes in traffic by creating a load with a set number of concurrent users. Also, it tests the limits of infrastructure, every time by altering the load in real-time. The test results can be observed in LoadView’s web interface and reports can be achieved either in CSV or PDF formats.
5. LoadUI Pro:
Tool Overview: This tool is utilized for load testing REST, SOAP APIs, databases, and microservices. The simplicity of this tool is, it does not need a specific skill set in load testing and any user can design and execute tests. It is used to guide in creating realistic performance test scenarios.
Tool Functionality: With LoadUI PRO, there is a flexibility to reuse all functional API tests developed on the industry’s best open source tools. It helps to decrease the time taken to deploy REST and SOAP web services. It gives key insights that help to repair any performance bottlenecks. Its powerful and natural capabilities help to deliver scalable APIs. This tool is used to examine the speed and scalability of new modifications to the APIs in a short span of time. Users can get insights from real-time API load tests and assure that the API will handle any demand effectively.
Tool Overview: VSTS stands for Visual Studio Team Services; is a continuation of Microsoft Visual Studio. It is an integrated development environment (IDE) and is normally operated in the cloud (Azure). The tool is utilized to load test mobile applications or website’s performance before their launch to verify any performance bottlenecks even before it reaches the consumers.
Tool Functionality: This tool is used to manage URL-based load tests with Azure DevOps and sets all the necessary parameters to run the test. When the test is finished, the results illustrate the overall application performance on a separate summary page. This page displays critical metrics such as user load, average response time, requests per second, failed requests, other intervening failures along test usage. Response time pinpoints the time an application has exercised to respond to requests which are the important metrics for measuring any app’s performance.
Tool Overview: This tool helps to stress test environment to assure the website or an application is stable even below the spikes or in heavy traffic. It creates actionable insights that help dive into the live data and efficiently know any performance issues while load testing is in progress. It allows continuous testing process in the cloud (anytime without worrying about any hardware), eliminates traditional costs, and provides more value to it.
Tool Functionality: This tool is a valuable global load testing platform that is scalable and used to run tests to get actionable insights from the results.
However, before picking any performance testing tool, it is essential to consider certain factors such as – verify whether the tool is capable to satisfy the user’s expectations, ability to meet the business goals, etc. This will support building a good testing solution for the requirement.
These performance testing tools play an essential role in allowing businesses to avail top-rated applications without any performance glitches. Businesses require to essentially get their applications tested for performance to assure that they satisfy the agreed SLA’s. Performance is the solution to the livelihood of mobile apps and mobile-optimized e-commerce sites to operate seamlessly.
Specific performance testing tools can be utilized to efficiently test applications and businesses can leverage independent testing service providers to have their applications tested.
