Performance testing is a non-functional sort of testing that entails evaluating software or an application to determine its current system performance. It evaluates how well your present system performs in terms of responsiveness and stability when subjected to various workload circumstances. Effectively, the system is tested under a variety of load and network circumstances, and the time it takes for the system to respond to these loads is meticulously monitored.
One of the most difficult aspects of web application testing is performance testing. Irrelevant web performance test data or incorrect metrics used during testing cost businesses a lot of money and time.
Fundamentals of Performance Testing for a web app:
These are the four fundamental elements or concepts that are included in all performance testing software. Choose any of them, and you’ll see the same set of features with added capabilities.
Capturing traffic at a network level
When I talk about traffic, I’m referring to HTTP traffic. This is the greatest level of abstraction that human eyes can easily see. It might be as easy as a GET or POST request to an HTTP site.
Wireshark is a network protocol analyzer that may be used on Windows, Linux, and Mac computers. It captures more data and is more insightful than Fiddler. A fiddler is a proxy tool for web debugging that can record HTTP(S) traffic. It is only compatible with Windows.
Analysis
Since we’ve now collected the traffic, carefully study it to determine the pattern or behaviour. Remove and filter any unsolicited calls and sounds.
WebLOAD is an enterprise-scale load testing tool with extensive scripting features that make it simple to test complicated scenarios. The tool gives a detailed study of your web application’s performance, identifying faults and bottlenecks that may be impeding you from meeting your load and response requirements.
Correlation
Although the recorded traffic is static, web performance is checking and testing with dynamic contents. The URL pattern is frequently dynamic, and the POST request may contain several inputs. Every dynamic characteristic must be correlated in order for our request to be unique and suit our objective. The Correlation data analysis tool is included in the Real Statistics Resource Pack. This tool computes Pearson’s, Spearman’s (rho), and Kendall’s (tau) correlation coefficients, as well as numerous one-sample correlation test variants.
What if you need to set up an account in a specific web application? The issue is that the account name or email address must be unique. As a result, if you submit the same request for account creation, it is possible that your request may not be granted.
Replay
This is the last step. You have all of the necessary associated data; simply run the scenario again. It’s as if you’re accessing the page with separate sets of input now. You may also wish to change the number of users, connections, and sessions based on the requirements of your test scenario. Web Replay is a tool for automated software testing of Web applications. It aids in the detection of defects and regressions in Web applications by recreating situations to test the programme. You can use WebReplay to automatically browse to a Web page, fill in form fields, click the submit (OK) button, and then move to another Web page.
Conclusion
Performance testing provides business managers with a pool of insights, data for effective decision-making, and reduces the number of risks the team may face when the product is out. Skipping critical processes or stages of the process, on the other hand, might mislead stakeholders and cause the product’s performance to be substantially overestimated. Hire a competent and experienced staff for a performance testing service.
