Introduction to Web Application

Web application testing is a critical process that every business needs to perform to ensure that their application meets the user’s expectations. In today’s world, where the internet is a crucial part of our lives, web application testing has become more important than ever. In this blog, we will discuss web application testing, including JMeter and Selenium testing, which are two of the most popular tools used in web application testing.

What is Web Application Testing?

Web application testing is a process of verifying and validating the functionality, performance, and security of a web application. The objective of web application testing is to ensure that the application meets the user’s requirements and is error-free. Web application testing involves various testing methodologies such as functional testing, performance testing, security testing, and usability testing.

Exploring JMeter Test:

JMeter is an open source software tool that is used for analyzing and measuring the performance testing of web applications. It was developed by Apache Software Foundation and is widely used by software developers and testers around the world. JMeter can be used to test the performance of a wide variety of web applications, including static and dynamic resources such as HTML, CSS, JavaScript, AJAX, JSP, Servlets etc.,. It is a Java-based application and is available for download on Apache website.
It can be run on any operating system that supports Java, including Windows, Linux, and MacOS. The tool is designed to simulate a large number of users accessing a web application simultaneously, and it measures the performance of the application under various conditions.
JMeter also supports a wide range of testing scenarios, including load testing, stress testing and functional testing. Load testing involves simulating a large number of users accessing the application to its limits to see how it performs under extreme conditions. JMeter script should be prepared in a realistic way i.e. by adding delay between each user action which we call it as Think Time. This will allow the virtual user to pause between the business flows, while moving from one to another transaction.

Boost your Application’s confidence with Frugal Test - Scale Up under various Conditions

Start your first free load test, that is, by entering the URLs/APIs endpoint of your web apps or mobile apps or uploading your scripts (JMeter) without any charges taken for your test. This test is nothing but a FRUGAL TEST. Frugal testing involves identifying the most crucial areas of the software and focusing testing efforts on those areas. It also involves prioritizing test cases based on their potential impact on their system. The best tools for JMeter Testers are Fiddler, Postman, Badboy, Developer Tool.
What happens when too many unexpected users hit your application and your servers are not ready for that huge load. This results in downtime of your application, downtime which undoubtedly means huge loss to your business. Then Frugal Test comes into picture, this will help in scaling up your application under various load conditions. This will boost your confidence that the application is capable of handling the load conditions before going LIVE.

Exploring Selenium Test:

Selenium is also a popular open-source automation testing tool used to test web applications. It can be used with several programming languages such as Java, Python, C#, and Ruby, making it a versatile tool that can be easily integrated into any project. It supports a range of web browsers, including Google, Firefox, Internet Explorer, and Safari making it possible to test web applications across different platforms and browsers.
Selenium IDE script for performance testing in JMeter:
Selenium IDE (Integrated Development Environment) is a browser plugin used for record, edit and playback of tests for web applications. It supports multiple browsers, including Chrome, Firefox, and Microsoft Edge. It can save time and effort in the testing process. However, it may not be suitable for complex testing scenarios that require advanced programming knowledge and customizations.
Selenium IDE scripts in JMeter can help automate performance testing web applications, which can save time and effort compared to manual testing. The Selenium WebDriver sampler in JMeter allows users to run Selenium scripts as part of a load test, which can help identify performance issues in the application. The sampler executes the Selenium script in a headless browser, which simulates user interactions with the application. The number of threads in the  Thread Group Specifies the number of users, and the iterations specify the number of times the test scenarios will be executed.

Conclusion:

By using JMeter and Selenium together, software testers can ensure that web applications are performing well under heavy loads, and the application’s functionality is working as expected. This can help identify performance bottlenecks and other issues that can affect the user experience and ensure that the application is working as intended. With the comprehensive web application testing practices outlined in this article, software teams can deliver high-quality products that meet user needs and are delivered on time.
