16 Best Automation Testing Tools for Web Applications in 2021
Testing should always go hand in hand with website development It not only makes your code smooth and eliminates bugs but helps you achieve your business goals. In this article, we review the best website testing tools in 2021 that you can use to test your web software before and after the release
Types of web testing strategies
Your website consists of an architecture, a set of technologies, UI/UX design, and security practices. You need to check all these things to ensure your website or web app is working properly. There are lots of solutions for checking any given aspect of your website. Generally speaking, you can test these aspects:
- Functionality – check if all the website’s functions work properly and tests for correct responses from the backend. Functionality testing can be performed both manually and automatically.
- Usability – is usually checked manually. It helps to determine whether your web software is intuitive.
- Interface – check website’s layout: a QA specialist makes sure all the elements of the interface are in place and working correctly.
- Database – validate the data stored in a database and testing of database performance for actions like deleting, adding, and altering data.
- Compatibility – see whether a website works equally well on all popular web browsers.
- Performance – check the speed and load time on different browsers in different countries. It’s usually done automatically.
- Security – requires a complex set of strategies that include penetration, vulnerability, and risk assessment testing.
When it comes to the quality assurance process, there are three general approaches:
In this article, we’ll focus on automated best web application testing tools.
Functional and interface testing tools
Selenium is the most popular automated testing tool for websites and web applications. It’s one of the most flexible web test tools for regression and functional testing. Here’s the list of OSs, browsers, and languages it supports:
- Internet Explorer
- Headless browsers
Selenium isn’t just a single tool. Rather, it’s a set of components:
- Selenium IDE (Integrated Development Environment)
- Selenium RC (Remote Control)
- Selenium WebDriver
- Selenium Grid
These four components have their approaches to testing, so choose the one that best corresponds to your goals. With Selenium WebDriver, you can write more complex automation scripts. Note that in order to use Selenium, you need to be a skilled programmer who knows how to build automated scripts.
This is a disadvantage because not all quality assurance engineers and developers have the necessary knowledge.
Pricing: Free, open source
UFT is the second most popular commercial tool for functional testing. With UFT, you can test APIs, web services, and GUI test applications on all kinds of platforms, including mobile.

Security testing tools
Netsparker is a web app security tool that allows you to scan your web product for vulnerabilities and detect issues such as SQL injection and cross-site scripting (XXS) attacks.
Often, after scanning your software for vulnerabilities, you need to manually check if identified vulnerabilities are valid and indeed took place. That’s not the case with Netsparker, however, as it confirms all the issues it detects.
But if you still need to check, Netsparker supports manual testing and helps you with reporting, building HTTP requests and detecting 404 pages automatically. Netsparker also supports REST APIs.
Pricing: Free Trial. Standard version – $4,995/year
