Selenium
Software Freedom Conservancy
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well. If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point. -

Selenide
Selenide
You don't need to think how to shut down browser, handle timeouts and StaleElement Exceptions or search for relevant log lines, debugging your tests. We are proud to claim that Selenide is so simple that you don't need to read tons of documentation. Selenium WebDriver is a great tool, but it’s not a tool for testing. It’s a tool for browser manipulation. There are several testing libraries around Selenium WebDriver. But it seems that they do not resolve the main problems of UI tests. Namely, instability of tests caused by dynamic content, JavaScript, Ajax, timeouts etc. Selenide was created to resolve these problems. First of all, Selenide makes your tests stable by resolving (almost) all Ajax/timing issues. We are proud to claim that Selenide is so simple that you don't need to read tons of documentation. The whole work with Selenide consists of three simple things!Starting Price: Free -

Apache AntUnit
Apache Software Foundation
Initially all tests for Apache Ant tasks were written as individual JUnit test cases. Pretty soon it was clear that most tests needed to perform common tasks like reading a build file, initializing a project instance with it and executing a target. At this point BuildFileTest was invented, a base class for almost all task test cases. BuildFileTest works fine and in fact has been picked up by the Ant-Contrib Project and others as well. This approach has a couple of advantages, one of them is that it is very easy to translate an example build file from a bug report into a test case. If you ask a user for a testcase for a given bug in Ant, he now doesn't need to understand JUnit or how to fit a test into Ant's existing tests any more. AntUnit takes this approach to testing even further, it removes JUnit completely and it comes with a set of predefined <assert> tasks in order to reuse common kind of checks. -

Inspectle
Inspectle
Inspect Element is a built-in tool in most web browsers that allows users to view and edit a website's HTML, CSS, and JavaScript code in real time. This feature is particularly useful for web developers, designers, and digital marketers to debug elements, test layout changes, and perform live CSS editing. The tool displays the HTML structure of the webpage, allowing users to select and inspect specific elements. The associated CSS styles are shown in a separate panel, where users can make temporary modifications to see how changes would affect the page's appearance. These adjustments are local and do not alter the actual website; refreshing the page will revert to the original content. This functionality is invaluable for testing design changes, troubleshooting issues, and learning how different web elements are constructed. Our platform is designed around flexibility. Each production site in the world is unique and so is the solution.Starting Price: €24 per month -
