    HtmlUnit

    HtmlUnit

    HtmlUnit

    HtmlUnit is a "GUI-Less browser for Java programs" that models HTML documents and provides an API to interact with web pages, such as invoking pages, filling out forms, and clicking links, similar to a standard web browser. It offers fairly good JavaScript support, which is constantly improving and is capable of handling complex AJAX libraries, simulating browsers like Chrome, Firefox, or Edge depending on the configuration used. Typically used for testing purposes or retrieving information from websites, HtmlUnit is not a generic unit testing framework but is intended to simulate a browser within another testing framework such as JUnit or TestNG. It is utilized as the underlying "browser" by various open source tools like WebDriver, Arquillian Drone, and Serenity BDD, and is employed by many projects for automated web testing, including Apache Shiro, Apache Struts, and Quarkus.

    SlimerJS

    SlimerJS

    SlimerJS

    SlimerJS is a free, open source scriptable browser for web developers, allowing interaction with web pages through external JavaScript scripts. It enables tasks such as opening web pages, clicking links, and modifying content, making it useful for functional tests, page automation, network monitoring, screen capture, and web scraping. Unlike PhantomJS, SlimerJS runs on top of Gecko, the browser engine of Mozilla Firefox, instead of WebKit, and can operate in both headless and non-headless modes. APIs of SlimerJS are similar to the APIs of PhantomJS but there are a few differences in their behavior. However, most of the scripts for PhantomJS run perfectly well with SlimerJS right now.

    IBM MQ
    Massive amounts of data move as messages between applications, systems and services at any given time. If an application isn’t ready or if there’s a service interruption, messages and transactions can be lost or duplicated, costing businesses time and money to make things right. IBM has expertly refined IBM MQ over 25 years on the market. With MQ, if a message can’t be delivered immediately, it’s secured in a queue, where it waits until delivery is assured. Where competitors may deliver messages twice or not at all, MQ moves data, including file data, once — and once only. Never lose a message with MQ. IBM MQ is available as software to run in public or private clouds, in containers or on your mainframe. IBM also offers an IBM-managed cloud service (IBM MQ on Cloud) hosted on IBM Cloud or Amazon, and even as a purpose-built Appliance (IBM MQ Appliance) to simplify deployment and maintenance.
