QA Testing

    Selenium is among the most well-liked open source Web UI (User Interface) automation testing technologies. It was initially developed by Jason Huggins in 2004 as a tool for internal usage at Thought Works. Selenium provides automation for a variety of operating systems, coding languages, and web browsers.
     Selenium is simple to install on operating systems like Windows, Linux, Solaris, and Macintosh. Additionally, it supports Android, iOS, and Windows Mobile OS (Operating Systems) for mobile apps.
    Selenium supports a broad variety of programming languages by using drivers created especially for each language. C#, Java, Perl, PHP, Python, Ruby, and Selenium are a few of the languages it supports. The Selenium Web driver's two main supporters right now are Java and C#. The majority of modern web browsers come with built-in functionality that allows Selenium test scripts, which may be created in any of the supported programming languages, to be executed. Selenium supports the browsers Internet Explorer, Mozilla Firefox, Google Chrome, and Safari.

    Cypress is a JavaScript-based, open-source automation tool that is covered by the MIT license. It has over 19.3K stars on GitHub as of the time of this writing and is used by companies like NASA and DHL. Cypress End to End test makes it easy to create and troubleshoot unit and integration tests.
     Cypress provides a visual interface that displays which tests and tasks are presently running, succeeding, or failing in addition to the test script runner. It enables us to test highly interactive apps and perform a variety of tests, including modifying the DOM, asserting that if a specific element is available or present on the screen, reading or writing data into/from fields, submitting forms, and even forwarding to another website.
    Cypress has been developed as a tool for regional development. You might even be persuaded to do all of your programming there after using Cypress for a while because it provides a platform for quick code debugging and straightforward code maintenance.

    An open source framework for automated testing called Robot Framework is utilized in test-driven development and acceptability testing. Numerous test cases, such as keyword-driven, behavior-driven, and data-driven, are followed while writing them. This feature makes it really easy to understand. Test cases are written in a tabular format using a keyword approach. High-quality external libraries, open-source software, and automation tools are supported by Robot Framework. The most popular library used with Robot Framework is the Selenium Library, which is used for web development and user interface testing.

    Postman is a tool used to test APIs. By serving as an interface between different programmers, an API establishes a connection between them.
    An API is a collection of terms, provisions, and resources that a software programmer may make available to its users in order to enable successful communication with other software applications. We require an API each time we use a program, such as Facebook or the phone to check the news.
    In order to make the development and testing of APIs simpler, software engineer and entrepreneur Abhinav Asthana founded Postman in 2012. It is a software evaluation tool for APIs. It can be applied to the creation, modification, and planning of APIs.
    One of Postman's features is the capability to send and track HTTP (Hypertext Transfer Protocol) requests and responses. It has a graphical user interface and works with Linux, Windows, and Mac operating systems (GUI). Numerous HTTP requests, including POST, PUT, GET, and PATCH, can be built and converted to code.
