In automated testing the test engineer or software quality assurance person must have software coding ability, since the test cases are written in the form of source code which, when run, produce output according to the assertions that are a part of it. Some test automation tools allow for test authoring to be done by keywords instead of coding, which do not require programming.

Selenium is perhaps the most popular automation framework that consists of many tools and plugins for Web application testing. Selenium is known for its powerful capability to support performance testing of Web applications. Selenium is a popular choice in the open-source test automation space, partly due to its large and active development and user community.
As a business management software, is an appropriate choice for mid-sized companies as it offers expense tracking, invoice reports, CRM support along with an easy integration of project details. It is extensively used in consulting, marketing, management, and other technical industries. It is like your entire business within your palm of hands.
Manual software testing is performed by a human sitting in front of a computer carefully going through application screens, trying various usage and input combinations, comparing the results to the expected behavior and recording their observations. Manual tests are repeated often during development cycles for source code changes and other situations like multiple operating environments and hardware configurations. An automated testing tool is able to playback pre-recorded and predefined actions, compare the results to the expected behavior and report the success or failure of these manual tests to a test engineer. Once automated tests are created they can easily be repeated and they can be extended to perform tasks impossible with manual testing. Because of this, savvy managers have found that automated software testing is an essential component of successful development projects.

I think we can all agree that automation is a critical part of any organization's software delivery pipeline, especially if you call yourself "agile." It's pretty intuitive that if you automate testing, your release cycles are going to get shorter. "So, if that's the case," you might say, "why don't we just automate everything?" There's a good reason: automation comes with a price.
