Watir is made to automate web application testing and this is done using Ruby libraries. Watir is also called as water by the people and is an open source testing tool.  This tool can be used to tests any language-based web application. Watir works well with RSpec, Cucumber, and Test/Unit and is a business-driven development tool. It basically tests web page’s buttons, forms, links, and their responses. It can be used on a number of browsers as it is compatible with them.

Designed for developers, Cypress is an end-to-end solution “for anything that runs inside the browser.” By running inside of the browser itself, Cypress can provide for more consistent results when compared to other products such as Selenium. As Cypress runs, it can alert developers of the actions that are being taken within the browser, giving them more information regarding the behaviors of their applications.
The Automation test suite should be indicated if any of the integration pieces are broken. This suite need not cover each and every small feature/functionality of the solution but it should cover the working of the product as a whole. Whenever we have an alpha or a beta or any other intermediate releases, then such scripts come in handy and give some level of confidence to the customer.

He prefers to use the term “automated test execution” when discussing test automation because the majority of people are referring to automating that activity in the testing process. Non-technical testers should have access to the automation tools. Today’s modern automation technology makes it possible for teams to collaborate and benefit from automated testing.  
TestComplete allows you to build and run functional UI tests. This is an automation testing tool that is well suited to test desktop, mobile, and web applications. The tool allows you to write test in most popular languages such as Python, JavaScript, and VBScript, etc.  It allows you to record and replay tests.  It offers GUI UI object recognition capabilities that detect and update UI objects automatically. It helps in reducing the efforts required to maintain test scripts. With TestComplete it is rather easy to scale tests across 1500+ real test environments to provide complete test coverage.

“There are millions of regression tests for a Windows 10 release. For example, if you plan 10 new features, five [of those 10] are critical and a priority. These test cases will be the criteria used to release the software. You build from that progress. So on the next release, you have new features, 10 are determined critical for testing. So it keeps adding, now you have 15 regression tests being automated to keep up with the release schedules.”

Robust GUI test automation begins with the reliable object identification provided by Ranorex Spy. This tool can be used alone or from within the Ranorex Studio environment to deliver industry-leading recognition of GUI objects and controls, and ensure that each user interface element is uniquely identified using the powerful RanoreXPath syntax. Information on identified objects can be shared with team members through snapshot files, or stored in the Ranorex object repository for use in automated tests. The object repository in Ranorex Studio manages identified UI objects, so that they are editable and re-usable across testing projects. Features of the repository include the ability to assign meaningful names to repository objects to make them more maintainable, set default values, or link objects to parameter values. Ranorex Studio tools support best practices in automated test case design, including separation of test data from procedures, use of local and global parameters to pass values, and easily reusable code modules that can be shared by the entire team.
