What is Selenium?
Selenium is a powerful tool used for automating web applications for testing purposes. As an open-source software, it allows developers and testers to automate repetitive tasks, such as filling out forms, clicking buttons, or verifying elements on web pages, across different browsers. This flexibility makes Selenium one of the most popular choices in the field of automation testing. It supports multiple programming languages like Ruby, Java, Python, PHP, Perl, C#, and NodeJS, which makes it adaptable for different developer ecosystems.
One of the key features of Selenium is its ability to interact with web browsers in a way that simulates a user’s behavior, but without the need for manual intervention. The browser driver acts as a bridge between the test scripts and the web browser, ensuring that commands are executed correctly on the specific browser instance being tested.
Selenium’s architecture is divided into multiple components, each designed to handle specific tasks in the testing process. These components include Selenium WebDriver, Selenium IDE (Integrated Development Environment), and Selenium Grid. Furthermore, Selenium Grid allows parallel execution of tests across different machines and browsers, significantly reducing the time taken to run large test suites.
What is QTP/UFT?
A tool named QTP, now known as UFT, was created to carry out automatic functional testing without periodically checking the system.
Microfocus changed the name of QTP to UFT (Unified Functional Testing). Functional testing, regression testing, and service testing are the main uses of the program. UFT allows testers to automate user behaviours on a web or client-based computer program, test those actions, and find faults that may arise. This holds true for the identical activities performed by multiple users on various Windows operating systems and browsers using various data sets. If designed and carried out effectively, automation using QTP/UFT can save a significant amount of time and money.
- Several software programs and their environments can be tested using QTP/UFT.
- In addition to automating non-UI test cases like file operations, database testing, desktop apps, etc., it is used to conduct UI-based test cases.
- On the Windows operating system, QTP/UFT functions with numerous browsers, including Chrome, Firefox, and others.
- Additionally, it aids in doing QA checks on the software being tested.
- It provides simple navigation, validation of the results, and report creation.
