Unlike Selenium WebDriver which allows you automated browser testing in a sequential manner, a Selenium Grid setup will allow you to run test cases in different browsers/ browser versions, simultaneously.
I believe that to work as a QA Manager is often considered underrated in terms of work pressure. To utilize numerous employees who have varied expertise from one subject to another, in an optimal way. It becomes a challenge to bring them all up to the pace with the Agile development model, along with a healthy, competitive environment, without affecting the project deadlines. Skills for QA manager is one umbrella which should have a mix of technical & non-technical traits. Finding a combination of both is difficult for organizations to find in one individual, and as an individual to accumulate the combination of both, technical + non-technical traits are a challenge in itself.

In the past few years, the usage of the web has experienced tremendous growth. The number of internet users increases every single day, and so does the number of websites. We are living in the age of browser wars. The widespread use of the internet has given rise to numerous browsers and each browser interprets a website in a unique manner due to their rendering engines. These rendering engines serves as pillars for cross browser compatibility.
Cross browser testing can turn out to be stressful and time consuming if performed manually. Imagine the amount of manual efforts required to test an application on multiple browsers and versions. Infact, you will be amused to believe a lot of test estimation efforts are accounted for while considering multiple browsers compatibility with the application under test.
TestNG is a Java-based open-source framework for test automation that includes various test types, such as unit testing, functional testing, E2E testing, etc. TestNG is in many ways similar to JUnit and NUnit. But in contrast to its competitors, its extensive features make it a lot more reliable framework. One of the major reasons for its popularity is its ability to structure tests and improve the scripts' readability and maintainability. Another reason can be the important characteristics like the convenience of using multiple annotations, reliance, and priority that make this framework popular among developers and testers for test design. You can refer to the TestNG tutorial to learn why you should choose the TestNG framework.
You can push your abilities to do automated testing using TestNG and advance your career by earning a TestNG certification. Check out our TestNG certification.
