Automation testing is one of the most important factors in the modern application development industry. This is because the dependency on the application development process has massively increased on automated testing practices. Since modern apps have become a one-stop solution, the application framework needs to have access to multiple elements of the application at the same time. For this process, the developers must ensure that the elements are not only functioning properly individually but also have a smooth performance when all of them are combined. It is almost impossible to execute these testing processes manually. So, the developers have to introduce automation testing practices with various automation frameworks like Playwright. Playwright is one of the most highly emerging names in the world of automation testing practices.
Since Playwright is comparatively new to the market compared to its competitors, there are various factors that app companies must consider before hiring developers and testers. Certain questions can help the app companies properly analyze the capabilities of the new Playwright-based testers. In this article, we will discuss some of the most important interview questions and answers that can help app companies during the hiring process. Let us begin our discussion with the basic knowledge of Playwright-based automation testing practices.

Creating a basic Idea of Automated Testing
To create the basic idea of automation testing, we need to understand the meaning of the name. This is because automation testing is the process of automatically starting and completing the test cases without any involvement of human developers and testers. For the execution of automated test cases, the system will use a text file that will contain all the necessary data and parameters. This data is important to help the system analyze the user interaction capabilities of the new web application. Moreover, the developers can change or add new parameters and datasets according to the requirements of the application development project. This process will help the developers to customize the test cases to improve the accuracy of the testing process.
Automation test cases are highly reusable. This means that the developers can reuse the testing code in future app development projects as well. While using test automation, the developers have the freedom of integrating third-party libraries, plugins, and other dependencies for improving the testing practices. However, while we’re on the topic of test automation, it is very important to mention one of the major drawbacks of this process. This is because while using automation testing, the developers had to spend quite a lot of money to get started with the process. This is because, with the initial practices of test automation, the companies have to install a lot of new softwares, plugins, and other platforms. So app development companies need to analyze their possible business perspectives before making the transition.
Benefits of Using Test Automation
Before we start discussing Playwright, it is very important to have a basic idea about the major advantages of introducing automation testing. Based on our analysis, the noteworthy benefits of test automation are as follows:
- Test automation helps developers to improve the efficiency of the testing process as it does not depend on the working capabilities of human developers. So the companies can run the test cases almost 24 hours the clock.
- Test automation helps application development companies to massively improve the test coverage This is because, with automation testing, the developers can verify the functioning of the new software or almost every device configuration.
- Automation testing helps developers to introduce new tools and platforms for further improving the efficiency of the testing process. We will discuss the role of tools and platforms in the later part of this article.
- Automation testing helps the developer to introduce parallel testing where they can execute multiple test configurations side-by-side.
Understanding the Core of Playwright
Playwright is one of the most efficient automation testing frameworks that help developers to initiate an end-to-end testing on their applications. End-to-end testing is one of the most important components of the modern application development process. This is because, with this testing process, the developers can ensure that any new addition to the application does not hamper the stable functioning of the previous elements. End-to-end testing is highly important for applications that undergo a frequent updating process. Another major advantage of Playwright is that with this framework, the developers can initiate end-to-end test cases on any platform or browser.
Top Playwright Interview Questions and Answers
Certain questions can help developers and app companies to analyze the capabilities of new Playwright testers. The answers to these questions will help analyze the understanding, experience, and vision of the new Playwright-based automation testers. According to our research, the most important Playwright interview questions and answers are as follows:
- What is Playwright?
This is the most basic question that helps to create a general idea about the knowledge of the developer. The answer is:
Playwright can be best described as one of the most modern cross-browser and even cross-language automation tools. This tool helps developers to execute end-to-end test cases on web applications. With Playwright, the developers can also execute the test cases on the mobile simulation of Google Chrome on Android and even safari on the iOS version. This makes Playwright an almost one-stop solution for all the end-to-end testing requirements on modern web applications.
- Is it possible to use Java or C++ with Playwright?
This is yet another basic question that almost every new Playwright developer or tester must be aware of. The most appropriate answer to this question is:
- How to Install Playwright Using NodeJS?
Questions like these are useful to verify the conceptual clarity of the new automation testers and developers. The most appropriate answer to this question is as follows:
- Which Browsers are Supported by Playwright?
These questions help the application development companies to understand the comprehensive knowledge of the developers about Playwright. It also helps to understand how the developers are keeping themselves updated with all the recent versions of Playwright. The answer to this question is:
At the time of download, Playwright comes with its bundle of browsers. As of now, Playwright provides native support for Google, Chrome, chromium, Microsoft Edge, Firefox, and WebKit. Playwright also gives the developers the freedom to either choose the bundled version or select any specific browser according to their requirements. All the relevant documentation regarding this process is available on the official website.
- Is there any WebDriver Dependency on Playwright?
This is a very important question regarding the dependencies of the Playwright. The most appropriate answer to this question is:
No, Playwright does not have any dependency on the WebDriver bindings. This is because Playwright can natively interact with all the elements of web applications. This is yet another feature of Playwright that gives it an edge over its competitors. The native engine Playwright is another unique factor that helps it to communicate with all the target elements of the web applications.
The Role of Tools and Platforms in Playwright Testing
Tools and platforms play a vital role in simplifying complex automation testing practices. Moreover, these tools can help reduce the learning curve when the developers are working with new automation testing frameworks like Playwright. Moreover, the developers can also access various new features using these tools. For example, cloud test platforms help developers eliminate a physical test bench which would cost a fortune to set up. This is because while using cloud testing platforms, the developers can initiate and execute the automation test cases over the web. We can gain more knowledge regarding the benefits of cloud-based testing by shifting our focus towards an excellent example LambdaTest.
To create a basic idea, we can define LambdaTest as a secure modern platform that helps developers easily execute cross-browser test cases on web apps. Considering the standards of the modern app development industry, we can safely conclude that automation test cases have become the new definition of ensuring the best performance to end users. This is because, with comprehensive automation testing practices, the developers can ensure a smooth end-user experience irrespective of multiple changes in browser version, operating system, or the entire device hardware. While using LambdaTest, the developers can import the automation test cases from multiple frameworks like Playwright, Cypress, and Selenium. It is worth mentioning that while using Playwright, the developers can run the test cases on more than 50 unique browser versions.
This Platform uses unique features like parallel test execution to improve the efficiency of Playwright test cases by almost 10 times. Moreover, the inclusion of real device testing along with existing emulators and simulators can massively improve the accuracy and dependability of the test cases. While using LambdaTest, developers can also ensure the stable performance of web apps that are meant for internal functioning and has a local host.
