9. As part of our QA team, I am responsible for writing and maintaining manual as well as automated test cases. Many times when reviewing my test cases there are certain issues that occur only in certain browsers. I don’t always know which ones these are though so I end up having to manually check every single one just to make sure. Is there any way for me to find out if an issue occurs in only a few specific browsers without having to go through them all?

There is a tool called BrowserStack that can help with this. BrowserStack allows you to test your website or application in a wide variety of browsers, including many mobile browsers. You can also specify which versions of each browser you want to test against. This can help narrow down which browsers an issue is occurring in without having to manually test them all.

10. I’m looking for ways to reduce our current CI/CD pipeline times. One area where I think we could improve significantly is by making our UI tests run in parallel instead of serially. Are there any solutions you can recommend to help us achieve this goal?

There are a few different ways to run UI tests in parallel, but one solution that we recommend is using a tool like BrowserStack. BrowserStack allows you to run your UI tests across multiple browsers and devices simultaneously, which can help to significantly speed up your CI/CD pipeline.

11. I’ve been tasked with finding a way to increase the coverage of our current unit test suite. Currently most of our tests focus on back-end functionality but not much emphasis has been put into front-end testing. How do you think we could remedy this situation?”

One way to increase the coverage of your unit test suite is to focus on front-end testing. This can be done by using a tool like BrowserStack to test your front-end code. BrowserStack allows you to test your code in a variety of different browsers and devices, so you can be sure that your code is compatible with a wide range of platforms. This will help to ensure that your code is working as intended, and will help to catch any potential issues that could arise.

12. What is the difference between real device cloud testing and emulated mobile testing?

Real device cloud testing is testing on physical devices that are connected to a cloud-based platform. This allows for testing on a variety of devices from anywhere in the world. Emulated mobile testing is testing on a simulator or emulator that mimics the behavior of a mobile device. This can be done on a single device or on multiple devices.

13. What is meant by cross-browser compatibility?

Cross-browser compatibility is the ability of a website or web application to function correctly and consistently across different web browsers. Different browsers can interpret web standards differently, so it is important to test how a site or app will look and work on all major browsers before making it available to the public.

14. How will you monitor network traffic while testing?

There are a few ways to monitor network traffic while testing on BrowserStack. One is to use the BrowserStack Local Testing feature, which allows you to test localhost or internal servers. This feature will give you access to the BrowserStack Logs, which will show you all network traffic.

Another way to monitor network traffic is to use the BrowserStack Automate feature. With Automate, you can use the Selenium and Appium frameworks to write automated tests. These tests can include assertions that check for specific network traffic.
