Testing is actually defined to identify and improve the coding to improve its efficiency and make it bug-free.
Before we pen down all the details on web testing, let's quickly define what is web testing? In simple words checking your web application for possible bugs before it's made live or you can say that checking web application before the code is moved into the production department is called web testing.

Most Frequently Asked Testing Interview Questions

Here in this article, we will be listing frequently asked Testing Interview Questions and Answers with the belief that they will be helpful for you to gain higher marks. Also, to let you know that this article has been written under the guidance of industry professionals and covered all the current competencies.

Q1. What are the Advantages of Manual Testing and Automated Testing?
S.no Manual Testing Automated Testing
1. It is easy for the beginners who have just entered into the quality assurance industry to kick start career. It can be used in different versions of the software, so it in the end reduces the cost to test different types of similar softwares.
2. WordPress websites, their inner links and all the plugins of the system are defined and it’s easy to verify the plugins and links in the system. It’s in the hand of testers to define the test suites and write the suitable test scripts for the program to check, so they can easily build the test suites that can check all the features of the system easily.
3. As different features are there, and also it is developed by different teams. So, parallel development is possible. It can be used in different versions of the software, so it in the end reduces the cost to test different types of similar softwares.
4. Plugins mostly have only one type of functionality to perform, so the developer’s mind is also focused on a single thing and can dedicate time towards one thing Testers have the added advantage to program very hard tasks which can easily unveil any hidden information in the software that is being developed.

Q24. Give some examples of priority – severity defect levels.

Usually priority – severity defects are divided into four categories, Low priority-Low severity, Low priority-High severity, High priority-Low severity, and High priority-High severity.

To example, these defect level: a spelling mistake in a page non-frequently navigated page will be categorized as Low priority-Low severity, whereas application crash in some very corner case will be defined as Low priority-High severity. For High priority-Low severity case example, brand name spelling mistake and logo colour change can be mentioned. And, login functionality issue can be categorized as High priority-High severity defect.

Q30. Is UI level testing possible?

Yes, UI level testing is possible. But, we can do far from that. As early feedback is crucial for every testing project, we don’t need to wait until the UI layer gets developed. We can test the APIs directly, so that we can share crucial feedback early in the project development, giving developers more time to fix the bugs more proficiently.

  • Security Testing
  • Crowd Testing

To know more about testing interview questions, we are defining some of the Manual Testing Interview Questions and Automation Interview Questions.

During testing, we dig all the possible issues like the functioning of the site, ability to handle traffic, web application security, its access to regular users or handicapped, and much more.

When we talk about Software testing, it is a process of evaluating the functionality of a software application with one aim to find whether the software met that particular requirement or not and to spot the defects to ensure that the software is defect-free in order to make the quality product.

There are two types of software testing one is manual testing and another one is automation testing. You can do testing in a static way or dynamic way. Even there are different levels of testing like unit testing, integration testing, system testing, and the last one is acceptance testing.
