Automation testing interview questions and Answers 1

Automation testing interview questions and Answers 1 In today’s software sector, automation testing is a full-fledged career. Automation testing professionals collaborate with the development team to meet project deadlines, which has resulted in a number of benefits and a lucrative career for modern-day professionals. Here are the 51+ Automation Testing Interview Questions you should know before your next interview. Automation Testing Interview Questions: The following are some of the most often asked questions in interviews for both freshers and QA professionals. 1) What is Automation? Automation is a word for applications where reduce human efforts. There are include business process automation (BPA), IT automation, personal applications, business- related applications, E-commerce applications such as home automation, and more. 2) What is Automation Testing? Automation testing is a process of using automation software tools to write a script to perform test cases such as entering data and comparing the results, etc. is known as Automation testing. The goal of Automation Testing is to reduce the number of test cases to be run manually so we can reduce human efforts 3) How do you identify the test cases which are suitable for test automation? Identifying the particular test cases for automation is the most important part of automation. If the test case is stable then it is beat for automation. 4) What are the types of automation testing? There are different types of automation testing. Like exploratory testing and some other that you can automate Unit tests: The unit test is written by developers and test small units of code in isolation. Integration tests: After performed Unit testing, all module is merged and then we are performing integration testing to verify how all component work combine together. Regression tests: In regression testing, we are testing like updated code didn’t break any existing working functionality. Performance tests: Here verify that the application won’t crash under heavy load and stress. UI tests: Test there is all text and images are displayed properly, and there are no broken graphical elements on the page. 5) What is the difference between automation testing and manual testing? Manual Testing Automation Testing A human executes the test cases one by one his/her self, without any software help it is called manual testing Test cases are executed by any automation testing tool, without human efforts It is automated testing. Useful for non-repeatable tests that involve human skills, involvement, and domain experience. Useful for repeatable test cases where the application feature under test doesn’t change frequently. Good for accessibility and usability testing, as the tester can test the software as end- user point of view. Good for regression testing to make sure that the software didn’t break after updating code changes. Can be slow and more time-consuming, and sometimes getting errors because of human misjudgment. It’s run by a computer, so there are no chances for error, and test case execution is fast. Humans can test the software in a randomized manner, and it is also known as exploratory testing. This type of testing is not possible in automation testing. UI issues and some variances are easily found by a human tester. In automation testing, we cannot cover UI issues. performance Testing is impossible to test with extreme load by a human tester Performance testing can be easily done by automation testing. The tester doesn’t need knowledge of programming. To write automation test cases, the tester needs to have programming knowledge. 6) When is a good time to automate a test? Under the following condition, it is a good time to automate a test • The test cases are repeatable. • The test cases under the automation testing don’t change their functionality again and again. • Some test cases are more time-consuming for a human tester. • Some test cases are connected with complicated calculations. • The test ensures the existing functionality didn’t break after an update of the code change. 7) When will you avoid automated testing? In the following situation, we will avoid automation testing • When the Application Under Test and changes come regularly • One time test cases • Adhoc testing • Automation testing is not useful for exploratory testing because a human tester can more explore the application with much better scenarios than a computer. • Automation testing is also not used in UI testing 8) How do you choose a tool/framework for automated testing? To perform any automation testing, we need to choose software tools or frameworks. There are many options to choose from many alternatives. Here some are criteria based on that we can evaluate the tools. • Programmable (code-based) or code-less tools. Some tools require knowledge of programming, while some tools don’t require, without any skill of programming allow to create test cases with visual assistance. so, in that situation, you can choose your tool based on your team’s experience and skill-set. • Commercial vs. Open Source. There is a more difference in the price of the tools it is based on the feature which they are provided. Most commercial tools are more expensive, but they get tech support if you are facing any issue. Open-Source software is free, but you have to search if you are in trouble. • Ease of use. Some Automation testing tools are difficult to using and required training before using this tool. Some are easy to understand we can use without any training. Some of the most famous automation tools like Katalon Studio, Selenium, UFT, TestComplete, Testim, etc., and many more. You can choose anyone based on the requirement of your project, assess the team’s skills, the experience of all team members, and comfort with the tool. 9) What are the different parts of a test automation framework? Below is the different part of automation framework Test Data Management Generating test data is the main problem of automation testing. A good test case automation framework is making it easy to build test data for the application at the testing time Testing Libraries A Good automation framework provides libraries so test management make easy and also support different types of testing like integration testing, unit testing, and end to end testing Testing Tools 1. Includes any GUI or command-line tools that make it useful for testers to run the set of tests again and again. 2. Testing tools are also useful for a tester to perform load and stress testing 10) Should you automate all testing? We can not automate all types of testing. Some types of testing are only done by human testers like interface testing, usability testing, and accessibility testing. Exploratory testing is another type of testing where a human tester can test better than automation testing. A human can provide more scenarios and tester more explore the software randomly and tried to find UI bugs easily as compare to automation testing. Automation testing is useful for large projects where complex calculations and repeated test cases are available. 11) What is a test environment? A test environment is a computer or a server on which a tester can test the software or applications. After the developer team builds the software, the tester installs it on this computer or on a server with all its required dependencies, like the production environment. This allows the tester to test the software or application with the real- world scenario. Actually, the test environment is a copy of the production or live environment. These allow the tester can make a duplicate copy to reproduce the same bug for reporting and the test can provide the exact steps to a developer to fix them. Below are the some of prerequisites for a good test environment: • A test server has a similar configuration, including software and hardware to match with the production environment • Sample test data for testing with software. • Test database with real data, it can be a copy of the production database. 12) What is browser automation? Browser automation is one of the techniques for launching a web application in a browser programmatically and executing different actions by automation, just like a regular user would. Browser testing gives you the speed and efficiency that human testers cannot provide. There is a different popular tool for browser testing like Protractor, Cypress, and Selenium. 13) What is automated regression testing? Software is never completed. The developers are continuedly updating features, functions and fixing bugs So because of that chance to break existing working functionality. And because of that tester need to perform regression testing. Regression testing is a testing technique where makes sure that updated code is not affected by the existing working functionality and didn’t break any working functionality. The main foal of regression testing is to make sure that previously tested and working functionality still works fine after adding new changes in code.
