Interview Questions
The following are the most important questions to prepare for an Automation Testing Interview so that you can ace it the first time around.
Q. Describe a test environment.
Ans. A test environment is a computer or server that is used to test software. To replicate the production environment, the tester installs the team’s recently developed software on this workstation, together with all of its dependencies. Thus, a real-world scenario can be used to test the application.
Q. Should every test be automated?
Ans. While test automation has advantages, it is not practicable to automate every type of testing. Testing that can only be completed by a human tester includes accessibility, usability, and user interface testing.
Manual Testing ensures a high-end User Experience to the software’s end user, as it requires human observation and cognitive abilities. This helps them find errors that automated tests might miss. That is also the main reason why you will always need a human to review the tests made by automated testing tools.
Using automated tests to emulate every single scenario related to a feature can be time-consuming. Manual testing allows testers to spend less time concentrating on emulating each unique user path possible and more time thinking about edge cases for complex features and functions.
Q. When will automated testing be eliminated?
Ans. Here are a few scenarios where software testing can be performed more effectively by a human tester than by an automated test suite.
Regular updates are made to the software or functionality being tested. It means that in order to maintain your automated tests up to date, you will need to update them often. Because of this, testing may quickly become dated and useless.
Additionally, automated testing is not suitable for exploratory testing. Software may be investigated far more thoroughly by a human tester than by a computer. The automated tests won’t detect any UI bugs unless they are configured or programmed to do so.
Q. Describe the various components of a framework for test automation.
Ans. It is necessary to employ various software tools or frameworks for automation testing. There are many options from which to select. These are some qualities to take into account when assessing these instruments.
Programmable (code-based) or code-free tools: Certain tools require programming experience, while others don’t, so a tester who isn’t a programmer can create test cases using visual assistance.
Commercial vs. Open Source: The tools’ prices differ significantly based on the functionality they offer. Commercial products are more expensive, but you receive technical support when needed. Even though open-source software is free, troubleshooting requires research.
Easy to use: Before offering any benefit, certain automated testing methods are known to be highly complex to operate and require extensive training. Some are immediately usable and easy to use.
Q. When is a test appropriate to be automated?
Ans. A test is appropriate to be automated if it meets the following criteria –
- Tests that need to be performed repeatedly, like as regression tests
- If the behavior of the tested feature is not being consistently changed
- The test requires intricate calculations that cover critical functionalities or high-risk scenarios where human error is more likely to occur
- The test verifies that the new modification did not cause any issues with the previously functioning features.
Q. How does browser automation work?
Ans. “Browser automation” is the technique of automatically running a web application in a browser and performing additional tasks. Popular tools like Selenium enable the automation of tasks such as opening specific URLs, interacting with web elements like buttons and forms, and validating results.
Automation scripts simulate user actions, allowing for the testing of web applications or the execution of repetitive tasks. This process enhances efficiency by reducing manual efforts and ensures consistent interactions with web pages. Despite its advantages, browser automation is not a one-size-fits-all solution and is often used in conjunction with manual testing for comprehensive web application testing.
Q. What is cross-browser testing?
Ans. Here, the tester assesses whether the online application functions correctly across various browsers like Internet Explorer, Safari, Chrome, Firefox, and others. The aim is to ensure seamless performance across this array of browsers.
Q. Why is cross-browser testing necessary?
Ans. When engaging with web applications, you lack influence over the myriad devices, platforms, or browsers individuals might employ to access your program. Conversely, cross-browser testing serves as the assurance that your online application seamlessly functions across various platforms and devices, accommodating diverse versions of widely utilized web browsers.
Q. Describe Automated regression testing.
Ans. A tester using the regression testing approach verifies that none of the previous features’ functionality is broken. Its distinct goal is to verify that functionality that has been tested and produced still works when new code is added.
Q. What is the pyramid of test automation?
Ans. Martin Fowler created the test automation pyramid initially, and it was made public in 2012. It is a technique for determining the most efficient way to use the many kinds of testing automation. The core principle of the test pyramid is to have a large number of user interface (UI) unit tests and a relatively small number of thorough UI tests.
Q. What does automation testing mean, in your opinion?
Ans. Automation is generally used to describe any procedure that requires less human labor. Automation testing is the practice of carrying out repetitive activities with software, bots, or any other tool to get rid of flaws, faults, or vulnerabilities in the script.
When multiple changes are needed on a frequent basis, automation testing is extremely important to the software development process of continuous testing and continuous delivery. Testing, however, is a different process within the software development life cycle that calls for skilled personnel and the use of testing instruments.
Q. Which automation tests are commonly employed in the industry?
Ans. Many different kinds of automation testing exist, depending on the requirements: Unit testing is done during the development phase to identify and fix process issues.Testing the application’s front end or user interface is done through graphical user testing, or GUI testing.
To evaluate the functionality of the functions included in the apps, functional testing is done.To determine whether or not specific feature stability with the overall product is viable, smoke testing is done.
Integration testing is done to make sure the new module integrates logically with the application as a whole and that communication is easy throughout the entire process. Regression testing is done to make sure there are no conflicts by testing new code that impacts the application’s present functionalities.
Q. What is a framework for automated testing?
Ans. A program or piece of software that simplifies the automation process by adhering to best practices and guidelines is called an automation testing framework. To support the testing, this framework includes multiple functional libraries, object specifics, methods, test data sources, and reusable models.
Q. What is the benefit of using automated testing frameworks?
Ans. Frameworks for automated testing enhance the procedure in many ways. Reliability and consistency in achieving goals and aids in implementing consistent testing across the entire system. Big, complicated code is simple to manage and able to include fresh cases.
Q. Which situations are good and bad choices for automation testing?
Ans. For situations like massive data sets, smoke testing, regression test cases, repetitive operations, etc., automation is excellent. While ad hoc testing, exploratory, random, individual test cases, applications that change often, ad hoc testing, and user interface testing are all inappropriate use cases for automation testing. The selection of automation testing is heavily influenced by time and ROI (Return on Investment).
Q. Will automated testing eventually take the place of manual testing?
Ans. The entire testing process involves both manual and automated testing, both having advantages and disadvantages. Despite its additional advantages, automated testing is still not a viable substitute for manual testing because of its limitations in a number of cases.
Automated testing excels in repetitive tasks, regression testing, and scenarios with well-defined inputs and expected outputs. However, it falls short in areas requiring human intuition, creativity, and adaptability. Automated testing may struggle with exploratory testing, usability evaluation, and cases where unpredictable inputs or complex scenarios are involved.
Human testers bring a unique perspective, being able to uncover nuanced issues that automated scripts might overlook. Therefore, despite the additional benefits provided by automated testing, it is not a viable substitute for manual testing in all circumstances. A balanced approach that combines both methods ensures a more thorough and effective testing process.
Q. Which of the most widely used tools would you choose for automated testing?
Ans. Depending on the needs of the program as a whole, the industry uses a variety of automation tools, including Selenium, Appium, SoapUI, etc.
Q. Is it possible for us to get 100% automation in any situation?
Ans. Almost no testing technique can be implemented with 100% automation. Because certain real-world situations exist, such as the use of captcha matching to distinguish between humans and bots or the need to verify the screen’s background, certain jobs have become more labor-intensive. In some circumstances, manual testing is better. In any event, using 100% automation is generally not advised.
Q. Who ought to be in charge of automating tests? QA analysts or developers?
Ans. The team is responsible for creating web pages, executing processes, and managing test scripts on servers. They are a single unit entrusted with producing software that meets high standards. For automation testing to be done correctly, developers and quality assurance specialists should collaborate and draw on each other’s strengths.
Q. What is Selenium? What are its benefits and drawbacks?
Ans. Selenium is a well-known web automation technology that helps with cross-browser testing and browser automation.
