11+ Test Automation Engineer Interview Questions

We’re all human and make mistakes. Software development is nothing like that. There is always the possibility of trying to introduce bugs into the system, no matter how careful users are and when writing code.

This, however, can be seen as an explanation when it comes to delivering apps to customers. 

To ensure the highest system performance, a process is needed between design and testing. 

The method of discovering bugs and errors in software is called software checking. Its goal is to give stockholders enough trust to discharge the apps to clients.

In general, software testing can be divided into two broad categories: stick shift testing and test automation.

Both manual and test automation have benefits and drawbacks. To deliver high-quality apps, a good health software design organization employs both of these methods.

This article discusses the important queries that an application tester interviewer may ask. Its main emphasis is on automation testing. We’ve divided the questions into two groups: beginner and progressed.

What is meant by automation testing?

Automation testing is a testing tactic in which testing keeps running the tests algorithmically that used a tool or framework rather than manually going thru the tests and implementing them one by one.

The main objective of test automation is to save time, hard work, and money on repeated, infrequently changing tests.

Automation testing assists teams and organizations in automating testing efforts, and reducing. this needs human involvement and achieving higher speed, reliability, and efficiency. 

Also, it helps to shorten the development time because developers receive instant feedback. it can make changes quickly.

What are the types of automation testing?

There are various testing techniques, but not all of them can be automated. Consider test automation. Here are a few testing methods that can be automated.

 Unit tests: This is written by software engineers to test a single unit of code.

Integration tests are used to determine well how various software parts relate to one another.

Regression tests are used to make sure that the new code did not disrupt any existing features.

Performance tests ensure that the application will not crash and will perform adequately under a huge workload or strict conditions.

UI tests: Make software provides a consistent customer experience and that no visual or graphical components on the computer monitor are broken.

What is a good time to automate the test?

  • Under the following criteria, a test is a good contender for automation.
  • The test can be repeated.
  • The tested feature’s behavior does not change frequently. 
  • It takes time for a human analyzer.
  •  The test necessitates complex calculations.
  •  The test ensures that the previous capabilities did not break as a result of the new transformation.

When do you automate testing?

While automation has its benefits, it is not a great idea to computerize all of your tests. Here are some situations in which a human tester can outperform a test automation package in terms of software testing.

The software or highlight under test changes on a regular basis. 

It implies that you must frequently update their test automation in order to keep them fully updated. Tests can soon disappear and cease to be useful.

Exploratory testing is also not appropriate for test automation. A human tester can investigate software much more thoroughly than a computer.

Unless the test suites are coded or designed to look for User experience issues, they will not find any. A sentient tester is far more effective at detecting UI discrepancies or design flaws.

How do you choose the automated tool?

You must rely on software tools or structures to perform automation testing. There are lots of choices from which to choose.

Here are a few criteria to consider when evaluating these tools.

Tools that can be programmed (code-based) or that do not need to be programmed. Some tools necessitate programming knowledge, while others do not, allowing a quasi-tester to generate test scenarios with visual aid.

You should make your strategic initiatives on your team’s experience and expertise set.

Open Source vs. Commercial. The pricing of the tools varies greatly depending on the features they have. 

Software applications can be costly, but you get technical support when you need it. Although the open-source app is free, you must conduct research once troubleshooting issues.

The ease of use. Some test automation tools are notoriously difficult to use and necessitate specialized training before they can provide any value. Some are simple to use and can be used right away.

Selenium, Katalon Studio, UFT, TestComplete, Testim, and others are among the most famous automation tools. Consider the testing procedures for your project, discuss your team, as well as evaluate their skills, encounter, and solace with the tool once selecting one.

You also should evaluate the tool’s financial return on a regular basis and be prepared to change if necessary.

What is the different type of making test automation?

An automated test framework simplifies automation going to test for your software. The following are among the elements of an automated test framework.

Management of Test Data

The generation of test data is a significant issue in automation testing. A good test automation structure makes it simple to generate test data for the application being tested.

Libraries for Testing

The management and execution of automated tests is a critical components of any test automation strategy. An automated test framework includes libraries that simplify test governance.

Unit tests, integration, and system, as well as end-to-end tests, are all supported by a good automated test structure.

Testing Tools include any graphical user interface (GUI) or control tools that make it easy for the testing team to run a series of exams repeatedly. 

It also includes tools for performing performance analysis on apps under high load.

Should you make automate testing?

Although test automation has benefits, it is impractical to automate all types of testing. 

Some tests, such as user experience testing, usability testing, and ease of access running tests, can only be performed by a human tester.

Another level of assessment in which a human tester adds more significance than an independent test is explorative testing. 

In the testing process, a tester randomly uncovers this same software. so as a finished would, in order to find bugs, UI discrepancies, or hidden troubles that devs may have neglected.

Automated testing is useful for big projects involving complex calculations and for new tests that can be repeated. 

A human tester provides a higher ROI than automated processes for characteristics. It changes frequently and rarely implemented test cases.

What is the test environment?

A test environment is a desktop or a server where software is tested. After the team completes the software development, the tester installs it on this desktop. 

Along with all of its interconnections, in the same manner as the production environment. This enables the tester to put the software through its paces in a real-life setting.

A test environment that enables the test to check to create consistent test setups when a fresh version of the application comes released. 

The test environment includes the testing ground. It would be the data set on which the apps will be tested by the tester. This setting clears the tester from invalidating test cases that require a specific setup.

The testing environment is typically a carbon copy of the production system. Having two copies allows this same tester to reliably regenerate the bugs noted by clients. 

  • It provides the designers with the exact stages to fix them.
  • The following are some requirements for a good testing environment:
  • A client with a comparable configuration, such as the operating systems required for a manufacturing environment.
  • Test data samples will be used to put the software through its paces.
  • It can be dull Browser automation is the process of algorithmically launching a web service in a browser and performing various actions in the same way that a regular user often does.

What do you mean by browser automation?

Browser testing provides you with the speed and accuracy that a human tester would not be able to achieve. Some common tools for in-browser test results include Protractor, Coniferous, and Selenium.

The following are among the activities carried out by the browser automated process of an actual manufacturing database or a test data system with fairly realistic data.

  •  Under exam, software was installed.
  •  Navigate to the user’s URL and ensure that it starts.
  •  Check to see if any of the links on the website are broken.
  • Make a note of any redirects on the page.
  •  Test the load and achievement of your web service.
  •   Launch run multiple occurrences with various testing users. verify that simultaneous actions work properly.

What is cross-testing browsing?

You never know which browsers consumers will use when developing web applications. As a result, it is critical to test the internet app or software on various big web pages running in a Linux environment.

A Cross-browser test is a type of internet explorer automation testing in which the tester confirms that the web service works properly across multiple browsers. 

Web Browser, Mozilla, Internet Explorer, Safari, and other popular web browsers are listed below.

The goal of cross-browser test results is to release the implementation on multiple browsers trying to run on multiple operating systems, such as Windows, Mac OS, Linux, and so on, and ensure that it performs as intended. 

The tester makes it look for design/rendering issues, desktop applications, and gadget capabilities.

Though it is not always the case, sophisticated technology exists that enables testing to computerize cross-browser laboratory tests. Selenium Box, BrowserStack, Browsershots, LambdaTest, and other tools are examples.
