Before Quality Assurance (QA) automation, manual testing was done using some tech that reduced repetition. With QA automation, we can use separate software to smoothly and quickly run tests on the software we’re developing. In this article, we’ll explore some QA automation interview questions to help you prepare for your tech interviews!

If you are preparing for a tech interview, check out our technical interview checklist, interview questions page, and salary negotiation ebook to get interview-ready! Also, read Amazon Coding Interview Questions, Facebook Coding Interview Questions to Nail Your Next Interview, and Google Coding Interview Questions for specific insights and guidance on Coding interview preparation.

Having trained over 9,000 software engineers, we know what it takes to crack the most challenging tech interviews. Since 2014, Interview Kickstart alums have landed lucrative offers from FAANG and Tier-1 tech companies, with an average salary hike of 49%. The highest ever offer received by an IK alum is a whopping $933,000!

At IK, you get the unique opportunity to learn from expert instructors who are hiring managers and tech leads at Google, Facebook, Apple, and other top Silicon Valley tech companies.

QA Automation Testing Interview Questions and Answers

Let us jump right into some sample QA automation testing interview questions and answers to get an idea of what to expect in QA automation interview questions:

Q1: When should we prefer to automate a test? 

We should prefer to automate a test if: 

  • It’s a repetitive task
  • We need to run the tests with multiple data sets
  • There are regression test cases or smoke and sanity tests that warrant it
  • After automation, the ROI (Return on Investment) is good enough for us to do so.

Q2: When should we prefer not to automate a test? 

We should prefer not to automate if:

  • The Application we need to test changes frequently
  • Most test cases are one-time test cases
  • There’s Adhoc or random testing

Q3: What are the primary features of a quality automation tool?

Some features of a good automation tool are:

  • Test Environment support
  • Easy to use
  • Good debugging facility
  • Multiple frameworks support
  • Object and Image testing facilities
  • Robust object identification
  • Object identification
  • Database testing

Q4:  What are the four framework types used in software automation testing?

The four types of automation frameworks used in software automation testing are:

  • Keyword-driven 
  • Data-driven 
  • Modular
  • Hybrid 

Q5: What are the steps involved in the Automation Process?

The automation process steps include:

  • Test tool selection
  • Automation scope definition
  • Planning
  • Design
  • Development
  • Test execution
  • Maintenance

Q6: Why do we need QA automation?

Automating routine tasks and executing test cases multiple times, in multiple devices, at a large scale becomes easily doable with the help of QA automation. QA automation makes a QA team far more efficient and powerful.
