What Is a QA Engineer? Role, Skills and Career Path

Last updated: 11 October 2026 · By the Asuraa Team

Quick answer: A QA engineer ensures software works as intended by designing test cases, testing manually and with automation tools such as Selenium or Playwright, reporting defects and running regression before releases. Freshers in India usually need testing fundamentals, one programming language, SQL and API testing basics. ISTQB's Foundation Level (CTFL v4.0) exam, a common optional credential, has 40 questions in 60 minutes and needs 26 marks to pass.

Key takeaways

• A QA engineer designs tests, runs manual and automated checks, reports defects and helps prevent bugs by reviewing requirements early.
• ISTQB's CTFL v4.0 exam has 40 questions, a 60-minute duration and a pass mark of 26 out of 40, with 25% extra time for non-native language candidates.
• Selenium WebDriver drives browsers through vendor-provided automation APIs, while Playwright supports Chromium, Firefox and WebKit from TypeScript, Python, .NET and Java.
• Only 0.8% of Stack Overflow Developer Survey 2025 respondents chose 'Developer, QA or test' as their role.
• QA careers branch into test lead and QA manager roles or into SDET, test architect, DevOps and development roles for strong automation engineers.

What is a QA engineer?

A QA (quality assurance) engineer makes sure software works as intended before and after it reaches users, by designing tests, running them manually or through automation, reporting defects and helping the team prevent bugs in the first place. In Indian IT services companies, product startups and global capability centres, the role is also called test engineer, software tester, SDET (software development engineer in test) or automation engineer, depending on how much coding it involves.

Quality assurance is broader than testing. Testing finds defects in a build; QA also covers the process around it, such as reviewing requirements for ambiguity, agreeing on acceptance criteria, and deciding which tests must pass before a release goes out.

What does a QA engineer do day to day?

A QA engineer spends most of the day understanding what a feature should do, checking whether it does, and communicating clearly when it does not. Typical work includes:

• Reading user stories and requirements and asking questions where they are unclear.
• Writing test scenarios and test cases, including edge cases and negative cases.
• Running manual tests on web and mobile builds across browsers and devices.
• Logging defects in a tracker such as Jira with clear steps, expected and actual results, and screenshots or logs.
• Writing and maintaining automated tests for regression suites.
• Testing APIs with tools such as Postman, and checking data in the database with SQL.
• Re-testing fixes and running regression before each release.
• Taking part in daily stand-ups and sprint reviews in agile teams.

What skills does a QA engineer need?

You need a tester's mindset first, then technical skills that grow with the role. Freshers are usually hired on testing fundamentals plus basic programming and SQL; automation depth determines how fast you progress.

On automation tools, two names dominate. The Selenium project describes itself as an umbrella of tools and libraries for automating web browsers, with WebDriver controlling the browser through the automation APIs that browser vendors provide. Playwright, a newer framework, supports Chromium, Firefox and WebKit and can be used from TypeScript, Python, .NET and Java. Learn one well; the concepts transfer. Our guide on learning Selenium for testing jobs gives a structured plan.

Is ISTQB certification required to become a QA engineer?

No, but it is a recognised way to show you know testing vocabulary and fundamentals, and some Indian services companies and clients value it. According to ISTQB, the Certified Tester Foundation Level (CTFL) v4.0 exam has 40 questions, lasts 60 minutes (with 25% extra time for candidates taking it in a non-native language), and requires 26 out of 40 points to pass. CTFL is also the prerequisite for ISTQB's higher-level certifications.

Treat CTFL as a structured way to learn the fundamentals, not as a job guarantee. Interviewers will still ask you to write test cases for a login page or a payment flow on the spot.

How do you become a QA engineer in India?

Build testing fundamentals, add one programming language and one automation tool, and prove it with a public project. A practical path:

1. Learn testing fundamentals: levels (unit, integration, system, acceptance), types (functional, regression, smoke, performance, security basics) and techniques such as boundary value analysis and equivalence partitioning.
2. Practise manual testing on real sites: pick a public demo application and write 30 to 50 test cases with clear steps and expected results.
3. Write good defect reports for issues you find, with reproduction steps and evidence.
4. Learn one language: Java and Python are common in Indian automation roles; JavaScript or TypeScript pairs well with Playwright.
5. Automate a regression suite for the same demo app with Selenium or Playwright, using the page object pattern.
6. Add API tests using Postman or a code library, and validate responses and status codes.
7. Learn SQL to verify data, and Git to manage your test code.
8. Run your tests in a CI pipeline, for example GitHub Actions, and publish the repository with a clear README.
9. Optionally take ISTQB CTFL to formalise your fundamentals.

What is the career path for a QA engineer?

The usual progression runs from QA engineer or test engineer to senior QA, then into test lead or QA manager on the people side, or SDET and test architect on the technical side. Strong automation engineers also move into DevOps, site reliability or development roles, because they already write code, work with CI pipelines and understand the system end to end.

What do most guides on QA engineering get wrong?

They describe QA as an easy, non-coding entry into IT that you can later "upgrade" from. That framing hurts candidates. Modern QA roles increasingly expect automation, API testing and CI skills, and pure manual roles tend to offer slower growth. If you choose QA, choose it for the work itself and plan to code.

The opposite mistake is also common: assuming automation replaces manual thinking. Automated suites only check what someone thought to test. The value of a good QA engineer is in designing the right tests, exploring the product like a curious user and spotting risk early. Tools change; that judgement does not.

A final nuance: dedicated testers are a small share of the global developer community. Only 0.8% of respondents in the Stack Overflow Developer Survey 2025 chose "Developer, QA or test" as their role. That partly reflects who answers developer surveys, but it also means a tester who can code clearly stands out. If you are torn between testing and development, our comparison of manual testing versus a development career lays out both paths honestly.

How should a fresher show QA skills on a resume?

Show evidence, not just tool names. Link your GitHub test automation project, mention how many test cases you wrote and what they covered, and describe one interesting defect you found and how you reported it. Mirror the job description's terms, such as "regression testing", "API testing" or "Selenium WebDriver", so ATS filters match you. You can check the match against a specific posting with the Asuraa resume reviewer.

FAQ

What does a QA engineer do?

A QA engineer checks that software works as intended. They review requirements, write test cases, run manual and automated tests, log defects with clear reproduction steps, re-test fixes and run regression before releases. Many also test APIs, verify data with SQL and maintain automated suites that run in CI pipelines, working closely with developers and product managers in agile teams.

Is QA engineering a good career for freshers in India?

It can be, if you enjoy finding problems and are willing to learn automation. Many Indian services companies, startups and GCCs hire freshers into testing roles. Growth is faster for testers who code, because automation, API testing and CI skills lead to SDET, test architect, DevOps or development roles. Purely manual roles tend to progress more slowly.

Do QA engineers need coding skills?

For most modern QA roles, yes. Manual testing roles exist, but automation engineers and SDETs write test code in Java, Python, JavaScript or TypeScript using tools such as Selenium or Playwright. Even manual testers benefit from SQL for data checks and basic scripting. Learning one language well makes you much more employable and opens a clearer growth path.

Is ISTQB certification necessary for a QA job?

No. It is optional, but some employers and clients value it as proof of testing fundamentals. The ISTQB CTFL v4.0 exam has 40 questions in 60 minutes, and you need 26 out of 40 to pass. Interviews will still test practical skills such as writing test cases for a given feature, so combine the certificate with a portfolio project.

Selenium or Playwright: which should a fresher learn?

Either works; the testing concepts transfer. Selenium is long established and widely mentioned in Indian job postings, often with Java. Playwright is newer, supports Chromium, Firefox and WebKit, and works with TypeScript, Python, .NET and Java. Check which tool appears more in the postings you target, learn it deeply, and understand the other at a basic level.

What is the difference between QA and testing?

Testing is the activity of executing software to find defects. Quality assurance is broader: it includes testing but also covers the process that prevents defects, such as reviewing requirements, defining acceptance criteria, setting release quality gates and improving how the team works. In practice, Indian job titles often use QA engineer and test engineer interchangeably.
