What Is a Manual QA Tester: Roles, Skills, and Career Path

What Is a Manual QA Tester?

A manual QA tester is a professional who performs manual testing, which means executing test cases without automation to ensure software meets functional, usability, and performance requirements.

They design test scenarios, verify acceptance criteria, and maintain test artifacts like test cases, bug reports, and traceability matrices. Manual testers collaborate with developers and stakeholders to clarify requirements, perform regression testing and exploratory testing, and ensure software quality before release.

What Does a QA Manual Tester Do?

A QA manual tester creates and runs test cases, identifies and tracks defects. They verify fixes and document results to ensure software meets requirements and works as expected.

Here are the responsibilities of a manual QA tester:

• Test Planning and Analysis: The tester reviews functional and non-functional requirements to identify testable components. A test strategy is created, defining the scope, priorities, types of software testing, entry and exit criteria, resources, and timelines to ensure effective testing.
• Writing Test Scenarios and Test Cases: Requirements are translated into structured test scenarios and test cases with preconditions, execution steps, expected results, and postconditions. Best practices include maintaining traceability, grouping tests by module, and using templates to ensure consistency and coverage.
• Test Execution: Test cases are executed for functional, system, integration, and regression testing. Exploratory testing is used to uncover defects beyond predefined scenarios. Actual results are compared against expected results, and deviations are noted for analysis.
• Defect Management: Defects are logged with reproduction steps, severity, and expected versus actual behavior. They are classified, tracked, and monitored using tools like Jira until resolution. Collaboration with development teams ensures accurate defect verification.
• Reporting and Documentation: Test execution is documented, and regular status updates are provided. Daily logs include executed tests, defects identified, and any blocked scenarios. Test reports consolidate coverage, defect trends, risk areas, and release readiness recommendations.

What Are the Skills of a Manual Tester?

A manual software tester needs SDLC knowledge, manual testing, SQL, and defect tools. They also need analytical thinking, attention to detail, communication, problem-solving, teamwork, and adaptability.

Here are the essential skills every QA manual tester should have:

Key Technical Skills:

• SDLC and Testing Methodologies: Understanding software development and testing life cycles, including functional, regression, integration, and performance testing, ensures structured, consistent, and aligned testing.
• Manual Testing Principles: Knowledge of test case design, planning, exploratory testing, and structured execution forms the foundation of effective QA work.
• Test and Defect Management Tools: Proficiency in bug tracking tools like Jira or Bugzilla enables efficient test planning, bug logging, tracking, and collaboration with development teams.
• SQL and Database Testing: Basic SQL knowledge allows verification of backend data integrity and accurate application-database interactions during functional testing.

• Agile and Waterfall Models: Familiarity with SDLC models allows integration of testing within iterative and linear workflows, supporting continuous collaboration and quality assurance.
• User-Focused Testing: Evaluating software from an end-user perspective helps identify usability issues alongside functional correctness.

Key Soft Skills:

• Analytical Thinking: Ability to analyze complex software, interpret test results logically, and identify defects efficiently.
• Attention to Detail: Detecting subtle defects, inconsistencies, and UI bugs requires methodical observation and precision.
• Communication: Clear reporting of defects, test progress, and risks to developers, QA leads, and stakeholders facilitates prompt resolution.
• Problem-Solving: Identifying failures and root causes, and recommending solutions ensures defects are effectively addressed.
• Team Collaboration: Working with cross-functional teams, providing constructive feedback, and aligning with project goals supports quality delivery.
• Documentation Discipline: Maintaining detailed records of tests, defects, and test data ensures traceability and supports knowledge sharing.
• Time Management: Prioritizing tasks, managing coverage, and meeting deadlines ensures timely test execution within project schedules.
• Adaptability and Continuous Learning: Staying updated with new manual testing tools, techniques, and workflows supports evolving QA requirements and professional growth.

What Are the Best Manual Testing Tools for QA?

Top manual testing tools for QA are LambdaTest for cross-browser and real device testing, Jira for bug tracking, Slack for communication, Postman for API testing, and OWASP ZAP for security testing.

Here are some of the best manual testing tools every manual QA tester can use:

• LambdaTest: It is a cloud-based testing platform that allows teams to perform live testing (manual testing) of websites or mobile applications on real browsers, operating systems, and devices hosted on the cloud.

Features:

• Browser and OS Combinations: Run tests on multiple browsers and operating systems to ensure cross-platform compatibility.
• Real Device Cloud: Test websites and mobile applications on a real device cloud of Android and iOS devices to check functionality, compatibility and performance.
• Real-Time Debugging: Use built-in developer tools to inspect and troubleshoot issues during live test sessions.
• Project Management: Organize test sessions, switch between project versions, and save progress within the testing environment.

• Jira: Widely used issue and defect tracking system for logging bugs, managing workflows, monitoring status, and linking defects to requirements or test cases.
• Slack: Enables real-time communication of test updates, defects, and issues among QA, development, and project teams.
• Postman: Interface for manual API testing, enabling request construction, response validation, and environment configurations while documenting test interactions.
• ZAP (OWASP ZAP): A security-focused tool aiding in manual web testing by capturing and inspecting HTTP traffic, identifying common vulnerabilities during exploratory QA sessions.

How to Become a Manual QA Tester?

To become a manual tester, learn SDLC, manual testing, and basic HTML/CSS/SQL. Use manual testing tools, earn certifications, join communities and apply for entry-level tester roles.

Here’s a roadmap to begin a career as a manual QA tester:

• Understand Software Development Concepts: Learn how software is built and delivered, including the Software Development Life Cycle (SDLC) with a focus on Agile and Waterfall models. Understanding these frameworks helps coordinate testing with development tasks and timelines.
• Learn Manual Testing Fundamentals: Study testing types such as functional, regression, integration, and usability testing. Practice writing clear test cases, executing them accurately, and reporting defects in an organized manner.
• Build Basic Technical Skills: Gain foundational knowledge of HTML, CSS, HTTP protocols, and SQL. This understanding helps in verifying front-end functionality and validating backend data during testing.
• Gain Hands-On Experience: Apply knowledge gained through internships, open-source projects, or sample test cases for dummy applications. Focus on documenting tests, tracking bugs, and collaborating with developers.
• Get Proficient with QA Tools: Familiarize yourself with tools for test management, defect tracking, and cloud testing platforms such as LambdaTest for scalable testing.

For example, LambdaTest AI-native Test Manager helps teams handle growing test coverage by centralizing test cases and running them across multiple environments without maintaining local infrastructure.
