Manual Testing in Agile: How QA Fits into Sprints and Scrum
In the fast-paced world of Agile software development, the role of Quality Assurance (QA) is often misunderstood. Some believe that with rapid iterations and continuous delivery, manual testing becomes obsolete, replaced entirely by automation. However, the reality is quite the opposite. Manual testing in Agile remains a critical, irreplaceable discipline that ensures the human perspective on quality, usability, and functionality is never lost. This blog post will explore how QA professionals seamlessly integrate into the Agile QA process, specifically within Scrum testing frameworks and sprint testing cycles, to deliver high-quality software that truly meets user needs.
Key Insight: A 2023 report from the State of Agile found that 71% of organizations practice Agile development. Within these teams, effective QA integration is consistently cited as a top-3 factor for project success, highlighting that testing is not a phase but a continuous activity.
The Agile QA Mindset: From Gatekeeper to Collaborator
The traditional "waterfall" model often positioned QA as a final gatekeeper, testing a complete product before release. Agile flips this script. In Agile, QA is a proactive collaborator embedded within the cross-functional team from day one. The goal shifts from "finding bugs" to "preventing defects" and advocating for quality at every step of the development lifecycle.
Core Principles of Agile QA
- Shift-Left Testing: Testing activities begin as early as the requirement gathering and design phase. QA analyzes user stories for testability and clarity during backlog refinement.
- Continuous Feedback: QA provides immediate feedback to developers on build quality, functionality, and design, enabling rapid fixes within the same sprint.
- Whole-Team Responsibility: While QA specialists lead the testing effort, quality is a shared responsibility. Developers write unit tests, and product owners define clear acceptance criteria.
- Value-Driven Testing: Focus is on testing business value and user experience, not just technical compliance. Exploratory testing becomes a key tool.
Mapping the QA Role to Scrum Ceremonies
Scrum, the most popular Agile framework, provides a structured yet flexible rhythm of events. Here’s how a manual QA engineer actively participates in each:
Sprint Planning
QA is crucial in helping the team assess the testing effort for each user story. They ask critical questions: "Are the acceptance criteria testable?", "What are the edge cases?", "Do we need specific test data?" This collaboration ensures stories are properly sized and the sprint backlog is realistic.
Daily Stand-ups
Beyond stating what they tested yesterday, a proactive QA engineer reports:
- Blockers preventing test execution (e.g., environment issues).
- Status of the current build's stability.
- Collaboration needs with developers for bug verification or clarification.
Sprint Review & Retrospective
In the review, QA demonstrates working software from a user's perspective, not just a checklist. In the retrospective, they contribute insights on what improved or hindered quality during the sprint, suggesting process improvements for the next cycle.

The Manual Testing Workflow Within a Sprint
A typical two-week sprint sees a rhythmic and integrated flow of testing activities. This sprint testing cycle is continuous, not a single event.
Week 1: Preparation and Early Execution
- Day 1-2 (Sprint Start): Develop test charters and mind maps for high-priority stories. Set up test data and environments. Begin testing stories as soon as they are marked "Dev Complete."
- Day 3-5: Execute structured test cases based on acceptance criteria. Perform initial exploratory testing on features. Log defects and work closely with developers for immediate resolution.
Week 2: Deep Validation and Closure
- Day 6-8: Conduct in-depth integration and regression testing. Focus on user workflow and end-to-end scenario validation.
- Day 9-10 (Sprint End): Perform "sprint closure" testing: a final round of smoke and sanity testing on the release candidate. Ensure all acceptance criteria are met and critical bugs are closed. Prepare demo data for the sprint review.
Essential Manual Testing Techniques for Agile Teams
Agile's iterative nature demands testing techniques that are both efficient and deeply insightful.
Exploratory Testing (ET)
This is the superpower of the manual tester in Agile. ET is simultaneous learning, test design, and execution. Testers explore the application without rigid scripts, using their domain knowledge and creativity to uncover bugs that scripted tests miss. It’s perfect for testing new features quickly within a sprint's timebox.
Session-Based Testing
This brings structure to exploratory testing. Testers work in focused, uninterrupted timeboxes (e.g., 90-minute sessions) with a specific charter ("Explore the new checkout flow as a first-time user"). Results are debriefed, providing measurable output from unscripted testing.
Acceptance Test-Driven Development (ATDD) Collaboration
QA works with the Product Owner and developers to define acceptance criteria for a user story in a testable format (often as "Given-When-Then" scenarios). These criteria become the foundation for both development and testing, ensuring everyone shares the same definition of "Done."
Overcoming Common Challenges in Agile QA
Despite its benefits, integrating manual testing in Agile presents unique hurdles.
- Challenge: "Testing Time is Crunched." Solution: Advocate for testability during story refinement. Use risk-based testing to prioritize. Leverage lightweight documentation like checklists over heavy test cases.
- Challenge: "Constantly Changing Requirements." Solution: Embrace change. Use flexible testing techniques like ET. Maintain close communication with the PO to understand the "why" behind changes.
- Challenge: "Incomplete or Unstable Builds." Solution: Work with developers on a "definition of ready." Use feature toggles to test incomplete features. Focus on testing stable components first.
Collaboration Strategies for QA, Dev, and PO
The heart of successful Scrum testing is the "Three Amigos" principle: Business (Product Owner), Development, and QA.
- Backlog Refinement Meetings: All three amigos discuss upcoming stories. QA provides input on testability, edge cases, and acceptance criteria.
- Pair Testing: A QA engineer and developer test a feature together at one workstation. This facilitates instant feedback, knowledge sharing, and faster root-cause analysis.
- Bug Triage: Quick, daily discussions on newly logged defects to assess severity, assign priority, and decide on fix timelines without leaving the sprint flow.
To excel in Agile, QA professionals need both manual expertise and automation awareness. Our comprehensive Manual and Full-Stack Automation Testing course equips you with the hybrid skill set modern teams demand, teaching you how to balance rapid manual validation with strategic automation in a sprint cycle.
Conclusion: The Indispensable Agile QA
Manual testing in Agile is not a relic; it's a dynamic, intellectually demanding, and collaborative practice. The Agile QA engineer is the user's advocate, the critical thinker, and the quality coach within the team. By integrating testing into every sprint, employing smart techniques like exploratory testing, and fostering deep collaboration, QA ensures that the fast pace of Agile does not come at the cost of quality. In the end, successful Agile teams don't see QA as a separate function—they see quality as the collective output of a unified team working in harmony across all Scrum testing activities.
Frequently Asked Questions (FAQs) on Agile Manual Testing
Absolutely. Automation excels at regression, repetition, and speed. Manual testing is irreplaceable for evaluating user experience, visual appeal, usability, and performing ad-hoc/exploratory testing. Agile teams use a balanced "hybrid" approach where automation handles the predictable and manual testing investigates the complex and subjective.
QA estimates based on: Complexity of acceptance criteria, number of test scenarios and data combinations, integration points with other features, and the need for exploratory testing. Techniques like "Testing Poker" (similar to Planning Poker) or breaking down tasks (test design, execution, bug verification) into hours are common. Historical data from similar stories is the best guide.
The QA engineer typically owns test design. However, the trend is towards lightweight, living documentation. Instead of lengthy, rigid scripts, Agile teams favor:
- Checklists derived from acceptance criteria.
- Mind maps for test coverage.
- Executable specifications (like Gherkin).
- Detailed scripts are reserved for complex, high-risk, or regulatory-required functionality.
The team (PO, Dev, QA) assesses it immediately. Options include:
- Fix it in-sprint: If there's capacity and it doesn't jeopardize other commitments, the developer fixes it, and QA re-tests.
- De-scope the story: If it can't be fixed in time, the PO may decide to remove the story from the sprint and bring it back later. The sprint goal may need to be re-negotiated.
- Carry-over: Rarely, the entire story (now fixed) is carried to the next sprint, but this is discouraged as it breaks the sprint boundary.
It's a combination of strategies:
- Automated Regression Suite: The backbone. Run nightly or on every build to catch functional regressions quickly.
- Manual Smoke/Sanity Testing: A focused 30-60 minute test on the new build to ensure stability for further testing.
- Risk-Based Regression: Manual testers focus regression efforts on areas most likely impacted by the current sprint's changes.
- End-of-Sprint Regression: A broader, but still time-boxed, manual test of core user journeys before the sprint review.
Be a vocal participant in retrospectives. Suggest improvements like: "Let's improve our Definition of Ready to avoid ambiguous stories," or "Can we allocate 30 minutes for pair testing complex features?" Track metrics like "Bug Escape Rate" or "Time to Test" to provide data-driven insights into process bottlenecks.
In Scrum, work is time-boxed into sprints with a fixed goal. QA activities are planned per sprint, and there's a regular rhythm of ceremonies. In Kanban, work flows continuously. QA pulls the next ready story from the "To Test" column. There are no sprints, so testing is ongoing. The core QA mindset of collaboration and shift-left remains the same, but the workflow cadence differs.
Focus on mindset shift first: from phase-based to continuous, from gatekeeper to partner. Develop skills in exploratory testing, writing acceptance criteria, and using Agile project management tools (Jira, Azure DevOps). Start by advocating for involvement in early requirement discussions. Consider formal training, such as our Manual Testing Fundamentals course, which bridges traditional and modern practices.
