Buddy Testing in Software Testing: Definition, Process, Benefits & Best Practices

Buddy Testing is a collaborative software testing technique where two team members—typically a developer and a tester—work together to evaluate a piece of software before it’s released. This approach is gaining renewed interest in today’s agile and DevOps-driven QA environments, where effective collaboration and rapid feedback loops are critical to success.

In this article, you’ll learn what Buddy Testing is, how it works, its advantages and disadvantages, how it differs from Pair Testing, and how you can implement it effectively—even in cloud-native, automated testing environments like TestResults.io.

What is Buddy Testing?

Buddy Testing is a type of software testing where two "buddies"—most often a developer and a tester—jointly test a feature, module, or application. The primary goal is to catch defects early by combining the developer’s knowledge of the code with the tester’s expertise in finding issues and thinking from a user’s perspective.

Key points:

• Involves two people working together (usually from different roles).
• Fosters knowledge sharing, reduces misunderstandings, and surfaces defects earlier.
• Typically performed before formal testing phases like system or acceptance testing.

Buddy Testing is a collaborative software testing method where two team members (often a developer and a tester) jointly test a software component to identify defects early and improve software quality.

Buddy Testing Process: How Does It Work?

Implementing Buddy Testing is straightforward, but following a structured process ensures maximum benefit:

1. Pair Selection: Assign a developer and a tester as buddies for a specific feature or module.
2. Preparation: Review requirements, user stories, and acceptance criteria together.
3. Joint Testing Session: Both buddies execute tests—one may operate the application while the other observes, asks questions, or suggests test scenarios.
4. Defect Logging: Any issues found are discussed and logged immediately, often with joint agreement on severity and priority.
5. Discussion & Knowledge Transfer: The developer explains technical implementation, while the tester brings user-centric insights.
6. Follow-up: Address defects or ambiguities before the code moves to formal QA or production.

Example workflow:

• A developer completes a new login feature.
• The developer and a QA tester schedule a Buddy Testing session.
• They walk through the login process, test edge cases, and review error messages together.
• Any bugs or usability concerns are discussed and logged on the spot.

Buddy Testing vs Pair Testing: Key Differences

While Buddy Testing and Pair Testing are both collaborative, they have distinct characteristics:

When to use each:

• Buddy Testing: Ideal for early feedback, bridging dev-QA gaps, and uncovering misunderstandings.
• Pair Testing: Useful for deep exploration, test case generation, or when training new testers.

Advantages and Disadvantages of Buddy Testing

Advantages:

• Early defect detection, reducing cost of fixing bugs.
• Improved communication between development and QA.
• Promotes shared ownership and understanding of requirements.
• Quick feedback loop, especially valuable in agile teams.
• Reduces misunderstandings and missed test scenarios.

Disadvantages:

• Can be time-consuming if not well managed.
• May not scale well for large teams or projects.
• Relies on good interpersonal dynamics; mismatched pairs may be less effective.
• Potential for groupthink if both buddies have similar perspectives.

Tip: Use Buddy Testing in combination with automated testing for broader coverage and efficiency.

Best Practices for Effective Buddy Testing

To maximize the impact of Buddy Testing, consider these best practices:

• Define clear objectives: Agree on what to test and what success looks like.
• Choose diverse buddies: Pair individuals with complementary skills and perspectives.
• Schedule sessions early: Integrate Buddy Testing before formal QA or release.
• Document findings: Log defects and insights immediately for traceability.
• Rotate pairs: Encourage knowledge sharing across the team.
• Leverage tools: Use collaborative platforms (like TestResults.io) to track sessions, defects, and test artifacts.

Real-World Examples and Use Cases

• Agile sprint reviews: Developers and testers buddy up to validate new features before sprint demos.
• Regulated industries: In healthcare or finance, Buddy Testing helps ensure compliance by combining technical and regulatory expertise.
• Remote/distributed teams: Cloud-native platforms allow buddies to collaborate and test together from anywhere.

How Buddy Testing Fits into Modern QA and Test Automation

Buddy Testing is not a replacement for automation, but a valuable complement—especially for catching issues that automated scripts may miss, such as usability, ambiguity, or edge cases.

Integrating with TestResults.io:

• Use TestResults.io’s cloud-native platform to host your Subject Under Test (SUT) and test environments, enabling remote Buddy Testing sessions.
• Store, track, and report on Buddy Testing outcomes alongside automated test results for full traceability.
• Benefit from versioned test execution and reporting—critical in regulated industries.

Conclusion

Buddy Testing enhances software quality by fostering collaboration between developers and testers, surfacing defects early, and promoting shared understanding. When combined with modern test automation platforms like TestResults.io, it can fit seamlessly into agile, regulated, and cloud-native workflows—making your QA process more robust and efficient.
