Peer Review in End-to-End Testing: Best Practices and Benefits

Peer Review in End-to-End Testing: Best Practices and Benefits

3 July 2024 Stephan Petzl Leave a comment QA

As end-to-end testers, the question often arises whether we should peer review the tests from other testers in our team. Developers frequently employ peer review processes, validating pull requests through team evaluations, which has proven beneficial. However, in the realm of testing, this practice is not always as common. Testing projects increasingly resemble other code projects, with reusable functions and complex logic, making peer reviews potentially valuable.

Why Peer Reviews Are Important in Testing

Peer reviews in testing are not just about code validation. They offer several critical benefits:

  • Identifying Improvements in Code Logic: Peer reviews can highlight potential enhancements in the logic of your test scripts.
  • Improving Test Coverage: Reviews can reveal missed application logic or more efficient testing approaches, ensuring comprehensive test coverage.
  • Solving Problems Efficiently: Collaborative reviews often uncover better methods to address testing challenges.
  • Learning Opportunities: Receiving feedback from peers can help overcome author bias and provide valuable learning experiences.

Practical Example

Consider an example from an initial coding experience. A tester focuses on validating error messages for invalid inputs in a payment system but misses verifying the payment process for all valid inputs. During a peer review, a colleague suggests testing the end-to-end flow for all valid inputs. This review reveals a corner case where the system fails, highlighting the importance of comprehensive test coverage.

Common Challenges and Solutions

Despite the benefits, several challenges can hinder the implementation of peer reviews:

  • Tight Budgets: Business constraints may limit the time available for reviews, even if it impacts long-term project quality.
  • Limited Resources: Small companies may lack sufficient testers to conduct reviews, or existing testers may be too busy with their own projects.
  • Organizational Issues: Agile teams might have only one tester per project, making it difficult to find knowledgeable reviewers.

Addressing these challenges requires organizational support and prioritization of quality assurance practices. Encouraging a culture of collaboration and continuous improvement can help overcome these barriers.

Best Practices for Effective Peer Reviews

To conduct effective peer reviews, consider the following best practices:

  • Clarity: Ensure each test clearly defines what it is testing and what it is not.
  • Readability: Write readable and understandable code, minimizing the need for extensive comments.
  • Maintainability: Design tests to be easily maintainable, allowing for efficient updates in response to application changes.
