Fixed Sample Testing vs Adaptive Testing
Developers should use Fixed Sample Testing when conducting controlled experiments, like A/B tests for feature rollouts or performance optimizations, to avoid biases from early stopping and ensure results meet predefined statistical standards meets developers should learn adaptive testing to improve test coverage and reduce time-to-market in agile or continuous integration/continuous deployment (ci/cd) environments, where frequent code changes require rapid feedback. Here's our take.
Fixed Sample Testing
Developers should use Fixed Sample Testing when conducting controlled experiments, like A/B tests for feature rollouts or performance optimizations, to avoid biases from early stopping and ensure results meet predefined statistical standards
Fixed Sample Testing
Nice PickDevelopers should use Fixed Sample Testing when conducting controlled experiments, like A/B tests for feature rollouts or performance optimizations, to avoid biases from early stopping and ensure results meet predefined statistical standards
Pros
- +It is particularly valuable in scenarios requiring regulatory compliance or when making high-stakes decisions based on data, as it provides clear stopping rules and reduces the risk of false positives
- +Related to: a-b-testing, hypothesis-testing
Cons
- -Specific tradeoffs depend on your use case
Adaptive Testing
Developers should learn adaptive testing to improve test coverage and reduce time-to-market in agile or continuous integration/continuous deployment (CI/CD) environments, where frequent code changes require rapid feedback
Pros
- +It is particularly useful for large-scale applications with complex dependencies, as it helps prioritize testing on critical components or recently modified code, enhancing defect detection while minimizing redundant tests
- +Related to: test-automation, continuous-integration
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Fixed Sample Testing if: You want it is particularly valuable in scenarios requiring regulatory compliance or when making high-stakes decisions based on data, as it provides clear stopping rules and reduces the risk of false positives and can live with specific tradeoffs depend on your use case.
Use Adaptive Testing if: You prioritize it is particularly useful for large-scale applications with complex dependencies, as it helps prioritize testing on critical components or recently modified code, enhancing defect detection while minimizing redundant tests over what Fixed Sample Testing offers.
