This invention discloses a test strategy adjustment method, apparatus, electronic device, and storage medium. The method includes: acquiring a defect trend curve of the module under test; analyzing the defect trend curve to determine its concavity / convexity; and adjusting the test strategy based on the concavity / convexity. This solves the problem of not being able to perform testing based on the actual implementation quality of the project during development. By analyzing defects that occur during testing, the test strategy can be reasonably adjusted, achieving dynamic adjustment of the test strategy during testing. This allows for better defect detection, timely adjustment of test strategies, optimization of test resource allocation, decoupling of testing experience from test quality, and making test quality more standardized.
