What is test efficiency?

Test efficiency measures how well a testing process finds defects while using minimal time, effort, and resources. It shows how testing activities boost software quality and help meet delivery deadlines.

Do you have any examples of test efficiency?

Test efficiency uses metrics like defects found per test case, execution time, and defect leakage rate. For instance, if a team runs 100 test cases and finds 80 defects, the test suite's efficiency depends on how it uncovered these issues with minimal effort and without redundant tests.

Why is test efficiency important?

Test efficiency helps teams optimize testing strategies, cut unnecessary work, and maximize defect detection. Efficient testing creates faster development cycles, reduces costs, and makes software more reliable.

What are the challenges of improving test efficiency?

Challenges include finding the right balance between speed and quality, eliminating redundant tests, and achieving good coverage without excessive runtime. Poor test design and ineffective automation hurt efficiency. Teams improve efficiency through regular monitoring, refined test strategies, and smart automation tool use.
