CTAL-ATT Exam Dumps : Certified Tester Advanced Level Agile Technical Tester

A deterministic unit test is one that produces the same results every time it is run under the same conditions. This characteristic is crucial for unit tests because it ensures that the tests are reliable and that their results are repeatable. Deterministic tests help in identifying when a change in the codebase has introduced a defect, as any variation in the test outcome can be attributed to the change rather than an unpredictable test behavior12.

References = The ISTQB Advanced Level Agile Technical Tester syllabus and study resources emphasize the importance of deterministic behavior in unit tests as part of ensuring test reliability and effectiveness34.

Purpose of Test Case Refactoring:

Refactoring focuses on improving the structure of test cases without changing their behavior.

Key Verification After Refactoring:

Tests must produce the same results as before to confirm that refactoring has not altered functionality or introduced defects.

Analyzing the Options:

A: Branch coverage may change during refactoring, but consistent results are the primary focus.

B: Improved logging is desirable but not a critical verification.

D: Redundant test removal is unrelated to verifying unchanged behavior.

References:Aligned with ISTQB principles emphasizing consistency in test results after refactoring.

FIRST Acronym in Unit Testing:

Fast: Unit tests should execute quickly.

Isolated: They should run independently of other tests.

Repeatable: Tests should yield consistent results under the same conditions.

Self-validating: Results should indicate a pass or fail automatically.

Thorough: Each test should comprehensively cover the targeted functionality.

Analyzing the Options:

A: Incorrect terms such as "Iterative" and "Tolerant" are unrelated to unit tests.

C: Includes terms like "Recorded" and "Source-controlled," which do not align with FIRST.

D: Terms like "Immediate" and "Transparent" are unrelated to unit testing principles.

References:Aligned with ISTQB Agile Technical Tester syllabus defining unit test characteristics using the FIRST acronym.
