Study Notes

Functional System Testing

Functional system testing is testing the end-to-end functionality of the system as a whole.

Peer Reviews

Peer Reviews are also called Inspections.

State Transition Diagram

An invalid state transition is from FAULT to ON.

Code Coverage

100% statement coverage does not guarantee 100% branch coverage.
100% branch coverage guarantees 100% decision coverage.
100% decision coverage does not guarantee 100% branch coverage.

Kick-Off Phase

The Kick-Off phase of a formal review includes explaining the objective.

Software Development Life Cycle

Hi-level design corresponds to Unit tests.
Code corresponds to Acceptance tests.
Low-level design corresponds to System tests.
Business requirements correspond to Integration tests.

Fundamental Test Process

The phases of the Fundamental Test Process are Test Planning and Control, Test implementation and Execution, and Evaluating Exit criteria and reporting.
Requirement Analysis is not a phase of the Fundamental Test Process.

Black Box Techniques

State transition testing is a black box technique.
Boundary value analysis is a black box technique.
LCSAJ (Linear Code Sequence and Jump) is not a black box technique.

Success Factors for Review

Success factors for a review include management supporting a good review process and an emphasis on learning and process improvement.
Defects found are welcomed and expressed objectively.

Defects Discovered by Static Analysis Tools

Defects discovered by static analysis tools include variables that are never used, security vulnerabilities, programming standard violations, uncalled functions, and procedures.

Test Conditions

Test Conditions are derived from Specifications.

White and Black Box Testing Techniques

Equivalence partitioning, Boundary Value Analysis, and State Transition are black box testing techniques.
Decision Table and Control flow are white box testing techniques.

Regression Testing

Regression testing should be performed after the software has changed, when the environment has changed, and to verify the Test Environment.

Monitoring Test Progress

Monitoring test progress includes tracking the percentage of Test Case Execution, percentage of work done in test environment preparation, and defect information.

Test Approach

The selection of a test approach should consider the context, including risk, skills and experience of the people, and the objective of the testing endeavor.

Large Systems

Testing large systems should be based on Risk.
