Introduction to Software engineering 10-testing

Error is the property of software, in order to grasp the correctness of the software development process, need to carry out a variety of validation and verification work. Verification and validation is a standardized evaluation method that runs through the software life cycle. Software validation proves that software products or intermediate products can meet customer requirements, including logical coordination, completeness and correctness, at all stages of the software life cycle. Software validation is a list of activities and processes designed to protect software products from their descriptive requirements. It includes confirmation of the requirements specification and confirmation of the procedure, while the procedure confirmation includes static confirmation and dynamic confirmation. Software testing fundamentals include the basic principles of software testing, the relationship between software testing and software development phases, test documentation, software testing information flow, and software testers.

The software testing strategy is as follows:

(1) Unit test: 1. Module interface Test 2. Local data structure Test 3. Critical execution Path Test 4. Error handling test 5. Boundary Condition Test 6. Unit test method.

(2) Integration test: 1. Top-down integration 2. Bottom-up integration.

(3) Confirm test

(4) System test: 1. Recovery test 2. Security Test 3. Strength Test 4. Performance test.

(5) Software debugging: 1. Simple test Method 2. Inductive test 3. Deduction Test 4. Backtracking test.

Software testing methods are: 1. Static and dynamic testing 2. Black box test method: (1) Equivalence class Division (2) Boundary value Analysis (3) state test (4) Failure condition test (5) Error Inference Method 3. White box test method: (1) logical Overlay (2) path test.

Object-oriented test types include model testing, class testing, interactive testing, system testing, acceptance testing, and release testing. The object-oriented test example has a date problem, a linear table problem, and a GUI test example. Current mainstream testing tools include functional testing tools, performance testing tools, defect management tools, and test management tools.
