Fundamentals of software Testing technology-notes (unfinished)

The purpose of software testing is to detect defects in software as much as possible, and software defects can be defined as omission of software implementation (omission of user requirement implementation), error (inconsistent with user's requirement), superfluous (additional implementation).

80% of errors are concentrated in 20% of the code----experience is justified ...

1. Test classification

Black box testing, not focusing on internal implementation logic, regards all implementations as a black box, focusing only on inputs and outputs, including:

Functional testing, performance testing, usability, reliability, security, serviceability.

White-Box testing, testing for the implementation logic within the program

Program plug-in, in the program inserted in the printing, asserted the content of testing requirements.

Domain test

Symbol testing

2. Test method

Black box

A. Functional testing

Equivalence class Partitioning

Boundary value

Error inference

Causality diagram

Decision table

Orthogonal analysis

B. Performance Testing

Indicators: throughput throughout, delay latency, packet loss, frame Lost rate, etc.

White box

A. Logical coverage

Statement overrides

Decision coverage

Conditional override

Decision-Conditional override

Path Overlay

B. Procedural structure analysis

Control flow, data flow, information flow
