Software for video summarization of soft work __ Technical class

background

Soft work video has been watching for some time, just finished reading yesterday, I have a little summary and understanding, so write a small article to commemorate. Knowledge

The above is my learning to draw a mind map, the following specific introduction:SoftwareThe first chapter: the concept of software is mainly about
Software Features: Logical entity (abstract), the knowledge and technology into information, no mechanical wear phenomenon, development and operation received hardware restrictions, not completely rid of the manual development method, development costs more and more high
Software classification: Function, scale aspect, usage frequency consideration
Software crisis: Software development and maintenance of the serious problems encountered (not in line with the actual needs of users, development productivity can not meet user (hardware) requirements, poor product quality, the cost of development and progress estimates are inaccurate, poor maintainability, documentation is not perfect, the cost of rising)
Principles: Decomposition, independence, consistency, certainty
Software development model: Waterfall model, spiral model, round eighth chapter: Software Quality
Software quality: ① is the basis of measuring software quality
② implied demand is not explicitly presented to
③ defines some development guidelines to guide software personnel to develop software in an engineering way
Test principle: ① testing before the test to determine the software is wrong
② determine test results in advance
③ try to avoid testing programs that you write from yourself
④ should combine reasonable and unreasonable input
⑤ The software Requirements specification as the standard
⑥ to find the wrong letter is directly proportional to the old fault that has been found
The ⑦ test is relative and cannot exhaust all tests.
⑧ test cases are left for test reports and repeated tests, re-verify error correction procedures
Test methods: Static analysis technology, dynamic testing technology, white box method, black box methodSummary

This part of the study is not very in-depth, but also in the 1.1 points of the summary, slowly will be refined, digestion, absorption, more wonderful welcome to read the following steps.
