Basic knowledge of software testing

Test Basics

1, the purpose of software testing: proof (expression software can work) → Detection (found error) → Prevention (tube

Management quality)

2. Test Execution: Unit Test (UT execution): Test execution of a test case;

Integration testing (It execution): test execution of a set of test cases;

System Testing (ST Execution): Test execution at different test stages. What do these words mean, that they are not very targeted?

3, the purpose of regression testing: A. Verify that the error is fixed;

B. Detect if the changes to the code introduce a new error.

5, the main work of software testing: A. Examine the code, review the development documentation;

B. Conduct test design, writing test documents (Test plan, test scheme, test case, etc.);

C. Perform tests, identify software defects, submit defect reports, and verify that defects are eventually corrected;

d. Measure software quality by testing.

6, the emergence of software crisis mainly manifested in: a. Due to lack of large-scale software development experience and software development data accumulation, development work plan is difficult to develop;

B. Development of early needs analysis is not clear enough, resulting in late development contradictions concentrated exposure;

C. Do not follow the development specifications, development documentation is incomplete, the software is difficult to maintain;

D. Lack of rigorous and effective software quality testing means, the quality of the software paid to users is poor.

7. Consequences of the software crisis: A. Software quality is not high, it is difficult to stabilize;

B. The software project is postponed and the schedule is not controlled;

C. Increased costs and inability to control budgets.

8, the source of the software crisis: A. According to Moore's Law, hardware development is fast, corresponding to the expectation of software system

More and more high;

B. Increased complexity of software systems, requiring more than one person to cooperate;

C. Software development is a human intellectual activity, can not use the existing industrial engineering methods to organize management.

9. Various stages of the software life cycle: planning → requirements analysis → design → coding → testing → running → evaluation

10, Design: summary design (HLD): In the design phase of the various requirements into the corresponding architecture, each part is a functional clear module;

Detailed Design (LLD): Specific description of the work to be done for each module.

11, software development related elements: personnel, processes, tools.

12, software project team personnel composition: Analysts, designers, developers, testers, configuration managers, SQA (quality assurance personnel);

13, the Software development process type: Waterfall model, spiral model, RVPRUP process, IPD process.

14. Several important processes in software development: Demand management, configuration management, defect management, peer review.

15, the common reason for introducing defects: a. Lack of effective communication in the development process, or no communication;

B. The complexity of software is becoming more and more high;

C. Error in programming;

D. Changing requirements;

E. pressure on project progress;

F. Do not attach importance to development documentation;

G. Problems hidden by the software development tools themselves. Wait a minute......
