What are the principles and strategies of software testing?

Basic principles of software testing All testing standards are based on user needs. The purpose of testing is to find out whether the system meets the specified needs.Early and continuous testing. The earlier the test is carried out, the lower the cost of repairing defects will be.

A successful test is a test that finds errors that have not been found so far. Principle of software testing: "Continuous software testing as early as possible" should be taken as the motto of software developers. The test case should consist of two parts: the test data and the corresponding expected output results.

Programmers should avoid checking their own programs. Try to avoid the randomness of the test. Each test result should be comprehensively checked. Keep the test documents, including test plans, use cases, error statistics and final analysis reports.

The main principles of software testing: software developers, that is, programmers, should avoid testing their own programs. Test model---w model. Both programmers and development teams should avoid testing their own programs or functional modules developed by the group.

The test should be carried out as soon as possible, and it is best to start to intervene at the demand stage, because the most serious mistake is that the system cannot meet the needs of users. Programmers should avoid checking their own programs, and software testing should be the responsibility of third parties.

How to write a test strategy

1. Write down the test methods to be applied in this project test.Clearly list which types of tests you will use as test guides. For example: functional test, user interaction interface test, integration test, stress test, security test, etc.

2. The comprehensive strategy of the test is as follows: comprehensive analysis and careful division. First, carry out equivalent class division, including the equivalent division of input conditions and output conditions, and turn infinite tests into finite tests to reduce workload and improve test efficiency.

3. Then the test plan should be written in more detail; if they are all senior personnel, the execution body of the test plan can be written more broadly.

How many stages are there for software testing? What are the test strategies and requirements of each stage?

1. Software testing is generally divided into 4 stages: unit testing, integration testing, system testing and acceptance testing. Software testing runs through the entire software life cycle. The objects of software testing include software requirements, outline design, detailed design, software running environment, executable programs and software source code, etc.

2. Requirements analysis: Before the test begins, the test team needs to carefully analyze the requirements documents of the software to ensure a full understanding of the functions, performance, security and other related requirements of the software.

3. The testing stage is generally divided into five stages, namely the requirements analysis stage, the software design and coding stage, and the integration stage. System stage and acceptance test stage. Software Testing describes a process used to promote the correctness, integrity, security and quality of software.

4. The whole test stage is divided into three stages: unit test, assembly test and system test. The test methods mainly include white box test and black box test. The above are the five stages of the software development process, but sometimes it is not necessary to follow this process in the software development process.

5. The software testing life cycle includes 6 stages (generally): 1) plan 2) analysis, 3) design, 4) construction, 5) test cycle, 6) final test and implementation, and 7) after implementation.

6. Test plan stage: the main task is to prepare a test plan, refer to the software requirements specifications, and the overall project plan, including the test scope (from the requirements document), schedule, the allocation of manpower and material resources, and the formulation of the overall test strategy.Risk assessment and avoidance measures have a formulation.

... First of all, we need to transform the system requirements into test requirements. What does the test strategy refer to? Test strategy and test cases...

Functional test, performance test, stress test, capacity test, security test, GUI test, usability test, installation test, configuration test, abnormal test, backup test Trial, robustness test, document test, online help test, network test, stability test.

Adopt the review and update mechanism to ensure that the test plan meets the actual needs; create the test plan and test detailed specifications and test cases respectively.

What is demand analysis? My understanding of demand analysis is to figure out what functions users need and how users will use the system. In this way, when we test, we can know more clearly how the system should run, so that we can better design test cases and test better.

List the recommended test requirements (advanced requirements). Recommend available test strategies and explain these strategies. Determine the required resources and estimate the workload of the test.

The more detailed and accurate the test requirements are, the deeper the understanding of the tested software, the clearer the content of the task to be carried out, and the more confident it is to ensure the quality and progress of the test.
