What are the basic standards of software testing?

After passing the integration test, the software has been assembled and the interface errors have been eliminated. Confirm that the test can begin. The verification test should check whether the software can work according to the contract requirements, that is, whether it meets the verification standards in the software requirements specification.

1. Confirm the test standard

In order to realize software verification, a series of tests are needed. Validation testing also requires the development of test plans and processes. The test plan should specify the test contact and test progress, and the test process should define some special test cases to explain whether the software meets the requirements. Whether it is a plan or a process, we should focus on whether the software meets all the functions and performance stipulated in the contract, whether the documents are complete and accurate, and whether the man-machine interface (such as portability, compatibility, error recovery ability, maintainability, etc.) satisfies users. There are two possibilities to confirm the test results. One is that the function and performance indicators meet the requirements of the software requirements specification and are acceptable to users. The other is that the software does not meet the requirements of software requirements, which is unacceptable to users. At this stage of the project, it is difficult to correct serious errors and deviations within the predetermined time limit, so it is necessary to negotiate with users to find a proper solution to the problem.

2. Configuration review

Another important part of validation testing is configuration review. The purpose of the review is to ensure that the software configuration is complete, the classification is orderly, and the details required for software maintenance are included.

3.α, β test

In fact, it is impossible for software developers to fully foresee the actual use of programs by users. For example, the user may misunderstand the command, or provide some strange data combinations, or may be confused about the output information that the designer thinks is clear, and so on. Therefore, whether the software really meets the requirements of end users should be tested by users. The acceptance test can be informal test or planned system test. Sometimes, the acceptance test lasts for weeks or even months, and the errors are constantly exposed, which leads to the delay of development. A software product may have many users, and it is impossible for everyone to accept it. At this time, a process called alpha and beta testing is often used to find problems that only end users can find.

Alpha testing refers to the software development company organizing internal personnel to simulate various user lines to test the upcoming software products (called alpha version), trying to find errors and correct them. The key of alpha testing is to simulate the actual running environment and user operation of software products as truly as possible, and cover all possible user operation modes as much as possible. A software product that has been adjusted by alpha testing is called beta. Secondly, beta testing, that is, software development companies organize typical users in all aspects to actually use the beta version in their daily work, and ask users to report abnormal situations and make criticisms. Then the software development company will revise and improve the beta version.

What is a standardized test?

China is the hometown of exams. Even from the imperial examination system in Sui Dynasty, the examination has a history of 1300 years. Has a long history of examination and accumulated rich experience in examination.

Standardized examination is an examination method gradually developed in modern times. At present, it is still in the stage of exploration and experiment. With the continuous development of modern science and technology, mathematical methods and probability statistics methods have been applied to examination research, making examination a scientific means of educational measurement. In the past century, educational measurement has made great progress in some western developed countries such as the United States. Under the guidance of educational measurement theory, with the extensive use of modern means such as computers, a new standardized examination form appeared in the United States in the early 1940s.

Standardized examination is an examination organized according to systematic scientific procedures, with unified standards and strict control of errors. The examination needs to standardize the writing of test questions, the implementation of the examination, the marking and grading, and the conversion and interpretation of scores.

The implementation of standardized examination is a major reform of examination work in China, which will be recorded in the history of examination in China with a brand-new look. Compared with traditional exams, standardized exams have the following characteristics.

(1) test preparation

1) The organizational form of standardized test questions is open, scattered and regular. Each question is tested and counted, the quality of the question is scientifically evaluated, a question bank is established, and papers with different difficulties are composed at any time according to different examination requirements. For the same exam, ensure that the quality of each question is relatively stable. Compared with our traditional closed, centralized and surprise compiling, this form of compiling test questions has the advantages of convenient organization, economy and convenience, scientific and stable test questions.

2) The standardized examination has a large number of questions and a wide coverage, which can comprehensively examine the candidates' mastery of the teaching materials, at the same time, it can better prevent the disadvantages of guessing and betting questions, and guide students to pay attention to mastering the basic knowledge and theory of the teaching materials, which is really conducive to the selection of freshmen in universities and the teaching work in middle schools.

⑵ tissue measurement

1) The standardized test adopts the form of combining subjective questions with objective questions. If all multiple-choice questions are used, standardized tests also have their limitations. Candidates can't freely express their opinions, creativity and writing ability when answering questions, so they can't cultivate students' thinking of seeking differences and developing. Subjective questions can just make up for the weakness of multiple-choice questions, so the standardized examination currently adopted in China is a combination of subjective questions and objective questions. Practice has proved that these two types of questions can complement each other and complement each other.

Our current standardized test is to separate subjective questions from objective questions and print them separately. The objective questions and multiple-choice questions are volume one, which is answered by the unified answer sheet, and the subjective questions are volume two, and the candidates answer the questions directly on the test paper. In 2007, the English Department of the National Examination continued to test online marking, and the subjective test paper II candidates answered directly on the English answer sheet II.

2) The form of objective questions and multiple-choice questions consists of asking questions and answering options. At present, there are four options commonly used in China. Among the four options, only one option is correct, which is called multiple choice, and two or more of the four options are correct, which is called multiple choice. Candidates should pay special attention to the examination questions to avoid making unnecessary mistakes.

3) The answer sheets of the objective multiple-choice test paper (Volume I) are arranged in two ways. The order of the topics is different. Candidates aim at the question number when filling in.

(3) Review papers

1) The answer sheet for the first volume of the college entrance examination is marked with a cursor reader. Its characteristics: fast, accurate and labor-saving. Marking method: each answer sheet will be marked by one reviewer first, and then the score will be checked by another reviewer. Only when the results of two readers are consistent can we get the scores of candidates on the test paper. If the two results are inconsistent, the reader will automatically stop running and wait for the manual judgment result; In order to ensure the accuracy, during the marking period, the marking results should be randomly selected, and the randomly selected test papers should not be less than three thousandths of the total. In recent years, the annual college entrance examination papers are around 400,000. At the end of June every year, the candidates in the city openly search the papers, and * * * has consulted more than 3,000 subjects without any mistakes.

2) Subjective questions will still be marked by traditional manual methods, and we will take effective measures to strictly control the mistakes that are easy to occur in manual marking. Subjective questions of English will unified examination ......
