What is the main purpose of software testing?

Test and discover software defects in the software.

Testing is the process of running through the software development lifecycle.

Defect report preparation and submission.

Software quality analysis.

In short, analyze the requirements, verify the completeness and accuracy of the function using rich test methods, and submit the test report.

1 Definitions. Software testing is to find out the differences and problems between the expected effect and the actual effect, and evaluate the software to measure whether it can meet the requirements and characteristics of the design.

2 Purpose. The purpose of software testing is to find problems, problems that have not been discovered until now. Check if the system meets the requirements.

3 Generalization. Software testing is about finding out the bugs in the software as early as possible before the developer puts it on the market! Because any software is theoretically problematic and not perfect!

The sooner you find the vulnerability, the lower the company's losses! That's why software testers are getting more and more attention!

Compared with the gender requirements of some industries, the current ratio of male and female employees in software testing is roughly 1:1

The main job content of a software tester is to conduct software testing according to the test plan and test plan; Able to develop test models, develop test plans, arrange test plans, and manage test projects according to software requirements.

The main work of software testing is verification and validation.

Verification is a series of activities that ensure that the software is performing some specific function correctly, that is, that the software does the event in the correct way.

Validation is a series of activities and processes designed to verify the logical correctness of software in a given external environment. That is, to ensure that the software does what you expect it to do.

Software testing is a process used to facilitate the verification of the correctness, integrity, security, and quality of software. The classic definition of software testing is the process of operating a program under specified conditions to find program errors, measure the quality of the software, and evaluate whether it meets the design requirements.

In simple terms, it is to test whether the software has just been done to have bugs Now the market continues to improve the quality of software, software testing will become more and more important, and the status and treatment of corresponding software testers will gradually improve. In large companies with standardized software processes, the number and treatment of software testers are not much different from those of programmers, and the salary of excellent testers is even higher than that of programmers, so software testing is a very promising industry

Of course, the work content of software testing engineers is mainly to test software and systems, so the specific testing work is divided into the following parts:

1. Demand review.

The first thing the team does after they get the requirements is to do a requirements analysis to see what the requirements are to be implemented by the software. The next step of requirements analysis is the requirements review, which requires the participation of software test engineers and product requirements personnel, developers, and QA personnel to review whether these requirements can be realized.

2. Write a test plan.

Next, while the developer writes the development plan, the tester writes the test plan, which is who will do what test work at what time, and what work results will be produced, that is, which documents will be submitted.

3. Write test cases.

A test case is a document that guides the testing work, such as the login function and purchase function of the system, and the test case is designed through the test method and strategy. Therefore, writing test cases is the most important job for software test engineers outside of testing.

Fourth, use case review.

A use case review is all about evaluating and reviewing whether the test method and test content are reasonable and comprehensive. It is not only necessary to do basic testing work, but also to comprehensively conduct tests that may cause a variety of errors to minimize bugs as much as possible.

5. Perform tests and submit bugs

Needless to say, the test engineer actually does the test work, finds the bug and submits it for the software developer to modify.

6. Regression testing and writing of test summary reports.

Regression testing is to re-test the software that the developer has fixed bugs to see if the bugs have been modified. After the bugs are modified, the tester should write a test summary report to explain the quality of the software before the software can be released online.

Software testingIt is to test the developed software functions and find out the software bugs, that is, to find out the defects and deficiencies of the software, and after finding out the problems, it is also necessary to organize them into a problem report.

Software (Chinese mainland and Hong Kong terminology, called software in Taiwan) is a collection of computer data and instructions organized in a specific order. Generally speaking, software is divided into system software, application software, and middleware in between.

Software does not simply include computer programs that can run on a computer (in this case, a computer in a broad sense).

The documentation associated with these computer programs is generally considered to be part of the software. To put it simply, software is a collection of programs and documents. It also refers to the management system, ideology and ideology in the social structure.

Ideological and political consciousness, laws and regulations.

The system software provides the most basic functions for the use of the computer, and can be divided into the operating system and the supporting software, of which the operating system is the most basic software.

System software is responsible for managing computer systems.

so that they can work in harmony. System software enables computer users and other software to treat the computer as a whole, regardless of how each piece of underlying hardware works.

White-box testing often requires direct contact with the source of the program, so a very important condition for white-box testers is to understand the corresponding development language, preferably more than half of the developers.

Black box testing does not require the ability to read the program source (of course, knowledge of software development is preferred), and the requirements of black box testers tend to focus more on the tester's understanding of software testing theory and the corresponding industry.

The main job responsibilities are to understand the functional requirements of the product, test it, check the software for bugs, decide whether the software has robustness, and write the corresponding test specifications and test cases. In short, a software testing engineer plays a "quality management" role in a software company, correcting errors in a timely manner and correcting them in a timely manner to ensure the normal operation of the product. I see that dark horse programmers have software testing disciplines, and I thought I would go to the actual audition recently to see the effect.

Software Test Engineer:

1. Formulate test plans according to software design requirements, design test data and test cases;

2. Effectively execute test cases and submit test reports;

3. Accurately locate and track problems, and promote timely and reasonable solutions to problems;

4. Complete the integration test and system test of the product, and the software function, performance and other functions of the product.

Software testing is the first choice for many novices to switch careers in the IT industry, so what exactly does software testing do? Today, let's follow Sichuan Excellent Employment to find out.

Software testing is the testing of software submitted by developers, simulating user use and finding problems. It is a series of process activities, including software testing requirements analysis, test plan design, test case design, execution testing, etc. It runs through the whole life process of the software testing project, and at each stage of the software project, testing activities with different purposes and contents should be carried out to ensure the correctness of each stage.

Software test engineers need to find program errors through white-box testing, black-box testing, equivalence class partitioning method, boundary value method, etc., and submit them to programmers for modification.

So the white box test is to find the bug by looking directly at the **, and the black box test is also the manual test, that is, to test whether there is a problem with the function without looking at the **. Gray box testing is somewhere in between. Unit testing, integration testing, and system testing are carried out through different units.

Regression testing is a secondary test, and acceptance testing is done through user feedback. The equivalence class division method, the boundary value method, the causal diagram method, the decision table method, the orthogonal arrangement method, the error estimation algorithm, and the scenario method are functional tests, while the load test and stress test are performance tests.

If you want to know more about the specific testing method, let's learn software testing at UEMP. The software testing course for excellent employment is still good. Its teachers are elites with many years of project experience, and they don't have to worry about development by learning from them.

In addition, the teaching methods adopted by Optimal Employment make your learning more efficient.

To sum it up in one sentence:

Software testingIt's to test whether the software works exactly the way we want it to.

In three words, it is: find bugs.

There are many ways to do this job testing:

According to the program execution status during the test process, it can be divided into static test and dynamic test.

Static testingRely only on analyzing or inspecting the source program.

statements, structures, procedures, etc. to check the program for errors.

Translated: the program does not run, look at the face ** There is something wrong.

Dynamic testingIt is by running the tested program, comparing the obtained running results with the expected results, and analyzing the operation efficiency and robustness.

Translated: two steps without illness?

According to the details of the specific implementation algorithm and the internal structure of the system, it is divided into black box test.

White box testing and gray box testing.

Black-box testingThat is, the program under test is treated as a black box that cannot be opened, and the tester checks whether the program functions can run accurately according to the specifications without considering the internal structure and characteristics.

To put it simply: this is a fill-in-the-blank question, only looking at the result, not the process.

White-box testingIn contrast to the black box test, it mainly uses the internal logic and relevant information of the program to check whether each path can work normally by detecting whether the internal actions are carried out in accordance with the settings of the design specifications.

The white-box test pays more attention to the internal performance of the program, and this question is scored based on the process.

Grey box testing, between black-box testing and white-box testing, not only the correctness of the output content, but also the internal performance. Of course, the gray box test is not as detailed and complete as the white box test, and only needs to judge the internal situation through symbolic phenomena or signs.

In addition to the above two classifications, there is also a division according to the way the program is executed: manual testing and automated testing.

I don't think I need to explain much. Manual testing is all about designing test cases.

Then, follow the test case step by step, and then compare the results, which is time-consuming and labor-intensive. Automated testing is much more convenient, running programs under pre-set conditions, analyzing results, and doing it all in one go.

Of course, a lot of software testing work is not yet automated testing, and even if you use automated testing, you can't completely abandon manual testing.

What is the job of software testing in a nutshell? In fact, bugs happen around us, for example, when we operate WeChat, WeChat flashbacks, for example, we go shopping, the product is 1 yuan, and it actually deducts you 99, itself is 99 and finally deducts 1 yuan, or you play a game, the game goes online and then goes offline, the equipment is lost, you can see, this is a bug. Software testing is to avoid these bugs, causing damage to users, and affecting users, which is what software testing does.

What does a software tester do?

Test and discover software defects in the software.

Testing needs to be done throughout the software lifecycle;

Test case report formation: In order to conduct better and more effective testing and ensure the quality of test work, testers need to design test cases and form test case reports before performing test work.

Test plan formulation: In order to better organize and implement the test work, the test leader needs to formulate a test plan, including test resources, test progress, test strategy, test methods, test tools, test risks, etc.

Bug report writing and submission: The tester writes a formal defect report for the defects found and submits them to the developer for confirmation and fixing.

Software quality analysis: After the test is completed, the tester needs to analyze the software quality based on the test results, including defect rate, defect distribution, defect repair trend, etc. Specific metrics are given for various quality characteristics of the software, including functionality, reliability, ease of use, security, time and resource characteristics.

Finally, a conclusion is given as to whether the software can be released or submitted for user use.
