What is the difference between product function test and system test? This is often a place that confuses testers. Some partners think that system testing should include functional testing, and some believe that these are two separate test categories. In many respects, there is still a big difference between product functional testing and system testing. The editor of ZhuoMa Evaluation will briefly analyze the similarities and differences between the two, and how to do functional testing?
1. What does product function test and system test mean?
Product function testing refers to the verification of various functions of the software product or program, checking item by item according to the functional test cases to see whether each function can be used normally, and discovering potential software problems in the process. Usually functional testing does not consider the internal structure and code situation of the system, so it is also called black box testing.
System testing refers to the systematic testing of the product's hardware, software and application scenarios, simulating user scenarios for testing. The system testing phase generally occurs at the end of the software testing cycle, including functional testing, performance testing, and stress testing.
2. The difference between product function test and system test
1. Different test purposes;
Functional testing is to verify whether the system functions are available. System testing is to evaluate the overall system, usually biased towards the overall stability of the system;
2. Different test methods;
Functional testing is usually regarded as black box testing. System testing often uses boundary values and equivalence classes and other black box testing methods to analyze the test points.
3. The test environment and content are different;
Relatively speaking, the logic of the test content of the product function test is relatively simple, while the system test includes a variety of test types such as function test and performance test, which has higher requirements for the test environment and test. Therefore, many Internet companies also conduct system testing by third-party testing agencies, such as ZhuoMa Software Testing, which has a complete testing platform environment and professional testing team, and can provide standardized system testing services.
3. How to do functional testing?
Although functional testing is the basic type of testing in the software testing process, it also requires testers to be fully prepared for testing and to select appropriate testing methods to perform functional testing. There are several key points to do a good job in functional testing:
1. Do a good job in demand analysis
When doing requirements review work, you must fully understand the test content, what scope the functional test involves, and do a good job of statistical evaluation of the workload.
2. Develop a standardized test management process
Good process control in the project testing process can effectively improve testing efficiency, such as whether the project schedule will be affected when the requirements are changed, and through standardized tester management and schedule management, the project can be delivered on schedule.
The above are some video resources I collected, which helped me a lot in this process. If you don't want to experience the feeling that you can't find the information during self-study, no one answers your questions, and insists on giving up after a few days, you can join our deduction group [313782132], which has various software testing resources and technical discussions.
Of course, there are interviews. Interviews are generally divided into technical and hr interviews. In terms of format, there are few group faces. A small number of companies may have an intersection, but in general, the technical aspect is basically an inspection of your professional and technical level. , then hr surface mainly to see the person's overall quality and family situation character does not meet company requirements, in general, technology, then as long as through the technical hr surface is basically no problem (there are a few companies hr face will brush a lot of people)
we Mainly speaking on the technical side, the technical side is mainly to examine the professional technical knowledge and level. The above are also selected interview questions I have compiled.
Come on, test man! If you need to improve your plan, do it. It's better to be on the road than to wait and see at the beginning. There must be a law, and then there will be success.
If the resources are good, give a recommendation~
