See this topic, is not very familiar with, in the process of testing the interview, the interview often encounter such a problem, then we have to analyze how to analyze test?
Clear test articles
If you are interviewing them, the interviewer temporarily give you a cup, usually "disposable cups, plastic" These were already determined the test article. Well, if not given a clear test items, then how do you test it? In such relatively broad test, you need to gradually refine, refine step by step you want to test items, if you do not clear your test items, then you have no way to test. Therefore, I received a similar example:
- Test cup?
- Testing the ball?
- Test pen?
This is more broad definition of something, you should gradually refined, clear in the end is what you test items? If this step is not clear, then you can not carry out the test, these test things, and interested parties can gradually agreed. If it is face questions, then you need to pay attention, you can own assume a definitive test items for analysis, and then when the interviewer to ask questions, to brief your point of view.
So before the test is in progress, it must be clear what you want to test items, only know what, you can select the method and corresponding tools for testing.
Validation testing stage intervention
Different stages of testing methods and tools are different, you need to be clear intervention stage test article. Also to the cup, for example, I simply put it into the following stage, the stage may be the wrong points.
The concept stage
The concept stage, this stage is that this product is only a concept, there is no clear form, function-oriented user groups. So at this stage, how we want to test it? At this stage, we can only guide the team members to gradually refined the concept of decomposition , some abstract things were materialized. Then this entity of things, decomposition, to obtain the relevant parties needs identified, then these demands the decomposition into one point testable. For example: I want to produce a beautiful and practical cup.
- Pretty? The word abstract, what kind of cups considered beautiful, everyone's aesthetic is not the same, so that interested parties can illustrate, given some reference value, based on these reference values, go on to continue to refine the design of a model to access to relevant parties satisfied. Some prototype design, will be able to play such a thing, the user something abstract materialized.
- practical? The words and beautiful, like, too abstract. What kind of practical? These users also need to agree and clearly the main usage scenarios cup, the main user, what the main function is only clear that, your test scenarios and test points there.
- cup? Very cup type pair, such as glass, plastic cups, and the like steel cup. To determine the material of the cup used, because different materials, and different food safety requirements and targets, so this step is more critical.
After the abstract things materialized, then it can be substantiated by the decomposition of these things, access to relevant test points. At last, for example, if we choose the material is glass, it would need to understand the policies and systems of food safety, understand the current glass which comply with these policies? There's policy is to test the system input, you can extract the relevant test points, to get some data through a number of test tools, and policies of the last indicators are compared to determine whether the material meets the requirements.
So in the concept stage, the focus is on something what is the use of what material manufacturing, which belongs to the core of things, once the positioning error, then all subsequent work was in vain. This gives stage, there are things we can test aspects of the model diagram, the state policy indicators, related documents and other static walk-through to determine document does not have typos, or descriptive errors.
The design and implementation phase
At this stage, there will be some clear design document, a clearer definition of the product's features, appearance, user groups, and other usage scenarios. Based on these testers text information, proposed that the corresponding test point, the process will involve testing some common analytical methods, such as "equivalence classes, boundary value, the determination table, FIG cause" and so on.
At this stage, it is necessary according to the relevant product documentation, test point extraction, preparation of test ideas, review test ideas, writing test cases, test execution, defect tracking, test reports. It should be the product of a variety of tests to ensure products meet customer needs, to meet the quality indicators meet the quality policy indicators, to meet some safety indicators.
At this stage, more concentrated test, test and diverse types. Test types are as follows: unit testing, integration testing, system testing, the UAT test, the interface display, functional, exploratory testing, security testing, compatibility testing. Each test type, interface is different.
As the various types of test input Test, tools and techniques used in the test output test, no curing method, because the test products are unique, but the test method may draw the analogy. For this type of testing is not to explain, you can check online.
Market
Product testing is complete, after the adoption of user acceptance, after the end of the project. Products enter the market, can be seen in the market for, and purchase. At this stage, we can see a complete product, packaging will be with the relevant certificates, Product description, quality certification and so on.
At this stage, the test is over, users find product defects, are some of the external costs that may affect the reputation of the product, experience, income, etc., affect the cost and repair of these defects are relatively large. For some serious flaws, then you need to repair, after the repair is completed, should be tested to ensure that changes the defect does not affect the original function, but also to ensure that the defect is modified, to meet user expectations.
At this stage, the basic end of the test, in addition to problems with the product, needs after the maintenance, testers check out.
Cup test
In a clear test items, test access stage, it can be targeted for cup test by obtaining test data and expected results compare to determine the test is passed or failed.
During the interview, in fact, you see the cup, is through the quality assurance of products, which is already on the market. At this stage, we focus is on quality certification, quality manual, cups have not used, there is no crack, some of these things like appearance and specification. But if you want to say, that is not the result of the interviewer wants to hear.
The interviewer wants to hear is the design and implementation phase, how do you test for the cup? With glass, for example described here under:
-
Visual inspection (testing interface)
Pretty clear appearance in line with user requirements.
-
function test
Clear glass features to meet user functional requirements.
- What material can hold.
- How much material can hold.
- Specific function requested by the user, such as insulation, drop resistance, high temperature, insulation and the like.
-
Usability testing
This cup really easy to use. These cups can be distributed to users not used, investigate their usage to understand this cup ease of use.
-
Portability test
Here is the cup for whether portable. For software, you can see the software migration from one environment to another set of environment, the system can be used normally.
-
Compatibility Test
Cups in different environments, can be used normally. This cup as in Africa and Asia, using the method are the same, without any deviation. For software, the software in different browsers, different operating systems, different mobile devices, the same functionality interface display, use function should be consistent.
-
Drop resistance test
Cup falling from different heights, the height of the glass breaking test. And at this height, it fell several times before completely broken.
-
Safety test
Testing to determine the safety indicators, such as after broken glass, glass sharpness, may scratch people.
Here are these types, there are other types, is not given here to enumerate.
to sum up
When contacting a clear themselves, are not familiar with the article, with reference to the above can do.
First you have to understand what this product is, for example, ask the following five questions:
- Its main function
- It is mainly used scene
- With which technology to use it
- What impact will bring its produce
You only understand this product, you have a more detailed break it to cut into the surface. To an unfamiliar product to break down, and then use the analogy, to own property and associated items, unknown to break through barriers.
Secondly, they want to know what you do. After only confirm the good demand, determine what to do good, they can against drugging, find their focus, focus assault.
Finally, complete the identification of needs, after knowing what they do, you need to choose the right methods, tools to aid in the completion of the required work. As the saying goes "工欲善其事必先利其器."
