technical problem:
1. Among the items you have tested, which item do you think makes you feel the most meaningful, and why?
Come and pay. This project is the first APP project I tested. This project allowed me to quickly understand the business development status of the entire company. Through this project, I also better practiced the APP testing process and understood Some permissions of some APP third-party functions and the focus of testing.
2. Now open an interface, the interface shows 500, how will you judge and deal with this situation?
The 500 status code means a server error. First, check whether the currently required service is not up. If you are sure that the service is not up, you can check whether there is a problem with the configuration. If there is no problem, you need to cooperate with the development to find it. address specific issues;
3. If you encounter a problem that can be reproduced in the test environment, but cannot be reproduced in the development environment, how will you deal with this situation?
First connect with the development to see if the configuration method is the same as the method that the development told us. If there is no problem, describe the specific reproduction steps to the development. If the development still cannot reproduce, you may need to develop in your Assist in locating the cause on the computer;
4. If you encounter a problem that is not inevitable, and you have not found a way to reproduce it, how will you deal with it?
Firstly, record this problem on jira, describe the problem, phenomenon, frequency, impact on main business, etc. in detail, and then make a positioning with development assistance;
5. If there is a demand that will be launched on the same day, and all your preparatory work is done, you will wait for the development to launch the test, and then the development will launch the test on the morning of the launch day, but during the test, the process is completely blocked. It's a development problem, but it's going to go live that day, how will you deal with it?
First determine the time required for development and modification. If there is still no progress in the current progress for a long time, you need to report this situation to your leader in advance, explaining that the current demand may not be online on time, and explaining a current problem and its impact. Need postpone the launch;
6. Have you ever used packet capture? Have you used any packet capture tool?
If you usually test the web side, you can directly use F12 to locate the problem, and if you test the APP, you will use fiddler to capture packets
7. How do you check the error log?
Since the business I am currently testing has a main process, when an error occurs, after proficiency in the business, I can quickly locate the possible service exception, and then through the k8s command, I can find the relevant information in the service log. mistake;
8. Have you ever used jmeter or postman for stress testing?
I have used jmeter to run the interface, stress test a single interface, and use postman to debug an interface after mainly finding problems.
9. What are the steps for postman to perform interface testing?
- design test cases
- Configure the PostMan test environment
- Fill in the interface information in PostMan according to the test case (single execution, batch execution)
- Execute and analyze whether the result is consistent with the requirement document (add test assertion)
10. If I want to initiate a request, which three parts does this request consist of?
request header, request line, request body
11. When testing, there will be switching between multiple environments. How do you operate quickly? What are the operating steps when setting environment variables?
I will set up the test environment and the official environment. Postman is set in Enviroments. You can set global variables and environment variables, set the variables you need, click Save, and then switch the environment according to your needs when testing. Use { { } } reference variable
12. What are the differences between APP testing and WEB testing? How to conduct APP testing?
the difference:
The web side is a B/S architecture, based on a browser, and the APP is a C/S architecture, based on a client
The web test needs to be compatible with different browsers, and the APP side is compatible with different operating systems, system versions, mobile phone models, etc.
The web test update does not need to be downloaded, but the APP update needs to be downloaded
In addition to the basic function test, APP test also has APP special test, such as: installation and uninstallation test, interruption test, network test
How to test APP:
APP testing is mainly Android and IOS two mainstream operating systems. Functional testing is actually the same as web-side testing. Understand requirements, set use cases, and execute use cases. For APP, fiddler will be used to capture packets.
13. What programming language are you most familiar with? What kind of scripts have you written using it?
I will be a little familiar with python here. For the convenience of testing, I used python+selenium to write an automated script for creating products.
14. In python, what method is used to add new elements at the end of the list?
append
15. When you use python for interface testing, what are your commonly used functions? How do you operate when connecting to the server? By what means?
16. What are the commonly used Linux commands? What command is used to view the log
grep\ls\pwd\cat
tail -f info.log : Dynamically view the real-time output info.log log
tail -n 200 info.log: view the 200 lines after the info.log log
tail -f info.log | grep "orderId": Dynamically view logs containing the keyword orderId
17. Is the http protocol stateful or stateless? Do you know session and cookie? What's the difference?
HTTP is stateless, session exists on the server side, and cookie exists on the client side. The security of the two is not the same. Relatively speaking, session is more secure; the cookie storage size can only be 4K, and the number will also vary. There are restrictions, and the session has no data restrictions. However, when the service is accessed heavily, it may cause server resource constraints, so it is recommended to use cookies.
18. If there is a transfer function, how would you design these use cases? What methods will be used?
(Entrance of transfer, transfer process, change of amount after transfer, display of payee, change of payee amount) To design use cases from the perspectives of function, interface, security, etc., equivalence classes, boundary values, and scene method,
19. If there is a function of WeChat to publish Moments, how would you design test cases?
Publish entry, publish content (text, picture, video), friend permission (only visible to whom, invisible to whom, set permission group), publish address (mobile phone self-location, manually select location), publish
20. When testing interfaces, how would you design test cases? How do you think about the network level?
First of all, fill in the fields, required fields, non-required field combinations, default values, and the character type of the value, data size, data length and other dimensions to test;
21. If a new requirement comes in now, what is the testing process like?
Requirements Review, Test Plan, Write Use Cases, Use Case Review, Execute Tests, Log Bugs, Regression Tests, Test Reports
22. Now that you have found a bug, how would you locate the bug, and how would you deal with it?
Bugs in the development code can be located by looking at the logs. If they are functional or design flaws, you can go to the requirements document to see if your analysis is not in place. If not, you can directly contact the product manager for confirmation. , which is the most convenient and fastest.
I will compare my use case to confirm that it is a bug, then judge whether it is a front-end problem or a back-end problem, and submit it to ZenTao and assign it to the corresponding development. If my use case does not have this scenario, or they have modified it without notification For testing, I will confirm with the product whether there is a bug. If there is a problem with the product design, I will ask the product to consider a solution, or suggest a solution to him, and let him make a decision and notify the corresponding relevant personnel
23. Have you ever used a database? If there is a multi-table query now, how would you write this sql?
Use left joins, right joins, inner joins, cross joins, etc.
24. There is where in the database for conditional filtering, do you know the difference between where and having?
where can be used in select, update, delete, insert statements, and having can only be used in select;
When where and having are used at the same time, where is executed first, and after having is executed;
25. Have you ever used Linux, how familiar are you with Linux commands? If now I need to filter user A's real-time logs, how do you write this Linux command?
"tail -f log | grep 'A'", the k8s command I often use is, "kubectl logs -f srv-name --tail=30 | grep 'A'"
