This is the penultimate question from Tencent’s 2015 school recruitment test engineer written test. After reading the reference answers and everyone's comments, I have a lot of reflection and new understanding of the term "divergent thinking". Excerpts are now taken to deepen the impression.
Take the copy and paste function of windows as an example, write as many test ideas as possible.
1. Basic function test
The file copy and paste function, first of all, the keyword "file", the files have different categories (pictures, videos, audios, documents, etc.), and each category has a different type (document type: txt doc execl pdf, etc.), each The files have different sizes, and the files have many permissions, are they hidden, or are they executable only by the administrator. Choose different types of different categories and files of different sizes as test resources.
For example, txt files in the document type can be divided into 1.KB txt files, 1MB txt files, and 1GB txt files. . . . There are many ways to copy and paste the next keyword, right-click to select, Ctrl+C, drag and copy, and there are also various ways to paste. Then copy from and paste to, for example, there can be local hard disk, mobile hard disk, USB flash drive, memory card, floppy disk, CD-ROM, connected mobile phone storage, copy to network address and so on. Is the file available after copying and pasting? Is there any change in file permissions? How to deal with the insufficient capacity for copying in the past? How to deal with the file with the same name after copying? How to deal with canceling, shutting down, or unplugging the USB flash drive during the copy process? Can the file be executed during the copy process?
2. Performance test
How about the performance of the copy and paste function? Is the speed of copying files acceptable? Is it possible to copy multiple files at the same time? Does it take up much CPU resources and power consumption during the process of copying files?
3. Compatibility test
Does Windows XP, Windows 7, Windows 8, Windows 8.1, Windows 10 and other Windows versions support this function?
4. Interactive test;
When copying and pasting files, is there any impact on using other functions of windows storage? For example, playing local audio, video, etc. and copying files at the same time is not an impact. Does it matter if you copy and paste at the same time?
Supplement
the content and size of the copy: text, including the number, size, color, thickness of the text, there are dozens of text settings in the word, of course it is very troublesome to test, in order to reduce the test cases, you can use the combined test, yes Copy a variety of different text; pictures, including picture resolution, color, picture size, location, etc.; file: size, type, location, whether compressed, etc.
Stability of paste
Will the size change after pasting? Will the content format change? Can’t paste it? Will the copied content be found after a mistake?
Security of pasting
After the pasted content is pasted, will there be leakage elsewhere, etc.
2. Performance test
- (1) Time: the response time of copy and paste? The display time of the page?
- (2) Load: Is there any abnormality in repeatedly copying and pasting? Is it acceptable to copy and paste one or more files with a large capacity?
-(3) Strength: Under the condition of ensuring sufficient capacity, copy and paste files of 50GB, 100GB, 500GB, ... respectively, and see when the failure occurs, and the performance after the failure, can you copy and paste 50G normally again? - (4) Capacity: Under different CPU resource conditions, what is the maximum capacity of files that can be copied and pasted for 5 minutes?
5. Interface test
Is the display interface of the progress bar consistent with the design style of the system when copying and pasting? Are there any textual errors in the display interface? Is the cloth of the display interface reasonable? Are the buttons on the interface available (for example: can I choose to abort? Is it available to minimize?)
6. Localization test
The display is normal in different language environments
7. Auxiliary testing
Can it be displayed normally under high contrast?
