Unit testing - some issues related to code organization in c++ testing
I am a novice c programmer. I used JavaScript most of the time. Now due to homework needs, I am writing a project in c. The development environment is Xcode. I want to do the tests myself, but I have no knowledge about testing before. As far as I know, after reading this, I decided to use the catch testing framework.
When I was writing a small C job before, I either cout<< directly in the main function and then deleted it before submitting, or I created a new cpp file, added the main function, and then added the main function in the project Temporarily change the name (usually I change the main function name to main00 or the like), click Run in XCode to temporarily test it, mainly to test the uncertainty in a certain place, and then change it back after the test is completed.
But I think the methods listed above are really stupid and make all seniors laugh.
Now my project directory is like this (this is a job to implement minisql in c): 
Currently, each file actually has no content. Each folder represents a module. The relationship between each module is as follows:
I plan to write one part and test one part (for example, write BufferManager first). If there is no problem in the test, continue to write the next part.
So now I have the following questions about the organization of test files:
Should I put the test files in the corresponding module file directory? Or is there a separate test file?
Should each module have a separate test file?
In addition, I found that if I write two test files, even if I comment out #define CATCH_CONFIG_MAIN, this still cannot run normally unless all other test files are commented out.
In addition, after I write the entry file (there is a main function in NewSQL.cpp), how should I run these test files? Are you still commenting and uncommenting....
I feel like the question I asked is a bit too stupid, but I really want to know how to write and use the correct test. I couldn’t find a very targeted answer on the Internet, so I came here to ask, thank you~
(If you think something is not done well, please point it out and I will seriously correct it, but please do not attack personally. If your answer is very valuable for reference, I will also send you a private message to ask if you need a certain amount of red envelope remuneration. Student Party, let’s express our feelings)
