Answer 1

You either need to close(), or end your program.

However you can run into confusing issues if you don't close the file as

• sometimes test are run individually or a group of test are run in the same process. (So you could have a test which works one way but not the other)
• you cannot rename or delete an open file.

It is best practice to always close your resources which you are finished with them, however I see unit tests as scripts which don't always have to follow best practice.
