[Feature]: make PRINT_LIMIT configurable
🚀 Feature Proposal
Make PRINT_LIMIT configurable via an environment variable similar to react-testing-library's DEBUG_PRINT_LIMIT. Also consider making it configurable via config file.
Motivation
See https://stackoverflow.com/questions/59763739/react-testing-library-some-portion-of-debugs-output-is-not-visible. By default RTL prints 100 lines of debug output but this is not enough to debug a large component. On the command line you can set DEBUG_PRINT_LIMIT=X to override it.
Similarly, for toHaveBeenCalledWith() and other matchers, when they fail it is sometimes not sufficient to see only 3 failed calls. This is a good default behavior, but sometimes it's handy to be able to print all the calls. In my use case I am testing a function that was called 7x. The 5th call is the one I want to validate. I am using .toHaveBeenCalledWith() and passing args. My expect is failing but it's unclear why. Because the debug output is limited to the first 3 calls I can't easily compare the expected vs actual args. Printing the full list of calls would be helpful.
Example
No response
Pitch
There is no way to configure PRINT_LIMIT currently without forking Jest. This is a small enhancement.
