test_import_time takes a lot of time

[alwx]

Rasa version: 2.3.1 (used main branch, commit hash: 2574c46e9576607a7b8de39f823ff3e5c01a475c)

Rasa SDK version (if used & relevant): 2.3.1

Rasa X version (if used & relevant):

Python version: 3.7 / 3.8

Operating system (windows, osx, ...): MacOS / Windows

Issue:
tests/import_time.py::test_import_time takes about 1.5-2 minutes on my machine (slower on Windows), and it's one of the most time-consuming tests we have. Partially it's because we run this measurement 15 times and get an average time it takes to import Rasa after 15 attempts.
I doubt it's needed. First of all, we might consider limiting the number of measurements. But even if we don't want to, we need to think of how we actually use this number.

See more details about time measurements: https://docs.google.com/spreadsheets/d/1tDRD0vWaLW91W1wPj5h__dwXuXioRt9aBPYyF1n4MjI/edit#gid=57091041

Definition of done:

• Set up a separate job
• Check if it's required
• Fix it

Importing rasa is very slow, it would be great if the import speed is fixed instead. Even my project's tests are slow because it imports Rasa at the start of each run.

@Mazyod Thanks for your input. Import time was recently fixed on main. Will be released with 2.5.0
