Where are the unit tests for Casdoor and how is it tested for production readiness?

@hsluoyz
I was looking at casdoor repository, but did not find any unit tests.
I am looking to use it in production, can you please point me to unit tests?
Just curious: How are casdoor featured tested thoroughly?
It'll be lot of work for me to add unit tests to be able to use open source casdoor.

it has cypress tests, but it does't have 100% coverage test cases. usually OSS won't assure you 100% no-bugs. you can also take a look at other products, even commercial ones like Okta if you need 100% no-issues
