Subject: add: test for PasswordHashChecker
X-Git-Url: https://code.wpia.club/?p=gigi.git;a=commitdiff_plain;h=cf2a4740366b2146e2de9492409785fcbf4d876b

add: test for PasswordHashChecker

The last of the four assertions is intended to record the fact that we
don’t currently check the hash of a “simplified” (here: lowercased)
version of the password. We might want to do this in the future, but in
my opinion that should then be a deliberate decision, which includes
updating the test accordingly.
