Email Generation has way too many edge cases

[jlink]

Testing Problem

Email Generation has way too many edge cases which leads to only few generated email addresses to be
just normal and random

Suggested Solution

Restrict edge cases to just the most valid ones, e.g.

• a@a.aa
• "a"@a.aa
• " "@a.aa
• a@[1.1.1.1] or [0.0.0.0]?
• a@[FF::FF:FF:FF:FF:FFFF:FF]
• etc.

@zinki97 Any suggestions about edge cases for ip4 and ip6 addresses?

Any suggestions about edge cases for ip4 and ip6 addresses?

I think edge cases are 0.0.0.0, 255.255.255.255, 0:0:0:0:0:0:0:0 (or equal ones like 0:0:0::0:0:0:0) and FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF

I vote for ::1 (short form of localhost address) and :: (short form of all zeroes). Perhaps see some inspiration here: https://en.wikipedia.org/wiki/IPv6_address#Special_addresses

This is the current list of edge cases:

Obviously domain hosts and ip4 addresses are completely missing. More questions I have:

• Is ! really a valid local part?
• Is " " a valid quoted local part?
• Do [2:2:2:2:2:2:2:2] and [1:1:1:1:1:1:1:1] offer additional value?

Anything missing? Anything in that shouldn't be in?
