Answers for "what to do when bug in production"

why bug caught in production

Answer:
	Initially we need to check if the issue reported in
    Prod environment is a valid defect. If so:
	Than first of all I am trying to keep calm
    because whoever tested might be in a big trouble :)
    I reproduce the defect to check whether if error
    occur on my end aswell or is it because of 
    users error or configuration issue.
    If also gives an error on my end than I would
    go more into detail to check whether if it is
    only occur in specific browser or if I need
    different configuration etc.
    So while developers find the solution as a 
    tester I would try to find root cause of this
    issue. So before developers apply hotfix sometimes
    we need to also check since it is in production
    enviroment and if fixing the bug might lead other
    defects in the future. it could be even worse.
    So basically we need to brainstorming as a team
    to check how to apply hotfix.

what to do when bug in production

Answer:
	Initially we need to check if the issue reported in
    Prod environment is a valid defect. If so:
	1. The test environment is different 
        from Production environment.
    Exp: Access & Permissions in Prod environment,
    Memory limitations, Single & Multi-tenant
    configs etc is different.
	2. We dont test that scenario as a tester.
	3. There might be an issue regarding Timezone server time.
	4. One common reason for this behaviour is
    production data schema differs when we add new features 
    and if not updated or correctly replicated on all servers
    it might create production issues.
	5. Exhaustive testing is also not possible. ==> 
    We cannot test everything.
	6. Code is not migrated to Production environment properly,
    there might be some issues in migrating the code for that
    particular functionality where the issues caught.
	7. There might be requirement gap.
	8. Verify if Prod and QA had similar internet connectivity
    setup (like VPN, LAN, Wifi)
    
    Basically our team needs to apply hotfix.
