Let’s imagine this :
18h, Developer has delivered/shipped a tested version of software to production. 2 minutes later, the boss comes.
Boss : hi, the software (that you have shipped) is not working.
Developer (with a big ? on his head) : What ? That’s impossible ! It works in my PC and all tests are green.
Boss (turning around) : find the raison before 19h …
Developer : …
…
15 minutes later, all tests are still green in local PC. But prod is still red. Developer checks 3 times, the codes are exactly the same. What happens ?
30 minutes later, still at the start point. Developer becomes crazy. Which versions of server I have used ?
Local server version : 1.1.2 / Prod server version : 1.1.1
Does this cause the problem, checking about the release note, ah, yes, a new function added …
…
The problem solved.
