In the first test code, there is a line:
@assert_equal Date.today.to_s(:db), actual.status_date.to_s(:db)@
I’m confusing about the symbol @:db@, what’s the meaning at here?
I try to remove it or rename it, the test still pass, it seems like useless at all, isn’t it?
There’s no related description about this symbol, can anyone enlighten me about this?
