tests: add enhanced packet counter verification
Add support for inline packet counter verification to send_and_* functions. Diff dictionary is a dictionary of dictionaries of interesting stats: diff_dictionary = { "err" : { '/error/counter1' : 4, }, sw_if_index1 : { '/stat/segment/counter1' : 5, '/stat/segment/counter2' : 6, }, sw_if_index2 : { '/stat/segment/counter1' : 7, }, } It describes a per sw-if-index diffset, where each key is stat segment path and value is the expected change for that counter for sw-if-index. Special case string "err" is used for error counters. This then allows more precise packet counter verification by first defining a "zero" dictionary, e.g. for ED NAT: cls.no_diff = StatsDiff({ pg.sw_if_index: { '/nat44-ed/in2out/fastpath/tcp': 0, '/nat44-ed/in2out/fastpath/udp': 0, '/nat44-ed/in2out/fastpath/icmp': 0, '/nat44-ed/in2out/fastpath/drops': 0, '/nat44-ed/in2out/slowpath/tcp': 0, '/nat44-ed/in2out/slowpath/udp': 0, '/nat44-ed/in2out/slowpath/icmp': 0, '/nat44-ed/in2out/slowpath/drops': 0, '/nat44-ed/in2out/fastpath/tcp': 0, '/nat44-ed/in2out/fastpath/udp': 0, '/nat44-ed/in2out/fastpath/icmp': 0, '/nat44-ed/in2out/fastpath/drops': 0, '/nat44-ed/in2out/slowpath/tcp': 0, '/nat44-ed/in2out/slowpath/udp': 0, '/nat44-ed/in2out/slowpath/icmp': 0, '/nat44-ed/in2out/slowpath/drops': 0, } for pg in cls.pg_interfaces }) and then to specify only changed counters directly when calling one of send_and_* functions: self.send_and_assert_no_replies( self.pg0, pkts, msg="i2o pkts", stats_diff=self.no_diff | { "err": { '/err/nat44-ed-in2out-slowpath/out of ports': len(pkts), }, self.pg0.sw_if_index: { '/nat44-ed/in2out/slowpath/drops': len(pkts), }, } ) operator | is overloaded by StatsDiff class to perform a deep merge operation, so in above case, dictionaries for "err" and self.pg0.sw_if_index do not overwrite whole sub-dictionaries, rather the contents are merged, assuring that all the remaining counters are verified to be zero.
