2019-10-11tests: explicitly wait for the PG to finish before looking for capture fileAndrew Yourtchenko1-0/+15
Rather than only using time-based method of periodically checking whether the pcap file appeared, first check that the packet generator has stopped. To make this change fail-safe, have a 5-minute timeout on this activity, just in case the things go terribly wrong.

2019-07-31tests: disable pg capture before enabling itAndrew Yourtchenko1-1/+2
In a lot of places within the unit tests pg_start() starts the capture with an already existing capture running for the same test. If the pcap file already exists, then it is renamed and there is no problem. However, there is a potential for race if the previous pg_start() has enabled the capture, but the check for renaming it happened just slightly earlier than the first packet has arrived. Then a second call to pg_start() will hit a check that a file exists, and will cause an error. This is especially visible when running the tests in parallel due to increased load. Solution: disable the capture before enabling it. This will flush the aready running capture and eliminate the race. The additional delay that flushing of the pcap creates has exposed several other race conditions: NAT tests: Some of the NAT reassembly tests verify that the entries were added to the reassembly data structures, but do so by comparing the quantities of entries. With the default timeout being 2s, some of the entries might timeout, resulting in a bogus test failure. Solution: Bump the timeout to 20s for the affected tests. Punt tests: nr_packets == 3 makes test intermittently fail, nr_packets > 3 make it reliably fail, and nr_packets = 2 works Solution: set nr_packets == 2 for the time being IGMP tests: the leave-group calls get a spurious packet from the time the new groups were configured Solution: add 1 second delay before starting to delete the groups Type: test Change-Id: I931182a7b2860cf670e030ee7da8038f6e87356d Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

2019-06-27tests: rename stream name in testsPaul Vinciguerra1-1/+2
PacketGenerator streams were named based on their sw_if_index but without knowing that, it looked like it was paired with the interface instance value.

2017-02-09make test: work around scapy truncated packetsKlement Sekera1-0/+33
Under stress, it's possible to hit a race condition, when the packet header is fully written to pcap, but not all packet data - yet. Scapy is stupid enough to: 1. not detect and report this error, truncating the packet instead 2. continue munching more data from wrong offset The work around is to scan the file ahead, parse the packet header, figure out how much data we need, wait for the file to be big enough, then restore the file position back to where it was and finally let scapy parse the packet.

2016-12-23make test: improve handling of packet capturesKlement Sekera1-58/+128
Perform accounting of expected packets based on created packet infos. Use this accounting info to automatically expect (and verify) the correct number of packets to be captured. Automatically retry the read of the capture file if scapy raises an exception while doing so to handle rare cases when capture file is read while only partially written during busy wait. Don't fail assert_nothing_captured if only junk packets arrived. Change-Id: I16ec2e9410ef510d313ec16b7e13c57d0b2a63f5 Signed-off-by: Klement Sekera <ksekera@cisco.com>

2016-12-16make test: improve robustness and performanceKlement Sekera1-23/+59
Introduce an API which asserts empty capture for interface. Throw exception in old API if the capture does not exist, thus making it clear if the test expects packets to arrive or not. Improve performance by not doing sleeps after starting the packet generator, rather lazily deleting captures when needed. Fix wrong usage of packet.show() in various tests.
