* test: Simplify data handling for transfer testsDavid Gibson2022-09-291-111/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | Many of our tests are based around performing transfers of sample data across passt/pasta created links. The data flow here can be a bit hard to follow since, e.g. we create a file transfer it to the guest, then transfer it back to the host across several different tests. This also means that the test cases aren't independent of each other. Because we don't have the original file available at both ends in some cases, we compare them by generating md5sums at each end and comparing them, which is a bit complicated. Make a number of changes to simplify this: 1. Pre-generate the sample data files as a test asset, rather than building them on the fly during the tests proper 2. Include the sample data files in the mbuto guest image 3. Because we have good copies of the original data available in all contexts, we can now simply use 'cmp' to check if the transfer has worked, avoiding md5sum complications. 4. Similarly we can always use the original copy of the sample data on the send side of each transfer, meaning that the tests become more independent of each other.

* test/passt_in_ns: Consistent sleep commands before starting socat clientStefano Brivio2022-09-221-4/+25
| | | | | | | | | | | | | | | There are some 'sleep 1' commands between starting the socat server and its corresponding client to avoid races due to the server not being ready as we start sending data. However, those don't cover all the cases where we might need them, and in some cases the sleep command actually ended up being before the server even starts. This fixes occasional failures in TCP and UDP simple transfer tests, that became apparent with the new command dispatch mechanism. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
* test: Use paths in __STATEDIR__ instead of 'temp' and 'tempdir' directivesDavid Gibson2022-09-131-4/+4
| | | | | | | | | | | | Instead of using the 'temp' and 'tempdir' DSL directives to create temporary files, use fixed paths relative to __STATEDIR__. This has two advantages: 1) The files are automatically cleaned up if the tests fail (and even if that doesn't work they're easier to clean up manuall) 2) When debugging tests it's easier to figure out which of the temporary files are relevant to whatever's going wrong Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* test: Group tests by mode then protocol, rather than the reverseDavid Gibson2022-09-131-0/+270
For example, passt/dhcp rather than dhcp/passt. This is more consistent with the two_guests and other test groups, and makes some other cleanups simpler. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
