It will give much more meaningful error messages and I think is easier to follow. > > expect_sz = sizeof(pkt_v6) - 20; /* Test shrink with 20 bytes */ > err = bpf_prog_test_run(prog_fd, 1, &pkt_v6, sizeof(pkt_v6), > buf, &size, &retval, &duration); > - CHECK(err || retval != XDP_TX || size != expect_sz, > - "ipv6", "err %d errno %d retval %d size %d expect-size %d\n", > - err, errno, retval, size, expect_sz); > + ASSERT_OK(err || retval != XDP_TX || size != expect_sz, "ipv6"); same as above, old CHECK printed all those values so it was ok-ish to combine checks. With ASSERT_XXX() let's do each error condition check separately. Same for all the rest below. > + > bpf_object__close(obj); > } > [...]
