+# Smoke test vmdb2-built images
+
+This yarn file builds a basic image, and runs it under Qemu. The image
+is configured to have a serial console enabled, and the scenario below
+will log in as root (no password), and command the virtual machine to
+power off. If this works, the image is at least minimally functional,
+so the "smoke test" passes.
+
+More elaborate testing can be added, but smoke testing is enough for
+now.
+
+To run this yarn file, you need to run it as root (since it needs to
+build an image as root), and you need to run on a system where
+qemu-system-aarch64 is installed. Additionally, you need to add the
+following option to yarn:
+
+    EXAMPLE
+    --env ROOTFS_TARBALL=/path/to/rootfs/tarball
+
+This means vmdb2 will use the given tarball when creating an image,
+and if the tarball doesn't exist yet, it will create it. This makes
+testing multiple time much faster.
+
+    SCENARIO smoke test arm64 UEFI image
+    WHEN user runs vmdb smoke-uefi-arm64.vmdb --output smoke-uefi-arm64.img
+    THEN user can UEFI boot smoke-uefi-arm64.img and power it off from root shell
+
+    IMPLEMENTS WHEN user runs vmdb (\S+) --output (\S+)
+    "$SRCDIR/vmdb2" "$SRCDIR/$MATCH_1" \
+        --output "$DATADIR/$MATCH_2" \
+        --log "$DATADIR/vmdb.log" \
+        --verbose \
+        --rootfs-tarball "$ROOTFS_TARBALL"
+
+    IMPLEMENTS THEN user can UEFI boot (\S+) and power it off from root shell
+    cd "$DATADIR"
