+# Ick workers for my CI system
+
+Ick is my CI program. It needs workers on which it runs builds. These
+need to be accessible over ssh, and the remote user must have
+passwordless sudo access to run pbuilder.
+
+I have a number of the ick workers. Yarn does not provide a looping
+construct or parameterised scenarios. However, since they are all
+maintained using Ansible, and should thus be identical, I avoid having
+to repeat the scenario for each worker by just blindly assuming that
+if one works, they all work.
+
+    SCENARIO ick workers can build packages
+
+Basic checks.
+
+    GIVEN server name is ick-debian8-amd64
+    AND server has account ick
+    THEN server responds to ping
+    AND server hostname is as expected
+    AND server account has sudo
+    
+Do a test build of the Debian hello package.
+
+    GIVEN a remote temporary directory to use
+    AND a directory RESULT on the server
+    WHEN server runs apt-get source --download-only hello
+    WHEN server runs test -e *.dsc
+    WHEN server runs sudo pbuilder --build --buildresult RESULT
+    ... --basetgz /var/cache/pbuilder/release.tgz hello_2.9-2+deb8u1.dsc
+    THEN remote files RESULT/*.deb exist
+
+Cleanup.
+
+    FINALLY remove remote temporary directory
