+@item @code{env} - test code which uses environment variables
+@item @code{fs} - create temporary files and compare a filesystem tree to an
+expected value
+@item @code{golden} - compare large multi-line strings against values frozen
+in golden files
+@item @code{icmd} - execute binaries and test the output
+@item @code{poll} - test asynchronous code by polling until a desired state is
+reached
+@item @code{skip} - skip a test and print the source code of the condition
+used to skip the test
