+Configuration:

+Pipes enabled.
+Maximum number of barriers is set to 2.
+
+Coverage concepts:
+
+With number of barriers set to 2, and provided there is sufficient
+memory available, fifo_open -> pipe_new must be able to create a new
+pipe_control_t successfully.
+
+This test
+
+- Creates a directory /tmp
+- Creates a fifo file /tmp/fifo01
+
+- Opens the fifo in read-write mode, covering one of the cases of the
+  switch statement (this should be successful)
+- Closes the fifo
+
+- Opens the file in read-only, non-blocing mode, covering another case
+  of the switch (this should be successful)
+- Closes the fifo
+
+- Opens the file in write-only, non-blocking mode, covering yet
+  another case in the switch. (this should not be successful, instead,
+  since we opened the fifo in a WRONLY and NONBLOCK mode, we receive
+  an ENXIO error)
+
+- fifo_open (pipe_new) maintains a static character variable, which it
+  uses to create semaphores and barriers. The value of this character
+  goes from a -> z -> a -> z... To hit the case where z is wrapped
+  back to a, fifo_open must be called a minimum total of 26
+  times. This is achieved by repeated opens on the fifo file created.
+- After every successful open, the file is closed
+
+- Remove fifo file
+- Remove tmp directory
