+Check the locations of error messages when something is wrong in the body
+of a device's connect function:
+
+  $ ./test.exe configure -f errors/in_device.ml
+  test.exe: [WARNING] Skipping version check, since our_version ("1.0~test") fails to parse: only digits and . allowed in version
+  $ dune build
+  File "errors/in_device.ml", line 6, characters 2-26:
+  Error: Unbound value Unikernel_make__4.start'
+  Hint: Did you mean start?
+  [1]
+  $ ./test.exe clean -f errors/in_device.ml
+
+Check what happens when the number of the arguments passed to the functor is
+not the right ones. First, too many parameters:
+
+  $ ./test.exe configure -f errors/in_functor_too_many.ml
+  test.exe: [WARNING] Skipping version check, since our_version ("1.0~test") fails to parse: only digits and . allowed in version
+  $ dune build 2>&1 | head -n1 | cut -d',' -f'-2'
+  File "errors/test/main.ml", line 10
+  $ ./test.exe clean -f errors/in_functor_too_many.ml
+
+Then, not enough:
+
+  $ ./test.exe configure -f errors/in_functor_not_enough.ml
+  test.exe: [WARNING] Skipping version check, since our_version ("1.0~test") fails to parse: only digits and . allowed in version
+  $ dune build
+  File "errors/test/main.ml", line 34, characters 3-26:
+  Error: The module Unikernel_make__4 is a functor, it cannot have any components
+  [1]
+  $ ./test.exe clean -f errors/in_functor_not_enough.ml
+
+Also check that we have proper errors when the config file is missing:
+
+Configure failure
+  $ ./test.exe configure --vote=dog
+  configuration file config.ml missing
+  [1]
+
+Query failure
+  $ ./test.exe query --vote=dog
+  configuration file config.ml missing
+  [1]
+
+Describe failure
+  $ ./test.exe describe --vote=dog
+  configuration file config.ml missing
+  [1]
+
+Clean does not fail
+  $ ./test.exe clean --vote=dog
+
+Help does not fail
+  $ ./test.exe help --man-format=plain > /dev/null
