What do you think of the testsuite at the moment ? I though about something, tell me if it looks a good idea to you.
I create a new test that will try to execute every not builtin scheme command.
The test parses the action directory to find the scheme commands.
For each command, it checks if an associated test file exists, lets say tests/fixtures/scheme/THECOMMAND.scm. If so it executes it. If not it just executes "(d-THECOMMAND)(d-quit)".
This would be a weak test in that case, but it could at least check that the command does not provoke a segfault.
Then the test could be a bit tougher. For example, we could decide that if a scheme command return FALSE, it makes the test fail.
