Unencumbered allows Cucumber to support step definitions written in D.
This is done by implementing the Cucumber
The best way to get a feel for how it's used is to look at the
calculator example. To run it,type
dub run in the
examples directory and
cucumber from the same directory in another shell.
Unencumbered works by using compile-time reflection to find all the
Cucumber step definitions written in D. That means that the server to be run
for testing needs to make a call to
all the modules to include in the search as compile-time string parameters.
Notice that the calculator example steps register
functions that vary in the number of arguments they can take, as well as
the type of those arguments. Some have to parameters, some take
parameters and one takes just one
The compile-time reflection generates code to convert any regular expression
capturing parentheses matches to the type(s) in the function declaration.
If the type is not convertible at run-time, an exception will be thrown. If a function with arity different from the number of capturing parentheses is registered, the code will not compile (try it and see!). If the regular expression is invalid (e.g. because a capturing parenthesis is never closed), a compile-time (CTFE) exception is thrown, so the code won't compile in that case either.
Step definitions are supposed to test the code and signal failure by
Throwable. The examples use the
unit-threaded, but regular
assert or anything else that throws on failure would work too.
Unencumbered actually reports the exception type and message
back to Cucumber over the wire protocol.
