Use-Cases for Testing

[GeorgeMac]

This issue documents scenarios / features we might want to have test cases around.

The goal will be to create 1 or more representative cases which we assert in the test suite.

From a high-level we want to ensure (or instead revise) we support the following features:

• All HTTP verbs
• Function cardinality (0, 1 and n arguments).
• Return cardinality (0 and 1 return arguments).
• Body argument mapping
• Query argument mapping
• Path argument mapping
• String coercion from path and queries to other types
• Pointer, Slice, Map and Object type support

We should compile a matrix of these capabilities and see what falls out of it.
