Make attribute-write yaml tests play nicer with complex types. (#11457)
Browse files Browse the repository at this point in the history
The key change is using zapTypeToEncodableClusterObjectType to declare
the type and the "commandValue" partial to set it to the given value,
which is more similar to how we handle command arguments.  That makes
things work for lists and nullables at the very least.

The ignore="true" bit is probably not very well named, but it means
"just use the 'container' value as-is, instead of treating it as a
struct with member that stores the value".

The fix in ClusterTestGeneration.js is just fixing a typo in the
"type" values there that started to matter because we pass "type" to
zapTypeToEncodableClusterObjectType.

The fix in ClustersHelper.js is to give our synthetic "argument" to
writeAttribute the same nullability as the actual attribute, so the
types we get are right, and to set isArray for lists, because our
templates key off of that (especially the "commandValue" partial).
The "commandValue" partial also uses the "label" when dealing with
lists, so we define that for attributes to just be the attribute name.

The generated code changes are all no-ops so far, because we are not
actually using any types that would be affected by this yet.
