- Use reflection to derive function name.
- Take test cases as variadic arguments, instead of requiring them to be wrapped
in a Table.
- Support naming test cases.
- Run test cases as subtests with t.Run.
Qualified imports of pkg/tt outnumber unqualified (27 to 24). Improve
consistency, and clarity, by changing the dot (unqualified) imports of
that package symbols to qualified.
cmp.Diff panics when comparing a struct that has unexported fields and no String
or Equal method, so change some structs to either export all their fields or
have an Equal method.
This fixes#1136.
The `AnyError` placeholder error can cause tests to succeed for errors
other than what was expected. That is, the use of `AnyError` can mask
bugs in a unit test. So replace it with the specific error, or error type,
the test expects to be raised.
This does not remove the anyError structure because it is used in
the TestCase.DoesNotCompile() method. To keep the size of this change
as small as possible I want to defer updating that use to a separate
change. However, remove the public AnyError var so future test writers
don't attempt to use it.
When the destination to scan into is an interface, its zero value is simply a
nil interface, losing the information of the original type and resulting in
error messages like "need nil, got $actual-type".
ScanToGo now handles this case specifically, and uses the string representation
of the interface type in the error message.
Before:
~> ns []
Exception: wrong type of argument 0: wrong type: need nil, got list
~> var x~ = x
Exception: wrong type: need nil, got string
After:
~> ns []
Exception: wrong type of argument 0: wrong type: need !!hashmap.Map, got list
~> var x~ = x
Exception: wrong type: need !!eval.Callable, got string
This is still not ideal, since the "need" type is not given as an Elvish "kind",
but it's much less confusing than than old "need nil" messages.
This fixes#715.
