Build fails when passing @autoclosure () -> Comment? = nil to #expect #485
Description
Description
The build fails when passing @autoclosure () -> Comment? to the #expect macro. Although the macro allows to pass it: https://github.com/apple/swift-testing/blob/3f73ced40e763ec193a4180726578ab430218abe/Sources/Testing/Expectations/Expectation%2BMacro.swift#L25
(Other macros are affected as well.)
Expected behavior
This builds successfully:
func testFunctionWithComment(
_ comment: @autoclosure () -> Comment?
) {
#expect(true, comment())
}Actual behavior
Building this returns an error:
Cannot convert value of type 'Comment?' to expected element type 'Array<Comment>.ArrayLiteralElement' (aka 'Comment')
Because the expanded version:
Testing.__checkValue(true, expression: .__fromSyntaxNode("true"), comments: [comment()], isRequired: false, sourceLocation: Testing.SourceLocation()).__expected()
Does not allow a optional Comment.
Steps to reproduce
Just try to build this:
import Testing
func testFunctionWithComment(
_ comment: @autoclosure () -> Comment? = nil
) {
#expect(true, comment())
}
