Summary
Fix custom failure messages in
NotElementsMatchandNotElementsMatchf.Changes
Expand
msgAndArgswhen forwarding toFailon both matching-list paths. Add full-output regression checks for empty and nonempty lists, with a formatted message and without a message.Motivation
assert.NotElementsMatchf(t, []int{1}, []int{1}, "case %d", 42)currently prints[case %d 42]instead ofcase 42. Calls without a custom message print a spuriousMessages: []line. The argument slice is passed as a single argument instead of being expanded. This fixes message rendering without changing the assertion result.Validation
go test ./assert -run '^TestNotElementsMatch' -count=1go test -race ./...go vet ./...go generate ./...produces no additional changes; Go and README formatting checks pass.AI assistance: implemented and tested with OpenAI Codex.
