# Verifies golang.org/issue/47738.

# In this test, the user has rewritten their imports to use rsc.io/quote/v3,
# but their go.mod still requires rsc.io/quote@v1.5.2, and they indirectly
# require rsc.io/quote@v1.5.1 but don't import anything from it.
go list -m -f '{{.Path}}@{{.Version}}{{if .Indirect}} indirect{{end}}' all
stdout '^rsc.io/quote@v1.5.2$'
! stdout 'rsc.io/quote/v3'
go list -e all
! stdout '^rsc.io/quote$'

# 'go mod tidy' should preserve the requirement on rsc.io/quote but mark it
# indirect. This prevents a downgrade to v1.5.1, which could introduce
# an ambiguity.
go mod tidy
go list -m -f '{{.Path}}@{{.Version}}{{if .Indirect}} indirect{{end}}' all
stdout '^rsc.io/quote@v1.5.2 indirect$'
stdout '^rsc.io/quote/v3@v3.0.0$'
