When I do a go mod tidy. I got the following error:
go: github.com/stretchrcom/testify@v1.4.0: parsing go.mod: unexpected module path "github.com/stretchr/testify"
This error is due a package referring to testify before it was moved to github.com/stretchr/testify.
The solution is to add the following line in your go.mod:
replace github.com/stretchrcom/testify v1.4.0 => github.com/stretchr/testify v1.4.0
