When trying to run snaps.Matchsnapshot with packagestest returns error mkdir /redacted/..../go/packages/packagestest/__snapshots__: permission denied.

This is also happening when calling from "github.com/stretchr/testify/suite".

func (suite *ExampleTestSuite) TestExampleSnapshot() {
    snaps.MatchSnapshot(suite.T(), "hello world")
}

// In order for 'go test' to run this suite, we need to create
// a normal test function and pass our suite to suite.Run
func TestExampleTestSuite(t *testing.T) {
    suite.Run(t, new(ExampleTestSuite))
}
