Go: build error when compiling unit tests (I'm trying to mock influxdb types)

问题

I'm just starting with go language. My mini-project successfully reads data from InfluxDB. Problem: when I import my package (which uses InfluxDB) into my unit test package, the build fails.

"Production" code:

package data

import client "github.com/influxdata/influxdb1-client/v2"

func FunctionToTest() {}

// To make import necessary, unused for now
func createClient() (client.Client, error) {
    return client.NewHTTPClient(client.HTTPConfig{Addr: addr})
}

Unit test:

package data_test

import (
    "../data"
    "testing"
)

func TestSandBox(t *testing.T) {
    data.FunctionToTest()
}

I expected this to compile/run but:

Thanks for any help or suggestion.
