Golang MockMania InfluxDB Client v2

09 Feb 2020 · One minute read · on Gianluca's blog

Recently I had to develop an integration with the InfluxDB Client v2 Golang SDK.

This SDK is useful to interact with InfluxDB v2, create organizations and users, write new points, and submit queries; it accepts the Golang http.Client.

influx, err := influxdb.New(myHTTPInfluxAddress, myToken, influxdb.WithHTTPClient(myHTTPClient))
if err != nil {

Having the ability to pass the HTTP client from the outside influxdb.WithHTTPClient(myHTTPClient) improves the familiarity golang developers have with the library; they know how to configure Transporters or how to inject logging, tracing, debugging. For what concerns Golang MockMania, it gives to use the possibility to pass the httptest client.

influxDBServer := httptest.NewServer(http.HandlerFunc(func(rw http.ResponseWriter, req *http.Request) {

influxClient, err := influxdb.New(myHTTPInfluxAddress, myToken, influxdb.WithHTTPClient(influxDBServer.Client()))

At this point you can write the response you expect from the influxdb server using the http.ResponseWriter.

Either way, even if you have to check what influxdb receives from the sdk or if you have to obtain a specific answer from InfluxDB to validate what your business logic will do, nothing will stop you from using checking the http.Request or utilizing the http.ResponseWriter to get what you expect.

Something weird with this website? Let me know.
