How to pass arguments such as username and password in a test

Question

I use below code to initialize connection to avi controller,

func TestAvi(t *testing.T) {
    aviClient, err := clients.NewAviClient("<CONTROLLERNAME>", "<USERID>",
        session.SetPassword("<PASSWORD"),
        session.SetTenant("<TENANT>"),
        session.SetInsecure)
    if err != nil {
        t.Error(err)
    }

And then I run go test command to run the code. I would like to externalize CONTROLLERNAME, USERID, PASSWORD and TENANT. So that I can pass those as arguments to go test command.

Any assistance please?

so that I dont have to put the password in the code, I would like pass it in command line like `go test -password=12345` — Simon, Apr 25 '22 at 08:11
Oh. That's the opposite of externalizing :) You want to read it from externally (aka internalize). Environment variables are probably the way to go. — Jonathan Hall, Apr 25 '22 at 08:30

I don't recommend passing those via CLI args, they are often logged.

A simple and most widely used solution is to pass such information via environment variables, which you can read using the os.Getenv() function.

How you set the environment variables is entirely up to you and may vary from system to system.

For example:

func TestAvi(t *testing.T) {
    controller := os.Getenv("AVI_CONTROLLERNAME")
    password := os.Getenv("AVI_PASSWORD")
    tenant := os.Getenv("AVI_TENANT")
    userID := os.Getenv("AVI_USERID")
    
    aviClient, err := clients.NewAviClient(controller, userID,
        session.SetPassword(password),
        session.SetTenant(tenant),
        session.SetInsecure)

    // ...
}

I added `password := os.GetEnv("AVI_PASSWORD")` under function and added "os" under the import. Did AVI_PASSWORD="PASSWORD" in bash. When I do `go test` get error `undefined: os.GetEnv` — Simon, Apr 25 '22 at 08:37
@Simon I misspelled it, it's `os.Getenv()`. See edited answer. — icza, Apr 25 '22 at 08:38
