Error 404 Not Found while testing govmomi vapi/rest client using simulator

[pragyad3188]

I'm trying to create a govmomi/vapi rest client. The sample code is:

var insecure bool = true
type RestClient struct {
 url *url.URL
 restClient *rest.Client
}

func (c *RestClient) GetRestClient(ctx context.Context) (*rest.Client, error){
 soapClient := soap.NewClient(c.url, insecure)
 vim25Client, err := vim25.NewClient(ctx, soapClient)
 if err != nil {
  return nil, err
 }
 c.restClient = rest.NewClient(vim25Client)
 err = c.restClient.Login(ctx, c.url.User)
 if err != nil {
  return nil, err
 }
 return c.restClient, nil
}

The rest client is created successfully, I tested it by retrieving categories from vCenter using this client.
To write their unit tests, I'm using govmomi simulator and vapi/simulator.

import(
 "context"
 "testing"
 "net/url"
 "fmt"
 "github.com/vmware/govmomi/simulator"
 _ "github.com/vmware/govmomi/vapi/simulator"
)

func TestGetRestClient(t *testing.T){
 ctx := context.Background()
 model := simulator.ESX()
 defer model.Remove()
 err := model.Create()
 if err != nil {
  t.Fatal(err)
 }
 server := model.Service.NewServer()
 defer server.Close()
 url := server.URL
 var client RestClient = RestClient{url: url,}
 _, err := client.GetRestClient(ctx)
 if err != nil {
  t.Errorf("err = %v", err)
  return
 }
}

The testcase should pass, but it returns an error

err= POST "http://127.0.0.1:34691/rest/com/vmware/cis/session: 404 Not Found 

I'm not able to understand what I'm missing or doing wrong. I've done similar test for creating a govmomi client using simulator and it didn't give me such error.

Can you help me out with this? Thanks in advance!

Just glancing over, would be great to see the line where the error occurs. Feel free to take a look at this code/package how to properly construct a client incl. transparent reauth after session expiration: https://github.com/embano1/vsphere/tree/main/client

Btw: looks like auth issue on your end as I don‘t see user/pass being correctly set. Again, feel free to take a look at the above package and feel free to use it as it solves common use cases.

Thanks for such quick response.

1. The error occurs at line err = c.restClient.Login(ctx, c.url.User).
2. I'm not sure if this is an Auth issue because the restclient gets created successfully and I'm able to interact with vCenter to create new tags/retrieve the tags.[I create a RestClient variable and set its url field with my IP address, username and password and use this RestClient variable to call GetRestClient() function]
   The issue occurs while unit testing.

@embano1 Can you please take a look at it?

You're registering an ESX model, not vCenter: model := simulator.ESX().

Please follow the example I pasted above in the package or other examples and tests used in govmomi how to properly use and test the clients.
