NewTestServer unreachable rpc address

[huahuayu]

Env

Mac m1 macos 12.4
Docker Desktop 4.10.1

Issue

When run abi/encoding_test.go/TestEncoding(t *testing.T) function

The testsuit/server.go NewTestServer() created a geth client, but port 8545 can't be reached.

func (t *TestServer) HTTPAddr() string {
	return fmt.Sprintf("http://%s:8545", t.resource.Container.NetworkSettings.IPAddress)
}

The docker container info

$ docker ps | grep ethereum

Inside the container the command is

I think it's because of the wrong geth command, it's actually equivalent to using blew docker-compose.yml to start a geth client, the container can get up, but inside the container, telnet 127.0.0.1 8545, doesn't work.

version: '2'
services:
  geth:
    image: ethereum/client-go:v1.10.15
    command: --dev --datadir /eth1data --ipcpath /eth1data/geth.ipc --http --http.addr 0.0.0.0 --http.api eth,net,web3,debug --ws --ws.addr 0.0.0.0 --verbosity 4
    ports:
      - "30303:30303"
      - "30303:30303/udp"
      - "8545:8545"

After some dig, I found there are two issues:

1. The geth version is hardcode 1.10.15 which may not support mac m1 chip good, but 1.10.25(the latest) is ok
2. The HTTPAddr() get the container's ip address but it can be accessed from the host

func (t *TestServer) HTTPAddr() string {
	return fmt.Sprintf("http://%s:8545", t.resource.Container.NetworkSettings.IPAddress)
}

I changed it to localhost with binding port then it's ok

func (t *TestServer) HTTPAddr() string {
	port := t.resource.GetPort("8545/tcp")
	return fmt.Sprintf("http://localhost:%s", port)
}

Now the tests can be run but some tests failed, FYI

This has been fixed in another way, instead of relying on a custom server for each test (which requires dealing with nuances from MacOs and Linux), there is a helper bash script that deploys the blockchain at startup. Now, the test cannot rely on an independent and isolated environment for the execution but it is easier to scale and remove these issues.
