Setup in command test fails to create dir or touch file

I tried setup to create an file which is required to be present or mapped from outside while running the docker image. I tired touch and mkdir but the file is not created. Can you please help me.
```
- name: "cli command with Config map"
setup: [[ "mkdir", "/data/vishal" ]]
command: "ls"
args: ["-a"]
expectedError: [""]
expectedOutput: ["vishal"]

```

```
