How to specify a username in a host file

Question

I am using the host file as shown below

[qa-workstations]
10.39.19.190 ansible_user=test ansible_ssh_pass=test

I use the command below to execute the whoami command in the host

root@Svr:~/ansible# ansible all -a "whoami" -i /etc/ansible/host
10.39.19.190 | success | rc=0 >>
root

by default, it tries to use the username in which I logged in, i.e. root instead of the test user that I specified in the host file

It works fine when I try to pass the username in the unsible cli command

root@Svr:~/ansible# ansible all -a "whoami" -i /etc/ansible/host -u test
10.39.19.190 | success | rc=0 >>
test

But I will not be able to pass the username every time in the CLI, because the other host uses a different username. Also I do not have a key pair generated for each host, because the host machine often changes

Used version

:

 ansible 1.5.4 
 Ubuntu 14.04 LTS
