Using ssh in cy.exe() always get timeout error - ssh

Question

I use ssh command in cypress exec command. ssh command works properly but I get timeout error from exec() function always.
My code is :
cy.exec('ssh username#111.111.1.1 "\file.exe"')
Actually this code works properly and I can see that file.exe works on remote desktop but I get error on exec().
I think I have to put some options inside the ssh command like -q -w . I tried some of them but it did not work.
Could you please help me?

Maybe exec is too limited in the way you can interact with the command being called, you need a programmable API rather than just configuration options.
You can try using a task instead, there is a library node-ssh that will interface with a Cypress task.
I'm not familiar with ssh protocols, so you will have to fill in those details, but here is a basic example for Cypress task and the node-ssh library
cypress/plugins/index.js
module.exports = (on, config) => {
on('task', {
ssh(params) {
const {username, host, remoteCommand} = params // destructure the argument
const {NodeSSH} = require('node-ssh')
const ssh = new NodeSSH()
ssh.connect({
host: host,
username: username,
privateKey: '/home/steel/.ssh/id_rsa' // maybe parameterize this also
})
.then(function() {
ssh.execCommand(remoteCommand, { cwd:'/var/www' })
.then(function(result) {
console.log('STDOUT: ' + result.stdout)
console.log('STDERR: ' + result.stderr)
})
})
return null
},
})
}
Returning result
The above ssh code is just from the example page of node-ssh. If you want to return the result value, I think this will do it.
module.exports = (on, config) => {
on('task', {
ssh(params) {
const {username, host, remoteCommand} = params // destructure the argument
// returning promise, which is awaited by Cypress
return new Promise((resolve, reject) => {
const {NodeSSH} = require('node-ssh')
const ssh = new NodeSSH()
ssh.connect({
host: host,
username: username,
privateKey: '/home/steel/.ssh/id_rsa'
})
.then(function() {
ssh.execCommand(remoteCommand, { cwd:'/var/www' })
.then(function(result) {
resolve(result) // resolve to command result
})
})
})
},
})
}
In the test
cy.task('ssh', {username: 'username', host: '111.111.1.1', command: '\file.exe'})
.then(result => {
...
})
Only a single parameter is allowed for a task, so pass in an object and destructure it inside the task as shown above.
