Repeat Nightwatch test automatically - selenium

Question

Does anyone know a way I can automatically rerun a Nightwatch test a set number of times?
I have the following code:
module.exports = {
'Log into system - create order': function (client) {
client
.url('XXXX')
.waitForElementVisible('body', 1000)
.assert.title('Reach - Log in')
.assert.visible('#UserName')
.setValue('#UserName', 'XXXX')
.assert.visible('#Password')
.setValue('#Password', 'XXXX')
.assert.visible('input[value="Login"]')
.click('input[value="Login"]')
.waitForElementVisible('img.test', 1000)
.assert.visible('li[title="XXXX"] a[tabindex="5"]')
.click('li[title="Sales"]')
.assert.cssClassPresent('li[title="XXXX"]', 'active')
.click('a[href="/Quotes/Add"]')
.waitForElementVisible('#s2id_CustomerId_Remote', 1000)
.click('#s2id_CustomerId_Remote')
.assert.visible('#s2id_autogen2_search')
.setValue('#s2id_autogen2_search', 'bik')
.waitForElementVisible('.select2-highlighted', 1000)
.click('.select2-highlighted')
.waitForElementVisible('#customerNotes', 1000)
.click('#s2id_ProductId_Remote')
.assert.visible('#s2id_autogen3_search')
.setValue('#s2id_autogen3_search', '123XP')
.pause(5000)
.assert.visible('.select2-highlighted')
.click('.select2-highlighted')
.pause(5000)
.assert.visible('.ui-sortable > tr')
.setValue('#Quote_PONumber', 'abc123')
.click('input[value="Create Order"]')
.waitForElementVisible('.ac-order-number', 1000)
.assert.visible('a[data-value="abc123"]')
.pause(5000)
.end()
}
}
rather than .end() the test I'd like to .rerun() the test say 30 times. I can't see an option to do this anywhere in the docs.
Many thanks in advance.

You can wrap your commands in a client.perform() and a for loop
client.perform(function(){
for (i = 0; i < 29; i++) {
client
.url('XXXX')
.
.
.
.end();
}
})

What you need is a little of async iteration logic and client.perform() function :
module.exports = {
'Log into system - create order': function (client) {
var currentIteration = 0,
iterationCount = 30;
function runTest() {
client
.url('XXXX')
// ... YOUR CODE HERE, WITHOUT .end()
.perform(function() {
if (++currentIteration < iterationCount) {
return runTest();
}
client.end(); // After passing 30 iterations end the session
});
}
runTest();
}
};

If you want to repeat he test with different inputs ? then you can do something like this
module.exports = {
"Login Fail Cases": function(browser) {
let dataSet = [
{ username: "madhus", pass: "madhus" },
{ username: "admin", pass: "admin" }
];
//will run for 2 times as length of dataset is 2
dataSet.forEach(function(data) {
browser
.url("https://localhost:3000/")
// you tests here
}, this);
// note: end the test outside the loop once all tests are executed
browser.end();
}
};
