TestCafe Triggering Test By POST Request In Express - node.js

Question

I had a question that doesn't seem to be answered anywhere.
I am running tests from within my Express.js api. I set up a page that has a button and a field to enter a keyword intended to be used during a testcafe test. My endpoint I set up is /testcafe. But after sending a post request to /testcafe, there is a long delay while test runs and so my question is what is the best next step besides hanging?
Also, can my post request body, which contains the keyword, be directly used in a test like this? Keep in mind it's this pattern:
frontend -> POST request -> Express server -> /testcafe endpoint - test
My problem is after it reaches test, I currently have it attempting to call fetch from within the request logger. Is this right?
import { ClientFunction, Selector } from 'testcafe';
import { RequestLogger, RequestHook } from 'testcafe';
import zlib from 'zlib';
import fetch from 'isomorphic-unfetch';
const url = 'https://www.mysitetesturl.com/page';
class MyRequestHook extends RequestHook {
constructor (requestFilterRules, responseEventConfigureOpts) {
super(requestFilterRules, responseEventConfigureOpts);
}
onRequest (e) {
console.log('in onRequest!')
console.log('========================')
console.log('Request Body')
let buf = e._requestContext.reqBody
console.log(buf.toLocaleString())
}
onResponse (e) {
let buf = Buffer(e.body)
let unzippedBody = Buffer(zlib.gunzipSync(buf))
let payload = unzippedBody.toLocaleString()
fetch('http://myapiipaddress/api/testcafe',
method: 'PUT',
body: JSON.stringify(payload)
)
.then((err, doc) => {
if(err) {
console.log(err)
} else {
console.log(doc)
}
})
}
}
const myRequestHook = new MyRequestHook({
url: url,
method:'get'},
{
includeHeaders: true,
includeBody: true
}
);
fetch('http://myapiipaddress/api/testcafe',
method: 'GET'
)
.then((err, doc) => {
if(err) {
console.log(err)
} else {
fixture`myfixture`
.page(doc.url)
.requestHooks(myRequestHook);
test(`mytest`, async t => {
const inputField = Selector('input');
await t
await t
.wait(5000)
.typeText(inputField, doc.text)
.wait(5000)
}
);
}
})

According to your scheme, you need to organize your code in a different way:
const createTestCafe = require('testcafe');
....
// Choose the necessary body parser for express application
// https://github.com/expressjs/body-parser
app.use(bodyParser.urlencoded({ extended: true }));
...
app.post('/', function (req, res) {
createTestCafe('localhost', 1337, 1338, void 0, true)
.then(testcafe => {
const runner = testcafe.createRunner();
return runner
.src('/tests')
.browsers('chrome')
.run();
})
.then(failedCount => {
testcafe.close();
res.end();
});
})
