Protractor XHR plugin

We've encountered some issues with our e2e tests. We tried checking if clicks on specific links behave as they should (which also meant, send a POST XHR request to a tracking server).

Since we couldn't find any package for that, we wrote one.

So - this package waits for XHR to complete and enables a callback with its values for assertion.

Have fun!

Install

npm install protractor-xhr-plugin

or

yarn add protractor-xhr-plugin

Commands

waitForNextXHR

Calls the trigger, and then calls callback with the first xhr request corresponding to the given urlPattern, failing if timeout is exceeded.

Usage Examples

The function expects these parameters:

• urlPattern - a regex match for url pattern, will only listen to urls matching this, use '' for all urls.
• timeout - well, timeout

waitForNextXHR:

const {waitForNextXHR} = require('protractor-xhr-plugin');

it('should do things', (done) => {
   	waitForNextXHR('/some/path/regex/', 1000).then((xhrs) => {
		expect(xhrs.length > 0).toBe(true);
		done();
	});	
});

waitForNextXHR (async/await):

const {waitForNextXHR} = require('protractor-xhr-plugin');

it('should do things', async () => {
   	const xhrs = await waitForNextXHR('/some/path/regex/', 1000);
    expect(xhrs.length > 0).toBe(true);
});

The promise returns an array of objects containing the following properties :

• method (GET/POST)
• url (url of request)
• httpResponseCode (HTTP status response code, eg: "200")

When the anticipated XHR request has not occurred, it fails an assertion. Callback is not called and an error will be thrown

A huge thank you for the people at nightwatch-xhr for providing most of the code with their library. This one is just a fork adapted to Protractor.
