Description

As a reminder, this project is being built upon the following starter project on Repl.it, or cloned from GitHub. In the next challenges we are going to simulate the human interaction with a page using a device called 'Headless Browser'. A headless browser is a web browser without a graphical user interface. This kind of tool is particularly useful for testing web pages, as it is able to render and understand HTML, CSS, and JavaScript the same way a browser would.

Instructions

For these challenges we are using Zombie.JS. It's a lightweight browser which is totally based on JS, without relying on additional binaries to be installed. This feature makes it usable in an environment such as Repl.it. There are many other (more powerful) options.
Look at the examples in the code for the exercise directions Follow the assertions order, We rely on it.

Tests

tests:
  - text: All tests should pass.
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=4').then(data => { assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: You should assert that the headless browser request succeeded.
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=4').then(data => { assert.equal(data.assertions[0].method, 'browser.success'); }, xhr => { throw new Error(xhr.responseText); })
  - text: You should assert that the text inside the element 'span#name' is 'Cristoforo'.
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=4').then(data => { assert.equal(data.assertions[1].method, 'browser.text'); assert.match(data.assertions[1].args[0], /('|")span#name\1/); assert.match(data.assertions[1].args[1], /('|")Cristoforo\1/);}, xhr => { throw new Error(xhr.responseText); })
  - text: You should assert that the text inside the element 'span#surname' is 'Colombo'.
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=4').then(data => { assert.equal(data.assertions[2].method, 'browser.text'); assert.match(data.assertions[2].args[0], /('|")span#surname\1/); assert.match(data.assertions[2].args[1], /('|")Colombo\1/);}, xhr => { throw new Error(xhr.responseText); })
  - text: You should assert that the element 'span#dates' exist and its count is 1.
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=functional&n=4').then(data => { assert.equal(data.assertions[3].method, 'browser.element'); assert.match(data.assertions[3].args[0], /('|")span#dates\1/); assert.equal(data.assertions[3].args[1], 1);}, xhr => { throw new Error(xhr.responseText); })
