Swift and XCUI tests for beginners

I went to a workshop last year #TechKnowDay and I saved this one about Swift for beginners in my draft. I didn’t have a chance to participate, but I followed the instructions on the slide of the project: https://github.com/ananogal/Workshop-Swift-for-beginners

I took the chance to do some automation on this project and created the scenarios (without BDD) here:


It is really basic and simple, but it is a start point for everybody who wants to learn how to create the tests.

You can also record the actions, just open your project on Xcode:

  • Create a New Target


  • Type a name for your UITest target


  • Select the UI Testing template


  • Then you just need to click inside of the test function and the record button (red circle) will show up on the bottom of the screen


Thank you Ana for this great workshop !

Deep learning with python

Hello guys, last year I joined to a day of workshops from #TechkNowDay here in London. This workshop is about deep learning with python and I am able to share the power point explaining the exercise with you.

You can download the Power Point presentation here and the list of files for this exercise on this link.

Nice coding everyone !

Thank you so much for the workshop and all the explanation Bianca Furtuna !

Injecting cookies in your testcafe automation

Hello guys,

Today I am going to post an alternative to authenticate without going throught the login page. I have done this before generating a token for Keycloak to authenticate, but in my last project I generated the cookies and added them as a header with testcafe intercepting the HTTP requests to the website.

This is useful for when you don’t need to test the login process or you have a separated feature to test the login page. Then you will be able to save time when running the automation and avoiding to have to sign in every time you launch the scenario.

I had to take this approach for another reason as well, which was this bug here that happened because TestCafe uses a URL-rewritten proxy internally and this proxy is forced to handle cookies manually because the URL of the tested website is changed during test execution.

You will need to add this in a Before hook and generate the cookies before running the scenarios.

So first, install keygrip and cookies in your package:

npm run keygrip base-64

Second you will need to create the cookie based on your authentication process. For example if your cookie is generated with a json like this. You will also need to set the cookie like this and then you can add it in your utils/helper/support class:

import { RequestHook } from 'testcafe';
import Keygrip from 'keygrip';
import Base64 from 'base-64';

class addCookie extends RequestHook {

    constructor (requestFilterRules) {

    async onRequest (event) {
       const cookieName = "name-of-your-cookie-here"; //Change the value with the name of your authentication cookie 
       const cookieSigName = "name-of-your-cookie-here.sig"; //Same as above, but this is the signature cookie 

       let cookieValue = { "name":"username", "email":"username@email.com" }; //Here you have the value that is inside the cookie 
       cookieValue = Base64.encode(JSON.stringify(cookieValue)); //Encode to Base64 the string if you need it 

       const keys = new Keygrip(["SECRET_KEY"]); //Here you will add your secret
       const hash = keys.sign(`${cookieName}=${cookieValue}`); //This is where you are going to sign the cookie with your secret key

       const myDate = new Date();
       event.requestOptions.headers[cookieName]= `${cookieValue};expires=${myDate};domain=${domain};path=/`;
       event.requestOptions.headers[cookieSigName]= `${hash};expires=${myDate};domain=${domain};path=/`; 

    async onResponse (event) {
       // Anything you need to add when you have the response 



You will need to import the page class and then in the feature level:

import addCookie from 'add-cookie.js';

const setCookies = new addCookie(/https?:\/\/your-url.com/);

fixture`Your Feature`


This is just an idea of how to skip the login screen page when doing automation and saving you sometime, but there are some other suggestions as well, like generating the token and add them to the header.






Chaos Engineering: Why Breaking Things Should be Practiced

Hello guys,

Last week I went to the WebSummit 2018 Conference in Lisbon and I managed to join some of the AWS talks. The talk that I am posting today is about chaos engineering, which specifically address the uncertainty of distributed systems at scale. The aim of this practice is to uncover the system weakness and build confidence in the system’s capability. 

The harder it is to disrupt the steady state, the more confidence we have in the behavior of the system.  If a weakness is uncovered, we now have a target for improvement before that behavior manifests in the system at large.

Today I am going to post the video on the exact moment that this talk starts.


This talk is presented by AWS Technical Evangelist Adrian Hornsby.

You can find tools to help you with the tests in this repo:

How do you help developers to test ?

Hello guys,

I have joined to some webinars from Test Masters Online, not sure if you heard about them, but this one really called my attention. The title looks a bit extreme, but you will see that is more about how testers and developers can work together to improve the quality of the team. The ideal is to have specialised QAs that can teach developers about automation, performance, security tests and so on. It is more about giving awareness about tests when developing.

The challenge nowadays is changing the developers mindset to contribute along with QAs with the automation tests and also getting support from the managers (which is something that I’ve always highlighted). If you want a team without a bottleneck and where everybody is max contributing for the quality and speed of the deliveries, then yes you need to think about a team sharing all the responsabilities and having a specilised person to guide and teach.

Basically you will see how Joel Montvelisky discusses the issues which prevents software developers to test, and what testers can do to change that.

Thank you !! See you in the next post 🙂

Using Artificial Intelligence to Speed up your Test Automation

Hey guys, today I am going to share with you this awesome webinar that I watched last weekend ! I suggest to follow IIST as they are always sharing good webinars about test.


Building a sudoku game with Kotlin

Hi guys,

Today I will continue the series of posts related to the workshop I attended during the #TechKnowday here in London. This one is to learn Kotlin building a sudoku game. So, basically Ana left available on her Github the initial parts and the solutions.

The instructions with the steps are available here. Below you can find the exercise done in parts:

You can find the first part here: https://github.com/anikiki/sudoku-init-part1

The second part:  https://github.com/anikiki/sudoku-init-part2

And the third part:  https://github.com/anikiki/sudoku-init-part3


If you are wondering what you have done wrong, you can check the solution for each part below. Don’t cheat, this is for after you have tried the exercise by yourself first:
