Leading by example

Hello guys,

Today I am going to post something interesting that I learned through time with my work experience. This time I’m not talking about technical skills, I’m talking about the soft skills and how you can be a better person every day by learning from the constructive critics and ditching the destructive ones that don’t give you any benefit.

I am also sharing what some successful companies are already doing in the Silicon Valley which Jacqueline Yumi Asano explained in her article (it is in Portuguese, but you can check it bellow in the Resources part).


Inspire people


Say sorry, you are not a machine and you are going to fail at some point

If you want to be a trustworthy person at your workplace, you need to show that you are fair and you recognise when you fail. Saying sorry will show that you are humble enough to have the trust of anyone.


Strength the individual

Nothing is more empowering than supporting people to learn something and improve themselves. Everybody wins when this happens. Ask yourself if 20% of your time is about learning or you just do the same task over and over again. Do you have challenges in your company ? Are you growing in this company ?

You might be asking how can you identify if a company will improve you or not before even starting there? Check how they write their specs and roles. Are they asking for specific technologies or are they looking for generalist professionals ? A good company will look for someone that is a machine learning person and not someone that has a fixed technology in their skillset. That means the company will follow the latest technologies and you will be learning most of the time.

We don’t’ assign the work for our developers. They assign up for work


Don’t under estimate the power of the vision and direction

Do you have a clear version of your goal ? Does your company is taking you to this goal ? This is extremely important for your future and you don’t have time to lose. So, double check if your company helps you to achieve this goal and if you have a clear vision and direction to follow.

If not, there is not too much you can do apart from start looking for a place where you can clearly see it leading you to your goals in, let’s say, a years time.


Get away from tyrant bosses, look for a strong bond of trust on both sides

If you ever worked in a place where your manager use his lead position to decide something rather than arguments, what are you even doing in a place like this? It is definitely a toxic environment and with this lack of trust it is better to look for something new because discussions and arguments would be pointless. Your opinion will mean nothing, even if you have arguments, analysis and your own carrier experience. Your manager will always ignore what you are saying.

Free choices matter and you should work in a place where your opinion is not invalidated.

Our product is great because we show why we are recommending
an specific insight. This way we build trust.
François Lopitaux, Director of Product, Salesforce


Surround yourself with passionate, but not blind people

Passionate is different from blindness. I just want to highlight that I have found many people that come across as passionate people but in reality they were completely blind and never accepted to have failures on their ideas/projects/implementation. This is quite common among developers, for that reason there is this assumption that a QA will always be a developer enemy, since it is part of our job to show bugs on their implementations.

A smart person knows how beneficial is to have a constructive critic and feel glad to have them. So, surround yourself with passionate and smart people. Be smart, take responsibility, accept the failures and improve them.


Get others opinions to empower people

I can only see advantages on doing that. Share knowledge as soon as possible with everybody in your team. Is this a new feature ? So, get everybody together and expose your idea, get others opinions. Don’t ignore them, every idea has a value. You can find bugs in the early stages and also this builds an ownership feeling.

Does the company take your opinion into account ? Do you feel that you have autonomy ? There is nothing more empowering than showing that you care about everybody opinions. Everybody feels valued and this will increase the trust on your work since they know that they can be honest with you.

How to use mind maps to clarity your tests

To improve the communication about a project you don’t need to have infinite docs and articles. For someone who is starting or to quick understand the product you need to have something smaller, prettier, and more focused to the audience. Mind maps are a lightweight form of testing documentation, because communicating effectively with the team is the key of a good quality implementation.

Revealing the Complexity of a Problem

Imagine that you have to test an app. You know that you need to test the functionalities and if the behaviour of the app is not clunky and unstable. You can have articles on Confluence explaining the behaviour of the app or you can have a mind map which is more focused and simple.

For example:

Click to expand


This mind map will help you to remember of all of the type of tests that you can perform on a mobile app.

The mind map communicated the logic of how our code would be written without the need of looking at code. It can cover all of your use cases and extract connections in a way that would have been difficult to do in a list.

When creating the mind map you can follow Heuristic Test Design, which is a model of tests with different patterns of quality criteria, techniques, elements and environment. It helps testers to remember and design different combinations while creating the test plan.


Using mind maps for regression tests

You can use mind maps for so many things, for example as a guide to your regression tests. I think it is far much more easy than reading a list of checklists. Also, it helps people who are just arriving at the company to understand the flow and the connections across the features. This guide helps you to decide whether what’s happening is something you should expect. Not everybody agrees about having mind maps for regression tests which I can understand why, but you can decide this with your team.

Imagine that you have a checklist like this:

You need to follow this checklist to be sure your release is good to go, but imagine that you have a map to follow, wouldn’t be more clear and easy to understand ? You can find the mind map correspondent to this checklist here:

Click to expand

When a button changes, for example, the mind map should be the first thing to look at. You can check if nothing was changed below or up that node (feature). You look at the parent node to see what pressing the button did and make sure it still does that. You update the mind map with the new button shape so that future testers know how it works now.

Mind maps help us test not just the change at hand but the consistency of that change relative to the rest of the product, the product’s history, and the feature’s purpose.

 You should share this process and ask for the development team input their thoughts and this will build trust in the regression pack. Also as I always recommend, share and review always. You are not working alone and it’s important to remember that we are not machines and we have blind spots which can be solved by the involvement of a properly engaged team.
You can use some of these free tools to create your Mind Map, I usually prefer the online ones, but feel free to choose the best one for you:





Blockchain Testing Tools

February 16, 2018 Leave a comment

If you are wondering what Blockchain is, I will give you a quick introduction. Blockchain is a data structure that is distributed at once in many different places and as you can’t ever delete from it, it is extremely difficult to make amendments. This makes the record more secure and more trustworthy.

So, what are the kinds of test that you can perform ? You can use the traditional testing, since it is just normal development work with normal testing criteria. So, boundary value analysis, decision tables, test driven development and behavior driven development techniques.

There is also a set of questions that can help you to build your test scenarios, for example:

  • How does it handles valid and invalid inputs?
  • How does it cope with a wide range of input data?
  • How does it handle missing state, or existing state?
  • How does it handle error cases?
  • How does it handle security and access control?

You don’t need to test the Blockchain because the algorithms are well-established, because it is a distributed system, but the transactions still require some kind of validation. For example, you may need to check if your transaction is valid before it can be approved. There are approval authorities for different blockchains, and they must test the integrity of the transactions.


What is Smart Contract ?

Smart Contract is an API and defines the rules for transactions in a Blockchain network. A Smart Contract is a set of rules in the form of programmable constructs that are capable of automatically enforcing themselves when pre-defined conditions are met.

It has public functions which might be called by anyone registered on the Blockchain network. However, unlike a traditional API, a Smart Contract cannot call external web APIs.


What do you need to know to test Ethereum Smart Contracts ?

Test automation requires that the platform being tested must have hooks so that external automated scripts can instruct the platform, observe the outcome, and verify that the outcome is what is expected. Legacy platforms in banking often do not have these hooks, and that makes automation much more difficult. When you compare smart contracts to older software used in banks, you can automate testing much earlier and much faster.


I will show some of the tools that you can use to perform tests on Blockchain applications:


Ethereum Tester

This github has a project for you to test Ethereum Blockchain Applications. You will need to clone Eth-Tester. The Eth-tester library strictly enforces some input formats and types.



Truffle is one of the most popular Ethereum development frameworks and has testing functionality, it is a scaffolding framework for smart contracts used by UI builders. You have the ability to write automated tests for your contracts in both JavaScript and Solidity and get your contracts developed quickly.


Ganache is the most-used library for testing Ethereum contracts locally. It mocks a blockchain that gives you access to accounts you can run tests, execute commands, etc.



By default tests run against an in-memory ethereum blockchain and as you can see here Populus supports writing contracts that are specifically for testing.



Manticore is a symbolic execution tool for analysis of binaries and smart contracts. It is supported on Linux and requires Python 2.7. Ubuntu 16.04 is strongly recommended. It has a Python programming interface which can be used to implement custom analyses. You can see more about here on the wiki.


Hyperledger Composer

Hyperledger Composer supports three types of testing: interactive testing, automated unit testing and automated system testing. It’s a framework for rapidly building Blockchain business networks on top of a Blockchain platform, such as Hyperledger Fabric.

This framework allows you to automatically deploy the business network definition, and then interact with it by submitting queries and transactions in order to test how that business network really behaves.


Corda Testing Tools

Corda is a blockchain-inspired, open-source distributed ledger platform. There are several distinct test suites each with a different purpose: Unit tests, Integration tests, Smoke tests, Load tests and other. These tests are mostly written with JUnit and can run via Gradle.



This tool BitcoinJ allows you to interact with Bitcoin connecting directly to the bitcoin network. So, you can simulate send and receive transactions in real time, also you don’t need to have a local copy of the Bitcoin Core.

You can follow this guide to get start with this tool.









Quality Engineer Mindsets

February 7, 2018 4 comments

Hello guys, today I am going to post about the different types of QA mindsets that exists and how you can identify them. As a QA Engineer your aim is to improve the quality of the product from the very beginning. If this is the main objective why we have so many different titles for a professional that works in the QA area ?

This is because you can find QAs that focus more on the business and product side of the project. Others are more technical and focus on the automation and improving the quality and the release speed of the product, and some others that like to do both, the business and the automation part.

What is the future of the QA professionals ?

We can notice that some QA pros are instead of running the tests and handling the hands-on work, they are transitioning into a more consultative and distributed role to help developers learn how to write better tests and improve their approach to screening for quality. Because, at the end of the day, developers are still developers and while they’ve not been trained to look for quality issues, they’re going to miss things.

QAs pros just need to adapt to a rewritten organizational hierarchy—and a completely different mindset about testing objectives.

You can spread this mindset to your entire team, not only QAs. Uncaught bugs and untested features could easily gradually destroy confidence in the new product and lead to a loss in traction. Knowing your development team can not only ship features quickly but avoid these costly mistakes may be the edge your app needs.

With the latest trends toward faster and more efficient software teams having developers doing their own quality assurance is more important than ever. It takes dedication and practice to build a QA mindset but the benefits of how it can help your team and product make it worth.

I am going to separate the QA mindset profiles following the market trends.

Traditional QE

  • Perform Manual tests only
  • Focus more on the business part of the project
  • Able to perform Functional tests
  • Create a lot of documentation, like Test Plan and Test Suite
  • No contact with the feature until is Ready to Test
  • Don’t have integration with development team


Agile QE

  • Perform Automation and Manual tests
  • Focus on the business and the technical part of the project
  • Able to perform Functional tests
  • Create Test Scenarios for automation and for the feature
  • Help the Developers and PO to write the scenarios upfront
  • Have some kind of integration with development team


Pos Agile QE

  • Perform Automation tests only
  • Responsible for configuring CI/CD
  • Focus on the business and the technical part of the project
  • Create Test Scenarios for automation and for the feature
  • Able to perform Functional and Non-Functional tests
  • Help the Developers and PO to write the scenarios upfront
  • Share the automation knowledge with the developers


Developer QE

  • Developer with interested in QA
  • Implement the code and the automation code
  • Focus on the implementation, but also on the quality
  • Tend to over complicate the Automation project
  • Has a QA curious and critical thinking when implementing
  • Able to perform Functional and Non-Functional tests
  • Test his own implementation thinking on the end user


There is also a misconception about QE:

Wannabe QE

  • Doesn’t have a QA background
  • Worked only on one type of industry or only on crowd tests
  • Usually doesn’t know anything about type of tests (Functional or Non-functional)
  • It only knows about the business related to the background they have
  • Doesn’t know the importance of trivial tests like boundary tests
  • Doesn’t really have interest about QA best practices

What I suggest for this last one is to study. If you want to work in this area, don’t undervalue the professionals that have studied and continue studying everyday to be here.

In general QEs are extremely curious and go always for the simple and cleanest solution. They are skeptical and nitpicker which are the most annoying character of a normal human hates to posses. But when it comes to a testing profession, these becomes a must have characteristics for a tester.

Starting with security testing

January 17, 2018 Leave a comment

Security test is a group of measures to secure an application against unforeseen actions that can cause the application to stop or to expose data. These actions can be intentional (caused by hackers) or unintentional. So apart from the obvious reasons why you should be sure your application is not vulnerable, you have at organization level:

  • Responsibility
  • Corporate responsibility
  • Regulatory bodies
  • Compliance
  • Legal
  • Financial

And at the technical point of view:

  • Integrity
  • Authorisation
  • Confidentiality
  • No repudiation
  • Availability
  • Authentication


So, what should you do when creating some security tests ?

You need to seek permission before you start, then try to learn on sandbox applications or virtual machine, not real environments. Keep focused when doing the tests and prepare in advance threat modelling/survey sessions.

The web security vulnerabilities are prioritized depending on exploitability, detectability and impact on software.

  • What is needed to exploit the security vulnerability? 

Highest exploitability when the attack needs only web browser and lowest being advanced programming and tools.

  • How easy is it to detect the threat? 

Highest being the information displayed on URL, Cookies, Form or Error message and lowest being source code.

  • How much damage will be done if the security vulnerability is exposed or attacked?

Highest being complete system crash and lowest being nothing at all


Threat modelling

A range of techniques for analyzing the security of an application, examples:

  • Data flow diagrams
  • Threat categorization
  • Trust levels


You need to understand how the data is manipulated in all levels:

  • Entered
  • Stored
  • Transported
  • Presented


What are the assets you want to protect, which can be physical or abstract:

  • Reputation
  • Customer data/client
  • Corporate data


Threat Modelling – STRIDE

  • Spoofing
  • Tampering
  • Repudiation
  • Information Disclosure
  • Denial of service
  • Elevation of privilege


There are so many ways to check if your application is vulnerable, like:

  • User Inputs
  • Error messages
  • URLs
  • Files and attachments
  • Request/Response headers
  • Insecure User Credentials
  • APIs
  • Cookies


If you want to test injection flaws for example, you can exploit by submitting untrusted data, also it is very common and easy to exploit causing extremely damaging problems if not fixed. This type of issue can affect UI elements, URLs, parameters in requests and cookies. Examples of Injection are SQL Injection and Cross Site Scripting,


Broken Authentication and Session Management

The causes of a insecure session management may lead to session hijacking, spoofing or fixation and to escalation of privilege. Fairly common, simple to exploit, but can have wide ranging and damaging impact. It can affect session tokens, user credentials, request parameters.










How to integrate Guice + Cucumber + WebDriver

December 18, 2017 Leave a comment

Hello guys,

Today I am going to post about something that I have been studying. So, in this project you can have an idea of how to implement Dependency Injection using Guice, a Google framework which helps you to reduce the need of new in your Java code. I found only projects that have only the Guice + Cucumber integration or only the Guice + Page Objects, so I think this one might be a good example of how to integrate everything.

Also, the project contains Page Objects and a Driver Factory, so you will be able to include other browsers and implement each one’s singularity when creating the browser, and also you still have the good practices of the POM.

I’ve added comments along the code, but feel free to ask anything or even suggest improvements.
