REST Assured: Automated Tests of Web Services

JUnit itself may be sufficient to develop unit test for monolithic applications. However, testing services may bring a lot of complexity and duplicate code to deal with requests and responses. The REST Assured framework provides a bunch of features to abstract the creation of requests and to parse and validate responses.

Mocks with Java: Automated Testing of Behavior

Sometimes it's impracticable to test some features of an application cause it may depend on external factors - such as databases or services which are out of the tester control - or simply because it's too complex to set up the scenario needed. Mockito comes up to solve this problem, helping to easily simulate returns of methods which are not supposed to be tested, and so letting the tester concentrate on the real test case.

TDD with Java

Testing applications manually may demand a lot of time and workforce that might be used to improve the software. In addition, as changes are made, bugs may be introduced to features already tested, making necessary the test the whole system at each release. Obviously, this approach is undesirable for any software that needs to be competitive in the market. The TDD approach helps to produce more reliable software as it guarantees that each new feature will be tested and will not crash the previously written test cases.

COBOL: Getting Started

Although the language has been developed in the 50s, it continues to be maintained and evolved as many systems today rely on it to process transactions. Meanwhile, programmers mastering it become rare. Out of curiosity and thinking of that as an opportunity to know a real highly demanding skill, I took this course.

JAX-RS and Jersey: Mastering the Development of REST Web Services

It seems RESTful services have become the rule when building new service-based solutions. Here I could learn the entire lifecycle of a web service with the Jersey implementation of JAX-RS API, from the test phase to deployment. I was introduced as well to some tools and libraries to make that task easier, like Grizzly, to quickly build a server environment; XStream and JAXB, to convert between XML and Java objects; and Gson to do the same with JSON.

Swift 3: iOS Development with Xcode

Seeking to be in touch with the public we needed to make services available in a convenient and easy-to-use way: through their smartphones. Here I have learned the basics of Swift language and Xcode IDE, the tools needed to write safe, fast and accessible native software for one of the most popular smartphone platform.

HTML 5 and CSS 3

Many solutions these days are based on web. In order to make friendly and responsive user interfaces, it is important to have strong knowledge of HTML and CSS. I've used these two since I was beginning to develop web pages and I've updated myself in an "on-demand" fashion. So, I decided to take that course to know if I was not missing any concept introduced over time.

PHP and MySQL: Fundamentals of Creating Web Applications

Many enterprises use PHP on their solutions as it is easy to learn, very powerful and has a large community with which you can discuss or ask some question about the language. During this course I have learned how PHP can be easily integrated with MySQL, providing an inexpensive and complete solution to many kinds and sizes of business.

MySQL: Getting Started

Reliable and easy to use, MySQL is one of the most popular open-source relational DBMS. Knowing this DBMS specificities is always good when setting up a new project as you will have an alternative to the well-known paid DBMSs available on the market.

PostgreSQL: Getting Started

Working with that DBMS through an ORM has been a good experience. Although, the ORM was sometimes limited or inefficient when dealing with more complex data manipulations. So, I became interested to know more about that database and its native DDL and DML statements.

UML

Although agile methodologies can help to create and maintain software as fast as business changes happen these days, there are some complex and critical features that need to be well planned and documented in order to be maintenable. UML diagrams can be very effective to represent complex systems in a way every team player can understand.

Web Security: Vulnerabilities and OWASP

Government agencies often deal with sensitive citizen data. Keeping those data safe is mandatory in order to establish a trust relationship between citizens and the government. In that course I could improve my knowledge with practical examples of how to prevent the exploitation of software security vulnerabilities with SQL injection, brute force, cross site scripting and social engineering.

Java: Mastering Collections

The Java language has a very rich set of collection classes, each having its pros and cons. Mastering the differences between them could help one to produce safer code, wasting less time, as many useful behaviors and policies, such as data structures, algorithms and concurrency handling, are already implemented and well tested.

Java: Testing, JSF and Design Patterns Workshop

This workshop aimed to resume the entire lifecycle of a Java application, using TDD. Here I had to construct a simple Java application and its unit tests, using JUnit. Then, I evolved it to a JSF one, using Primefaces. I also practiced the usage of the Java reflection API.

Object-Oriented Programming: Best Practices in Java

Java is an OOP language and to leverage that one must know the concepts and best practices of this paradigm. Today it is not difficult to find pieces of Java code written in a procedural fashion. Here I revisited concepts of OOP, such as encapsulation, inheritance, polymorphism, cohesion and coupling. In addition, I learned how to increase flexibility of code with dependency injection.

Data Modeling

It's mandatory for applications which rely on structured data to have a data model that can be understood without any doubts. This course discussed about the entity-relationship model and how one can use it to transform a real business model into a relational model, using the normalization techniques to make future queries fast and consistent.
