In this lecture, we’ll present the IBM iX project quality approach, including coding guidelines, static code analysis, and testing automation.
Coding guidelines define our aligned best practices, which are enforced through architectural unit tests and SonarQube static code analysis. Furthermore, we used our company coding guidelines to create a set of custom SonarQube rules. Naturally, we don’t want to repeat the same mistakes on multiple projects. In our live coding session we’ll show how to create custom Sonar rules for Java. Utilizing a template project provided by SonarSource, we will create a new custom rule and accompanying unit tests.
These days testing our Java code is a must. However, it’s not that simple to do it right. In this workshop, we’ll explain why testing is important and what is the difference between Unit and Integration testing.
We’ll do a live coding session creating both Unit and Integration tests on a small Spring Boot application. We use a couple of libraries including JUnit, Mockito, MockServer, MockMVC, and Testcontainers. We’ll compare Unit vs Integration testing approaches and state their pros and cons. Finally, we’ll provide tips and best practices on when and how to develop both types of tests.
You probably heard the GraphQL buzzword quite often. But did you ever find the time to try it yourself?
This workshop will be a great opportunity to do exactly that. It is time to compare your usual REST APIs with GraphQL. After the difference is clarified, we will start off by defining a GraphQL Schema. Together, we will build a GraphQL server in plain Java from scratch. We will take a look at GraphQL resolvers and explain nodes and edges. Once we set up the service, we’ll also create a simple client. We’ll see how to perform CRUD operations using GraphQL queries and mutations.
