**Battling your Biased Brain**
Ever heard of the IKEA effect or the bandwagon-effect? In our efforts to delivering great software, there are numerous occasions where our brain tries to trick us. Don’t fall for them!
In this talk we will dive into some well-known and researched cognitive biases that impact our judgments in our day-to-day jobs as software creators. When do they typically occur? And why are we falling into these traps from time to time?
After this talk you’ll have a better understanding of how your brain tricks you, how to make better decisions and in the end how to deliver some great software. A word of warning; during this talk you may get tricked!

**About Peter Wessels**
Peter Wessels is a Java Developer, Speaker, and Teacher at Info Support in the Netherlands. In addition, he leads the Java Community within Info Support. He loves working with talented people to develop software that's not only effective but also fun to create. In his career, Peter has worn many hats, from lead engineer and project manager to scrum master and product owner. As a speaker, Peter has had the privilege of presenting at prestigious events such as Devoxx UK, J-Fall, and Developer Week.

**Managing Test Data**
Have you ever tried to troubleshoot an issue taking a looking at the log files? I bet you did! And it turns out the issue is related to data usage because, you know, users will use real data! Developers won't! A good thing about your recent troubleshooting is that you can understand the data. It's not a bunch of numbers or UUIDs in the name field. How about your development environment? Probably you use either hard-coded data or random strings.
This talk will show you how to manage testing data in two different ways.
The first way is the creation of a Test Data Factory approach, where we will use the Factory Pattern to easily create any objects we want with understandable and reliable data. This approach will make you in control of your own data, so you can find any bug in the early stages of the SDLC and the DataFaker library will help us to generate good random data in every execution.
In a second way, we will apply the Data-Driven Testing approach, where the same requirement can be applied to different sets of data, generating different results. This approach can reduce the amount of code and the execution time. With the support of JUnit 5 you will learn how to do it in different ways: value source, internal method source, external method source, argument provider, and CVS source.
You will learn how to write Data-Driven tests using JUnit 5 in a SpringBoot application in the integration layer, using the Test Data Factory approach to create necessary and reliable data.
