If you’re fed up with the hassle of writing and maintaining assertions by using XML data set files, you’re in the right place! The Introduction to AssertJ-DB course shows you how to replace those cumbersome data set files with reusable assertions. In short, this course will help you write assertions which are easier to read, write, and maintain — saving you both time and effort.
Why AssertJ-DB?
When it comes to writing assertions for the data found from a relational database, AssertJ-DB is a better choice than DbUnit because it makes your work easier and helps you to save your precious time (which you cannot get back). In other words, you can focus on what matters instead of wasting your time on fighting with your assertion library.
To be more specific, AssertJ-DB helps you to:
XML data set files often contain duplicate metadata and test data. That’s why tests which use external data set files are typically difficult to maintain. If you use AssertJ-DB, you can avoid this hassle entirely by writing your assertions with Java.
If a test contains multiple assertions and one of them fails, you may not get all the information you need because it’s possible that some assertions weren’t run. If you use AssertJ-DB, you can collect all assertion errors by writing soft assertions.
Instead of repeating the same assertion multiple times, you can remove the duplicate assertion from your test suite by putting it in one place. As a bonus, custom assertion methods also highlight your application’s business rules, making tests clearer and more meaningful.
Why Should You Learn From Me?
My name is Petri Kainulainen, and after using DbUnit for over 10 years and writing thousands of integration tests which use XML data set files, I was never fully satisfied with the results. Those tests were tedious, difficult to maintain, and drained both my time and energy. But for years, I thought DbUnit was my only option.
That all changed when I discovered AssertJ-DB a few years ago, and since then, I haven’t looked back. AssertJ-DB has shown me a better way to:
- Eliminate duplicate assertions that make tests hard to maintain.
- Write clean and readable assertions that keep my feedback loop short and efficient.
Best of all, because I don’t have to deal with XML, writing database assertions has become enjoyable again. AssertJ-DB transformed my approach to testing, and it can do the same for you.

If you aren’t living in the European Union, I cannot sell this course to you. I simply don’t have the time or money to ensure that I am not breaking any tax laws, which, by the way, are literally changing all the time. If you want to buy this course and you aren’t living in the European Union, drop me an email. If I get enough emails, I will check if there is something I can do to fix this problem.
