Unnecessary Unit Tests

Snowflake Connection Provider

Hi,

What do snowflakes have to do with software development?

Strange question, I know.

But I had to ask myself this recently.

I was going through the code.

I wanted to understand which connection pools we have and how they are configured.

That’s when I stumbled upon a connection pool named SnowflakeConnectionProviders.

Huh?

What is that supposed to be? And how is it used?

And why is it a HashMap<String, IConnectionProvider>?

Super Boring Topic

Hi,

Yesterday, I published an article about the Assert class from Spring . And in May, at the Developer Meetup in Essen , I also talked about the class.

But actually, it’s super boring.

For those who don’t know:

It offers a series of simple “assert” methods. For example, instead of

if (someVariable == null) {
  throw new IllegalArgumentException("someVariable must not be null");
}

we can write:

Assert.isNotNull(someVariable, "someVariable must not be null");

Incredible.

Spring's Assert Class: The Smart Way to Validate

There are many ways to ensure your code does what it’s supposed to do. Java even has a built-in assert language feature for this very purpose. And then there’s Spring’s Assert class. But why should I use this? In this article, we delve deeply into the subject and explore the advantages of using this class for validating your data and arguments.

Why Use Assertions at All?

Before diving into the details of the Spring Assert class, let’s briefly clarify the significance of assertions. Assertions help us verify the correctness of our code at runtime. They are an essential tool for debugging and testing. This is particularly useful when you’re working with multiple developers on a project and want to ensure that the delivered data and parameters meet expectations. When this is not the case, we want to terminate our application and throw an exception.

Outch 😵

Hi,

Change hurts.

The sentence is somewhat jaded.

But it became clear to me again a few weeks ago.

Toni, an external DevOps Engineer (shoutout to you 😉), was new to the team.

On his website he writes, “As an expert in Developer Experience, my goal is to create an ecosystem for high-performance & innovatively-acting development teams.”

And he lives it. There is also more than enough to do. And we want to tackle it!

Open Session in View (OSIV) in Spring - Enable or Disable?

If you are working with Spring Boot and Hibernate, you have undoubtedly come across the term “Open Session in View” (OSIV) or its corresponding property open-in-view. But what exactly does this option do, and how does it affect your interaction with the database? Should you enable or disable it? In this article, we delve deep into the topic and shed light on its functionality and differences compared to other approaches.
