Conditionally Disabling and Filtering Tests in JUnit 5

Billy Korando Articles, Development Technologies & Tools, Effective Automated Testing With Spring Series, Java, Testing 9 Comments

I’m in the middle of several talks on JUnit 5, so it’s safe to say that JUnit has been on my mind lately. In the last article in this series, we covered how to use test interfaces to encourage good behavior.

In this article, we look at the improvements the JUnit team has made to filtering and conditionally disabling tests in JUnit 5….

Encouraging Good Behavior with JUnit 5 Test Interfaces

Billy Korando Articles, Development Technologies & Tools, Effective Automated Testing With Spring Series, Java, Spring, Testing 2 Comments

JUnit 5, released in September of 2017, is the first major release for the popular JUnit testing framework in a little over a decade. I recently presented on JUnit 5 at Lava One Conf in Hawaii in January. If you have heard about JUnit 5, but are not yet familiar with it, you can check out my presentation here, as well as the JUnit 5 User Guides.

While researching for my presentation, one new feature in JUnit 5 really caught my eye was the ability to declare tests on default methods in interfaces. This feature caught my eye because two issues I frequently face are encouraging developers to write automated tests and promoting consistent patterns across the enterprise. In this article we are going to look at how test interfaces can help accomplish both of these goals.

JMeter Performance and Load Testing

Todd Horn Articles, Java, Testing, Tutorial 1 Comment

Apache JMeter is an open source application tool designed to load test functional behavior and measure performance on static pages, dynamic resources, and web applications. It can be used to simulate a heavy load on a server or group of servers, database, or network to test its strength, or to analyze overall performance under different load types.

In this post, I’ll provide an introduction to JMeter with the goal to get you up and running (and testing!), more quickly and easily…

Encrypting Working Files Locally in Spring Batch

Rik Scarborough Articles, Development Technologies & Tools, Java, Spring, Spring Batch Leave a Comment

It seems that quite often we read stories in the news about computer systems being cracked and data being compromised. It’s a growing concern that should be a consideration for everyone in Information Technology. There is probably not just one solution that will keep all data safe, but hopefully small efforts in many areas will provide us with the best possible solution.

In this post, I show a solution for encrypting sensitive files for local use with Java’s Encryption library & tying directly into Spring Batch readers and writers.

The Scenario
Recently we began writing a Spring Batch application that would handle sensitive data. The application servers were set up with some very good, basic security, but we felt the data could use some extra protection.

The data would be delivered to the company on a well-protected and secure FTP server. Mark Fricke did an excellent post recently on Spring Integration and Spring Batch in which he discusses downloading an encrypted file from a FTP server and decrypting it. Unfortunately, this was not exactly the problem we had. We needed to download a unencrypted file, but never write it to the Application Server unencrypted. But, we needed to be able to read that file and process it in Spring Batch.

Using Java’s built-in cryptography, we are able to extend Spring Batch to encrypt the file on the disk and then read that file in a Spring Batch Reader. In addition, we can write the results out as an encrypted file then transfer that file back to the secure FTP server as clean text.

Wow, that sounds like a lot and will be a really complex solution. Actually the code turned out to not be all that complex. This solution relies partly on the Delegate Pattern I wrote about before, so I will be using the same code I developed for that and just showing the changes here. Please refer back to the original post…
