JMP Marketplace feature: JSL-Hamcrest add-in

Testing your JSL scripts just got a whole lot easier. We’ve built an implementation of Hamcrest for JSL, designed to help you write tests that are both powerful and easy to understand, complete with informative failure messages. With this add-in, you spot issues faster and improve your JSL more efficiently.

Justin Chilton (@Justin_Chilton) and I developed a JSL-Hamcrest add-in that brings the flexibility of Hamcrest into our in-house JSL testing framework. The result is a more streamlined and robust way to verify that our code behaves exactly as expected.

What’s available?

  • A variety of testing framework features you can start using right away.

  • Built-in help resources. Check out the Scripting Index in JMP and look for functions starting with the ut prefix.

Whether you’re a seasoned JSL coder or just getting started, this add-in makes testing more intuitive and less error-prone.

Watch the demo video and learn how to integrate it into your workflow.

 

Look for the JSL-Hamcrest add-in and others in the JMP Marketplace.
