D90 is a long-running Natural/Adabas application that supports core driver and vehicle licensing services. We’re moving it from its existing IBM mainframe environment to Linux running on AWS, which raises an obvious question: will it still work the same way? The application launched in the 1990s and has been refined ever since. Moving it to Linux running on AWS requires adapting to a different platform: encoding, sort order, I/O behaviour, and other assumptions built into the code over decades. We are adding Cucumber scenarios using Software AG’s browser-based Natural interface with Capybara and Playwright to ensure key features work as expected. ...

How Ruby can do what you don’t expect Ruby is a very clever language. It will take the code you’ve written and do it’s best to make sure it runs. Take for example the following method call: method_one('Hello', param_two: ' world') That looks simple enough as it takes two arguments, one positional and one keyword. Now, lets take a look at what the method is actually doing: def method_one(param_one, param_two) p param_one, param_two end Interesting. At first glance it might appear that this method would print Hello world, but there is a subtle difference between how the method has been defined and how it is called. Let’s see what it actually outputs: ...

Ever had to create users in MongoDb Atlas in AWS for use when making database enquiries in a functional test written in Ruby? Ever wished you could leave it to the test pack to check if one already exists and create one when required, instead of hand cranking a new one every single day of your life? Well now you can!!! But, first things first What is MongoDB Atlas and what do its users do? ...

When trying to get an upper or lower value for a certain field in an object can be cumbersome. But when using the max_by method, this can actually be done quite elegantly. For example: persons = [ { "name" => "John McJohnson","age" => 34, "topScoreAtBowling" => 205}, { "name" => "Davey Jones","age" => 304, "topScoreAtBowling" => 300}, { "name" => "Willy Wonka","age" => 50, "topScoreAtBowling" => 200} ] If we had a bowling competition and wanted to see who had the topScoreAtBowling field, rather than looping through the array and looking at each object, we can simply use the max_by command as follows: ...

TiL how to toggle Ruby scenarios to be run using CI pipeline secrets Scenario In a relatively niche scenario, we have functionality that is being temporarily removed while new code is being developed. While we still want to keep our current scenarios for function X to use them again when it’s reintroduced, if they are left to run in our pipeline, every build will fail until it is reintroduced again. ...
