As the number of tests for a program continues to increase, it is no longer sufficient to know that all tests passed or which test failed. Other questions start to become important: were some tests inadvertently disabled? which tests were skipped? how did the duration of a test evolve over several versions of a program? Existing build platforms, such as Azure Devops, can help with test management, but in order make use of their features, we need to extend the Racket unit test library to report the test results to the build pipeline.
I wanted ActivityLog2 to show that my New Zealand skiing run started at 10am, rather than showing 6am, which is the local time in Western Australia, where I live. This feature took a long time to implement, plus it required a surprising amount of effort, and this blog post describes some of the implementation details.
A HeatMap chart allows displaying a collection of GPS activities on a map and it is a nice way to visualize GPS data. On-line tools provide this functionality, but I wanted to implement my own, displaying heat maps using data from my own computer, without having to upload it to another website.
The Racket source code is distributed under LGPL and this means that any proprietary Racket application distributed must also provide a way for the user to re-link an updated Racket runtime and produce a new executable for that application. In this blog post we’ll explore how to achieve this.
