Testing

webmockr v2 is here. You can find the source at https://github.com/ropensci/webmockr, and the docs at https://docs.ropensci.org/webmockr. There’s some big changes in this version; most importantly a breaking change, thus the major version change this time. Here’s a run down of the important items in this release.

Under the hood we’re using withCallingHandlers() to handle different types of errors, throw warnings, etc. For example, wi_th() only accepts types list and partial, so fails with this code: ...

I worked on a refactor of an R package at work the other day. Here’s some notes about that after doing the work. This IS NOT a best practices post - it’s just a collection of thoughts. For context, the package is an API client. It made sense to break the work for any given exported function into the following components, as applicable depending on the endpoint being handled (some endpoints needed just a few lines of code, so those funtions were left unchanged): ...

The R package vcr, an R port of the Ruby library of the same name, records and plays back HTTP requests. Some HTTP requests can have secrets (e.g., passwords, API keys, etc.) in their requests and/or responses. These secrets can then accidentally end up on the Internet, where bad people may find them. These secrets are sometimes called “truffles”. ...
