 ## Work on the internals
 
 We did a lot of refactoring!
 Most of it was focussed on [tests](https://github.com/igraph/rigraph/pulls?q=sort%3Aupdated-desc+is%3Apr+in%3Atitle+%22test%3A%22+is%3Amerged), as [previously explained on this blog](/posts/2025-03-04-refactoring-test-files/): merging some test files to ensure alignment between R scripts and test files, refactoring test files for better readability and future debugging, updating the testthat usage by removing old expectations.
