These are the plugins reviewed. ### Note Refactor - [[note-refactor-obsidian|Note Refactor]] - Uses **mocha** - Nice break-up of tests - Nice test descriptions - Mock of date - Sample data file ### Dataview - [[dataview|Dataview]] - Uses **Jest** - Takes noticeable amount of time - lots of tests - Demonstration:Can run individual tests - Demonstration:Can explore behaviour of the code ### Linked Data Helper - [[linked-data-helper|Linked Data Helper]] - Uses **Jest** - Test data stored in repo - Nice helper functions so tests are readable - Uses Jest snapshot testing to capture complex output > I have to say, it is really a good feeling that I can just run the tests and see that I get the same output instead of needing to run the commands inside Obsidian. > > @koala/@kometenstaub ### Tasks - [[obsidian-tasks-plugin|Tasks]] - Uses **Jest** - Nice data-driven tests - Nice integration with GitHub Actions - Nice integration with git: [lefthook.yml](https://github.com/obsidian-tasks-group/obsidian-tasks/blob/3210fffba1afba3520366531f084adab268f0622/lefthook.yml) - Shows mocking of dates in Jest - General comment: quite a lot of repetition of code in the tests, at the time of the talk - Demonstration: using 'extract method' refactoring %% Hub footer: Please don't edit anything below this line %% # This note in GitHub <span class="git-footer">[Edit In GitHub](https://github.dev/obsidian-community/obsidian-hub/blob/main/04%20-%20Guides%2C%20Workflows%2C%20%26%20Courses/Community%20Talks/Plugin%20Testing%20for%20Developers.md "git-hub-edit-note") | [Copy this note](https://raw.githubusercontent.com/obsidian-community/obsidian-hub/main/04%20-%20Guides%2C%20Workflows%2C%20%26%20Courses/Community%20Talks/Plugin%20Testing%20for%20Developers.md "git-hub-copy-note") | [Download this vault](https://github.com/obsidian-community/obsidian-hub/archive/refs/heads/main.zip "git-hub-download-vault") </span>
