  • GitHub repo jest

    Delightful JavaScript Testing.

    Project mention: Understanding Jest | dev.to | 2021-06-20

    You cannot completely neglect one essential area of software development: automated testing. There are many different testing libraries or test runners available for JavaScript. However, today we'll learn about Jest, a testing library developed and used internally by Facebook, that resembles Mocha the previous king of JavaScript testing libraries.

  • GitHub repo garden

    Automation for Kubernetes development and testing. Spin up production-like environments for development, testing, and CI on demand. Use the same configuration and workflows at every step of the process. Speed up your builds and test runs via shared result caching.

    Project mention: You Don't Need to Rebuild Your Development Docker Image on Every Code Change | news.ycombinator.com | 2021-05-31

    Garden[0] is tool we built (yes, I'm affiliated :)) that has a lot of this functionality built-in. Might fit your use case.

    We recently re-wrote the hot reload functionality to use Mutagen[1] under the hood and its insanely fast (<200ms anecdotally). It also does two way sync which can be useful. The old implementation used rsync but a lot of our Windows users struggled with that. So I figured I'd share in case that sounds familiar.

    What happens after a sync event depends on the stack, but we've had pretty good success with Entr[3]. We often have it watch a single file so that multiple watchers in a shared dev cluster don't eat up all the node's resources.

  • GitHub repo Python

    This extension is now maintained in the Microsoft fork.

    Project mention: Attention! As of today, updating the VS Code Python extension automatically installs proprietary software on your computer! | reddit.com/r/linux | 2021-05-11

    But I mean, this doesn't prevent you from writing an open source extension that runs regardless of which version a user chooses to use, right? Users who are using the open source version of VS Code aren't forced to install the proprietary version with PyLance. The old extension is open source and even had a release just 18 hours ago - https://github.com/Microsoft/vscode-python

  • GitHub repo generatedata

    Random data generator.

    Project mention: Self-hosted alternative to Mockaroo | reddit.com/r/selfhosted | 2021-05-24

    Maybe another self-hosted service could cover hosting and be integrated with the generatedata script as the datasource. Let me know if you find something. I was just using Mockaroo this morning and considering a paid plan.

  • GitHub repo mongodb-memory-server

    Spinning up mongod in memory for fast tests. If you run tests in parallel this lib helps to spin up dedicated mongodb servers for every test file in MacOS, *nix, Windows or CI environments (in most cases with zero-config).

    Project mention: Show HN: Mongita is to MongoDB as SQLite is to SQL | news.ycombinator.com | 2021-04-20

  • GitHub repo jest-codemods

    Codemods for migrating to Jest https://github.com/facebook/jest 👾

    Project mention: What UI testing framework do you use and what do you like/dislike about it? | reddit.com/r/Angular2 | 2021-04-29

    jest-codemods helped us a lot moving from Jasmine to Jest, removes most of the manual work

  • GitHub repo ts-mockito

    Mocking library for TypeScript

    Project mention: The Repository pattern with Typescript | dev.to | 2021-02-15

    There's a very cool library called ts-mockito, it works very well when you use dependency injection in your code (as we're doing now). It allows you to create mocks, stub function calls, and many other cool features, definitely check it out! I'm going to use it to test our AuthRepository.

  • GitHub repo testcontainers-node

    TestContainers is a NodeJS library that supports tests, providing lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container.

    Project mention: Testing in Node.js with Testcontainers | dev.to | 2021-03-13

    Luckily, Testcontainers is a great project that makes setting up external resources more comfortable by providing a programmatic interface to run Docker containers in testing scenarios. In this article, we'll be looking at a community port of Testcontainers for Node.js (testcontainers-node), and how we can run tests that rely on both a single Redis and a Redis Cluster.

  • GitHub repo mockttp

    Powerful friendly HTTP mock server & proxy

    Project mention: AWESOME WINDOWS TOOLS | dev.to | 2021-04-26
