Learn Go with Tests
Learn Go with test-driven development
Katas are fun but they are usually limited in their scope for learning a language; you're unlikely to use goroutines to solve a kata. Another problem is when you have varying levels of enthusiasm. Some people just learn way more of the language than others and when demonstrating what they have done end up confusing people with features the others are not familiar with. This ends up making the learning feel quite unstructured and ad hoc. By far the most effective way was by slowly introducing the fundamentals of the language by reading through go by example, exploring them with examples and discussing them as a group. This was a more interactive approach than "read chapter x for homework". Over time the team gained a solid foundation of the grammar of the language so we could then start to build systems. This is for people who are interested in picking up Go and/or people who already know some Go, but want to explore testing more. -

Mocha
A feature-rich JavaScript test framework running on Node.js
Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases. Hosted on GitHub. Mocha runs in the browser. Every release of Mocha will have new builds of ./mocha.js and ./mocha.css for use in the browser. Mocha is the most-depended-upon module on npm and Mocha is an independent open-source project, maintained exclusively by volunteers. Given Mocha’s use of function expressions to define suites and test cases, it’s straightforward to generate your tests dynamically. No special syntax is required — plain ol’ JavaScript can be used to achieve functionality similar to “parameterized” tests, which you may have seen in other frameworks. -

Passmark
The open-source Playwright library for AI browser regression testing
The Passmark project is an open-source AI-powered regression testing framework built on top of Playwright that enables developers to write end-to-end browser tests using natural language instead of traditional scripting. It is designed to simplify and accelerate testing workflows by allowing AI models to interpret human-readable instructions and translate them into executable browser actions. One of its defining features is a cache-first execution model, where AI is used initially to discover how to perform actions, and those actions are then stored and replayed at native speed in future runs. This approach significantly reduces reliance on AI during repeated test executions, improving both performance and cost efficiency. The framework also incorporates multi-model validation, using multiple AI systems to verify assertions and reduce the risk of incorrect results. -

Specification
Base class with tests for adding specifications to a DDD model
Specification is a .NET library that implements the Specification pattern to encapsulate query logic into reusable, composable objects. Its primary goal is to pull filtering, sorting, and projection logic out of repositories and services, reducing duplication and improving maintainability. The library works especially well with Entity Framework Core, enabling developers to centralize query definitions instead of scattering LINQ expressions throughout the codebase. By defining specifications as classes, teams can build complex query rules that remain testable and easy to reason about. The project is used in Microsoft’s reference application eShopOnWeb and aligns closely with clean architecture principles. Overall, Specification provides a structured approach to query reuse and domain-focused data access in modern .NET applications. -

Testimo
Testimo is a PowerShell module for running health checks for AD
Testimo is a PowerShell-based test automation framework that simplifies writing, running, and reporting tests for infrastructure and script libraries. It provides constructs to define test cases, assertions, setup/teardown sequences, and grouping so validation logic is clear and maintainable. Designed for operations and platform engineers, Testimo focuses on verifying infrastructure state (configuration settings, service availability, registry keys) rather than purely unit-level code, making it useful for smoke tests, image validations, and deployment gates. Test runs can emit structured reports, integrate with CI systems, and be scheduled as part of regular compliance checks to ensure environments remain in expected states. Because it’s built on PowerShell, Testimo reuses native cmdlets and objects directly in assertions, reducing the impedance mismatch between tests and target systems. -

gomock
GoMock is a mocking framework for the Go programming language
gomock is a mocking framework for the Go programming language. It integrates well with Go's built-in testing package, but can be used in other contexts too. Once you have installed Go, install the mockgen tool. If you have not done so already be sure to add $GOPATH/bin to your PATH. If you use mockgen in your CI pipeline, it may be more appropriate to fixate on a specific mockgen version. Source mode generates mock interfaces from a source file. It is enabled by using the -source flag. Other flags that may be useful in this mode are -imports and -aux_files. Reflect mode generates mock interfaces by building a program that uses reflection to understand interfaces. It is enabled by passing two non-flag arguments, an import path, and a comma-separated list of symbols. The mockgen command is used to generate source code for a mock class given a Go source file containing interfaces to be mocked. -

pipx
Install and run Python applications in isolated environments
pipx is a tool to help you install and run end-user applications written in Python. It's roughly similar to macOS's brew, JavaScript's npx, and Linux's apt. It's closely related to pip. In fact, it uses pip, but is focused on installing and managing Python packages that can be run from the command line directly as applications. pip is a general-purpose package installer for both libraries and apps with no environment isolation. pipx is made specifically for application installation, as it adds isolation yet still makes the apps available in your shell: pipx creates an isolated environment for each application and its associated packages. pipx does not ship with pip, but installing it is often an important part of bootstrapping your system. By default, pipx uses the same package index as pip, PyPI. pipx can also install from all other sources pip can, such as a local directory, wheel, git url, etc. -

redux-saga
An alternative side effect model library for Redux applications
redux-saga is a library that aims to make application side effects (i.e. asynchronous things like data fetching and impure things like accessing the browser cache) easier to manage, more efficient to execute, easy to test, and better at handling failures. The mental model is that a saga is like a separate thread in your application that's solely responsible for side effects. redux-saga is a redux middleware, which means this thread can be started, paused and cancelled from the main application with normal redux actions, it has access to the full redux application state and it can dispatch redux actions as well. It uses an ES6 feature called Generators to make those asynchronous flows easy to read, write and test. (if you're not familiar with them here are some introductory links) By doing so, these asynchronous flows look like your standard synchronous JavaScript code. (kind of like async/await, but generators have a few more awesome features we need). -

speedtest-cli
Command line interface for testing internet bandwidth using speedtest
Command line interface for testing internet bandwidth using speedtest.net. It is not a goal of this application to be a reliable latency reporting tool. Latency reported by this tool should not be relied on as a value indicative of ICMP style latency. It is a relative value used for determining the lowest latency server for performing the actual speed test against. Speedtest CLI brings the trusted technology and global server network behind Speedtest to the command line. Measure internet connection performance metrics like download, upload, latency and packet loss natively without relying on a web browser. Test the internet connection of your Linux desktop, a remote server or even lower-powered devices such as the Raspberry Pi with the Speedtest Server Network. Set up automated scripts to collect connection performance data, including trends over time. -

vcr
Record your test suite's HTTP interactions and replay them
Record your test suite's HTTP interactions and replay them during future test runs for fast, deterministic, accurate tests. We're looking for more maintainers. If you'd like to help maintain a well-used gem please spend some time reviewing pull requests, issues, or participating in discussions. VCR will replay the response from iana.org when the HTTP request is made. This test is now fast (no real HTTP requests are made anymore), deterministic (the test will continue to pass, even if you are offline, or iana.org goes down for maintenance) and accurate (the response will contain the same headers and body you get from a real request). You can use a different cassette library directory (e.g., "test/vcr_cassettes"). The recorded requests and responses are stored on disk in a serialization format of your choice (currently YAML and JSON are built in, and you can easily implement your own custom serializer) and can easily be inspected and edited. -
