xUnit VS ua-parser-js

Several well-known NuGet packages such as xUnit.net, FluentAssertions, StyleCop, Entity Framework Core, and others include by default a significant number of Roslyn analyzers. They help you adhere to the conventions and best practices of these libraries.

Most of my rules apply to document types, so let's build some tests for document types. We start by creating a new test class and a new test function and getting a list of all document types. This test is created using xUnit and FluentAssertions:

xUnit -> https://xunit.net/

.NET / xUnit / NUnit / MSTest

This library extends the traditional assertions provided by frameworks like MSTest, NUnit, or XUnit by offering a more extensive set of extension methods. Fluent Assertions supports a wide range of types like collections, strings, and objects and even allows for more advanced assertions like throwing exceptions.

You can verify the functionality of this validator by writing the following tests (using xUnit):

The git repo has other runners. AssemblyRunner appears to be the best fit for an already compiled tests project, but there is a runner that can be wrapped into an MSBuild task for example.

At this point you're going to see a familiar screen asking you to select a project. Here we're looking for a test project. By default, Visual Studio gives you access to 3 different testing frameworks based on your choice of project. These are MSTest, XUnit and NUnit. Ultimately, all 3 of these testing accomplish the same thing, and I've worked with all of them at various points in my career. The difference is mainly in exact syntax and documentation. Although, it's generally considered that MSTest is a little "older" than NUnit or XUnit, so I tend to see it less now. For the purposes of this demo, I'm going to go with NUnit:

xUnit unit tests tool

Use a testing framework: Utilize a testing framework like NUnit, xUnit, or MSTest to create, organize, and run your tests. These frameworks provide a consistent way to write tests, generate test reports, and integrate with continuous integration tools.

Just look at all the big companies doing it

With NPM, what's actually published is not what's in the git repo, so it's harder to inspect/review vulnerabilities or hijacking. With composer, what's in git _is_ what composer pulls (with the exception of rules in .gitattributes to exclude files etc), making it much easier to trace. One such example: https://github.com/faisalman/ua-parser-js/issues/536

Composer packages are vendor namespaced, so hijacking an abandoned package is not possible (and it is with NPM), some examples like https://www.theregister.com/2021/08/10/github_npm_package/

Sure, I suppose in theory it could happen with other ecosystems, but for some reason it doesn't. It sure seems to just keep happening in NPM though.

From the other side, npm package may be hijacked(as it happened recently for ua-parser-js and to other packages earlier). To mitigate that, I don't know, probably, subscribing to some security digest would be the most helpful.

On Oct. 22, 2021, developers of a very common NPM package, ua-parser-js, discovered that some attackers uploaded a compromised version of the package containing malware for Linux and Windows, and were capable of stealing data (at least passwords and cookies from the browser).

Since Neovim 0.5 release (which has full Lua support) I see more and more amazing Lua plugins being developed, and I think this trend will likely to continue. But I recently got more concerned about security risks associated with the way Neovim plugins being installed and used (especially after seeing recent compromises like ua-parser-js or coa). Installing typical Neovim plugin is basically downloading and executing random code from the internet on your machine with your user privileges, so hijacked or deliberately malicious plugin could potentially do a lot of damage (like stealing keys/passwords, installing keylogger or just rm -rf / for fun).
