utils VS cypress-realworld-app

I didn't use any inline asm, instead I wrote the simplest if statement possible, which I confirmed on x86_64, x86, and aarch64 compiles down to use the platform's supported conditional move instructions. If this changes in the future and there's a need to write inline asm, you can do so in a portable way, e.g. the cmov crate.

There's also cpufeatures which might suit your use case better (depending on exactly how you want to do it).

I have seen that RustCrypto also offers a create for securely zeroing memory with: zeroize

The zeroing routine itself looks fine to me. You might want to compare your code with the (already mentioned) zeroize crate, which does something similar (or maybe identical?).

To save a few clicks, this was found to be, indeed, a Y2K issue, and der v0.4.1 has just been released to fix it. Citing the comment added to the issue after the fact:

I opened a tracking issue for that.

Cypress documentation

The full source code of the examples shown in this article can be found here. The example web app is based on the react-note-taking-app built on top of the T3 Stack. The Cypress tests and configuration are based on the best practices documented in the cypress-realworld-app.

I’d encourage you to look at https://docs.cypress.io

Cypress is a modern, automated testing suite. It's a fully open source testing framework based on JavaScript and is built with libraries like Mocha and Chai that support BDD and TDD assertion styles. Further, using Cypress will be easy if you’re familiar with writing tests in JavaScript.

It's mainly about showing Cypress (which is something like Selenium or Playwright or what have you) but integrates it into a real world example with commonly used tools and frameworks.

I think the Cypress documentation is absolutely great:

https://docs.cypress.io/

One of the better things about cypress are how they create so many how-to guides for a variety of scenarios. Take implementing Cypress into a CI runners, they have guides on how to effectively use it nearly everywhere:

In addition, we have also prepared over 30+ examples of real-world tests against the Real World App. This application has been around for a couple of years now, but since it contains some rather advanced concepts and examples, much of it was beyond reach for people just getting started. To solve this problem we have written in-depth articles for every example which explains line by line what each test is doing.

Cypress.io is just a test runner, but it can be paired with Testomat.io, a test management system for automated tests. Let's see how Testomat.io can answer the questions risen above. We will use Cypress Realworld App as you might have guessed, this is a good example of a project with well-written Cypress tests.
