Codeception VS stylelint

Personal experience: - don’t use Behat unless you really needed a “story telling”, it has a intermediate layer Gherkin that you’ll need to code. You can write “Given/When/Then” steps but you’ll also need to write “php code” that will interpret this step. - using real browser be prepared for instability - any interaction with JavaScript can broken/delay execution - be prepared that this tests are call functional they are the most expensive test, so start small unit then integration and only then functional. - use https://github.com/symfony/panther or https://codeception.com/ you’ll have phpunit alike interface to run them. - you’ll need to reset state of your database each time to provide “isolation” and stability

There are enough blog posts about Jest or Cypress already, so let me introduce Codecept. It comes in two flavors. There is Codeception for PHP, and there is CodeceptJS for JavaScript which we will be using here.

There are many tools you can use for this purpose, but one I particularly like is CodeCeption. What I like most about it is that it's a unified tool that can be used to perform several types of tests, acceptance being one of them.

And within the Symfony ecosystem Codeception, which “collects and shares best practices and solutions for testing PHP web applications. With a flexible set of included modules tests are easy to write, easy to use, and easy to maintain.”

Other tools worth mentioning include Codeception and behat. Both use phpUnit underneath, but have different approaches to writing tests.

Another common way to extend configs in linters is using the extends key in the configuration file. Let's take StyleLint as an example:

Stylelint is similar to ESLint, but its focus is on styling rather than JavaScript. It helps you find errors in style files, such as old syntax or empty classes. We will also incorporate stylelint-config-clean-order to sort your style rules and group them consistently across the entire codebase.

The “cost of loading modules” diagram shows non-linear behaviour (though you should largely ignore the curve visible in the diagram because the x axis is way off linear):

• 0.15s ÷ 500 = 0.3ms

• 0.31s ÷ 1000 = 0.31ms

• 3.12s ÷ 10000 = 0.312ms

• 16.81s ÷ 25000 = 0.6724ms

• 48.44s ÷ 50000 = 0.9688ms

My own observation on a Surface Book six years ago was that in Node.js under Windows, each module had about 1ms of overhead when there was warm file system cache—that is, simply bundling with Rollup saved 1ms per file. If this sort of thing interests you, quite a lot of useful stuff came out of https://github.com/stylelint/stylelint/issues/2454 which I filed because I was unhappy with stylelint taking over a second to import. And that must have been only in the order of one or two thousand modules, when the behaviour is still close enough to linear.

Document your build process in a blog, use eslint, stylelint and jsx-a11y lint. Run a lighthouse performance test, follow the optimisation reccomendations.

Run static analysis e.g. lint with lockfile-lint, Stylelint, ESLint, check for unimported files using unimported, and identify potential security vulnerabilities

The complete code for this project is in the Rodney Lab GitHub repo. I do hope the post has either helped you with an existing project or provided some inspiration for a new one. As an extension, you can add all your favourite future CSS rules to the PostCSS config. Beyond PostCSS for linting your input CSS, consider trying stylelint.

Stylelint helps prevent errors and ensures style conventions.

After installation, it will generate a lefthook.yml file which can be customized to perform a static code analysis before committing the code. For example, it can ensure that the git commit follows the git-conventional-commits, and use Prettier, ESLint, and Stylelint to check, format, and fix any file which will be committed and run any test related with Vitest depending on the filetype and run each in parallel.

We might also call stylelint so we can lint our source CSS.
