PHPT VS Codeception

In our latest story we show a couple of smart ways to get around some import conflicts in PHP.

The values [0, 15] represent 16 possible values, which is a power of 2.

The correct way to get an unbiased distribution from a sample of 2^x to a modulo that is not an even power of 2 is to use rejection sampling.

This is what RFC 6979 says to do https://datatracker.ietf.org/doc/html/rfc6979#section-3.2

But you can also see this technique in CSPRNG code; i.e. https://github.com/php/php-src/blob/d40726670fd2915dcd807673...

I am running this code on MacOS on Apple Silicon hardware which is crashing when using the JIT in a ZTS build of PHP, so the 1m 35s result is without JIT, it might be even faster if I could use it

A little about me; I'm a web developer and have been for around 5 years, though I'd dabbled for years. I have experience with Perl and PHP but my day to day is JavaScript/TypeScript be it through NodeJS or ReactJS. I want to learn Rust for no specific reason other than it's fun to learn new things.

Consider a web application where requests are handled through NGINX as the web server and PHP as the dynamic backend language. Let’s say something in the application logic results in a fatal error or process termination. This doesn’t affect NGINX’s ability to serve a response to the client, which would most likely be an HTTP 503 - Service Unavailable message.

In the beginning, I used a technology called CGI to develop server applications written in Perl. This technology was later replaced by Microsoft’s ASP (Active Server Pages) and then PHP. PHP, which you may already know, is still powering over 77% of all the websites as of the time of writing (ever heard of WordPress?).

PHP

As Shopware is mostly based on the Symfony framework, which is in turn based on the PHP language, we should also consider learning about the basics, which will also be useful for other frameworks apart from Shopware, like Symfonycasts, symfony.com, php.net.

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

Codeception: https://codeception.com/

I would say to check out Codeception. Codeceptions has modules for Symfony and database generally. Long and short of it is that if you want you can run api tests that go into the controllers and rollback the database afterwards.

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.

This is a quote from this year's new Testify T-Shirt, my physical takeway from this event. While I don't agree that we should automate everything we can, I still chose this design as it shows Codeception code.

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.”
