Testing modern Symfony apps

Introduction

The words "modern" and "PHP framework" would usually be considered oxymorons – and for good reasons. However, here is no point in denying that a large number of things on the internet relies on Symfony or some other PHP framework to run. These things will be gradually phased out or upgraded but for now they can't just remain untested because they're somewhat (out)dated...

API testing

The more rigorous part is RESTful API testing that relies on sending json to server and getting server back from the server. Let's create a boilerplate class that's going to help us send POST/GET/DELETE requests wrapped around as methods:


And now we're going to use that ancestor class to facilitate some real-life testing of user profile reads and updates.

To run the tests do the following

Frontend functional/flow testing

While valuable, the API testing will not cover certain aspects of the application flow. For example you changed some <script> dependency version loaded from a CDN. Your API works fine but for whatever reason your JS code will die (this happened to us with react-bootstrap which deprecated the ModalTrigger component at some point).

Here is a simple test in mocha.js and zombie.js that will attempt to log the user in and see if the content pages even load. No interaction, just "does it load?".

Then to run the test

React.js – edit and delete comments in CommentBox

It appears customary for high-intelligence, high-skills groups of engineers to "roll their own" whenever they have a chance to. Counter-intuitively to most managerial/MBA types out there, re-inventing the wheel can give you... a better wheel. Success is not guaranteed though – but these people may leave sooner rather than later if you don't let them... Having looked at number of JS frameworks (ember, backbone, angular) there was no clear winner. They were all a mess, at least to me. So I approached React.js with no hopes – how much better could it possible be? It turns out, a lot! This post will be an extension of the official React.js tutorial . The tutorial stops at the stage where you can add comments to a dynamic lists, that will grow as you add comments. This falls short of the functionality displayed on facebook: once you add a comment you can edit or delete it, so that's what're going to do. Full disclosure, I only started using React this weekendo so m

Example slurm cluster on your laptop (multiple VMs via vagrant)

To anybody who's considering a switch to modern queuing systems, like slurm, this will be an useful guide. Rather than doing a roll out on production nodes, we'll try things out in vagrant. This text assumes you have vagrant installed on your local machine (it's very easy). The ultimate aim will be to setup 2 servers (worker nodes) and one master/controller, and run a simple job on them. There are multiple great guides out there: most of them are out of date, and won't work without some tweaking on Ubuntu 16.04 Xenial. The entirety of the code is hosted at https://github.com/jandom/gromacs-slurm-openmpi-vagrant The README.md file will show you how to set it up, with checks on every step.

Wrapping openbabel in python - using cython

The previous post showed a contrived example of how one could access the openbabel functionality in python using the boost libraries. There is alternative to boost to wrap around c/c++ code, it's called cython. Here is an example openbabel wrapper, exposing some very simple functionality. Just before diving in, you should know that there already exists a wrapper around openbabel in python (it is called pybel). What I'm showing here doesn't even come close to pybel in terms of usefulness, the idea here is to show a demo of how easy wrapping things in python is. #! /usr/bin/python from ez_setup import use_setuptools use_setuptools() from setuptools import setup, Extension, find_packages from Cython.Distutils import build_ext import sys, os import glob import subprocess as sub def get_include(name="openbabel"): p = sub.Popen('locate %s' % name ,stdout=sub.PIPE,stderr=sub.PIPE, shell=True) output, errors = p.communicate()
