Installing PHPUnit+PEAR in Ubuntu 12.10 and Overcoming the "PHP_CodeCoverage_Filter::getInstance" Fatal Error

PHP was one of the very first languages I learnt on my way to the world of web dev/design and it still is a very strong tool in my Swiss Army Knife for any web based projects.

In recent times however with the advent of various frameworks I started to realize finally my days of painstaking coding is over and I now can finally work on my small-medium sized applications with minimal effort needed for testing.......how wrong I was.

When introduced to the world of testing I started to realize how inefficient and poor my coding standards were also how terrible they were in terms of maintenance. Also the flaws I started to find in my old projects urged me to unit-test my newer ventures. And I found the gem called PHPUnit

There are three ways of installing it in your dev box (Assuming Ubuntu)

  • Install Through PEAR
  • Install Through Composer
  • Install using standalone PHAR file
And as a loyal user of PEAR I straight went to PEAR and just typed the following command which is supposed to install PHPUnit in one go

$ sudo pear install phpunit/PHPUnit
Satisfied with the result I went to the terminal again and ran > phpunit
But to my surprise I got

 PHP Fatal error: Call to undefined method PHP_CodeCoverage_Filter::getInstance() in /usr/bin/phpunit on line 39

 Bewildered I ran to find what was causing it, but couldn't find any definite solution. So I again fired up my dev virtual box with ubuntu 12.04 and there it was running fine.

 Suspecting something was wrong with my PEAR package I went ahead and  typed
$ pear config-show

 It showed me (unlike the config on my 12.10)

 Configuration (channel pear.php.net):
=====================================
Auto-discover new Channels auto_discover

Package Signature Type sig_type gpg
PEAR username (for username 
maintainers)
User Configuration File Filename /home/username/.pearrc
System Configuration File Filename /etc/pear/pear.conf

 Getting sniff of what was wrong I fixed my environments using the following commands
sudo pear config-set bin_dir /usr/binsudo pear config-set doc_dir /usr/share/php/docsudo pear config-set php_dir /usr/share/phpsudo pear config-set cfg_dir /usr/share/php/cfg (make (sudo mkdir cfg) directory here)sudo pear config-set data_dir /usr/share/php/data
sudi pear config-set test_dir /usr/share/php/test
And then the following
$ sudo pear uninstall phpunit/PHPUnit
$ sudo pear install phpunit/PHPUnit
And after that it ran like a charm.

 Note:  This happened quite a while ago. I finally got urge to post it because on of my friends faced the exact same problem last night and she couldn't find any solution. When she was telling me today I just figured out just by hearing the error what might be wrong. And the above fixed her issue.

 And it dawned to me maybe If I had posted this earlier it could have helped her :P

    sudo apt-get install phpunit

    That installs it and takes care of any dependencies automatically. Also sets things in the correct path.

    No need to over-complicate things.

Curious case of Cisco AnyConnect and WSL2

One thing Covid has taught me is the importance of VPN. Also one other thing COVID has taught me while I work from home  is that your Windows Machine can be brilliant  as long as you have WSL2 configured in it. So imagine my dismay when I realized I cannot access my University resources while being inside the University provided VPN client. Both of the institutions I have affiliation with, requires me to use VPN software which messes up WSL2 configuration (which of course I realized at 1:30 AM). Don't get me wrong, I have faced this multiple times last two years (when I was stuck in India), and mostly I have been lazy and bypassed the actual problem by side-stepping with my not-so-noble  alternatives, which mostly include one of the following: Connect to a physical machine exposed to the internet and do an ssh tunnel from there (not so reliable since this is my actual box sitting at lab desk, also not secure enough) Create a poor man's socks proxy in that same box to have...

Deep Dive into the Google Agent Development Kit (ADK): Features and Code Examples

In our previous overview, we introduced the Google Agent Development Kit (ADK) as a powerful Python framework for building sophisticated AI agents. Now, let's dive deeper into some of the specific features that make ADK a compelling choice for developers looking to create agents that can reason, plan, use tools, and interact effectively with the world. 1. The Core: Configuring the `LlmAgent` The heart of most ADK applications is the LlmAgent (aliased as Agent for convenience). This agent uses a Large Language Model (LLM) for its core reasoning and decision-making. Configuring it effectively is key: name (str): A unique identifier for your agent within the application. model (str | BaseLlm): Specify the LLM to use. You can provide a model name string (like 'gemini-1.5-flash') or an instance of a model class (e.g., Gemini() ). ADK resolves string names using its registry. instruction (str | Callable): This is crucial for guiding the agent's be...

Build Smarter AI Agents Faster: Introducing the Google Agent Development Kit (ADK)

The world is buzzing about AI agents – intelligent entities that can understand goals, make plans, use tools, and interact with the world to get things done. But building truly capable agents that go beyond simple chatbots can be complex. You need to handle Large Language Model (LLM) interactions, manage conversation state, give the agent access to tools (like APIs or code execution), orchestrate complex workflows, and much more. Introducing the Google Agent Development Kit (ADK) , a comprehensive Python framework from Google designed to significantly simplify the process of building, testing, deploying, and managing sophisticated AI agents. Whether you're building a customer service assistant that interacts with your internal APIs, a research agent that can browse the web and summarize findings, or a home automation hub, ADK provides the building blocks you need. Core Concepts: What Makes ADK Tick? ADK is built around several key concepts that make agent development more s...
