The Problem: Isolated Testing and Documentation Challenges

Developers often encounter challenges when it comes to testing and documentation in a cloud-based environment. Isolated testing of cloud functions, especially when they depend on external services like GCP APIs, and Data Sources in production, can be complex and time-consuming. Additionally, maintaining consistent documentation can become a tedious task

The Solution: Custom Cloud Functions

To address these challenges, we propose the use of custom cloud functions in GCP. These functions are specially designed for testing purposes and contain setup and tear-down code, making isolated testing more efficient. Then the Testing can be moved to API testing with Postman. Additionally Postman is a good repository for documenting the API.

Benefits of Custom Cloud Functions:

  1. Isolated Testing: Custom cloud functions allow developers to test specific parts of their codebase in isolation. This reduces the risk of unintended side effects during testing.
  2. Enhanced Code Reusability: Developers can write functions within these custom cloud functions that are reusable across different parts of the application. This promotes cleaner and more maintainable code.
  3. Error Diagnosis: Custom cloud functions living alongside the code provide a valuable resource for diagnosing errors. Developers can tap into these test APIs to identify issues quickly, even when someone else modifies functions.

The Process

Here’s a step-by-step guide on how to implement this testing approach:

1. Create Custom Cloud Functions

  • Identify areas of your codebase that require testing isolation.
  • Write custom cloud functions for these areas, focusing on setup, execution, and tear-down code.
  • Ensure that these functions are well-documented, providing clear instructions for other developers.

2. Integrate API Endpoints

  • To test your cloud functions, expose them as API endpoints using GCP services like Cloud Functions or App Engine.
  • Ensure that the API endpoints are secure and follow best practices for authentication and authorization.

3. Testing in Postman

  • Use Postman to create test collections that interact with your API endpoints.
  • Write test scripts in Postman to automate testing scenarios.
  • Postman’s testing platform allows you to run a wide range of tests, from simple unit tests to complex integration tests.

4. Documentation in Postman

  • Leverage Postman’s documentation feature to create detailed documentation for your API endpoints.
  • Postman generates documentation automatically, making it easy for developers to understand how to interact with your API.

5. Continuous Integration

  • Integrate your custom cloud functions, API endpoints, and Postman tests into your CI/CD pipeline (Newman helps).
  • Automate the testing process to ensure that tests are run consistently with each code change.


Implementing this testing approach offers several advantages:

  • Efficiency: Custom cloud functions make testing more efficient, saving time and effort for developers.
  • Code Quality: Improved code reusability leads to cleaner and more maintainable code.
  • Documentation: Postman’s documentation feature ensures that your API is well-documented and accessible to all team members.
  • Error Diagnosis: Easy access to test APIs simplifies error diagnosis and troubleshooting.


  • Postman gets expensive as you collaborate with more people. Other tools allow you to import Postman collections and are cheaper.


Incorporating custom cloud functions, API endpoints, and Postman into your GCP development workflow can significantly enhance your testing process and documentation efforts. By isolating testing, promoting code reusability, and leveraging Postman’s powerful testing and documentation capabilities, your Python development team can streamline their development workflow and produce more reliable and well-documented applications in the cloud.

Applying the Laws of Physics to Software Development: A Fascinating Connection

Software development, at first glance, may seem like an entirely different realm from the laws of physics. After all, it’s about lines of code and digital interfaces, while physics deals with the natural world. However, upon closer inspection, one can find intriguing parallels between the two seemingly disparate fields. In this article, we will explore how certain laws of physics can be applied to software development and shed light on how they can help us better understand the dynamics of this ever-evolving industry.

Disclaimer: This article was written by ChatGPT based on some ideas that I had while thinking about the parallels between software development and the laws of physics, and chaos theory. I am amazed at how well that ChatGPT was able to capture and reflect my ideas as a coherent article.

  1. The Law of Stall Speed and Software Development:

Just as an airplane has a stall speed, which is the minimum speed at which it can maintain level flight, software development faces a similar challenge. The “stall speed” in software development can be seen as the point at which a project risks failure due to insufficient resources, unrealistic expectations, or misaligned strategies. When developers push too hard against market trends or operate with limited resources, they risk “stalling” their software development efforts. To avoid this, it is essential to maintain a balance and align development efforts with market demands and available resources.

  1. Reduced Engine Size and Code Efficiency:

In aviation, reducing engine size can improve fuel efficiency and performance. Similarly, in software development, reducing code size and complexity can lead to more efficient and maintainable software. Bloated codebases can slow down development, introduce bugs, and make it challenging to adapt to changing requirements. Therefore, software engineers must strive for code efficiency and simplicity to ensure smoother development and long-term viability.

  1. Angle of Attack and Adapting to Change:

The concept of the “angle of attack” in aviation refers to the angle between the wing’s chord line and the oncoming airflow. It is critical for controlling the aircraft’s lift and stability. In software development, the angle of attack can be equated to the adaptability of a project. Software projects that can adjust their “angle of attack” by quickly responding to changing market conditions or user feedback are more likely to succeed. Staying agile and open to adjustments is essential to navigate the ever-evolving landscape of software development successfully.

  1. Entropy and Software Evolution:

Entropy is a fundamental concept in physics that describes the tendency of systems to move towards greater disorder or chaos unless energy is applied to maintain order. In software development, we observe a similar phenomenon. As software evolves and grows, without continuous maintenance and refactoring, it tends to become more chaotic and less efficient. This accumulation of “software entropy” can slow down development and increase the risk of software failure. To combat this, developers must invest in ongoing maintenance, updates, and optimization to keep their software in a state of order and efficiency.

  1. Metabolism and Software Development Velocity:

Metabolism in the natural universe can be likened to the “velocity” of software development. Just as organisms with higher metabolism tend to have shorter lifespans, software projects with rapid development cycles may have shorter lifespans too. While a high development velocity can be advantageous for quickly delivering features and updates, it must be balanced with quality assurance and sustainability to ensure the longevity of the software.


The application of laws of physics to software development may seem like an unconventional comparison, but it provides valuable insights into the dynamics of this industry. By recognizing the parallels between stall speed, reduced engine size, angle of attack, entropy, and metabolism in both fields, software developers can make more informed decisions, improve code quality, and increase the chances of long-term software success. Embracing these principles can help the software development community navigate the ever-changing landscape of technology with greater efficiency and effectiveness.
