Hands-On Software Engineering with Python

By: Brian Allbee, Nimesh Verma

Overview of this book

Software Engineering is about more than just writing code—it includes a host of soft skills that apply to almost any development effort, no matter what the language, development methodology, or scope of the project. Being a senior developer all but requires awareness of how those skills, along with their expected technical counterparts, mesh together through a project's life cycle. This book walks you through that discovery by going over the entire life cycle of a multi-tier system and its related software projects. You'll see what happens before any development takes place, and what impact the decisions and designs made at each step have on the development process. The development of the entire project, over the course of several iterations based on real-world Agile iterations, will be executed, sometimes starting from nothing, in one of the fastest growing languages in the world—Python. Application of practices in Python will be laid out, along with a number of Python-specific capabilities that are often overlooked. Finally, the book will implement a high-performance computing solution, from first principles through complete foundation.

Programming versus Software Engineering

The overall testing strategy

Before writing the code that implements the full process testing, an effort needs to be made to complete and successfully execute all of the outstanding unit tests. Once this is complete, we can logically take it as a given that any failures that arise in the process tests are because of something in that process, though we may want to take steps to verify sub-process steps, and raise failures for certain conditions. This may well evolve as the process tests are written.

Each business object that has a set of corresponding processes needs to check for any/all of the following processes that apply:

  • Creation of the object, and both local and remote persistence of its data:
    • By each role that is allowed to perform an update
    • Making sure to test both valid and invalid update attempts
  • Updating the object's data:
    • By each role that is allowed...
