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

Unit testing patterns established so far

There's been a lot of exploration of the unit testing of the first module in the system, and that exploration has established some patterns that will appear frequently in unit testing of the other system code as it is written, so they will not be re-examined in any significant detail from this point on unless there's a significant new aspect to them.

Those patterns are as follows:

  • Iteration over good and bad value lists that are meaningful as values for the member being tested:
    • Standard optional text line values
    • Standard required text line values
    • Boolean (and numeric equivalent) values
    • Metadata values
    • Non-negative numeric values (for weight values, in this case)
  • Verifying property method associations—getter methods in every case so far, and setter and deleter methods where they are...
