Overview of this book

Learning how to code has many advantages, and gaining the right programming skills can have a massive impact on what you can do with your current skill set and the way you advance in your career. This book will be your guide to learning computer programming easily, helping you overcome the difficulties in understanding the major constructs in any mainstream programming language. Computer Programming for Absolute Beginners starts by taking you through the building blocks of any programming language with thorough explanations and relevant examples in pseudocode. You'll understand the relationship between computer programs and programming languages and how code is executed on the computer. The book then focuses on the different types of applications that you can create with your programming knowledge. You'll delve into programming constructs, learning all about statements, operators, variables, and data types. As you advance, you'll see how to control the flow of your programs using control structures and reuse your code using functions. Finally, you'll explore best practices that will help you write code like a pro. By the end of this book, you'll be prepared to learn any programming language and take control of your career by adding coding to your skill set.

Integration testing

Integration testing is about putting several units together and testing them so that they work correctly when they are no longer isolated, but work together.

Units that work together will need to communicate, and they will communicate by passing data between them. This means that integration testing is about checking that the data transfer and data representation aspects work.

Imagine that we are working on a project that is divided into several modules. To speed up development time, we let several programmers work on the separate modules. This might look something like this:

Figure 11.6 – Four developers working on four different modules

Figure 11.6 – Four developers working on four different modules

These four developers will now start to write their modules, and they will make sure that their modules meet the requirements by running unit tests on them. But the only thing these tests will show is that this module works in isolation.

But in the final application, these modules...
