What are test cases in C programming

by Andreas Spillner and Ulrich Breymann, 246 pages, dpunkt Verlag, ISBN: 978-3-86490-308-3.

You program - also in C ++. You carry out unit tests on a regular basis. Sometimes you are unsure whether you have tested enough or too much. Take a look at this book, you will find lots of ideas for your daily work!

Does the following situation sound familiar to you? The user story (the feature, the class, the requirement detail) is programmed and ready to be checked in for the continuous integration process. I thought everything through carefully and programmed it properly, but before I check in the code, I will test my system part. It would be too annoying if there were later mistakes whose cause lies in my part; doesn't have to be! So let's start testing. But how and with what do I start and when have I tested enough?

This is exactly what the book gives you hints for! It answers the questions: How do I create test cases? Which criteria help, from when can a test be considered sufficient and thus ended? We believe that every developer also tests, at least his own program code, as described above. And if the developer receives practical advice in his familiar programming language, here C ++, we hope that it will help him in his daily work. The application of the test procedure leads to an improvement in the test procedure and the developer is provided with criteria as to when the test can be regarded as sufficient.

Lean testing stands for a test approach which, on the one hand, takes into account all the important test cases for testing the software, but on the other hand keeps the test effort within a manageable framework. The appropriate balance between too little and too much testing is discussed and debated in any test case design process.

The test case design procedures presented in this book are specifically presented with the corresponding C ++ program texts and the respective test cases. If supporting tools are required when designing the test cases, their application is described. The authors provide useful information on the use of the test procedures and guidelines for their use.
