Modern unit testing in C with TDD and Ceedling - Embedded.com.
They have their pros and cons, their detractors and supporters. But every one of them is better, by far, than continuing not to write unit tests. You can always re-evaluate and switch later if you need to. I’ve used a lot of different unit test frameworks in my career and never felt locked in or concerned about it.
It can be difficult to write unit tests for code that accesses the file system. It’s possible to write integration tests that read in an actual file from the file system, do some processing, and check the resultant output file (or result) for correctness. There are a number of potential problems with these types of integration tests including the potential for them to more run slowly (real.
Assuming that I've correctly managed to extrapolate the SUT and friends from the question, I'd reduce the tests to the following. Please note that this focuses only on AutoFixture mechanics, and not on the general design of neither test nor SUT API. AFAICT, the following tests state the same as the tests in the OP, but reduced to only the necessary statements.
Write and implement good unit tests by Erica Henson in Software Engineer, in Developer on March 1, 2010, 10:50 PM PST Unit tests are a great way to make sure that your application works as intended.
Automated tests help you to catch bugs earlier in the software development lifecycle, right when you’re coding. These tests are repeatable. Write them once and run them over and over. The benefits of using unit tests are: help you to catch and fix bugs earlier, before releasing your app into production; help you to write better code with less.
If you write tests after writing the production code it is still possible to do so without changing too much of the code even with protected methods. If the code has been written using encapsulation there must be a reason for that and therefore the tests should not force you to break everything down.
Adopt Unit Testing to Pass All the Tests Unit testing is one of the practices that make Agile processes viable. These processes encourage collective code ownership to avoid writing components used by just a few developers. This improves the ability to nimbly react to high-priority change needs, but this agility comes at the risk of accidentally.
