Beginning with test-driven Julia development

Test-driven development is a software development practice based on a simple workflow that puts automated testing center stage. The basic idea is that the requirements are turned into very specific, well-defined, and targeted test cases. Each test should address only one piece of functionality. Once the test is ready, we run the whole test suite. Obviously, as we first write the test, it will initially fail. Next, we add the minimal implementation to make the test pass. That's it—all we need to do is repeat the same process until all the requirements are implemented. This approach ensures that our code base is thoroughly tested and that we focus on delivering just the requirements, avoiding feature ...
