What your test suite won't catch

Test suites are one of the tools we have to improve the quality of software while we're building it; they are particularly fitting for checking functional requirements and some other properties such as performance and some forms of maintainability. However, there are other critical properties that may be important in your project and that your test suite cannot help you in fixing. However, we still can put in place processes that give us feedback on the matter, such as security audits, code review and pair programming for maintainability, and higher-level models than code for concurrency issues. Tests are a tool, not an end.

A quick recap of the problem: implement binary search, a classic algorithm, over a sorted array (or your preferred random-access linear data structure, depending on your programming language.) You should compare different programming styles and paradigms if you can, with the goal of stimulating your creativity to find 5 different ways to implement the algorithm.

Writing Tests Against Page Objects

When you write tests against a web page, you need to refer to elements within that web page in order to click links and determine what's displayed. However, if you write tests that manipulate the HTML elements directly, your tests will be brittle when there are changes in the UI.

How a LazyDecorator can let your application avoid building massive object graphs

Wiring code is a great way to document your designs, as it's always in sync with the rest of the code while diagrams aren't. However, it's important to consider all non-functional concerns of your Factories: how readable they are, but also how efficient they are in creating objects to satisfy the most common use case in your application.
