Unit tests exercise various paths through your codebase. Some are happy paths where everything you expect goes right. These tests are boring. The interesting tests are the ones where your code goes hurtling off the happy path. The trick is to capture the diversity of a multitude of unhappy paths without needlessly duplicating unit tests. Here's how you can improve the quality of your unit testing and fix it more effectively.

Writing changeable code makes it easier and more cost-effective to add features to existing software. Writing changeable code doesn’t take longer, but it does require paying attention to certain things when building a system. It's important to have a good suite of unit tests that support refactoring code when needed, and test-driven development helps you create independently testable code.

AngularJS is a framework used for organization of JavaScript code in highly interactive web and mobile applications. What does that mean from a testing perspective? Here's what should be in your test strategy when you’re testing Angular applications, including what might give you difficulty and how you can mitigate challenges.

In automated testing, one of the challenges to developing consistent and stable tests is loading and rendering time and latencies. This plays a larger role for web applications or other network dependent applications, especially with user interface automation. But you can design tests so that timeouts can be used to measure the performance of the application and service while testing the functionality.
