Coded UI vs White

Today, we’ll look at Coded UI and White automation frameworks in terms of building an automated UI test suite for a WPF application. We are going to compare them from different points of view, such as performance, the ease of getting started and maintainability. You will see which of these two frameworks suits what kind of projects and how to make a decision in your particular circumstances.

Fail Fast principle

The fail fast principle is underlying for many other software development practices. It comes out so often that it’s hard to cover all its appearances in a single article. Nevertheless, that is exactly what I’m going to do here :)

DRY revisited

Another principle we should follow when building a software project is the DRY principle. The abbreviation stands for Don’t Repeat Yourself. While it seems pretty straightforward and intuitive, this principle is more than meets the eye. Let’s see how it is so.

Cohesion and Coupling: the difference

This is another post on the most valuable principles in software development.

You might have heard of a guideline saying that we should aim to achieve low coupling and high cohesion when working on a code base. In this article, I’d like to discuss what this guideline actually means and take a look at some code samples illustrating it. I also want to draw a line between these two ideas and show the differences in them.

State vs migration-driven database delivery

The topic described in this article is a part of my Database Delivery Best Practices Pluralsight course

In the previous post, I wrote about the database versioning best practices. I’ve got a lot of feedback on that topic. One of the responses stated that the article was (admittedly) one-sided as it didn’t cover the other widely spread approach to managing the database delivery process. I decided to fill that gap and provide my own comparison of the two. This article is about the state versus migration-driven database delivery.

Database versioning best practices

The topic described in this article is a part of my Database Delivery Best Practices Pluralsight course.

Keeping track of your application’s database is not an easy task. Database schemas tend to mismatch in different environments, data in one of the databases may miss some crucial piece of data. Such occasions can be irritating, especially when caught in production.

The situation gets worse when you develop redistributable software. In this case, each of your clients has their own database instance whose structure may differ from others’. In such a project, keeping track of your clients’ databases can become a nightmare.

Let’s look at the database versioning best practices that help us deal with this problem.
