Flutter

Posted on 11/10/2017 by Sorin Dolha

I recently found out about the new cross-platform framework for mobile development that Google backs up: Flutter. Although it’s only in alpha stage (i.e. early development) at this time, I wonder, could it eventually reach more adopters than Xamarin or … Continue reading →

Avoid extracting internal libraries

Posted on 10/08/2017 by Sorin Dolha

In a not-too-small software development company it’s very likely that you’ll manage multiple projects over time, with multiple teams and doing work for multiple customers.

Can we skip unit tests for infrastructural code?

Mocking Entity Framework to unit test your data services

Posted on 08/11/2017 by Sorin Dolha

It’s not easy to write unit tests for services that use DbContext and DbSet<T> classes from Entity Framework (or Entity Framework Core), and there are complex solutions to approach this, like separating the data access layer completely, as I propose in my UnitOfWork-EntityFramework implementation. … Continue reading →

Stop over-abstracting

Posted on 08/10/2017 by Sorin Dolha

Developers are very good when it comes to abstracting things, be this: 1) generating base or generic classes to inherit from or reuse; 2) generic or overloaded functions called with arguments instead of standalone ones; or 3) reusing code under multiple technologies even if it’s … Continue reading →

Bridging

Architect vs. developer

Posted on 11/22/2016 by Sorin Dolha

A software developer knows how to (and will be eager to) generalize things – for example using a list instead of a single item or a generic type or method instead of a specific one – enabling more scenarios with supposedly minimal amount of initial … Continue reading →

Too much dependency injection?

Posted on 07/11/2016 by Sorin Dolha

I’m sure you use dependency injection in many of your projects. And usually, it’s a very good thing to do. However, I found out that many people use it somehow blindly: every time they need to extract a new class just … Continue reading →
