Speeding up AutoFixture

I already mentioned about AutoFixture in one of the posts – Lightning talk – Autofixture. Main goal of this library is to help us with reduction of Arrange part of unit tests. With this library we can focus on the main scenario of unit test instead of focusing on building objects that are needed for test. Moreover AutoFixture will protect us against modification of classes that are being used in our unit tests. But it is not perfect. Sometimes duration of unit tests can increase dramatically. Especially when you are creating objects used by EntityFramework. […]

FluentValidation.Validators.UnitTestExtension

I would like to introduce a new small library that I published – FluentValidation.Validators.UnitTestExtension. Main purpose of this library is to extend and simplify possibilities of testing code that is using FluentValidation package. You can install it by nuget: Install-Package FluentValidation.Validators.UnitTestExtension or download it from GithHub. One of approach of testing Fluent rules is presented in FluentValidation wiki page. You can find there information that FluentValidation comes with two extension methods ShouldHaveValidationErrorFor and ShouldNotHaveValidationErrorFor that can make it easier to write unit tests for validators.

Unit tests – materials from trainings for quality engineers

I would like to invite you to familiarize with materials from training about unit tests. This training has been prepared as part of my work duties in Objectivity Bespoke Software Specialists. The main goal of this training was to learn quality engineers that work in Objectivity how to write unit tests. The training has been divided into two parts: Unit Tests - The Beginning – this is an introduction to unit tests; you will learn: what unit tests are, how to develop them correctly, how you can cooperate in project to build better unit tests, how unit tests work.

Main purpose of this library is to minimize the ‘Arrange’ phase of unit tests in order to maximize maintainability. Presentation is available on GitHub – AutoFixture - Lightning talk. You will find there description of main features of this library. Moreover, presentation contains short comparison AutoFixture with other available solutions. Of course on GitHub you will find code used in presentation.

SQL unit tests – coverage report

Nowadays, it is quite common to write unit tests for code that we are creating, but not for all programming languages. When we are writing code for www, desktop or mobile application we get used to write unit test for code that is related to application. Together with that we are not testing database code. It is correct when we are using some ORM tools because such tools generate code for us. Situation looks quite different when we are writing SQL code by our own. Then this code should be unit tested similar to other production code. To do that [...]

Mocking DbContext and DbSet with Moq

I believe that during your work with unit tests with applications that are using database for data storage you will need to isolate layer that is responsible for providing data. In this example I will use Entity Framework as ORM. Below you can find main elements of solution: public class User { public int Id { get; set; } public string Login { get; set; } public string Name { get; set; } public string Surname { get; set; } public bool AccountLocked { get; set; } public virtual List<Role> Roles { get; set; } } public class UsersContext [...]
