Hello Everyone! Welcome to PRP Coding YouTube channel. I am Praveen Raveendran Pillai.
In this session I shall explain about
1. What is Assertion?
2. What is Fluent Assertion?
3. How to install Fluent Assertion nugget package in xUnit .Net project?
4. How to replace the xUnit Assert class with Fluent Assertion extension methods?
Assertions are the gatekeepers of unit testing. They are statements that express the expected behaviour of your code.
Assertions typically consist of two components:
Actual Result: The output produced by executing the code being tested.
Expected Result: The predefined outcome you anticipate based on the input or conditions provided to the code.
Unit tests are usually a must-have part of building and maintaining a software application.
If they don't align, the test fails, signalling a potential issue in your code.
Now let’s learn about fluent assertions in c#.
Fluent Assertions is a set of .NET extension methods that allow you to more naturally specify the expected outcome of a TDD or BDD-style unit test.
The goal of Fluent Assertions is to make unit tests easier to write and read. These extension methods read like sentences.
Fluent Assertions unique features and a large set of extension methods achieve these goals.
This makes it easy to understand what the assertion is testing for.Additionally, test failures by Fluent Assertions are very clear as to why the Assertion has failed.
