Respawn VS FluentValidation

ImMemoryDb isnt recommended for testing as it doesnt behave as a real database. Save yourself trouble and use a real database paired with Respawn.

I come from a .NET background and in the .NET environment I used to seed the database with the necessary data on each test and then clean the database at the end of the test using the Respawn library.

This was our initial approach (using sqlite) but our migrations take a while to run and this resulted in slow tests. Using Respawn to clean the db significantly improved test performance (https://github.com/jbogard/Respawn)

Have you used something like Respwan https://github.com/jbogard/Respawn instead of creating and cleaning or deleting database every time? Not sure if it would help you. But I thought it might make your workflow little simpler. Respawn lets to restore db to a restore point.

NUnit, FluentAssertions, Moq & Respawn

You will need a separate test database purely for integration tests. You will need to reset the state of the DB every time using something like https://github.com/jbogard/Respawn. I always use the (localdb)\mssqllocal SQL instance that comes as standard with VS for dev and integration test databases.

Here is an example of Command handler with built-in Fluent Validation and fire and forget style:

There is an RFC called Problem Details (RFC7807) that standardizes how an error in an API should be responded to for the client. If you use Fluent validation, you may have noticed that the response is within this pattern.

here we're defining the input validation requirements using fluent validation rules. let's see what happens when the user input doesn't meet the above criteria. execute the same request in swagger with the following incorrect json content:

I remember FluentValidation being a nice library for this type of stuff.

Literally the code example in the front page: https://fluentvalidation.net/

Mature c# projects purposely maintain no downstream dependencies and is they do, it's to a major reputable lib. See for yourself - these are staple third party packages commonly used. Anything dependency starting with System or NETStandard is Microsoft maintained.

FluentValidator for validating and authorising certain fields.

Now that we know the importance of providing users with enough information about their requests and how it was processed, let’s focus on how we can configure our API to help us do that.One aspect of such meaningful experience is Request Validation (400 Error Range). For that purpose I am using a library called Fluent Validation.
