Domain-driven design bottom up

Qowaiv is a (Single) Value Object library. It aims to model reusable, immutable, (Single) Value Objects that can be used a wide variety of modeling scenarios, both inside and outside a Domain-driven context.

Package

This package contains helpers to make writing unit tests for SVO's easier.

IO

Temporary directory

Testing IO can be cumbersome. The TemporaryDirectory can help by creating a directory that only exists for the duration of a test:

using (var directory = new TemporaryDirectory()
{
     var file = directory.CraeteFile("somefile.txt");
     // ..
}

On the dispose, the directory, and all it children will be deleted.

File lock

To test IO related unhappy flows, it can be useful to create a temporary lock on a file. This can be done as follows:

var file = new FileInfo("somefile.txt");

using (var @lock = file.Lock())
{
     file.OpenRead(); // Throws IOException.
}
