Bringing Jest-esque Snapshot testing to C#
Snapper is a NuGet library which makes snapshot testing very easy in C#. Snapshot testing can simplify testing and is super useful when paired with Golden Master testing or contract testing APIs. It is very heavily based on Jest Snapshot Testing framework.
See https://theramis.github.io/Snapper/ for the full documentation.
What is Snapper?
The best way to describe what Snapper does by going through an example. Imagine you have the following test where are retrieving a user from a service.
[Fact]
public void MyTest()
{
var myUser = _userService.GetUser(id);
Assert.Equal("MyUser", myUser.Username);
Assert.Equal("email@example.com", myUser.Email);
Assert.Equal("myhash", myUser.PasswordHash);
...
...
}
As you can imagine the assertion steps in the test can get very long and hard to read. Now lets see what the test would look like if Snapper is used.
[Fact]
public void MyTest()
{
var myUser = _userService.GetUser(id);
myUser.ShouldMatchSnapshot();
}
