assert for no errors

[Eliyaan]

Describe the feature

To be able to assert whether or not the function returns an error.

fn foo() !MyStruct 

assert foo // fails if Result type is returned

Use Case

To be able to check for no errors in tests files. The Result type is very useful for handling errors and I think that being able to test them with v test goes hand in hand with it's purpose to handle errors properly. (I dont have a specific syntax in mind)

For tests is works well like that :

fn test_abc() {
    foo()!
}

Where there is an error, it propagates the error and the test fails
