(Custom) attributes for testcases in generated code

[304NotModified]

So I was thinking over #476

I would be could cool if we could add attributes to the generated tests

E.g. instead of the current generation:

[NUnit.Framework.TestAttribute()]
[NUnit.Framework.DescriptionAttribute("MyTest")]
public async System.Threading.Tasks.Task MyTest()

we could generate with a Order attribute:

[NUnit.Framework.TestAttribute()]
[NUnit.Framework.DescriptionAttribute("MyTest")]
[NUnit.Framework.Order(2)]
public async System.Threading.Tasks.Task MyTest()

Or with even a custom attribute

[NUnit.Framework.TestAttribute()]
[NUnit.Framework.DescriptionAttribute("MyTest")]
[MyProject.MyCustomAttribute("yes)]
public async System.Threading.Tasks.Task MyTest()

This would be great as there are many attributes you sometimes like to use.

I checked the code generation (NUnit3TestGeneratorProvider) and I think something like this could work:

@Retry(2)
Scenario: Client has a simple basket
    Given the client started shopping
    And the client added 1 pcs of "Electric guitar" to the basket
    When the basket is prepared
    Then the basket price should be $180

And you define some mapping, for example in reqnroll.json

{
    "attributeMapping": {
        "tests": {
            "Retry\\((\\d+)\\)": "NUnit.Framework.CategoryAttribute(\"Retry($1)\")"
        }
    }
}

(Bit hard to do Regex in JSON, but it could work - regex example: https://regex101.com/r/jMAN4H/1)

Would that work?

In the future you also need that for testclasses I guess

questions:

• Good idea?
• Is regex a good idea?
• Should this be a decorator like the IgnoreDecorator? Or in the UnitTestGeneratorProviders?
• How do we get the config in such decorator/provider?
• Config in json and/or in code? (As method?)

I don't know if you are aware of it, but this is currently possible already with generator plugins. You need to have a named registration for either the ITestClassDecorator ot the ITestMethodDecorator interferences. See https://docs.reqnroll.net/latest/extend/decorators.html

Cool! I missed that indeed :)
