Add an API for custom test method parameter injection

I need a way to inject a custom parameter into TestNG’s test methods. The parameter is my own object constructed dynamically at runtime from test method annotations. The custom parameter is not known to TestNG, it’s my own type, e.g.:

@com.mypackage.MyAnnotation("someValue)"
@org.testng.Test
public void test(MyCustomObject val) {
    ...
}

It looks like right now I cannot do it easily.

Can we add such functionality/SPI? What is the current easiest way to achieve that?

Would be very useful I have the same needs

this is true @juherr, i ended doing it this way. But, the only thing that misses is the abilitty to set a default dataProvider for all tests, in my case, my data provider is generics and passes only if there is certain annotations

i think that a combination of the dataProvider and adding the ability to set a default provider or provider class would do the trick and will open a hole new possibilities
