Naive implementation would be to add methods like this:
// Current method
def Before(tagExpression: String)(body: Scenario => Unit): Unit = {
Before(tagExpression, DEFAULT_BEFORE_ORDER)(body)
}
// Added method
def Before(tagExpression: String)(body: => Unit): Unit = {
Before(tagExpression, DEFAULT_BEFORE_ORDER)(_ => body)
}
But from a user perspective, you get errors "Cannot resolve overloaded method 'Before'".
After having a look, I came up with a solution that I don't think it's worth shipping because it would:
- bring some complexity in the code (similar to what is done for
Step
inScalaDsl
) - bring a breaking change to the users (need to write
Before() { }
orBefore(order= 2) { }
)
What I ended up writing:
sealed trait HookType
case object BeforeType extends HookType
// TODO other types
val Before = new Hook(BeforeType)
// TODO other vals
final class Hook(hookType: HookType) {
def apply(tagExpression: String = EMPTY_TAG_EXPRESSION, order: Int = DEFAULT_BEFORE_ORDER): HookImpl = new HookImpl(hookType, tagExpression, order)
}
final class HookImpl(hookType: HookType, tagExpression: String, order: Int) {
def apply(body: HookBody): Unit = {
hookType match {
case BeforeType =>
registry.beforeHooks += ScalaHookDetails(tagExpression, order, body)
// TODO other cases
}
}
def apply(body: => Unit): Unit = {
apply(_ => body)
}
}
If anyone has an idea how to implement it easily, please shout :)

Actually, after a day of reflexion and after implementing the ParameterType
stuff, the solution became obvious and there is no breaking change.
