Interface AssertProvider<A>

Type Parameters:

A - the type of the assert (not typed - to allow any kind of assert)

public interface AssertProvider<A>

Provides a Assert for the current object.

Used to map an object to its Assert without having to create a new "Assertions" class.

Usage:

 public class Button implements AssertProvider<ButtonAssert> {
   public ButtonAssert assertThat() { 
     return new ButtonAssert(this); 
   } 
 }
 
 public class ButtonAssert extends Assert {
   public ButtonAssert containsText(String text) {
     ...
   }
 }
 
 void testMethod() {
   Button button = ...;
   
   // First option
   Assertions.assertThat(button).containsText("Test");
   
   // Second option
   button.assertThat().containsText("Test");
 }
