Class SafeCheck<T extends Throwable>

java.lang.Object

pl.wkr.fluentrule.api.check.SafeCheck<T>

Type Parameters:

T - expected type of thrown exception

All Implemented Interfaces:

Check

public abstract class SafeCheck<T extends Throwable>
extends Object
implements Check

Type safe implementation of Check interface. Ensures that thrown exception has expected type and pass it to safeCheck(Throwable) method. Should be used for anonymous classes. Commonly used in conjunction with Assertj assertions in callback's body.

Usage with CheckExpectedException rule:

 @Rule
 public CheckExpectedException thrown = CheckExpectedException.none();

 @Test
 public void test_state_with_type_safe_check() throws NotEnoughMoney {
      thrown.check(new SafeCheck() {
          protected void safeCheck(NotEnoughMoney notEnoughMoney) {
              assertThat(notEnoughMoney.getLackingMoney()).isEqualTo(3);  //assert custom exception
          }
      });
 }
