  - context
```
public Context context()
```
    Description copied from interface: ContextSupport
    
    Provide a context.
    Since calls to this method shall only be triggered when a Mutiny pipeline uses a withContext operator, there is no need in general for caching the context value in a field of the implementing class. Exceptions include operators that have cross-subscriber semantics such as memoizers or broadcasters.
    This method is expected to be called once per withContext operator.
    
    Specified by:
    
    context in interface ContextSupport
    
    Returns:
    
    the context, must not be null.
  - onSubscribe
```
public void onSubscribe(UniSubscription subscription)
```
    Description copied from interface: UniSubscriber
    Event handler called once the subscribed Uni has taken into account the subscription. The Uni have triggered the computation of the item.
    IMPORTANT: UniSubscriber.onItem(Object) and UniSubscriber.onFailure(Throwable) would not be called before the invocation of this method.
    
    Executor: Operate on no particular executor, except if Uni.runSubscriptionOn(Executor) has been called
    
    Exception: Throwing an exception cancels the subscription, UniSubscriber.onItem(Object) and UniSubscriber.onFailure(Throwable) won't be called
    Specified by:
    
    onSubscribe in interface UniSubscriber<T>
    
    Parameters:
    
    subscription - the subscription allowing to cancel the computation.
  - onItem
```
public void onItem(T item)
```
    Description copied from interface: UniSubscriber
    Event handler called once the item has been computed by the subscribed Uni.
    IMPORTANT: this method will be only called once per subscription. If UniSubscriber.onFailure(Throwable) is called, this method won't be called.
    
    Executor: Operate on no particular executor, except if Uni.emitOn(java.util.concurrent.Executor) has been called
    
    Exception: Throwing an exception cancels the subscription.
    Specified by:
    
    onItem in interface UniSubscriber<T>
    
    Parameters:
    
    item - the item, may be null.
  - onFailure
```
public void onFailure(java.lang.Throwable failure)
```
    Description copied from interface: UniSubscriber
    Called if the computation of the item by the subscriber Uni failed.
    IMPORTANT: this method will be only called once per subscription. If UniSubscriber.onItem(Object) is called, this method won't be called.
    
    Executor: Operate on no particular executor, except if Uni.emitOn(java.util.concurrent.Executor) has been called
    
    Exception: Throwing an exception cancels the subscription.
    Specified by:
    
    onFailure in interface UniSubscriber<T>

    Returns:
    
    this UniAssertSubscriber
  - awaitItem
```
public UniAssertSubscriber<T> awaitItem(java.time.Duration duration)
```
    Awaits for a item event at most duration.
    If the timeout expired, or if a failure event is received instead of the expected completion, the check fails.

```
public UniAssertSubscriber<T> awaitFailure(java.util.function.Consumer<java.lang.Throwable> assertion)
```
    Awaits for a failure event and validate it. It waits at most AssertSubscriber.DEFAULT_TIMEOUT.
    If the timeout expired, or if an item event is received instead of the expected failure, the check fails. The received failure is validated using the assertion consumer. The code of the consumer is expected to throw an AssertionError to indicate that the failure didn't pass the validation. The consumer is not called if no failures are received.

    assertion - a check validating the received failure (if any). Must not be null
    
    Returns:
    
    this UniAssertSubscriber

    If the timeout expired, or if an item event is received instead of the expected failure, the check fails.
    
    Parameters:
    
    duration - the max duration to wait, must not be null
    
    Returns:
    
    this UniAssertSubscriber
  - awaitFailure
