TestSubscriber (RxJava Javadoc 2.2.21)

java.lang.Object
- io.reactivex.observers.BaseTestConsumer<T,TestSubscriber<T>>
- - io.reactivex.subscribers.TestSubscriber<T>

Type Parameters:

T - the value type

All Implemented Interfaces:

Disposable, FlowableSubscriber<T>, Subscriber<T>, Subscription
```
public class TestSubscriber<T>
extends BaseTestConsumer<T,TestSubscriber<T>>
implements FlowableSubscriber<T>, Subscription, Disposable
```
A subscriber that records events and allows making assertions about them.
You can override the onSubscribe, onNext, onError, onComplete, request and cancel methods but not the others (this is by design).
The TestSubscriber implements Disposable for convenience where dispose calls cancel.
When calling the default request method, you are requesting on behalf of the wrapped actual subscriber.

- Constructor Detail
  - TestSubscriber
```
public TestSubscriber()
```
    Constructs a non-forwarding TestSubscriber with an initial request value of Long.MAX_VALUE.
  - TestSubscriber
```
public TestSubscriber(long initialRequest)
```
    Constructs a non-forwarding TestSubscriber with the specified initial request value.
    The TestSubscriber doesn't validate the initialRequest value so one can test sources with invalid values as well.
    
    Parameters:
    
    initialRequest - the initial request value
  - TestSubscriber
```
public TestSubscriber(Subscriber<? super T> downstream)
```
    Constructs a forwarding TestSubscriber but leaves the requesting to the wrapped subscriber.
    
    Parameters:
    
    downstream - the actual Subscriber to forward events to
  - TestSubscriber
```
public TestSubscriber(Subscriber<? super T> actual,
                      long initialRequest)
```
    Constructs a forwarding TestSubscriber with the specified initial request value.
    The TestSubscriber doesn't validate the initialRequest value so one can test sources with invalid values as well.
    
    Parameters:
    
    actual - the actual Subscriber to forward events to
    
    initialRequest - the initial request value
- Method Detail
  - create
```
public static <T> TestSubscriber<T> create()
```
    Creates a TestSubscriber with Long.MAX_VALUE initial request.
    
    Type Parameters:
    
    T - the value type
    
    Returns:
    
    the new TestSubscriber instance.
  - create
```
public static <T> TestSubscriber<T> create(long initialRequested)
```
    Creates a TestSubscriber with the given initial request.
    
    Type Parameters:
    
    T - the value type
    
    Parameters:
    
    initialRequested - the initial requested amount
    
    Returns:
    
    the new TestSubscriber instance.
  - create
```
public static <T> TestSubscriber<T> create(Subscriber<? super T> delegate)
```
    Constructs a forwarding TestSubscriber.
    
    Type Parameters:
    
    T - the value type received
    
    Parameters:
    
    delegate - the actual Subscriber to forward events to
    
    Returns:
    
    the new TestObserver instance
  - onSubscribe
```
public void onSubscribe(Subscription s)
```
    Description copied from interface: FlowableSubscriber
    
    Implementors of this method should make sure everything that needs to be visible in Subscriber.onNext(Object) is established before calling Subscription.request(long). In practice this means no initialization should happen after the request() call and additional behavior is thread safe in respect to onNext.
    
    Specified by:
    
    onSubscribe in interface FlowableSubscriber<T>
    
    Specified by:
    
    onSubscribe in interface Subscriber<T>

```
protected void onStart()
```
    Called after the onSubscribe is called and handled.
  - onNext
```
public void onNext(T t)
```
    Specified by:
    
    onNext in interface Subscriber<T>

public final void dispose()
```
    Description copied from interface: Disposable
    
    Dispose the resource, the operation should be idempotent.

    Assert that the onSubscribe method was called exactly once.
