NbpTestSubscriber (rxjava2-backport 2.0.0-RC2 API)

java.lang.Object
- hu.akarnokd.rxjava2.subscribers.nbp.NbpTestSubscriber<T>

Type Parameters:

T - the value type

All Implemented Interfaces:

Disposable, NbpObservable.NbpSubscriber<T>
```
public class NbpTestSubscriber<T>
extends java.lang.Object
implements NbpObservable.NbpSubscriber<T>, 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 desing).
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 Summary

Constructors
Constructor and Description
`NbpTestSubscriber()` Constructs a non-forwarding TestSubscriber with an initial request value of Long.MAX_VALUE.
`NbpTestSubscriber(NbpObservable.NbpSubscriber<? super T> actual)` Constructs a forwarding TestSubscriber but leaves the requesting to the wrapped subscriber.

```
public void assertComplete()

    Assert that this TestSubscriber received exactly the specified onError event value.
    The comparison is performed via Objects.equals(); since most exceptions don't implement equals(), this assertion may fail. Use the assertError(Class) overload to test against the class of an error instead of an instance of an error.
    
    Parameters:
    
    error - the error to check
    
    See Also:
    
    assertError(Class)
  - assertError

    Asserts that this TestSubscriber received exactly one onError event which is an instance of the specified errorClass class.
    
    Parameters:
    
    errorClass - the error class to expect
  - assertValue
```
public final void assertValue(T value)
```
    Assert that this TestSubscriber received exactly one onNext value which is equal to the given value with respect to Objects.equals.
    
    Parameters:
    
    value - the value to expect
  - assertValueCount
```
public final void assertValueCount(int count)
```
    Assert that this TestSubscriber received the specified number onNext events.
    
    Parameters:

    Assert that the TestSubscriber received only the specified values in the specified order.
    
    Parameters:
    
    values - the values expected

  - assertValueSet
```
public final void assertValueSet(java.util.Collection<? extends T> values)

```
public final void assertSubscribed()
```
    Assert that the onSubscribe method was called exactly once.
  - assertNotSubscribed
```
public final void assertNotSubscribed()
```
    Assert that the onSubscribe method hasn't been called at all.

```
    Waits until the any terminal event has been received by this TestSubscriber or returns false if the wait has been interrupted.
    
    Returns:
    
    true if the TestSubscriber terminated, false if the wait has been interrupted
  - awaitTerminalEvent
```
public boolean awaitTerminalEvent(long duration,

```
    Awaits the specified amount of time or until this TestSubscriber receives an onError or onComplete events, whichever happens first.
    
    Parameters:
    
    duration - the waiting time
    
    unit - the time unit of the waiting time
    
    Returns:
    
    true if the TestSubscriber terminated, false if timeout or interrupt happened
  - assertErrorMessage
```
public void assertErrorMessage(java.lang.String message)
```
  - getEvents
```
public java.util.List<java.util.List<java.lang.Object>> getEvents()
```
