Class CommandBehavior<TInput, TOutput, TCommandOutput, TConfiguration>

Sets a function that will be called on any Client#send() invocation.

Sets a function that will be called on any Client#send() invocation.

Can be chained so that successive invocations call different functions. When there are no more callsFakeOnce() functions to use, invocations will call a function specified by callsFake().

Example

clientMock
  .callsFakeOnce(cmd => 'first call')
  .callsFakeOnce(cmd => 'second call')
  .callsFake(cmd => 'default');

Allows specifying the behavior for a given Command type and its input (parameters).

If the input is not specified, it will match any Command of that type.

Allows specifying the behavior for any Command with given input (parameters).

If the input is not specified, the given behavior will be used for any Command with any input.

Calling onAnyCommand() without parameters is not required to specify the default behavior for any Command, but can be used for readability.

Example

clientMock.onAnyCommand().resolves(123)

is same as:

clientMock.resolves(123)

Sets a failure response that will be returned from any Client#send() invocation. The response will always be an Error instance.

Sets a failure response that will be returned from one Client#send() invocation. The response will always be an Error instance.

Can be chained so that successive invocations return different responses. When there are no more rejectsOnce() responses to use, invocations will return a response specified by rejects().

Example

clientMock
  .rejectsOnce('first call')
  .rejectsOnce('second call')
  .rejects('default');

Sets a successful response that will be returned from any Client#send() invocation.

Sets a successful response that will be returned from one Client#send() invocation.

Can be chained so that successive invocations return different responses. When there are no more resolvesOnce() responses to use, invocations will return a response specified by resolves().

Example

clientMock
  .resolvesOnce('first call')
  .resolvesOnce('second call')
  .resolves('default');
