How to mock Mule ESB HTTP outbound Connector in a Functional Unit Test Case?

I am writing a Functional Unit test case to test a Mule Flow containing an inbound and outbound HTTP connector. The flow contains the following components:
An inbound HTTP connector that listens to a rest service call say http://localhost:8080/restapi/id
A logger that displays the id in the logs
A web service consumer that sends the soap request to server2 at the wsdl : http://server2:8080/sample.wsdl
A java component that reads recieves the output from server2 and forms the response for client.
In the functional Unit test case, I am trying to mock the HTTP outbound connector calling the serevr2.
How can I do this?
The flow configuration file code is as below:

Error in sending email in Anypoint Studio (MuleSoft)

Everytime I try to send an email in AnyPoint Studio I get an error. I've tried sending it from other computers and it always works. It just doesn't seem to work in mine and I have no idea why.
This is my .xml:

When I open the browser and type localhost:8081/sendemail, no email is sent and the browser prints this message.

Funny thing is, I tested the exact same xml in other computers and it works.

I would first test if your computer has connectivity to the Gmail servers.
Try "telnet smtp.gmail.com 587" or the Mac equivalent.

I can't see the port "587" in your flow.You can try the following configuration:
<smtp:outbound-endpoint
connector-ref="emailConnector"
host="smtp.gmail.com"
port="587"
user="<account name>%40gmail.com"
password="<password>"
to="<email addresses>"
from="<account name>#gmail.com"
subject="Test email message"/>
Also check if you have access to call the smtp.gmail.com from your local network

Mule ESB + TOMCAT Web Application Integration

I have a Spring MVC Web application that performs CRUD operations on Tomcat Server. Can I use Mule ESB as a request handler before Tomcat. For example, users request to localhost:8181/user/create (Mule ESB Port) and Mule redirect request to localhost:8080/user/create (Tomcat Server Port) and sends response back over mule. I am using Mule ESB for webservices, but I don't understand how can I use Mule ESB for web application requests.

You can use the new HTTP module released in 3.6 and create a proxy using this flow:

How to disable tempQueues in Async AMQP-RabbitMQ Implementation in Mule?

How am i supposed to disable the amqp-gen queues that creates automatically? in Mule ActiveMQ i got a "disableTemporaryReplyToDestinations" property, by setting that to 'true' and doing a one-way exchange-pattern, i'm able to implement async messaging.
Now with AMQP/RabbitMQ it's a different story, i do have the one-way exchange pattern but i dont have any property to set from the component side inside MuleStudio that tells me to disable those, i can't even disable it from the RabbitMQ Panel.
How do i disable those tempQueues (called amqp-gen in AMQP) which are not needed for an async implementation?
This is my test XML

Your "issue" is not related to temporary queues and trying to disable them but in fact is a feature called "private queues" (see the doc for more information).
Basically, because you do not name the queues you declare in your AMQP inbound and outbound endpoints, RabbitMQ consider them as private to your connection and give them generated names.
Use the queueName attribute to configure queue names on your AMQP endpoints and things will work as you intend.
