Mocking SubFlow in Mule - mule

I am trying to create MUnit for the below flow.
<?xml version="1.0" encoding="UTF-8"?>

</sub-flow>
</mule>
I have create two test flows for subflow, which is working fine.
Eventhough I mocked subflow to test the main flow, the flow is executing the sub flow. Any ideas if I am missing something while mocking the sub flow. Any help will be highly appreciated.
This is my testsuite

The culprit is this

The name should be name not doc:name

How to add multiple http request calls in foreach | Mule 3

I am using scatter-gather to call many endpoints with the same host and different paths. How can I add the HTTP request connector inside For Each scope, that can loop into the different paths and add the payload to the same file?
My code is as below, I would like to loop over the HTTP request;

Check the below sample code how we can use foreach in your scenario. THis is in Mule4. I hope you can do it in Mule3 as well.
I am not sure why you want to use foreach. I would suggest use Scatter_Gather instead of foreach. Because foreach will work sequentially and Scatter_Gather works concurrently. Performance wise concurrent process is good.

Set a variable with an empty list before the foreach, and for each iteration concatenate the results. I guess you can set a list of the paths and use it to iterate the foreach.

Mule 3.8.3 Runtime - Database connector - using query from flow variable returns java.lang.IllegalArgumentException

I'm not able to refer the query from flowVariable inside database connector. I have read that it was a known issue in mule 3.5. I'm not sure if it is still an open issue in 3.8. Do any one know about it ?
Below is the flow -

It works fine if I replace the #[flowVars.sqlStatement] with Insert into countrylanguage (countrycode, language, percentage, isofficial) values(#[payload.CountryCode], #[payload.Language],#[payload.Percentage], #[payload.IsOfficial])
Any pointers would be helpful. Thanks in advance.
Instead using <db:parameterized-query> try with <db:dynamic-query> like following
<db:insert config-ref="MySQL_Configuration5" doc:name="Database">
<db:dynamic-query><![CDATA[#[flowVars.sqlStatement]]]></db:dynamic-query>

Making call to Rest services in mule ESB

I have made a web app which call mule server which is listening to http inbound point at 8081 for accessing the database.I am accessing the database successfully and getting a message. But I want to access the other rest services after I get the object from the database and run some operations.
I don't know how to achieve this.
Please give me example. I am posting my flow.

I recommend to use http:outbound-endpoint to consume a REST service (GET,POST, PUT or DELETE). In this example you can see a flow to invoke a services GET:
<flow name="invoke-ws" doc:name="invoke-ws">
<vm:inbound-endpoint exchange-pattern="request-response" path="vm-ws" doc:name="VM"/>
<logger message="payload is: #[payload]" level="INFO" doc:name="Logger"/>
<http:outbound-endpoint exchange-pattern="request-response" method="GET" address="http://ip:port/service/#[payload]" doc:name="HTTP">
<set-property propertyName="Accept" value="application/json"/>
</http:outbound-endpoint>
<byte-array-to-string-transformer doc:name="Byte Array to String"/>
<logger message="payload is: #[payload]" level="INFO" doc:name="Logger"/>
</flow>
If the service is SOAP over HTTP, I recommend using http://www.mulesoft.org/documentation/display/current/Web+Service+Consumer

Mule ESB Until-Successful Not Working Properly

I have spent the past few hours trying to get until-successful to work properly, but to no avail even after following the model here: "http://blogs.mulesoft.org/meet-until-successful-store-and-forward-for-mule/". The main flow that uses until-successful is SEND_TO_POST_SERVICE. I want until-successful to continue running the referenced flow until the max retries. Below are my flows and relevant information. The internal Mule server version is 3.4, and the Mule Studio version is 3.4.0

The flow you are flow-refing (ie CONNECT_TO_POST_SERVICE) is a private flow not a sub-flow.
This means that exceptions thrown in it will not be propagated to the caller. Change it to a sub-flow and it should work.
PS. Also remove the processor-chain in CONNECT_TO_POST_SERVICE: it's completely useless.

Mule file download with HTTP Endpoint

My HTTP Endpoint responsible for downloading the file at the end of the flow is erroring out. It keeps trying to communicate with http://:80/ instead of the URL passed in. What am I doing wrong here?

I can't spot the error: your flow looks good (except a problem I'll detail below) so, alternatively to using an http:outbound-endpoint, which can be finicky at times, you could use the http:rest-service-component.
Your next problem will be in the outputPattern of the file endpoint: remember at this point message.payload will be the response from the HTTP endpoint not the (partial) URL anymore. You need to pre-compute the file name and store it in a flow variable, then use it.
This would give:
