Test creating/encoding a refresh message by EMA Java

Akechi Sato

I am testing creating a refresh message which payload is Series
in a consumer application. After Msg.payload(payload) is called, I check the
result in the consumer application but nothing is set. Please help.

Hello @Akechi.Sato

To test creating/encoding a refresh message by EMA, you can use
one of the possible 2 ways

A) Use
TestUtilities class shipped with Elektron-SDK Java package since version 1.1.1 to help to perform the unit test. EMA
also provides example source code to test creating/encoding EMA refresh message
in testRefreshMsg_EncodeDecode() method as snipped source code shown below:

public void testRefreshMsg_EncodeDecode()
    {
        TestUtilities.printTestHead("testRefreshMsg_EncodeDecode", "ema encoding ema decoding");

        com.thomsonreuters.upa.codec.DataDictionary dictionary = com.thomsonreuters.upa.codec.CodecFactory.createDataDictionary();
        TestUtilities.upa_encodeDictionaryMsg(dictionary);

        com.thomsonreuters.ema.access.FieldList fl = EmaFactory.createFieldList();

        TestUtilities.EmaEncodeFieldListAll(fl);

        com.thomsonreuters.ema.access.RefreshMsg refreshMsg = EmaFactory.createRefreshMsg();

        System.out.println("Begin EMA RefreshMsg test after constructor");

        TestUtilities.checkResult(refreshMsg.domainType() == com.thomsonreuters.ema.rdm.EmaRdm.MMT_MARKET_PRICE, "RefreshMsg.domainType()");

        TestUtilities.checkResult(refreshMsg.streamId() == 0, "RefreshMsg.streamId()");

        TestUtilities.checkResult(!refreshMsg.hasPartNum(), "RefreshMsg.hasPartNum()");

        TestUtilities.checkResult(!refreshMsg.hasSeqNum(), "RefreshMsg.hasSeqNum()");

        TestUtilities.checkResult(!refreshMsg.hasQos(), "RefreshMsg.hasQos()");

        TestUtilities.checkResult(!refreshMsg.hasMsgKey(), "RefreshMsg.hasMsgKey()");

...

The method is in RefreshMsgTests.java
located in
<Elektron_Java_SDK>\Ema\TestTools\UnitTests\Tests\com\thomsonreuters\ema\unittest.
You can modify the method to create a refresh message that you want to test and
check the result.

or

Modify
a provider application to create/encode a refresh message that you want to test.
Then, run the provider application. Next, run a consumer application to connect
to it directly and receive the refresh message. Then, you can check in the
consumer application if the refresh message sent from the provider application
is correct or not.

For
a provider application creating/encoding a refresh message with Series payload
(dictionary response), please refer to example332__Dictionary__UserControl in
<Elektron_Java_SDK>\Ema\Src\examples\java\com\thomsonreuters\ema\examples\training\iprovider\series300.
For the consumer application which can request/receive dictionary response from
example332__Dictionary__UserControl, please refer to
example332__Dictionary__Streaming in
<Elektron_Java_SDK>\Ema\Src\examples\java\com\thomsonreuters\ema\examples\training\consumer\series300.
