Successful etl
More information on how to define an etl in a system-under-test can be found there.
The process for testing that an etl run successfully (no failure during the execution, the result of the execution is a success) is really straightforward: you run your etl and check the state at the end of the execution. If the package returns a valid status then the test is successful else it fails. To achieve this, in addition of the etl defined in the system-under-test you will need to define an xml element named successful within the assertion.
A full sample would be:
<test name="Etl is successful" uid="0001">
<system-under-test>
<execution>
<etl path="Etl\" name="Sample.dtsx">
<parameter name="DestinationPath">C:\toto.txt</parameter>
</etl>
</execution>
</system-under-test>
<assert>
<successful/>
</assert>
</test>
To assert that a run is not successful just add a not attribute to the successful element.
<test name="Etl is successful" uid="0001">
<system-under-test>
...
</system-under-test>
<assert>
<successful not="true"/>
</assert>
</test>
