Relation between objects

The concept of relations between objects has only been implemented for SSAS (multidimensional) at the moment. It lets you validate that a dimension is linked to a measure-group or reciprocally that a measure-group is linked to a dimension. In the future we plan to do the same for tables in a SQL model (foreign keys).

For this kind of test, NBi proposes an assertion named linkedTo. To use it you must define a system-under-test with a structure of type dimension or measure-group.

<system-under-test>
	<structure>
		<dimension caption="Customer" perspective="Adventure Works"/>
	</structure>
</system-under-test>

When done, you’ll have to define your assertion as an xml elemened named linkedTo and specify in the xml attribute caption the measure-group or dimension that you’re expecting linked to the previous element. Note that inside this linkedTo element you don’t need to specify the perspective of the dimension or measure-group, this information will be inferred from the system-under-test.

<assert>
	<linkedTo>
		<measure-group caption="Internet Sales"/>
	</linkedTo>
</assert>

Here under, you’ll find a sample for both elements (dimension linked to measure-group and measure-group linked to dimension).

			</structure>
		</system-under-test>
		<assert>
			<linkedTo>
				<measure-group caption="Internet Sales"/>
			</linkedTo>
		</assert>
	</test>
	<test name="Measure-group 'Internet Sales' is linked to dimension 'Internet Sales' throw perspective 'Adventure Works'" uid="0001">
		<system-under-test>
			<structure>
				<measure-group caption="Internet Sales" perspective="Adventure Works"/>
			</structure>
		</system-under-test>
		<assert>
			<linkedTo>
				<dimension caption="Customer"/>
			</linkedTo>
		</assert>
	</test>
</testSuite>
