<p>Take for example the following test of Azure ML (Azure Machine Learning) integration with NAV.</p>
|
||||
<p>Context: Azure Machine Learning services are paid. However, Dynamics NAV includes a monthly pre-paid quota of Azure ML, which can be used for free by the users. There is an upper limit to this quota, and when it is reached, Azure ML services are turned off until the next month starts and a new quota becomes available for consumption.</p>
|
||||
<p>The test below checks that, when the monthly quota is exceeded, then the function IsAzureMLLimitReached returns TRUE.</p>
