Run Unit Tests via Azure DevOps
Two important unit tests you might want to perform in your Azure project are related to maps and reusable functions. Either use the Microsoft Test Framework or XUnit for .Net Core.

Deal with empty DateTime in XSD and XSLT
For the XML fans among us. How do you validate a datetime field that can be empty? How can you use an XSLT to set a datetimefield to the inout datetime or the current datetime (when empty).
Perform Null Check in Logic App
You can’t directly test against null or undefined in a Logic App, but you can try a work-around using coalesce (return string value if null).
Logic App Debugging in Serverless360
You can get an overview of logic app runs to find out which logic apps actually failed. Via the sequence number you can lookup the message in the servicebus.
Servicebus Tooling in Serverless360
You can use Serverless360 to execute a number of tasks on a servicebus queue or topic. You can for instance edit messages and perform a manual or automated resubmit.
Introducing Serverless360
Managing and monitoring of iPaaS applications via the Azure Portal only is often not enough. Via the Azure Portal, we can get insights into a single logic app or servicebus, but we will not have an overview of the entire process. Serverless360 formerly actually fills the gap. It allows for monitoring at the application level as well as a consolidated monitoring view.
Batch Processing in Logic Apps
Larger amounts of messages quickly lead to an overload of messages. The solution is to dispense the message load by replacing Azure Event Grid messaging by Azure Service Bus messaging.
Exception Handling in Logic Apps
You can implement exception handling in Logic Apps via the RunAfter construct at the scope level. When you specify exception handling at the scope level, exception handling is enabled on all contained actions and and an array of failed action responses is returned. That sounds good, but there are a few snags to take into account.
ServiceBus Next Available
You can combine singleton and concurrent processing in a queuing solution by using servicebus sessions. When sending messages to the servicebus, set SessionId equal to the unique Id of the client. On receiving messages from the servicebus, set SessionId to Next Available.
Using Parameters and Variables in Logic Apps
Using parameters and variables in Workflow Definition Language can be tempting. The examples are chosen quite randomly, but hopefully they will help you when parameterizing your logic apps.
