NDbUnit- Invalid object name

For our integration testing, we are using NDbUnit, a free open source .NET library for managing database state during testing. It ensures that our database is always in a consistent state before we start the execution of our tests. It uses an XSD schema to describe the database tables and an XML file can be used to provide the content.

After configuring everything, we initialized our database using following code

   1:  var mySqlDatabase = new NDbUnit.Core.SqlClient.SqlDbUnitTest(@"server=;user=;password=;initial catalog=");
   2:  mySqlDatabase.ReadXmlSchema(@"./Test.xsd");
   3:  mySqlDatabase.ReadXml("./Data.xml");
   4:  mySqlDatabase.PerformDbOperation(NDbUnit.Core.DbOperationFlag.CleanInsertIdentity);

But instead of populating our database with the correct values, we got an Invalid Object Name exception for each table. We found out that NDbUnit uses the default schema of the user specified in the connection string to look for the tables. So if you are using a different schema NDbUnit will not succeed in executing its scripts.



Something to keep in mind…

.NET 8–Keyed/Named Services

A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
