Puluvaluation

You will write two unit tests targeting the CoreStack.DefineResourcesAsync() method in the PulumiProgram project. These tests will be implemented twice: once using default Pulumi unit testing capabilities, and once using Pulumock.

Pre-requisites

• A code editor such as Rider, Visual Studio, or Visual Studio Code.
• .NET 9.0 SDK.

Understanding the Program

The PulumiProgram defines and provisions infrastructure resources. The CoreStack.DefineResourcesAsync() method performs the core logic and is the focus of testing. It does the following:

• Reads configuration values from the Stack Configuration (Pulumi.dev.yaml).
  • Uses the namespace:key: value format (e.g., azure-native:location: "swedencentral")
• Creates a Resource (ResourceGroup).
  • Takes Inputs, in this case the Location coming from Stack Configuration.
  • Returns Outputs that can be used by other components in the program.
• Exposes selected Outputs as Stack Outputs, making them accessible to other stacks.

Implementing Tests

You will work only in the Tests classes, where you will:

• Mock:
  • The Stack Configuration value for location (azure-native:location: "swedencentral")
  • The Resource Azure API version Output (ResourceGroup.AzureApiVersion)
• Run the test to simulate the deployment and capture the result.
• Assert that the inputs and outputs behave as expected.

Resources You Can Use

You're encouraged to use the internet, tools, and all provided resources to complete the task as you normally would. See relevant resources:
