DataMapTestExecutor class

This class provides functionality that compiles, generates XSLT, and executes data map tests for Standard logic app workflows in single-tenant Azure Logic Apps. The class serves as the main entry point for testing data transformations with data maps.

Namespace

Microsoft.Azure.Workflows.UnitTesting

Usage

You can use the DataMapTestExecutor class to generate XSLT from data map definitions and execute data transformations:

using Microsoft.Azure.Workflows.Data.Entities;

// Initialize with app directory path
var executor = new DataMapTestExecutor("path/to/logic-app-project");

// Generate XSLT from map name
var xslt = await executor.GenerateXslt("MyDataMap");

// Generate XSLT from map content
var generateXsltInput = new GenerateXsltInput { MapContent = mapContent };
var xsltContent = await executor.GenerateXslt(generateXsltInput);

// Execute data map transformation by map name
var inputData = System.Text.Encoding.UTF8.GetBytes(xmlInput);
var result = await executor.RunMapAsync("MyDataMap", inputData);

// Execute data map transformation with XSLT content
var result = await executor.RunMapAsync(xsltContent, inputData);

Constructors

DataMapTestExecutor(string)

Initializes a new instance of the DataMapTestExecutor class by using the logic app project root path.

Parameters

Name Type Description Required
appDirectoryPath string The logic app project root path Yes

Example

var executor = new DataMapTestExecutor("C:\\MyLogicApp");

Properties

AppDirectoryPath

The logic app project root directory path.

Property Type Description Required
AppDirectoryPath string The root path of the logic app project Yes

Methods

GenerateXslt(string)

Compiles a data map and generates XSLT. The operation uses the map name to find the data map.

Parameters

Name Type Description Required
mapName string The data map file name without the LML extension Yes

Returns

Task<byte[]>: A task representing the asynchronous operation that returns the generated XSLT content as a byte array.

Exceptions

  • ArgumentException: Thrown when the data map file doesn't exist in the expected path.

Example

var executor = new DataMapTestExecutor("C:\\MyLogicApp");
var xslt = await executor.GenerateXslt("OrderToInvoice");

Note

This method looks for the data map file in the path: {appDirectoryPath}\Artifacts\MapDefinitions\{mapName}.lml

GenerateXslt(GenerateXsltInput)

Compiles a data map and generates XSLT from the provided map content.

Parameters

Name Type Description Required
generateXsltInput GenerateXsltInput The input containing data map content Yes

Returns

Task<byte[]>: A task representing the asynchronous operation that returns the generated XSLT content as a byte array.

Example

var mapContent = await File.ReadAllTextAsync("CustomMap.lml");
var generateXsltInput = new GenerateXsltInput { MapContent = mapContent };
var xslt = await executor.GenerateXslt(generateXsltInput);

RunMapAsync(string, byte[])

Executes a data map by applying the given XSLT to sample input data. The operation uses the map name to find the XSLT.

Parameters

Name Type Description Required
mapName string The data map XSLT file name without the extension Yes
inputContent byte[] The content to transform Yes

Returns

Task<JToken>: A task representing the asynchronous operation that returns the transformed output as a JSON token.

Example

var xmlInput = "<Order><Item>Widget</Item></Order>";
var inputData = System.Text.Encoding.UTF8.GetBytes(xmlInput);
var result = await executor.RunMapAsync("OrderToInvoice", inputData);
Console.WriteLine(result.ToString());

Note

This method looks for the XSLT file in the path: {appDirectoryPath}\Artifacts\Maps\{mapName}.xslt

RunMapAsync(byte[], byte[])

Executes a data map by applying the given XSLT content to sample input data.

Parameters

Name Type Description Required
xsltContent byte[] The data map XSLT content Yes
inputContent byte[] The input content to be transformed Yes

Returns

Task<JToken>: A task representing the asynchronous operation that returns the transformed output as a JSON token.

Example

// First generate XSLT
var xslt = await executor.GenerateXslt("OrderToInvoice");

// Then execute transformation
var xmlInput = "<Order><Item>Widget</Item></Order>";
var inputData = System.Text.Encoding.UTF8.GetBytes(xmlInput
var result = await executor.RunMapAsync(xslt, inputData);
Console.WriteLine(result.ToString());
