TriggerMock class

2025-07-03

Namespace: Microsoft.Azure.Workflows.UnitTesting.Definitions

This class creates a mock instance for a trigger in a Standard logic app workflow. The TriggerMock class provides multiple ways to create mock triggers for testing Standard workflows by using static outputs, error conditions, or dynamic behavior based on execution context.

Usage

// Simple trigger mock with success status
var successTrigger = new TriggerMock(TestWorkflowStatus.Succeeded, "HttpTrigger");

// Trigger mock with specific outputs
var outputTrigger = new TriggerMock(
    TestWorkflowStatus.Succeeded,
    "EmailTrigger",
    new MockOutput { 
        Body = JToken.Parse(@"{""subject"": ""Test Email"", ""from"": ""test@example.com""}") 
    });

// Failed trigger with error information
var failedTrigger = new TriggerMock(
    TestWorkflowStatus.Failed,
    "DatabaseTrigger",
    new TestErrorInfo(
        ErrorResponseCode.ConnectionError,
        "Failed to connect to database"
    ));

// Dynamic trigger that changes behavior based on execution context
var dynamicTrigger = new TriggerMock(
    (context) => {
        var actionName = context.ActionContext.ActionName;
        
        if (actionName == "ProcessOrder") {
            return new TriggerMock(
                TestWorkflowStatus.Succeeded, 
                "OrderTrigger",
                new MockOutput { Body = JToken.Parse(@"{""orderId"": 12345}") }
            );
        }
        
        return new TriggerMock(TestWorkflowStatus.Failed, "OrderTrigger");
    },
    "ContextAwareTrigger");

Constructors

Constructor with static outputs

Creates a mock instance for TriggerMock with static outputs.

public TriggerMock(TestWorkflowStatus status, string name = null, MockOutput outputs = null)

Name	Description	Type	Required
status	The mock trigger result status	TestWorkflowStatus	Yes
name	The mock trigger name	string	No
outputs	The mock static outputs	MockOutput	No

// Example: Create a mock trigger with successful status and static outputs
var outputs = new MockOutput { 
    Body = JToken.Parse(@"{""webhookData"": ""sample payload""}")
};
var triggerMock = new TriggerMock(TestWorkflowStatus.Succeeded, "WebhookTrigger", outputs);

Constructor with error information

Creates a mock instance for TriggerMock with static error information.

public TriggerMock(TestWorkflowStatus status, string name = null, TestErrorInfo error = null)

Name	Description	Type	Required
status	The mock trigger result status	TestWorkflowStatus	Yes
name	The mock trigger name	string	No
error	The mock trigger error info	TestErrorInfo	No

// Example: Create a mock trigger with failed status and error information
var errorInfo = new TestErrorInfo(
    ErrorResponseCode.Unauthorized,
    "Authentication failed for trigger"
);
var triggerMock = new TriggerMock(TestWorkflowStatus.Failed, "SecureTrigger", errorInfo);

Constructor with callback function

Creates a mock instance for TriggerMock with a callback function for dynamic outputs.

public TriggerMock(Func<TestExecutionContext, TriggerMock> onGetTriggerMock, string name = null)

Name	Description	Type	Required
onGetTriggerMock	The callback function to get the mock trigger	Func<TestExecutionContext, TriggerMock>	Yes
name	The mock trigger name	string	No

// Example: Create a mock trigger with dynamic outputs based on execution context
var triggerMock = new TriggerMock(
    (context) => {
        var inputs = context.ActionContext.ActionInputs;
        var eventType = inputs["eventType"]?.Value<string>();
        
        // Return different mock based on event type
        if (eventType == "priority") {
            return new TriggerMock(
                TestWorkflowStatus.Succeeded, 
                "EventTrigger", 
                new MockOutput { Body = JToken.Parse(@"{""priority"": true}") }
            );
        }
        
        return new TriggerMock(TestWorkflowStatus.Succeeded, "EventTrigger");
    }, 
    "ConditionalEventTrigger");

JSON constructor

Creates a mock instance for TriggerMock from JSON.

public TriggerMock(TestWorkflowStatus status, string name = null, JToken outputs = null, TestErrorInfo error = null)

Name	Description	Type	Required
status	The mock trigger result status	TestWorkflowStatus	Yes
name	The mock trigger name	string	No
outputs	The mock outputs	MockOutput	No
error	The mock error	TestErrorInfo	No

// Example: Create a mock trigger from JSON
var triggerFromJson = JsonConvert.DeserializeObject<TriggerMock>(File.ReadAllText(mockDataPath));

Properties

Name	Description	Type	Required
Name	The name of the mock operation	string	No
Status	The operation status	TestWorkflowStatus	No
Outputs	The static output in JSON format	JToken	No
Error	The operation error	TestErrorInfo	No
