TriggerMock class

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
