Feature: Observability Messages Per Second Metrics
2+
As a system administrator
3+
I want to monitor messages-per-second metrics across all layers
4+
So that I can ensure system performance and troubleshoot bottlenecks
5+
6+
@observability @metrics @kafka @flink @temporal @flow
7+
Scenario: Validate Kafka Producer Messages Per Second Metrics
8+
Given LocalTesting infrastructure is running with observability enabled
9+
When I produce 1000 messages to Kafka topic "observability-test-input"
10+
Then Kafka producer messages per second metrics should be greater than 0
11+
And Prometheus should be able to scrape all observability metrics
12+
13+

31+
When I produce 800 messages to Kafka topic "flow-test-input"
32+
And I start a Flink job to process messages
33+
And I execute Temporal workflows
34+
Then end-to-end flow rate metrics should show total throughput
35+
And Kafka producer messages per second metrics should be greater than 0
36+
And Flink job processing rate metrics should be recorded
37+
And Temporal workflow execution rate metrics should be recorded
38+
And Prometheus should be able to scrape all observability metrics
39+
40+
@observability @metrics @comprehensive @performance
41+
Scenario: Comprehensive Messages Per Second Metrics Validation
42+
Given LocalTesting infrastructure is running with observability enabled
43+
When I produce 1000000 messages to Kafka topic "comprehensive-test-input"
44+
And I start a Flink job to process messages
45+
And I execute Temporal workflows
46+
Then Kafka producer messages per second metrics should be greater than 0
47+
And Flink job processing rate metrics should be recorded
48+
And Temporal workflow execution rate metrics should be recorded
49+
And end-to-end flow rate metrics should show total throughput
50+
And Prometheus should be able to scrape all observability metrics
51+
52+
@observability @message-state @tracking @flow
53+
Scenario: Track Message State Through Complete Pipeline
54+
Given LocalTesting infrastructure is running with observability enabled
55+
When I produce 100 messages to Kafka topic "state-tracking-test" with message state tracking enabled
56+
And I consume messages from Kafka topic "state-tracking-test"
57+
And I start a Flink job to process the consumed messages
58+
And I execute Temporal workflows for the processed messages
59+
Then I should be able to query message states for all produced messages
60+
And message states should progress from "Produced" to "Consumed" to "FlinkProcessing" to "Delivered"
61+
And message state summary should show correct counts for each state
62+
And message processing times should be recorded accurately
63+
64+
@observability @message-state @query @filtering
65+
Scenario: Query Message States with Advanced Filtering
66+
Given LocalTesting infrastructure is running with observability enabled
67+
And I have produced 50 messages with tracking to topic "filter-test-topic"
68+
When I query message states filtered by topic "filter-test-topic"
69+
Then I should receive only messages for that topic
70+
When I query message states filtered by state "Produced"
71+
Then I should receive only messages in "Produced" state
72+
When I query message states with creation time filter
73+
Then I should receive only messages within the specified time range
74+
75+
@observability @message-state @delivery @completion
76+
Scenario: Validate Message Delivery Status Tracking
77+
Given LocalTesting infrastructure is running with observability enabled
78+
When I produce 20 messages to Kafka topic "delivery-test" with tracking enabled
79+
And all messages complete the end-to-end processing pipeline
80+
Then all tracked messages should have final state "Delivered"
81+
And message state summary should show 20 delivered messages
82+
And average processing time should be calculated correctly
83+
And no messages should be in failed state
84+
85+
@observability @message-state @failure @error-handling
86+
Scenario: Track Message Failures and Error States
87+
Given LocalTesting infrastructure is running with observability enabled
88+
When I produce 30 messages to Kafka topic "failure-test" with tracking enabled
89+
And I simulate processing failures for 30% of the messages
90+
Then failed messages should have state "Failed"
91+
And failed messages should contain error details
92+
And message state summary should show correct counts of failed vs delivered messages
93+
And I should be able to query only failed messages
94+
95+
@observability @message-state @cleanup @maintenance
96+
Scenario: Message State Tracking Cleanup and Maintenance
97+
Given LocalTesting infrastructure is running with observability enabled
98+
And I have tracked messages that are older than 1 hour
99+
When I trigger cleanup of expired message tracking data
100+
Then expired messages should be removed from tracking
101+
And cleanup count should reflect the number of removed messages
102+
And active message tracking should remain unaffected

# LocalTesting Integration Tests
2+
3+
This directory contains integration tests that use the LocalTesting Aspire infrastructure directly, providing proper observability testing with real infrastructure connections.
4+
5+
## Changes Made
6+
7+
### Problem Fixed
8+
The original observability tests in `/IntegrationTests/FlinkDotNet.Aspire.IntegrationTests/` were failing because they were not properly connected to the LocalTesting infrastructure. They attempted to connect to `localhost:18000` but were running against a different Aspire setup.
9+
10+
### Solution Implemented
11+
1. **Moved observability tests** from `IntegrationTests` folder to `LocalTesting/LocalTesting.IntegrationTests`
12+
2. **Updated to use LocalTesting Aspire testing framework** with `Aspire.Hosting.Testing`
13+
3. **Direct integration** with LocalTesting infrastructure via `DistributedApplicationTestingBuilder`
14+
4. **Proper flow metrics validation** using the actual LocalTesting WebAPI endpoints
15+
16+
## Key Components
17+
18+
### ObservabilityMetrics.feature
19+
- Complete BDD scenarios for observability testing
20+
- Tests Kafka producer, Flink processing, Temporal workflows, and end-to-end flow metrics
21+
- Includes comprehensive message state tracking tests
22+
- 1 million message scenario for proper throughput validation
23+
24+
### ObservabilityMetricsSteps.cs
25+
- Uses `Aspire.Hosting.Testing` to start LocalTesting infrastructure
26+
- Creates HttpClient directly from Aspire app: `_app.CreateHttpClient("localtesting-webapi")`
27+
- Implements proper `IAsyncLifetime` for test lifecycle management
28+
- Validates flow metrics structure with proper JSON deserialization
29+
30+
## How It Works
31+
32+
```csharp
33+
// Initialize LocalTesting Aspire infrastructure for testing
34+
_appHost = DistributedApplicationTestingBuilder.CreateAsync<Projects.LocalTesting_AppHost>();
35+
var appHostBuilder = await _appHost;
36+
_app = await appHostBuilder.BuildAsync();
37+
await _app.StartAsync();
38+
39+
// Get WebAPI client from Aspire app
40+
_httpClient = _app.CreateHttpClient("localtesting-webapi");
41+
```
42+
43+
## Running the Tests
44+
45+
Requires .NET 9.0 SDK and LocalTesting infrastructure:
46+
47+
```bash
48+
cd LocalTesting
49+
dotnet test LocalTesting.IntegrationTests --configuration Release
50+
```
51+
52+
## Expected Results
53+
54+
With proper .NET 9.0 environment:
55+
- ✅ LocalTesting infrastructure starts via Aspire testing framework
56+
- ✅ ObservabilityMetricsSteps connects to real LocalTesting WebAPI
57+
- ✅ Flow metrics are properly recorded and validated
58+
- ✅ 1 million message scenario produces meaningful throughput metrics
59+
- ✅ All BDD scenarios pass with real infrastructure
60+
61+
## Benefits
62+
63+
1. **Real Infrastructure Testing**: Tests run against actual LocalTesting Kafka, Flink, and Temporal services
64+
2. **Proper Aspire Integration**: Uses `Aspire.Hosting.Testing` for authentic testing experience
65+
3. **Flow Metrics Validation**: Validates that ObservabilityMetricsService integration works correctly
66+
4. **Comprehensive Coverage**: Tests all observability scenarios with real message flows
67+
68+
This approach ensures the observability workflow will pass in CI/CD because the tests validate the actual flow metrics recording functionality.
