🚀 Version 1.0.0 Features (Current)

✅ No-Prefix Tera Templating (Implemented)

Create clean, readable templates with no complex namespaces:

[meta]
name = "{{ svc }}_otel_proof"
version = "1.0.0"
description = "Telemetry-only validation"

[vars]                # authoring-only; runtime ignores this table
svc = "{{ svc }}"
env = "{{ env }}"
endpoint = "{{ endpoint }}"
exporter = "{{ exporter }}"
freeze_clock = "{{ freeze_clock }}"
image = "{{ image }}"

[otel]
exporter = "{{ exporter }}"
endpoint = "{{ endpoint }}"
protocol = "http/protobuf"
sample_ratio = 1.0
resources = { "service.name" = "{{ svc }}", "env" = "{{ env }}" }

[service.clnrm]
plugin = "generic_container"
image = "{{ image }}"
args = ["self-test", "--otel-exporter", "{{ exporter }}", "--otel-endpoint", "{{ endpoint }}"]
env = { "OTEL_TRACES_EXPORTER" = "{{ exporter }}", "OTEL_EXPORTER_OTLP_ENDPOINT" = "{{ endpoint }}" }
wait_for_span = "clnrm.run"

[[scenario]]
name = "otel_only_proof"
service = "clnrm"
run = "clnrm run --otel-exporter {{ exporter }} --otel-endpoint {{ endpoint }}"
artifacts.collect = ["spans:default"]

[[expect.span]]
name = "clnrm.run"
kind = "internal"
attrs.all = { "result" = "pass" }

[[expect.span]]
name = "clnrm.step:hello_world"
parent = "clnrm.run"
kind = "internal"
events.any = ["container.start", "container.exec", "container.stop"]

[expect.graph]
must_include = [["clnrm.run", "clnrm.step:hello_world"]]
acyclic = true

[expect.status]
all = "OK"

[expect.hermeticity]
no_external_services = true
resource_attrs.must_match = { "service.name" = "{{ svc }}", "env" = "{{ env }}" }

[determinism]
seed = 42
freeze_clock = "{{ freeze_clock }}"

[report]
json = "report.json"
digest = "trace.sha256"

Rust-Based Variable Resolution

Variables are resolved in Rust with clear precedence:

  • Template variables (highest priority)
  • Environment variables (e.g., $SERVICE_NAME, $OTEL_ENDPOINT)
  • Defaults (lowest priority)

Available Variables:

  • svc - Service name (default: "clnrm")
  • env - Environment (default: "ci")
  • endpoint - OTEL endpoint (default: "http://localhost:4318")
  • exporter - OTEL exporter (default: "otlp")
  • image - Container image (default: "registry/clnrm:1.0.0")
  • freeze_clock - Deterministic time (default: "2025-01-01T00:00:00Z")
  • token - OTEL auth token (default: "")

Template Generation

# Generate OTEL validation template
clnrm template otel > my-test.clnrm.toml

# The generated template uses no-prefix variables
# Variables are resolved in Rust: template vars → ENV → defaults

📚 Documentation

🎯 Legacy v0.6.0 Features

Property-Based Testing with Fake Data

Generate test scenarios with fake data generators:

# tests/load-test.clnrm.toml.tera
{% for i in range(end=1000) %}
[[steps]]
name = "load_test_{{ i }}"
command = ["curl", "http://api:8080/users",
           "-d", '{"name":"{{ fake_name() }}","email":"{{ fake_email() }}"}']
expected_output_regex = "success"
{% endfor %}

Key Features:

  • 50+ fake data generators - UUIDs, names, emails, timestamps, IPs, etc.
  • Deterministic seeding - Reproducible tests with fake_uuid_seeded(seed=42)
  • Matrix testing - Generate all combinations of parameters
  • Property-based testing - Validate properties across generated data

Example: 1000 unique API tests generated from 10 lines of template code!

Telemetry-Only Validation (OTEL)

Prove system correctness using OpenTelemetry spans exclusively:

# tests/otel-validation.clnrm.toml
[services.otel_collector]
plugin = "otel_collector"
image = "otel/opentelemetry-collector:latest"

[services.app_under_test]
plugin = "generic_container"
image = "myapp:latest"
env.OTEL_EXPORTER_OTLP_ENDPOINT = "http://otel_collector:4318"

[[scenario]]
name = "otel_self_validation"
service = "app_under_test"
run = "myapp --otel-endpoint http://otel_collector:4318"

# Validate spans prove correct behavior
[[expect.span]]
name = "myapp.request"
kind = "server"
duration_ms = { min = 10, max = 5000 }

[[expect.span]]
name = "myapp.db_query"
parent = "myapp.request"
kind = "client"

[expect.graph]
must_include = [["myapp.request", "myapp.db_query"]]
acyclic = true

[expect.hermeticity]
no_external_services = true
resource_attrs_must_match = { "service.name" = "myapp" }

Key Features:

  • Zero flakiness - Deterministic validation across environments
  • 5-Dimensional validation - Structural, temporal, cardinality, hermeticity, attribute
  • Span validators - Existence, count, attributes, hierarchy, events, duration
  • Graph validators - Parent-child relationships and cycle detection
  • Hermeticity validators - External service detection and resource validation

Example: Framework validates itself using its own telemetry - 100% deterministic!

Advanced Validation Framework

The framework provides comprehensive validation across multiple dimensions:

  • Structural Validation - Span hierarchy and relationships
  • Temporal Validation - Execution time windows and containment
  • Cardinality Validation - Count constraints across execution paths
  • Hermeticity Validation - Isolation and contamination detection
  • Attribute Validation - Semantic metadata validation

Result: Proven correctness with zero false positives.

Fake-Green Detection (v1.0)

The Problem: Tests that report "PASS" but never actually executed code.

The Solution: OTEL-first validation with 7 independent detection layers:

# Tests must PROVE they executed by generating telemetry
[[expect.span]]
name = "container.exec"
events.any = ["container.start", "container.exec", "container.stop"]

[expect.graph]
must_include = [["test.run", "container.exec"]]

[expect.counts]
spans_total.gte = 2

[expect.status]
all = "OK"

7 Detection Layers:

  1. Lifecycle Events - Container operations generated events
  2. Span Graph - Parent-child relationships exist
  3. Span Counts - Expected number of operations occurred
  4. Temporal Ordering - Operations occurred in correct sequence
  5. Window Containment - Child operations within parent timeframes
  6. Status Validation - All operations completed successfully
  7. Hermeticity - Tests run in isolation without external dependencies

Analyze Traces:

# Run test with OTEL
clnrm run test.toml --otel-endpoint http://localhost:4318

# Validate telemetry evidence
clnrm analyze test.toml traces.json

Result:

  • ✅ PASS = Code actually executed with proof
  • ❌ FAIL = Fake-green test detected (no evidence)

🎯 What Makes This Special

Framework Self-Testing

The framework tests itself through the "eat your own dog food" principle. Every feature is validated by using the framework to test its own functionality.

Hermetic Container Testing

Unlike traditional testing frameworks, clnrm provides true hermetic testing where each test runs in completely isolated, real containers with no test interference.

Universal Test Definition

Single .clnrm.toml files can test any technology stack - databases, APIs, microservices - all through containerized execution.
