Framework Overview
Architecture
The comprehensive lifecycle testing framework consists of several key components:
#![allow(unused)]
fn main() {
// Core Infrastructure
TestOrchestrator // Wrapper around orchestration components
StepErrorSimulator // Realistic error scenario simulation
SqlLifecycleAssertion // SQL function validation
TestScenarioBuilder // YAML template loading
// Advanced Patterns
TemplateTestRunner // Parameterized error pattern testing
ErrorPattern // Comprehensive error configuration
TaskAssertions // Task-level validation trait
StepAssertions // Step-level validation trait
}Integration Strategy
Each test follows the integrated validation pattern:
- Exercise Lifecycle: Use orchestration framework to create scenario
- Capture SQL State: Call SQL functions to get current state
- Assert Integration: Validate SQL functions return expected values
- Document Relationship: Structured tracing showing cause → effect
Core Testing Patterns
Pattern 1: Basic Lifecycle Validation
#![allow(unused)]
fn main() {
#[sqlx::test(migrator = "tasker_core::test_helpers::MIGRATOR")]
async fn test_basic_lifecycle_validation(pool: PgPool) -> Result<()> {
tracing::info!("🧪 Testing basic lifecycle progression");
// STEP 1: Exercise lifecycle using framework
let orchestrator = TestOrchestrator::new(pool.clone());
let task = orchestrator.create_simple_task("test", "basic_validation").await?;
let step = get_first_step(&pool, task.task_uuid).await?;
// STEP 2: Validate initial state
pool.assert_step_ready(step.workflow_step_uuid).await?;
// STEP 3: Execute step
let result = orchestrator.execute_step(&step, true, 1000).await?;
assert!(result.success);
// STEP 4: Validate final state
pool.assert_step_complete(step.workflow_step_uuid).await?;
tracing::info!("✅ Basic lifecycle validation complete");
Ok(())
}
}Pattern 2: Error and Retry Validation
#![allow(unused)]
fn main() {
#[sqlx::test(migrator = "tasker_core::test_helpers::MIGRATOR")]
async fn test_error_retry_validation(pool: PgPool) -> Result<()> {
tracing::info!("🔄 Testing error and retry behavior");
let orchestrator = TestOrchestrator::new(pool.clone());
let task = orchestrator.create_simple_task("test", "retry_validation").await?;
let step = get_first_step(&pool, task.task_uuid).await?;
// STEP 1: Simulate retryable error
StepErrorSimulator::simulate_execution_error(
&pool,
&step,
1 // attempt number
).await?;
// STEP 2: Validate retry behavior
pool.assert_step_retry_behavior(
step.workflow_step_uuid,
1, // expected attempts
None, // no custom backoff
true // still retry eligible
).await?;
tracing::info!("✅ Error retry validation complete");
Ok(())
}
}Pattern 3: Complex Dependency Validation
#![allow(unused)]
fn main() {
#[sqlx::test(migrator = "tasker_core::test_helpers::MIGRATOR")]
async fn test_dependency_validation(pool: PgPool) -> Result<()> {
tracing::info!("🔗 Testing dependency relationships");
let orchestrator = TestOrchestrator::new(pool.clone());
// Create diamond pattern workflow
let task = create_diamond_workflow_task(&orchestrator).await?;
let steps = get_task_steps(&pool, task.task_uuid).await?;
// Execute start step
let result = orchestrator.execute_step(&steps[0], true, 1000).await?;
assert!(result.success);
// Fail one branch
StepErrorSimulator::simulate_validation_error(
&pool,
&steps[1],
"dependency_test_error"
).await?;
// Complete other branch
let result = orchestrator.execute_step(&steps[2], true, 1000).await?;
assert!(result.success);
// Validate convergence step is blocked
pool.assert_step_blocked(steps[3].workflow_step_uuid).await?;
tracing::info!("✅ Dependency validation complete");
Ok(())
}
}Advanced Assertion Traits
TaskAssertions Trait Usage
#![allow(unused)]
fn main() {
use common::lifecycle_test_helpers::{TaskAssertions, TaskStepDistribution};
// Task completion validation
pool.assert_task_complete(task_uuid).await?;
// Task error state validation
pool.assert_task_error(task_uuid, 2).await?; // 2 error steps
// Complex step distribution validation
pool.assert_task_step_distribution(
task_uuid,
TaskStepDistribution {
total_steps: 4,
completed_steps: 2,
failed_steps: 1,
ready_steps: 0,
pending_steps: 1,
in_progress_steps: 0,
error_steps: 1,
}
).await?;
// Execution status validation
pool.assert_task_execution_status(
task_uuid,
ExecutionStatus::BlockedByFailures,
Some(RecommendedAction::HandleFailures)
).await?;
// Completion percentage validation
pool.assert_task_completion_percentage(task_uuid, 75.0, 5.0).await?;
}StepAssertions Trait Usage
#![allow(unused)]
fn main() {
use common::lifecycle_test_helpers::StepAssertions;
// Basic step state validations
pool.assert_step_ready(step_uuid).await?;
pool.assert_step_complete(step_uuid).await?;
pool.assert_step_blocked(step_uuid).await?;
// Retry behavior validation
pool.assert_step_retry_behavior(
step_uuid,
3, // expected attempts
Some(30), // custom backoff seconds
false // not retry eligible (exhausted)
).await?;
// Dependency validation
pool.assert_step_dependencies_satisfied(step_uuid, true).await?;
// State transition sequence validation
pool.assert_step_state_sequence(
step_uuid,
vec!["Pending".to_string(), "InProgress".to_string(), "Complete".to_string()]
).await?;
// Permanent failure validation
pool.assert_step_failed_permanently(step_uuid).await?;
// Waiting for retry with specific time
let retry_time = chrono::Utc::now() + chrono::Duration::seconds(60);
pool.assert_step_waiting(step_uuid, retry_time).await?;
}Template-Based Testing
ErrorPattern Configuration
#![allow(unused)]
fn main() {
use common::lifecycle_test_helpers::{ErrorPattern, TemplateTestRunner};
// Simple patterns
let success_pattern = ErrorPattern::AllSuccess;
let first_fail_pattern = ErrorPattern::FirstStepFails { retryable: true };
let last_fail_pattern = ErrorPattern::LastStepFails { permanently: false };
// Advanced patterns
let targeted_pattern = ErrorPattern::MiddleStepFails {
step_name: "process_payment".to_string(),
attempts_before_success: 3
};
let dependency_pattern = ErrorPattern::DependencyBlockage {
blocked_step: "finalize_order".to_string(),
blocking_step: "validate_payment".to_string()
};
// Custom pattern with full control
let custom_pattern = ErrorPattern::Custom {
step_configs: {
let mut configs = HashMap::new();
configs.insert("critical_step".to_string(), StepErrorConfig {
error_type: StepErrorType::ExternalServiceError,
attempts_before_success: Some(5),
custom_backoff_seconds: Some(120),
permanently_fails: false,
});
configs
}
};
}Template Runner Usage
#![allow(unused)]
fn main() {
#[sqlx::test(migrator = "tasker_core::test_helpers::MIGRATOR")]
async fn test_template_patterns(pool: PgPool) -> Result<()> {
let template_runner = TemplateTestRunner::new(pool.clone()).await?;
// Test single pattern
let summary = template_runner.run_template_with_errors(
"order_fulfillment.yaml",
ErrorPattern::FirstStepFails { retryable: true }
).await?;
assert!(summary.sql_validations_passed > 0);
assert_eq!(summary.sql_validations_failed, 0);
// Test all patterns automatically
let summaries = template_runner
.run_template_with_all_patterns("linear_workflow.yaml")
.await?;
for summary in summaries {
tracing::info!(
pattern = summary.error_pattern,
execution_time = summary.execution_time_ms,
validations = summary.sql_validations_passed,
"Pattern execution complete"
);
}
Ok(())
}
}SQL Function Integration
Direct SQL Function Testing
#![allow(unused)]
fn main() {
#[sqlx::test(migrator = "tasker_core::test_helpers::MIGRATOR")]
async fn test_direct_sql_functions(pool: PgPool) -> Result<()> {
// Test get_step_readiness_status
let step_status = sqlx::query!(
"SELECT ready_for_execution, dependencies_satisfied, retry_eligible, attempts,
backoff_request_seconds, next_retry_at
FROM get_step_readiness_status($1)",
step_uuid
)
.fetch_one(&pool)
.await?;
// Validate individual fields
assert_eq!(step_status.ready_for_execution, Some(true));
assert_eq!(step_status.dependencies_satisfied, Some(true));
assert_eq!(step_status.retry_eligible, Some(false));
assert_eq!(step_status.attempts, Some(0));
// Test get_task_execution_context

"SELECT total_steps, completed_steps, failed_steps, ready_steps,
pending_steps, in_progress_steps, error_steps,
completion_percentage, execution_status, recommended_action,
blocked_by_errors
FROM get_task_execution_context($1)",
task_uuid
)
.fetch_one(&pool)
.await?;
// Validate task aggregations
assert!(task_context.total_steps.unwrap_or(0) > 0);
assert_eq!(task_context.completed_steps, Some(0));
assert_eq!(task_context.failed_steps, Some(0));
Ok(())
}
}Integrated SQL Validation Pattern
#![allow(unused)]
fn main() {
// The standard pattern used throughout the framework
async fn validate_integrated_sql_behavior(
pool: &PgPool,
task_uuid: Uuid,
step_uuid: Uuid
) -> Result<()> {
// STEP 1: Execute lifecycle action
StepErrorSimulator::simulate_execution_error(pool, step, 2).await?;
// STEP 2: Immediately validate SQL functions
SqlLifecycleAssertion::assert_step_scenario(
pool,
task_uuid,
step_uuid,
ExpectedStepState {
state: "Error".to_string(),
ready_for_execution: false,
dependencies_satisfied: true,
retry_eligible: true,
attempts: 2,
next_retry_at: Some(calculate_expected_retry_time()),
backoff_request_seconds: None,
retry_limit: 3,
}
).await?;
// STEP 3: Document the relationship
tracing::info!(
lifecycle_action = "simulate_execution_error",
sql_result = "retry_eligible=true, attempts=2",
"✅ INTEGRATION: Lifecycle → SQL alignment verified"
);
Ok(())
}

Best Practices
1. Always Use Integrated Validation Pattern
#![allow(unused)]
fn main() {
// ✅ GOOD: Integrated lifecycle + SQL validation
async fn test_step_retry_behavior(pool: PgPool) -> Result<()> {
// Exercise lifecycle
StepErrorSimulator::simulate_execution_error(pool, step, 1).await?;
// Immediately validate SQL functions
pool.assert_step_retry_behavior(step_uuid, 1, None, true).await?;
// Document relationship
tracing::info!("✅ INTEGRATION: Retry behavior alignment verified");
Ok(())
}
// ❌ BAD: Testing SQL functions in isolation
async fn test_sql_only(pool: PgPool) -> Result<()> {
// Directly manipulating database state
sqlx::query!("UPDATE steps SET attempts = 3").execute(pool).await?;
// This doesn't prove the integration works
let status = sqlx::query!("SELECT * FROM get_step_readiness_status($1)", uuid)
.fetch_one(pool).await?;
Ok(())
}
}2. Use Structured Tracing
#![allow(unused)]
fn main() {
// ✅ GOOD: Structured tracing with context
tracing::info!(
step_uuid = %step.workflow_step_uuid,
attempts = expected_attempts,
backoff = ?expected_backoff,
retry_eligible = expected_retry_eligible,
"✅ STEP ASSERTION: Retry behavior matches expectations"
);
// ❌ BAD: Unstructured logging
println!("Step retry test passed");
}3. Test Multiple Scenarios
#![allow(unused)]
fn main() {
// ✅ GOOD: Comprehensive scenario coverage
#[sqlx::test(migrator = "tasker_core::test_helpers::MIGRATOR")]
async fn test_complete_retry_scenarios(pool: PgPool) -> Result<()> {
// Test retryable error
test_retryable_error_scenario(&pool).await?;
// Test non-retryable error
test_non_retryable_error_scenario(&pool).await?;
// Test retry exhaustion
test_retry_exhaustion_scenario(&pool).await?;
// Test custom backoff
test_custom_backoff_scenario(&pool).await?;
Ok(())
}
}4. Validate State Transitions
#![allow(unused)]
fn main() {
// ✅ GOOD: Validate complete state transition sequence
pool.assert_step_state_sequence(
step_uuid,
vec![
"Pending".to_string(),
"InProgress".to_string(),
"Error".to_string(),
"WaitingForRetry".to_string(),
"Ready".to_string(),
"Complete".to_string()
]
).await?;
}5. Use Assertion Traits for Readability
#![allow(unused)]
fn main() {
// ✅ GOOD: Clear, readable assertions
pool.assert_task_complete(task_uuid).await?;
pool.assert_step_failed_permanently(step_uuid).await?;
// ❌ BAD: Manual SQL queries everywhere
let task_status = sqlx::query!("SELECT ...").fetch_one(pool).await?;
assert_eq!(task_status.some_field, Some("Complete"));
}Troubleshooting
Common Issues
1. Assertion Failures
Error: Task 01JGJX... assertion failed: expected Complete, found Processing
// Solution: Ensure lifecycle actions complete before asserting
tokio::time::sleep(Duration::from_millis(100)).await;
pool.assert_task_complete(task_uuid).await?;
2. SQL Function Mismatches
Error: Step 01JGJX... retry assertion failed: attempts expected 2, got Some(1)
// Solution: Verify error simulator is configured correctly
StepErrorSimulator::simulate_execution_error(pool, step, 2).await?; // 2 attempts
3. State Machine Violations
Error: Cannot transition from Complete to InProgress
// Solution: Use proper orchestration framework, not direct DB manipulation
let result = orchestrator.execute_step(step, true, 1000).await?;
// Don't: sqlx::query!("UPDATE steps SET state = 'InProgress'").execute(pool).await?;
4. Template Loading Issues
Error: Template 'nonexistent.yaml' not found
// Solution: Ensure template exists in correct directory
// templates should be in tests/fixtures/task_templates/rust/
Debugging Techniques
1. Enable Detailed Tracing
RUST_LOG=debug cargo test test_name -- --nocapture
2. Inspect SQL Function Results Directly
#![allow(unused)]
fn main() {
let step_status = sqlx::query!(
"SELECT * FROM get_step_readiness_status($1)",
step_uuid
)
.fetch_one(&pool)
.await?;
tracing::debug!("Step status: {:?}", step_status);
}3. Validate Test Prerequisites
#![allow(unused)]
fn main() {
// Ensure test setup is correct
assert_eq!(steps.len(), 4, "Test requires 4 steps");
assert_eq!(task.namespace, "expected_namespace");
}4. Use Incremental Validation
#![allow(unused)]
fn main() {
// Validate after each step
orchestrator.execute_step(&step1, true, 1000).await?;
pool.assert_step_complete(step1.workflow_step_uuid).await?;
orchestrator.execute_step(&step2, false, 1000).await?;
pool.assert_step_retry_behavior(step2.workflow_step_uuid, 1, None, true).await?;
}Migration from Old Tests
Before (Direct Database Manipulation)
#![allow(unused)]
fn main() {
// ❌ OLD: Bypassing orchestration framework
async fn test_task_finalization_old(pool: PgPool) -> Result<()> {
// Direct database manipulation
sqlx::query!("UPDATE tasks SET state = 'Error'").execute(&pool).await?;
sqlx::query!("UPDATE steps SET state = 'Error'").execute(&pool).await?;
// Test SQL functions in isolation
let context = get_task_execution_context(&pool, task_uuid).await?;
assert_eq!(context.execution_status, ExecutionStatus::Error);
Ok(())
}
}After (Integrated Framework)
#![allow(unused)]
fn main() {
// ✅ NEW: Using integrated framework
#[sqlx::test(migrator = "tasker_core::test_helpers::MIGRATOR")]
async fn test_task_finalization_new(pool: PgPool) -> Result<()> {
tracing::info!("🧪 Testing task finalization with integrated approach");
// Use orchestration framework
let orchestrator = TestOrchestrator::new(pool.clone());
let task = orchestrator.create_simple_task("test", "finalization").await?;
let step = get_first_step(&pool, task.task_uuid).await?;
// Create error state through framework
StepErrorSimulator::simulate_validation_error(
&pool,
&step,
"finalization_test_error"
).await?;
// Immediately validate SQL functions
pool.assert_step_failed_permanently(step.workflow_step_uuid).await?;
pool.assert_task_error(task.task_uuid, 1).await?;
tracing::info!("✅ INTEGRATION: Finalization behavior verified");
Ok(())
}
