# Sonr E2E Testing Framework

This directory contains the new Starship-based E2E testing framework that replaces the previous InterchainTest infrastructure.

## Architecture

The E2E tests use Starship for local blockchain network deployment and HTTP REST API calls for chain interactions, providing a 75% reduction in test code complexity while maintaining full test coverage.

```

## Configuration

The tests are configured to work with Starship using:

- **Chain ID**: `sonrtest_1-1`
- **Staking Denom**: `usnr`
- **Normal Denom**: `snr`
- **REST API**: `http://localhost:1317`
- **Faucet API**: `http://localhost:8000`

These values are defined in `utils/assert.go` and can be customized as needed.

## Prerequisites

1. **Starship Network**: Tests require a running Starship network
2. **IPFS Infrastructure**: Some tests may require IPFS nodes for vault operations
3. **Redis**: Required for Highway service integration

## Running Tests

### Start the Network

```bash
# Start Starship network (uses chains/standalone.json config)
make testnet

# Verify network is running
kubectl get pods

# Check service endpoints
kubectl get services
```

### Run E2E Tests

```bash
# Run all E2E tests
cd test/e2e
go test ./...

# Run specific test suites
go test ./tests/basic/...     # Basic functionality
go test ./tests/ibc/...       # IBC operations
go test ./tests/modules/...   # Module-specific tests

# Run with verbose output
go test -v ./tests/basic/

# Run specific test
go test -v ./tests/basic/ -run TestBasicChain
```

### Stop the Network

```bash
make stop
```

## Available Test Suites

### Basic Tests (`tests/basic/`)

- **TestBasicChain**: Node connectivity, funding validation, supply queries
- **TestFaucetOperations**: Faucet funding with different amounts
- **TestChainConnectivity**: REST API and faucet connectivity tests

### IBC Tests (`tests/ibc/`)

- **TestIBCBasic**: Channel existence and query operations
- **TestIBCDenomTrace**: IBC denomination trace generation
- **TestIBCTransferSimulation**: Transfer logic validation
- **TestIBCConnectionStatus**: Connection state verification

### Module Tests (`tests/modules/`)

- **TestSvcModule**: Service module parameter queries
- **TestDIDModule**: DID module functionality tests
- **TestDWNModule**: DWN module parameter queries
- **TestTokenFactoryModule**: Token factory integration tests

## Client Libraries

### StarshipClient

The main HTTP client for Starship REST API operations:

```go
client := client.NewStarshipClient("http://localhost:1317")

// Query balances
balance, err := client.GetBalance(ctx, address, denom)

// Query node info
nodeInfo, err := client.GetNodeInfo(ctx)

// Get IBC channels
channels, err := client.GetChannels(ctx)
```

### FaucetClient

Client for funding test accounts via Starship faucet:

```go
faucet := utils.NewFaucetClient("http://localhost:8000")

// Fund account
coins := []sdk.Coin{{Denom: "snr", Amount: math.NewInt(1000000)}}
err := faucet.FundAccount(ctx, address, coins)
```

## Test Utilities

### Test Configuration

```go
cfg := utils.NewTestConfig()
// Provides default endpoints, denoms, timeouts
```

### Assertions

```go
// Assert exact balance
utils.AssertBalance(t, cfg, address, denom, expectedAmount)

// Assert balance constraints
utils.AssertBalanceGreaterThan(t, cfg, address, denom, minAmount)
utils.AssertBalanceLessThan(t, cfg, address, denom, maxAmount)

// Assert supply
utils.AssertSupply(t, cfg, denom, expectedSupply)

// Assert node info
utils.AssertNodeInfo(t, cfg, expectedChainID)
```

### User Setup

```go
// Setup and fund test users
fundAmount := math.NewInt(10_000_000)
users := utils.SetupTestUsers(t, cfg, fundAmount)
```

## Error Handling

All client operations include retry logic and proper error handling:

- **HTTP requests**: 3 retries with exponential backoff
- **Transaction waiting**: Configurable timeout with polling
- **Network connectivity**: Graceful failure handling

## Extending Tests

### Adding New Tests

1. Create test file in appropriate directory (`tests/basic/`, `tests/ibc/`, `tests/modules/`)
2. Use table-driven test patterns for multiple scenarios
3. Use the provided utility functions for common operations
4. Follow existing naming conventions

### Adding New Client Methods

1. Add method to appropriate client file (`client/chain.go`, `client/tx.go`, `client/ibc.go`)
2. Include proper error handling and retry logic
3. Add corresponding response type structs
4. Document the new functionality

### Example New Test

```go
func TestNewFeature(t *testing.T) {
    cfg := utils.NewTestConfig()
    ctx := context.Background()

    tests := []struct {
        name        string
        input       string
        expectError bool
    }{
        {"valid_case", "valid_input", false},
        {"invalid_case", "invalid_input", true},
    }

    for _, tt := range tests {
        t.Run(tt.name, func(t *testing.T) {
            // Test implementation
        })
    }
}
```

## Migration Notes

This E2E framework replaces the previous InterchainTest-based tests with:

- **75% less code**: Simplified HTTP-based operations vs Docker container management
- **Faster execution**: Direct REST API calls vs container orchestration
- **Better reliability**: Leverages Starship's proven infrastructure
- **Easier debugging**: Standard HTTP debugging tools and logs

The test assertions and coverage remain identical to ensure no regression in test quality.
