# Live API Integration Tests

## Overview

The sunocore library includes comprehensive integration tests that call the real SUNO_BASE_URL API. These tests validate that the new high-level search API functions work correctly against the actual backend.

## Test Location

File: `tests/integration_discover_search.rs`

## Available Tests

### 1. `test_search_with_new_ergonomic_api` ⭐ (NEW)
Tests the new high-level ergonomic search API against the real API.

**What it tests:**
- ✅ Simple public song search using `SearchRequest::simple_public_song()`
- ✅ Compound search with multiple query types using `SearchRequest::builder()`
- ✅ Filtered search with custom filters using `SearchFilters::builder()`
- ✅ Similar songs search using `SearchQuery::similar_to()`
- ✅ All API calls return valid responses
- ✅ Auto-generated names match expected format
- ✅ Query serialization works correctly

**Test source code:**
```rust
#[test]
#[ignore]
fn test_search_with_new_ergonomic_api() {
    // Test 1: Simple search
    let search_req = SearchRequest::simple_public_song("ambient")?;

    // Test 2: Compound search
    let search_req = SearchRequest::builder()
        .public_song("jazz")
        .user("artist")
        .build()?;

    // Test 3: Search with filters
    let filters = SearchFilters::builder()
        .full_song()
        .no_covers()
        .build();
    let query = SearchQuery::public_song("ambient")
        .filters(filters)
        .is_instrumental(true)
        .build()?;

    // Test 4: Similar songs
    let query = SearchQuery::similar_to("song-uuid")
        .size(10)
        .build()?;

    // All tests make real API calls and verify success
}
```

### 2. `test_search_public_songs_real_api` (Existing)
Tests the low-level API for comparison.

### 3. `test_search_users_real_api` (Existing)
Tests user search functionality.

### 4. `test_get_homepage_sections_real_api` (Existing)
Tests discover endpoint.

## Running the Tests

### Prerequisites

You need a running Suno API endpoint and credentials:

```bash
# Option 1: Local development server
export SUNO_BASE_URL="http://127.0.0.1:8000"
export SUNO_API_KEY="your-api-key-here"

# Option 2: Staging server
export SUNO_BASE_URL="https://studio-api-staging.suno.com"
export SUNO_API_KEY="your-staging-api-key"

# Option 3: Production server
export SUNO_BASE_URL="https://studio-api.suno.com"
export SUNO_API_KEY="your-production-api-key"
```

### Running Individual Tests

```bash
# Run only the new ergonomic API test
cargo nextest run --test integration_discover_search test_search_with_new_ergonomic_api -- --ignored --nocapture

# Run with output
cargo test --test integration_discover_search test_search_with_new_ergonomic_api -- --ignored --nocapture

# Run all ignored tests
cargo nextest run --test integration_discover_search -- --ignored --nocapture

# Run with test output
cargo test --test integration_discover_search -- --ignored --nocapture
```

### Example: Running Against Local Dev Server

```bash
# Terminal 1: Start your local dev server
cd /path/to/suno-api
./start-dev-server.sh

# Terminal 2: Run the tests
cd /Users/neil/suno/oxide/sunocore
export SUNO_BASE_URL="http://127.0.0.1:8000"
export SUNO_API_KEY="test-api-key"
cargo test --test integration_discover_search test_search_with_new_ergonomic_api -- --ignored --nocapture
```

## Expected Output

When running successfully, you should see:

```
=== Testing New Ergonomic Search API ===

Test 1: Simple public song search
✓ Simple search successful, found 1 queries in response

Test 2: Compound search with multiple query types
✓ Built compound request with 2 queries
✓ Compound search successful, got 2 results

Test 3: Search with filters
✓ Built filtered query with name: public_songambient
✓ Filtered search successful

Test 4: Similar songs search (requires valid song ID)
✓ Built similar song query: similar_songsong-uuid

=== All new API tests passed! ===
```

## What Gets Tested

### API Call Verification
- ✅ HTTP requests to `/api/search` endpoint
- ✅ Correct headers (Authorization, Content-Type)
- ✅ JSON serialization of queries
- ✅ Response deserialization
- ✅ HTTP status code validation

### Builder Functionality
- ✅ `SearchRequest::simple_public_song()` works
- ✅ `SearchRequest::builder()` works
- ✅ `.public_song()`, `.user()`, `.playlist()` convenience methods
- ✅ Query builder `.build()` produces valid queries
- ✅ Auto-generated names match format

### Name Auto-Generation
Verifies that names are auto-generated correctly:
- `public_song` + `ambient` → `public_songambient` ✅
- `similar_song` + `uuid` → `similar_songuuid` ✅
- `user` + `artist` → `userartist` ✅

### Serialization
- ✅ Queries serialize to correct JSON
- ✅ None fields are skipped (not serialized as null)
- ✅ All fields are present and correct

### API Response Handling
- ✅ Responses deserialize correctly
- ✅ Search results are accessible
- ✅ Query names match in response

## Common Issues & Troubleshooting

### Error: "API returned error: 401"
**Issue:** Invalid or missing API key
```bash
# Fix: Set correct API key
export SUNO_API_KEY="your-correct-api-key"
```

### Error: "Failed to send request"
**Issue:** Cannot reach the API server
```bash
# Fix: Verify server is running and reachable
curl -H "Authorization: Bearer $SUNO_API_KEY" $SUNO_BASE_URL/api/search -X POST -d '{}'
```

### Error: "env var 'SUNO_BASE_URL' not set"
**Issue:** Environment variables not exported
```bash
# Fix: Export environment variables
export SUNO_BASE_URL="http://127.0.0.1:8000"
export SUNO_API_KEY="your-api-key"

# Verify
echo $SUNO_BASE_URL
echo $SUNO_API_KEY
```

### Error: "Invalid page size"
**Issue:** Test tried to use invalid pagination
This should NOT happen with the new API because:
- Size validation happens at build time
- The test uses valid sizes (5, 10, 20)

## Test Execution Matrix

| Test | Low-Level API | New High-Level API | Real API Call |
|------|---------------|-------------------|---------------|
| `test_search_public_songs_real_api` | ✅ | ❌ | ✅ |
| `test_search_users_real_api` | ✅ | ❌ | ✅ |
| `test_search_with_new_ergonomic_api` | ❌ | ✅ | ✅ |
| `test_get_homepage_sections_real_api` | ✅ | ❌ | ✅ |

## Validations Performed

### Pre-API Call (Client-Side)
- ✅ Query name is not empty
- ✅ Required fields are present
- ✅ Page size is valid (1-100)
- ✅ JSON serialization succeeds

### API Call
- ✅ HTTP request sent with correct headers
- ✅ Authorization header included
- ✅ Content-Type set to application/json
- ✅ HTTP status code is successful (2xx)

### Post-API Call (Response Validation)
- ✅ Response body deserializes correctly
- ✅ Response structure matches expected schema
- ✅ Query names present in response
- ✅ Search results present and valid
