Verified comprehensive test infrastructure already exists in proxy/helpers_test.go: - MockUpstream with configurable scenarios - Test mode configuration (TestModeEnv, TestMaxRetriesEnv) - Request builders and response assertions - Proxy handler factory and execution helpers - All helper tests pass successfully No code changes needed - infrastructure is complete and functional.

# Test Infrastructure Verification (bf-3zp)
|
|
|
|
## Summary
|
|
|
|
Verified that comprehensive test infrastructure for mock upstream server already exists in `proxy/helpers_test.go`.
|
|
|
|
## Existing Infrastructure
|
|
|
|
### 1. MockUpstream Server
|
|
- `MockUpstream` struct with httptest.Server
|
|
- Configurable scenarios (429, empty body, invalid JSON, etc.)
|
|
- Request counting and failure simulation
|
|
- Custom handler support
|
|
|
|
### 2. Test Mode Configuration
|
|
- `TestModeEnv` environment variable support
|
|
- `TestMaxRetriesEnv` for fast test execution
|
|
- `ConfigureTestEnv()` helper function
|
|
- `IsTestMode()` and `GetTestMaxRetries()` functions
|
|
|
|
### 3. Test Request Builders
|
|
- `CreateProxyRequest()` - Generic request builder
|
|
- `CreateMessagesRequest()` - /v1/messages requests
|
|
- `CreateStreamingMessagesRequest()` - Streaming requests
|
|
- `CreateNonStreamingMessagesRequest()` - Non-streaming requests
|
|
|
|
### 4. Response Assertions
|
|
- `AssertStatusCode()` - Status code validation
|
|
- `AssertJSONBody()` - JSON validation
|
|
- `AssertResponseField()` - Field value checking
|
|
- `AssertEmptyBody()` - Empty body validation
|
|
- `AssertHeader()` - Header validation
|
|
- `AssertContentType()` - Content-Type validation
|
|
|
|
### 5. Proxy Handler Factory
|
|
- `CreateTestProxyHandler()` - Creates configured ProxyHandler instances
|
|
- Automatically sets test environment variables
|
|
- Configures high rate limits to avoid test interference
|
|
|
|
### 6. Test Execution Helpers
|
|
- `ExecuteProxyRequest()` - Execute request through proxy
|
|
- `ExecuteMessagesRequest()` - Execute /v1/messages request
|
|
- Response reading helpers (`ReadResponseBody`, `ReadJSONResponse`)
|
|
|
|
### 7. Duration Assertions
|
|
- `AssertDurationAtLeast()` - Minimum duration validation
|
|
- `AssertDurationInRange()` - Range validation
|
|
- `CalculateBackoffDelay()` - Backoff calculation helper
|
|
- `CalculateTotalMaxDelay()` - Total delay calculation
|
|
|
|
### 8. Mock Server Helpers
|
|
- `CreateCountingMockServer()` - Counting mock server
|
|
- `CountingMockServer` - Wraps httptest.Server with counting
|
|
|
|
### 9. Additional Helpers
|
|
- `WaitForCondition()` - Polling helper
|
|
- `AssertUpstreamCallCount()` - Request count validation
|
|
- `ResetMetrics()` - Metrics reset helper
|
|
- `CreateTestRequestBody()` - Body builder
|
|
|
|
## Verification Results
|
|
|
|
All helper tests pass:
|
|
```bash
|
|
go test ./proxy/ -run TestHelper -v
|
|
=== RUN TestHelperFunctions
|
|
--- PASS: TestHelperFunctions (0.00s)
|
|
--- PASS: TestHelperFunctions/IsTestMode (0.00s)
|
|
--- PASS: TestHelperFunctions/GetTestMaxRetries (0.00s)
|
|
--- PASS: TestHelperFunctions/CalculateBackoffDelay (0.00s)
|
|
--- PASS: TestHelperFunctions/CreateNonStreamingMessagesRequest (0.00s)
|
|
--- PASS: TestHelperFunctions/CreateStreamingMessagesRequest (0.00s)
|
|
```
|
|
|
|
Mock upstream tests pass:
|
|
```bash
|
|
go test ./proxy/ -run TestMockUpstreamBasic -v
|
|
=== RUN TestMockUpstreamBasic
|
|
--- PASS: TestMockUpstreamBasic (0.00s)
|
|
--- PASS: TestMockUpstreamBasic/success_scenario (0.00s)
|
|
--- PASS: TestMockUpstreamBasic/429_scenario (0.00s)
|
|
```
|
|
|
|
## Conclusion
|
|
|
|
The test infrastructure described in bead bf-3zp already exists and is fully functional. No new code changes are needed. The infrastructure includes:
|
|
- ✅ net/http/httptest-based mock upstream server
|
|
- ✅ Test helper functions for common setup
|
|
- ✅ Environment/test-mode flags for fast execution
|
|
- ✅ Tests never hit real api.z.ai (uses mock servers)
|
|
- ✅ All helper tests pass
