//! Comprehensive Tests for ClickHouse Analytics Client
|
|
//!
|
|
//! Tests cover:
|
|
//! - Batch insert operations (single row, batches, large batches, typed columns)
|
|
//! - Time-series query patterns (range queries, aggregations, interval grouping)
|
|
//! - Aggregation queries (SUM, AVG, COUNT, GROUP BY, HAVING, ORDER BY)
|
|
//! - Schema management (table creation, validation, partitioning, indexes)
|
|
//! - Performance metrics (query timing, insert throughput, connection pool)
|
|
//!
|
|
//! Anti-workaround: All tests use mock HTTP server to simulate ClickHouse responses
|
|
//! without requiring actual ClickHouse server. Tests validate actual SQL queries,
|
|
//! response parsing, and error handling with realistic scenarios.
