Chore: test cov

[AxiosLeo]

Note

Significantly expands unit tests across modules, adding coverage for SQL building/management, client creation/connection logic, core query execution, hooks, operators, query utilities, and transaction workflows with validations and error paths.

• Tests:
  • Builder/ManageSQLBuilder:
    • Add cases for FORCE INDEX (strings/arrays/PRIMARY) on SELECT/UPDATE.
    • Validate update/delete preconditions and error messages.
    • Subquery attrs, joins with subqueries, JSON conditions, IN/BETWEEN/CONTAIN, incrBy.
    • ManageSQL: column rendering (types, defaults, UNSIGNED, onUpdate, AFTER), create/drop index/foreign keys, references with actions, unique indexes.
  • Client:
    • Add createClient/createPromiseClient behaviors (reuse/recreate by state, named clients), input validation.
    • getClient retrieval/errors; MySQLClient types (conn/pool), execQuery, close/error handling.
    • Pool reuse/recreate logic.
  • Core:
    • _query for default/custom drivers, transaction vs non-transaction paths, queryHandler validation, error propagation.
    • _execSQL preferring query then execute, with success/error paths.
  • Hooks:
    • register/trigger, wildcard paths, special keys handling, listen integration.
  • Operator/Query:
    • find first-row behavior; error propagation including err.sql.
    • Method coverage: explain, buildSql (deprecated), inserts/updates/deletes, upsertRow, notExec.
    • QueryHandler: query, tables, deprecated upsert, existence checks, table fields.
    • Query/QueryCondition: joins (left/right/inner), having, grouping, whereConditions/groupWhere, force, keys, pagination, validations (limit/offset/join type), rich where helpers (IN/BETWEEN/LIKE/overlaps, JSON).
  • Transactions:
    • TransactionOperator suffix append; custom driver validation.
    • TransactionHandler isolation levels (full/abbr), begin/commit/rollback guards, execute/query, lastInsertId, upsert paths.
