Modifier and Type	Method and Description
`static void`	`setUpConnection()`
`static void`	`tearDownConnection()`
`void`	`testEmptyJsonFileDoesntSuppressNetSchema1()` Tests that an empty JSON file (having zero records) no longer triggers breakage in schema propagation.
`void`	`testEmptyJsonFileDoesntSuppressNetSchema2()`
`void`	`testGetTablesZeroRowsByTableSchemaOrNameWorks()` (Failed before (because table schema and name tests are pushed down).)
`void`	`testInfoSchemaTablesZeroRowsBy_TABLE_CATALOG_works()` (Worked before (because TABLE_CATALOG test not pushed down).)
`void`	`testInfoSchemaTablesZeroRowsBy_TABLE_NAME_works()` (Failed before (because TABLE_NAME test is pushed down).)
`void`	`testInfoSchemaTablesZeroRowsBy_TABLE_SCHEMA_works()` Tests that an INFORMATION_SCHEMA.TABLES query that has zero rows because of a (simple-enough) filter expression using column TABLE_SCHEMA (which supports pushdown) still has all columns.
`void`	`testInfoSchemaTablesZeroRowsByLimitWorks()` (Worked before.)
`void`	`testInfoSchemaTablesZeroRowsByWhereFalseWorks()` (Worked before.)
