```
public TestTupleSchema()
```
- Method Detail
  - testRequiredFixedWidthColumn
```
public void testRequiredFixedWidthColumn()
```
    Test a fixed-width, primitive, required column. Includes basic tests common to all data types. (Basic tests are not repeated for other types.)
  - testNullableFixedWidthColumn
```
public void testNullableFixedWidthColumn()
```
  - testRepeatedFixedWidthColumn
```
public void testRepeatedFixedWidthColumn()
```
  - testRequiredVariableWidthColumn

public void testRequiredVariableWidthColumn()

  - testNullableVariableWidthColumn
```
public void testNullableVariableWidthColumn()
```
  - testRepeatedVariableWidthColumn
```
public void testRepeatedVariableWidthColumn()
```
  - testDecimalScalePrecision
```
public void testDecimalScalePrecision()
```
  - testMapColumn
```
public void testMapColumn()
```
    Tests a map column. Maps can only be required or repeated, not nullable. (But, the columns in the map can be nullable.)
  - testRepeatedMapColumn
```
public void testRepeatedMapColumn()
```
  - testUnionColumn
```
public void testUnionColumn()
```
  - testListColumn
```
public void testListColumn()
```
  - testEmptyRootTuple
```
public void testEmptyRootTuple()
```
    Test the basics of an empty root tuple (i.e. row) schema.
  - testNonEmptyRootTuple
```
public void testNonEmptyRootTuple()
```
    Test the basics of a non-empty root tuple (i.e. a row) using a pair of primitive columns.
  - testMapTupleFromMetadata
```
public void testMapTupleFromMetadata()
```
    Test a complex map schema of the form:
    a.`b.x`.`c.y`.d
    in which columns "a", "b.x" and "c.y" are maps, "b.x" and "c.y" are names that contains dots, and d is primitive. Here we build up the schema using the metadata schema, and generate a materialized field from the metadata.
