• Do not use union
• It is better to define PartitionProjection class and create factory methods such as PartitionProjection.Integer().
• @ throws may not be needed
• Do not import like readonly partitionProjection?: import('./partition-projection').PartitionProjection;
• Unit test for enum definition may not be essential.

describe('DateIntervalUnit', () => {
  test('has correct enum values', () => {
    expect(glue.DateIntervalUnit.YEARS).toBe('YEARS');
    expect(glue.DateIntervalUnit.MONTHS).toBe('MONTHS');
    expect(glue.DateIntervalUnit.WEEKS).toBe('WEEKS');
    expect(glue.DateIntervalUnit.DAYS).toBe('DAYS');
    expect(glue.DateIntervalUnit.HOURS).toBe('HOURS');
    expect(glue.DateIntervalUnit.MINUTES).toBe('MINUTES');
    expect(glue.DateIntervalUnit.SECONDS).toBe('SECONDS');
  });

  test('has all 7 interval units', () => {
    const values = Object.values(glue.DateIntervalUnit);
    expect(values).toHaveLength(7);
    expect(values).toContain('YEARS');
    expect(values).toContain('MONTHS');
    expect(values).toContain('WEEKS');
    expect(values).toContain('DAYS');
    expect(values).toContain('HOURS');
    expect(values).toContain('MINUTES');
    expect(values).toContain('SECONDS');
  });
});
