# Validation Functions Examples

# Example 1: Validate login response structure

  # Check version format

# Example 2: Validate user list response

  # Check response structure

  # Check meta has pagination
  assert_json_field "$response" ".meta.page" || return 1

# Example 3: Validate user creation response

# Example 4: Validate specific field values

  # Check user has permissions

# Example 5: Validate error response

# Example 6: Validate pagination metadata

  # Check pagination values
