NoOptionalOperatorsInTests class

A lint rule that forbids using optional operators (?., ??) in test files.

This rule flags optional operators in test blocks to ensure tests fail explicitly at the point of failure rather than silently handling nulls.

Example of code that triggers this rule:

test('example', () {
  final result = someObject?.someProperty;  // LINT
  final value = someValue ?? defaultValue;  // LINT
});

Example of code that doesn't trigger this rule:

test('example', () {
  expect(someObject, isNotNull);
  final result = someObject.someProperty;
  expect(someValue, isNotNull);
  final value = someValue;
  final assertion = someValue!;  // This is fine
});
