How do I test validation functions in my code?

You can test validation functions by writing unit tests that cover various input scenarios. What specific validation are you working on?

I'm working on a function that checks if an email is valid.

Great! You can create test cases with valid emails, invalid emails, and edge cases like empty strings. Would you like an example?

Yes, please provide an example of the test cases.

Sure! You can use a testing framework like Jest. Here’s a simple example:

test('valid email', () => {
  expect(isValidEmail('[email protected]')).toBe(true);
});

test('invalid email', () => {
  expect(isValidEmail('[email protected]')).toBe(false);
});
