Tell me about testing. Do you participate in automated tests or manual testing?

I actively participate in testing, including writing automated tests and conducting manual testing when necessary.

Automated tests:

• Write unit tests to verify individual components and methods.
• Use integration tests to check interactions between modules.
• Set up test environments and CI/CD for automatic test execution.

Manual testing:

• Used to verify complex scenarios that are difficult to cover with automated tests.
• Used when testing UI or investigating bugs.

Example in Java using JUnit:

@Test
public void testCalculateDiscount() {
    PromoService promoService = new PromoService();
    double discount = promoService.calculateDiscount("SUMMER2024", 1000);
    assertEquals(100, discount, 0.01);
}

Thus, testing is an integral part of development, and I strive to cover the code as comprehensively as possible, combining different approaches.
