Real World Example

The single most valuable UI test in any e-commerce company (Flipkart, Amazon, Meesho) is the end-to-end purchase. This is the ShopEase version, using everything from this level: API setup, page objects, waits inside pages, soft assertions and a clear report.

public class CheckoutJourneyTest extends BaseTest {
    private final ShopEaseApi api = new ShopEaseApi();

    @Test(groups = {"smoke", "regression", "payments"}, description = "Search to order confirmation with COD")
    public void customerCanBuyHeadphonesWithCod() {
        TestUser user = api.createUserWithAddress(TestData.uniqueEmail("journey"), "Secret@123", "560001");
        SoftAssert soft = new SoftAssert();

        ProductPage product = new LoginPage(driver).open()
                .loginAs(user.email(), user.password())
                .header.searchFor("boat rockerz 450")
                .openResult(0);
        soft.assertEquals(product.price(), "₹1,499", "listing price");

        CheckoutPage checkout = product.addToCart().openCart().proceedToCheckout();
        soft.assertEquals(checkout.deliveryPincode(), "560001", "default address");

        OrderConfirmationPage confirmation = checkout.payWithCod();
        soft.assertTrue(confirmation.orderId().matches("ORD-\\d{6}"), "order id format");
        soft.assertEquals(confirmation.header.cartCount(), "0", "cart empty after order");

        Assert.assertEquals(api.orderStatus(confirmation.orderId()), "PLACED");  // backend agrees
        soft.assertAll();
    }
}

• Practise explaining this framework aloud: interviewers ask "walk me through your framework" in almost every SDET round.
• Add one feature yourself: wishlist page object and two tests, run them in parallel on the Docker Grid.
• Continue with the Selenium interview questions to prepare for QA automation rounds.
