Architecture

Entry point

Test Cases

Business-readable tests that only orchestrate page/API actions and assertions — zero locators, zero waits.

javaTest Cases · example

1@Test(groups = {"regression"}, retryAnalyzer = RetryAnalyzer.class)
2public void userCanPlaceOrder() {
3    LoginPage login = new LoginPage(driver);
4    ProductsPage products = login.loginAs(user.email(), user.password());
5    CheckoutPage checkout = products.addToCart("Sauce Labs Backpack").goToCheckout();
6 
7    Assert.assertEquals(checkout.orderTotal(), "$32.39", "Order total mismatch");
8}

Best practices

One business intent per test method
Assertions live in the test, not in page classes
Data comes from a data provider or test-data factory

Common mistakes

Thread.sleep() inside tests
Locators leaking into the test layer
Tests depending on execution order

Interview question

How do you keep tests independent when they run in parallel?
