Core Java into WebDriver, waits, TestNG, and a CI-integrated test suite with Page Object Model structure.
The automation curriculum opens with Core Java so that classes, collections, and exception handling are in place before browser control begins. WebDriver follows, pairing locator strategies with explicit wait conditions chosen to match each action — the Selenium documentation notes that readyState complete does not guarantee JavaScript-inserted elements exist, and warns against mixing implicit and explicit waits in one script.
TestNG organizes suites and assertions; Maven manages dependencies and the build lifecycle. Git tracks revisions while Jenkins runs the suite automatically. The Page Object Model separates page structure from test logic, Apache POI supplies data-driven rows from spreadsheets, and Cucumber/BDD expresses scenarios as Gherkin feature files. Selenium Grid and Docker extend execution across environments.
Suggested practice (grounded in the Selenium waits documentation): write a test that waits for an element inserted by JavaScript after page load. Use a single explicit condition matched to the action being performed — for example, waiting until the element is clickable before clicking — rather than a generic readyState or implicit timeout. Run the test and inspect the failure message when the condition times out: it should name the missing element and the wait condition. Keep implicit and explicit waits on separate scripts so the two mechanisms never interact.
