Real World — E-Commerce QA Project: An automation suite is like a "robot pilot" that records the click-type-verify steps you repeat by hand and replays them flawlessly at the pre

An automation suite is like a "robot pilot" that records the click-type-verify steps you repeat by hand and replays them flawlessly at the press of a button — like an aircraft autopilot that you program the route into once and it executes with the same precision on every flight: you code the scenario once, and the robot performs the same check tirelessly on every deploy. But if manual testing already works, why spend time on automation with Java + Selenium + JUnit5? Because on an e-commerce site with 10,000 users, manual testing means repeating the login, search, and cart flow for hours before every deploy, and tired humans skip steps; automation runs the same flow in 3 minutes without skipping. This does the same job as Python + pytest, but Java's static type safety validates Selenium API calls at compile time during a refactor in a large team, preventing errors that in Python only blow up at runtime. For a QA engineer the real gain is reliability: the automation suite validates a midnight hotfix in seconds and catches, already at the CI stage, regressions that would otherwise become production incidents in a pipeline moving too fast for manual checks.

Which default Maven lifecycle phase is used to run tests and generate test reports?

In Maven, the `mvn test` command triggers the test phase. This phase compiles test code under `src/test/java` and executes tests using the Surefire plugin to generate reports.

In the Maven structure, which lifecycle phase is responsible for compiling test files located in `src/test/java` and executing the tests via the Surefire plugin?

The `test` phase in Maven is designed to execute the project's tests. Preceding this, the `compile` and `test-compile` phases run, after which the Surefire plugin automatically processes the tests and generates reports.
