Data-Driven & CI/CD — quiz

You want to test login with valid, invalid-password, locked-account, and unknown-user cases — same flow, different inputs and expected outcomes. Which TestNG mechanism fits?

• Write four near-identical `@Test` methods
• Define a `@DataProvider` returning `Object[][]` of `{username, password, expectedStatus, expectedError}`, and one `@Test(dataProvider = "loginCases")` method that drives all four
• Use `@BeforeMethod` to mutate a shared instance variable
• TestNG can't run a method with multiple inputs
