Works with

Suite definitions that produce smoke, regression and targeted runs without duplicating tests
Parallel execution tuned per environment, with shared-state issues resolved rather than worked around
Failure screenshots and reporting wired in through listeners, outside your test logic
Dependency configuration so one broken precondition doesn’t mask real defects

What it is

TestNG is the test runner that gives a Java automation suite its structure: annotations for setup and teardown, groups and suites for slicing what runs when, data providers for parameterised cases, and native parallel execution. Selenium and Appium handle the driving; TestNG decides what runs, in what order, and how results are reported.

How PerfectQA uses Test NG

TestNG is the execution backbone under most of our Java automation. We use it for the things it does better than the alternatives: grouping tests so a smoke set and a full regression run come from one suite definition, data providers for genuinely table-driven cases, and dependency declarations so a failed login doesn’t produce forty cascading failures that hide the one real defect. Parallel configuration is set at the suite level and tuned to the environment rather than hard-coded, because the right thread count on a developer laptop is not the right one in CI. We use listeners for reporting and screenshot capture on failure so that instrumentation lives outside the test logic. On inherited suites, the most common fix is untangling shared state between tests that were only ever run serially and now fail unpredictably under parallel execution.
