Architecture & Sessions (Appium 2.x, W3C)
* **Client–Server model** – WebDriver protocol, stateless commands, HTTP lifecycle. * **Appium 2.x modularity** – server vs drivers vs plugins; versioning and compatibility. * **Session lifecycle** – create → use → delete; idempotency; stale session handling. * **W3C spec essentials** – endpoints, capabilities schema, `alwaysMatch`/`firstMatch`. * **Command routing** – how the server routes to drivers / plugins. * **Transport & concurrency** – parallel sessions, port management, isolation. * **Security & permissions (generic)** – server exposure, allowing origins, safe configs. * **Error taxonomy** – WebDriver error codes vs driver-specific messages; retryability. > AI hints: “diagnose session creation failure given logs”, “identify where a command is processed”, “choose the correct component to upgrade (server vs driver vs plugin).”
Capabilities & Drivers/Plugins (cross-platform concepts)
* **W3C capability structure** – `capabilities: { alwaysMatch, firstMatch }`. * **Cross-platform core keys** – `platformName`, `automationName`, `app` **or** `browserName`, `newCommandTimeout`. * **Vendor prefixes** – `appium:` namespacing, why it matters. * **Driver selection** – choosing the right driver via capabilities (conceptual, not OS-specific). * **Capability negotiation** – merging `alwaysMatch` with `firstMatch`. * **Profiles & reuse** – composing caps for environments (local/grid/cloud). * **Negative testing** – unsupported caps, unknown driver errors, graceful fallbacks. * **Plugins (conceptual)** – enabling features at server start vs via caps. > AI hints: “rewrite legacy JSON caps to W3C”, “decide where to place custom keys”, “explain a ‘NoSuchDriver’ error and remedy.”
Locators & Accessibility (id, xpath, platform-agnostic)
* **Locator hierarchy** – accessibility id, id/resource-id, name/label, class/type, XPath. * **Choosing robust selectors** – stability > speed; avoiding brittle index-based XPath. * **Accessibility contracts** – collaborating with devs to add unique a11y identifiers. * **Attributes & state** – enabled/visible/clickable/readable. * **Dynamic UI** – stable anchors, partial matches (where safe), fallbacks. * **Image locators (concept)** – when/why to use; limits & flakiness trade-offs. * **Locator validation** – verifying with Inspector; minimizing DOM walking. > AI hints: “pick the most resilient locator for a changing list,” “explain why a11y IDs beat text XPath,” “debug stale element reference.”
Synchronization & Stability (waits, retries, flakiness)
* **Implicit vs explicit waits** – scope, side effects, recommended defaults. * **Explicit conditions** – presence/visibility/clickability; custom conditions. * **Polling & timeouts** – reasonable values, test runtime impact. * **Race conditions** – transitions, spinners, animations; disable/await patterns. * **Idempotent steps** – safe re-clicks, verifying state before action. * **Retry strategies** – per-step vs per-test; when retries mask defects. * **Data & environment readiness** – preconditions, seeds, test isolation. > AI hints: “replace `sleep` with explicit wait logic,” “choose wait strategy for animated screens,” “identify anti-patterns that cause flakiness.”
Gestures & W3C Actions (tap, press, swipe, multi-touch)
* **W3C Actions model** – pointer types, sequences, durations. * **Viewport-relative gestures** – %-based start/end; device-agnostic math. * **Scroll vs swipe semantics** – when to use which; pagination patterns. * **Long-press & drag-and-drop** – chaining actions reliably. * **Edge cases** – off-screen elements, inertia, velocity tuning. * **Testing gestures** – verifying with screenshots/logs; avoiding magic numbers. > AI hints: “author a %-based swipe,” “convert deprecated TouchAction to W3C Actions,” “fix flaky drag-and-drop.”
Contexts & WebViews (NATIVE\_APP ↔ WEBVIEW, hybrid)
* **Context awareness** – listing contexts; switching rules. * **Element scope by context** – native vs web locator strategies (CSS/XPath in WEBVIEW). * **Timing** – waiting for WEBVIEW to appear; readiness checks. * **Context loss & recovery** – fallbacks when a view reloads. * **Cookies/storage (concept)** – manipulating state in WEBVIEW context. * **Mixed flows** – safely hopping between native and web within one test. > AI hints: “diagnose why web elements aren’t found,” “write steps to switch, act, and switch back,” “handle a disappearing WEBVIEW.”
Test Design & Structure (POM, data setup, idempotence)
* **Abstraction layers** – Screen/Page Objects, services, utilities. * **Single-responsibility tests** – crisp assertions; minimal steps per test. * **Data-driven & fixtures** – input matrices, reusable seeds. * **Selector centralization** – one source of truth for locators per screen. * **Resilience patterns** – verify → act → verify; guard clauses. * **Maintainability** – naming, reuse, avoiding copy-paste across platforms. * **Determinism** – isolation from network/test data drift. > AI hints: “refactor a long journey into maintainable screens,” “choose what belongs in the Screen Object vs the test,” “make a test rerunnable.”
Parallelism & Grids/Device Clouds (local/grid/cloud parity)
* **Concurrency model** – unique sessions, ports, temp dirs, log files. * **Capability partitioning** – routing tests to nodes via caps/labels. * **Test sharding** – splitting safely; order independence. * **Environment parity** – local vs grid vs cloud: what must stay identical. * **Resource contention** – avoiding shared state, exclusive artifacts. * **Stability in scale** – timeouts per node; monitoring saturation. * **Artifacts** – per-session logs, videos, screenshots; naming conventions. > AI hints: “configure tests to avoid session collisions,” “design sharding for 10 devices,” “explain why runs pass locally but fail on cloud.”
Debugging & Logs (server/client logs, inspector, devtools)
* **Log sources** – Appium server (debug), client logs, device/system logs. * **Reading server logs** – session start, capabilities echo, command traces. * **Common failures** – no route, element not found, stale sessions, timeouts. * **Minimal repros** – shrinking to a failing step; isolating layers. * **Inspector usage** – validate hierarchy, attributes, trial locators. * **Evidence packs** – screenshots, videos, HARs (where available), timestamps. * **Triage workflow** – classify infra vs test vs app defects. > AI hints: “given a log snippet, identify root cause category,” “choose the next artifact to collect,” “improve logs to speed up RCA.”
CI/CD & Reporting (headless labs, retries, flaky quarantine)
* **Pipelines** – triggering, environment setup, caching dependencies. * **Test selection** – tags/suites, smoke vs regression, risk-based gating. * **Retry policy** – when/where to retry; max attempts; quarantining flaky tests. * **Reporting** – aggregating logs, screenshots, video, JUnit/Allure outputs. * **Quality gates** – thresholds, trend tracking, SLAs. * **Secrets & config** – safe handling of app paths, creds, URLs. * **Change safety** – canary runs, blue/green test environments. > AI hints: “design a pipeline step order,” “decide which failures qualify for auto-retry,” “specify artifacts to attach for every failure.”
