Test Engineer Skills
1. Selenium
Selenium is an open-source suite for automating browsers. Test Engineers use it to validate web apps across browsers and operating systems with language bindings like Java, Python, C#, and JavaScript.
Why It's Important
It enables fast, repeatable browser checks, cross-browser confidence, and tight CI integration so regressions surface quickly instead of surprising you late.
How to Improve Selenium Skills
Own one language binding: Get fluent in Java, Python, C#, or JavaScript and write clean, testable code.
Use Selenium 4 features: Relative locators, Selenium Manager for driver management, and modern browser APIs (e.g., WebDriver BiDi) pay off.
Master locators: Prefer stable attributes (data-test), lean CSS, and only use XPath when necessary. Keep selectors resilient to UI churn.
Tame timing: Replace sleeps with explicit waits and clear expected conditions to crush flakiness.
Adopt patterns: Page Object or Screenplay to reduce duplication, isolate UI logic, and simplify maintenance.
Scale runs: Run in parallel on Selenium Grid or browser/device farms. Tune capabilities and session reuse.
Structure tests: Use JUnit/TestNG/pytest/NUnit, tag tests, and separate smoke from full suites.
Collect artifacts: Logs, screenshots, and videos on failure make triage fast.
Keep browsers, drivers, and libraries current. Flaky tests get attention early—fix root causes, don’t hide them behind endless retries.

6. Cucumber
Cucumber supports BDD with plain-language scenarios (Gherkin). It bridges product, QA, and engineering with shared, living specifications.
Why It's Important
Readable scenarios tighten alignment with business rules and keep tests meaningful to non-engineers.
How to Improve Cucumber Skills
Clean Gherkin: One clear When, meaningful Given context, and specific Then outcomes. Avoid UI trivia in steps.
Scenario Outlines and Data Tables: Drive breadth with examples, keep steps DRY.
Hooks and tagging: Global setup/teardown and selective runs with tag expressions.
Solid architecture: Page Object or Screenplay under the hood; step defs remain thin.
Parallelization and reporting: Speed up suites and publish human-friendly results.
Regular refactors: Consolidate duplicate steps and refresh domain language with stakeholders.

7. LoadRunner
LoadRunner (OpenText) is a performance testing suite that simulates traffic and captures how systems behave under stress and scale.
Why It's Important
It proves readiness—throughput, latency, stability—before production users do.
How to Improve LoadRunner Skills
Pick the right protocol: HTTP/HTML, TruClient for browser realism, or DevWeb for modern scripting.
Parameterization and correlation: Handle dynamic values and sessions cleanly to avoid false failures.
Realistic workload models: Think times, pacing, arrival rates, and user mix that mirror reality.
Meaningful SLAs: Watch p95/p99, error rates, and saturation points. Averages hide pain.
Distributed load: Multiple generators, consistent time sync, and network baselines.
Deep analysis: Tie server metrics to client timings and trace bottlenecks to code, DB, or network.
