Cisco Pyats -- Network Test and Automation Solution: Data-Driven and Reusable Testing for Modern Networks

解鎖自動化網路測試的力量，使用 Cisco pyATS 框架。

由業界專家 John Capobianco 和 Dan Wade 撰寫的《Cisco pyATS--網路測試與自動化解決方案》是一本全面介紹 Cisco pyATS 框架的指南，這是一個基於 Python 的網路測試、設備配置、解析、API 和平行程式設計的環境。

Capobianco 和 Wade 深入探討了 pyATS 及其庫（Genie）的廣泛功能。您將學習如何利用 pyATS 進行網路測試，包括軟體版本測試、介面測試、鄰居測試和可達性測試。您將發現如何生成基於意圖的配置、創建模擬設備，並使用 CI/CD 管道和人工智慧將 pyATS 整合到更大的工作流程中。您將探索 pyATS Blitz 功能，這引入了一種低代碼無代碼的網路測試方法，允許您使用 YAML 配置設備和編寫測試案例，類似於 Ansible。您還將學習如何在測試期間或之後使用 pyATS Clean 功能重置設備，從頭開始構建 pyATS 映像以進行容器化應用程式部署，以及更多內容。

無論您是網路專業人士、軟體開發人員，還是準備參加 Cisco DevNet 專家實驗室考試，這本書都是必備資源。
