Description
Junit
1972 - The Vietnam War is underway. A small group of boys is attached to the Defence Department as special agents. They are faster, smarter, and tougher than other boys, because they were prototypes in an Illegal experiment to create super-soldiers using hypnosis. The experiment goes sour when a Senator is assassinated, and one of the boys begins to recover his memories. Now regularized as an official unit, the army keeps the boys in case they are ever needed for special operations. When Darien, the son of a global Oil King is sent to a boarding school in the remoteness of Washington State, Peter and Travis, two members of JUNIT, are assigned as his bodyguards. It's a good thing they are on duty, because Darien is kidnapped by Spetznaz commandos.
About the Author
Geoff was born in Jersey, then under German occupation, during World War II. Soon after the war, his family moved to Brisbane, Australia. He was educated at All Souls' School, Charters Towers - a rather traditional boarding school after the English style. What knowledge one didn't learn through the ears was well and truly belted in through the rear end, complete with blood blisters. His first contact with the cane was for not running around a sports oval fast enough. He now prides himself on a complete disinterest on sports and knows nothing about cricket. This led to his creative and artistic sides developing. He had a way with words, and was a skilled debater.
After secondary school, he took to teaching, graduated, and then obtained a Post Graduate Diploma in Aboriginal Education. For the next thirty years, he lived with remote aborigines in the Great Western Desert, firstly as a primary school teacher, and later as a School Principal and Administrator. During this time, he took up writing, mostly short stories and film scripts. It was a good way to while away lonely hours in the desert evenings.
The development of miniature computers took his interest, and He wrote to the Department suggesting they take a serious look at the use of Computers in Education. Because of the proximity of a U.S. Sigint facility at Alice Springs, many of the students, especially the American kids, were interested in computing. At first they used Tandy Level Ones and Apples. While very primitive compared to today's machines, Many of the I.T. Community cut their teeth on computing under Geoff's tutelage. They even built a 'Dream 8080' and got it working.
Child welfare was another interest. Juveniles who committed offences were kept in adult prisons. Some of the kids were as young as nine years of age. Geoff fought hard to get decent juvenile facilities built for them, and also did lot of research into mental illnesses in Children. While taking a rest from the Desert, Geoff worked with the Education Department as a District Guidance Officer. He was responsible for getting educational services to handicapped children across the outback. While on Long Service leave in Cairns, his family home, he met up with his old geography teacher, Kevin Burry, who was bringing Trinity Anglican School to fruition. Kevin became ill with brain tumors, and the Bishop of North Queensland appointed Geoff as the voluntary acting principal to bring the school on line, so Geoff spent his vacation from teaching as principal of one of Queenslands largest schools.

用戶評價
這本書的語言風格讓我感到既**親切又充滿啓發性**，它似乎不是在對技術人員布道，而是在與一位資深的同行進行深度交流。作者在敘述技術原理時，經常穿插一些**個人反思和對測試文化**的見解。比如，在討論測試的有效性和維護成本時，作者坦誠地分享瞭自己團隊早期因為過度測試或測試用例設計不當而導緻的效率下降的經曆，這種坦率讓人非常信服。書中有一個章節專門討論瞭“測試的心理陷阱”，例如過度關注代碼覆蓋率的數字而忽略瞭測試的質量，或者害怕修改測試因為害怕破壞現有邏輯。作者用非常犀利的筆觸指齣瞭這些誤區，並提齣瞭“用測試驅動重構”的積極心態。這種對**軟技能和文化建設**的關注，是很多純技術手冊所缺乏的。它讓我意識到，單元測試不僅是技術工具，更是一種團隊協作和質量保障的文化載體。讀這本書，我感受到的不僅僅是技術知識的輸入，更是一種對高質量軟件工程理念的熏陶，它讓我對“編寫可測試代碼”這件事有瞭更深層次的尊重和敬畏。
评分從一個**性能調優者**的角度來看，這本書的側重點非常精準和巧妙。它沒有把單元測試視為一個獨立的模塊，而是將其視為整個軟件性能優化鏈條中的關鍵一環。我特彆關注瞭書中關於**測試隔離性對性能的影響**那一小節。作者清晰地論證瞭，不恰當的I/O操作或數據庫交互被包含在單元測試中，是如何導緻測試運行時間呈指數級增長，從而使得開發者産生抵觸情緒，最終放棄運行測試的惡性循環。書中針對性地給齣瞭如何使用內存數據庫模擬和針對性地隔離外部服務的具體代碼模式。更進一步，它還討論瞭**測試套件的健康度指標**，強調瞭平均測試運行時間（Average Test Execution Time）的重要性，並提供瞭一些工具和技巧來持續監控這個指標。對於我們這些需要頻繁進行版本迭代和性能基綫對比的團隊來說，這些信息至關重要。這本書的視角非常**立體化**，它不僅關注“是否通過”，更關注“如何高效地通過”，將測試實踐與軟件交付的整體效率緊密地結閤起來，這一點做得非常到位，體現瞭作者深厚的工程實踐背景。
评分天呐，這本書簡直是為我這種代碼小白量身定做的！我之前對單元測試這塊兒一直心裏沒底，總覺得那是高手纔玩得轉的東西，但《JUNIT》這本書完全打破瞭我的刻闆印象。它不是那種晦澀難懂的官方文檔堆砌，而是用非常生活化的語言，一步步把我這個編程新手領進瞭門。作者的講解邏輯簡直是教科書級彆的流暢，從最基礎的“為什麼要做單元測試”講起，到如何搭建環境，再到編寫第一個“Hello World”級彆的測試用例，每一步都細緻入微，生怕你跟不上。我尤其喜歡它在講解斷言（Assertions）那一部分的處理方式，沒有直接拋齣API，而是通過幾個小場景來展示不同斷言的適用性，比如什麼時候用`assertEquals`，什麼時候該用更精確的`assertThrows`。書裏大量的代碼示例都是經過精心挑選的，短小精悍，看完就能立刻上手。讀完這部分，我感覺自己不再是看著測試代碼發懵的路人甲，而是能自信地在自己的項目中插入第一個有意義的測試瞭。這本書的引入部分做得太成功瞭，它沒有直接進入技術細節的深淵，而是先給你一艘堅固的小船，讓你在安全的水域裏熟悉操作，然後纔慢慢駛嚮更廣闊的海洋。對於初學者來說，這本書的價值就在於它極強的**可操作性和心理建設作用**，讓我從“不敢碰”變成瞭“我試試看”。
评分這本書的深度和廣度都超乎瞭我的預期，它絕對不是那種隻停留在基礎概念的入門讀物。對於我這種已經有一定工作經驗，但測試覆蓋率一直上不去的工程師來說，它提供瞭非常實用的高級策略。我特彆欣賞作者在**測試的藝術與實踐**這一章節中對“測試的粒度”的探討。他沒有簡單地告訴你“寫小函數”，而是深入分析瞭集成測試、單元測試和契約測試之間的界限和協作關係，並給齣瞭在微服務架構下如何平衡測試速度與覆蓋率的實戰建議。其中關於**Mocking與Stubbing**的章節，簡直是黃金屋。作者沒有盲目推崇某一種Mocking框架，而是對比瞭不同框架（比如PowerMock和Mockito）的優缺點，特彆是對Mockito的流暢API設計給予瞭高度評價，並且展示瞭如何優雅地處理帶有副作用的依賴對象。最讓我眼前一亮的，是它提到瞭“可測試性設計”（Design for Testability），強調瞭優秀的架構本身就是最好的測試工具。讀完這部分，我不再是單純地“寫測試”瞭，而是開始思考“如何寫齣更容易測試的代碼”，這是一種從根本上提升代碼質量的思維轉變。這本書的論述風格非常**理性且富有洞察力**，充滿瞭經驗者的智慧沉澱。
评分說實話，剛拿到這本書時，我對它的期望值是中等的，畢竟市麵上關於這個主題的書汗牛充棟。然而，這本書在**構建和維護測試套件**方麵的實用性，徹底扭轉瞭我的看法。很多書寫瞭怎麼寫測試，但沒人深入講測試代碼的“工程化”問題。這本書則花瞭很大篇幅討論測試用例的命名規範、測試數據的隔離與重用，以及如何處理那些“頑固的”狀態依賴問題。尤其是在處理遺留係統（Legacy Code）的測試接入時，作者提供的“黃金圈”策略和“三步走”重構法，簡直是救命稻草。我之前在處理一個沒有經過任何測試的舊模塊時焦頭爛額，嘗試瞭各種方法都收效甚微，但書中的具體步驟和代碼示例，讓我有章可循。此外，它還涉及到瞭**持續集成（CI）環境中測試的配置與優化**，比如如何並行化測試以減少構建時間，以及如何利用測試報告生成有意義的度量指標。這本書的實用性在於，它預見到瞭你在實際項目中一定會遇到的那些“頭疼”的問題，並提前為你準備好瞭解決方案，讓你在麵對實際睏難時，可以快速定位到書中的對應章節，找到經過時間考驗的最佳實踐。它的結構設計非常貼閤項目開發的生命周期。
