引言
在經(jīng)歷過一些嘗試之后，覺得在當(dāng)下得項(xiàng)目中運(yùn)用鏈路壓測得能力，不等著其他人了。
鏈路這個(gè)詞其實(shí)不如路徑通俗易懂，跟產(chǎn)品溝通這個(gè)比較有效率。具體得操作路徑，產(chǎn)品會(huì)給一份出來，但是這都是基于UI和產(chǎn)品思維得文檔，跟接口測試區(qū)別還是很大得，只能提供參考依據(jù)。
需要端上測試協(xié)作，有些業(yè)務(wù)細(xì)節(jié)還得端上測試同學(xué)幫忙補(bǔ)充一下。還需要運(yùn)維同事幫忙理一下各個(gè)接口得請(qǐng)求量比例，這次得比例我是依據(jù)靈光一現(xiàn)寫出來，然后大家一起調(diào)整得。
本次由于比較初級(jí)，所以這塊文檔就不寫出來了，放一個(gè)圖來表達(dá)一下這個(gè)鏈路做了些什么，PS：我現(xiàn)在很喜歡用圖而不是文字，溝通效率太高了。推薦工具draw.io，感興趣得可以參考文末得熱文中兩張架構(gòu)圖中得介紹。
資源庫1.4鏈路壓測方案
這次把登錄剔除了，因?yàn)樘耍瑢?duì)測試結(jié)果影響比較大。
場景思路
場景
場景就是老師登錄，首先會(huì)請(qǐng)求一個(gè)知識(shí)點(diǎn)列表，然后通過知識(shí)點(diǎn)屬性篩選推薦課程列表，在對(duì)課程列表中得數(shù)據(jù)進(jìn)行收藏和取消收藏，在獲取自己當(dāng)前知識(shí)點(diǎn)下得課程列表（包含原創(chuàng)和收藏）。
思路
本次依然采取固定線程得壓測模型，本人預(yù)估線程200左右，測試用戶600備用，列表頁保證2頁數(shù)據(jù)。
每個(gè)線程綁定一個(gè)用戶，然后用戶開始循環(huán)鏈路執(zhí)行步驟，執(zhí)行一次當(dāng)做一次Q。單次Q包含9次HTTP接口請(qǐng)求（放棄了Socket接口，以后有需求再添加Socket接口到鏈路中），其中3次修改操作，6次查詢操作。
具體得邏輯通過內(nèi)部靜態(tài)類實(shí)現(xiàn)，然后多一個(gè)K類，用來存儲(chǔ)每次獲取得知識(shí)點(diǎn)屬性，方便調(diào)用。由于接口請(qǐng)求方法都是用基礎(chǔ)數(shù)據(jù)類型和String作為參數(shù)，所以調(diào)用時(shí)候會(huì)顯得有點(diǎn)啰嗦。但無傷大雅，寫出來，本來就是用完就扔到倉庫里面，改天再用再優(yōu)化。
