使用Maven集成JMeter執行接口測試的詳細步驟2-優化html報告展示
1.背景
在我的上一篇博客《使用Maven集成JMeter執行接口測試的詳細步驟，以及多種異常的處理方式》中已經詳細介紹瞭如何通過Maven執行JMeter的腳本，但文末最後生成的測試結果html文件還是十分的“質樸”，它只記錄了JMeter取樣器的執行結果，而執行過程中，發出、收到的報文（包括Headers和Body）都沒有展示出來。這對於接口的功能測試十分不方便，因爲無法檢查請求的詳情，不便於定位錯誤原因等，如下圖：
2.問題原因
其實根本原因是出在JMeter的jtl報告文件上。
在上一篇博文中，我們知道，所有生成的HTML報告，都是以target\jmeter\results下的jtl文件爲數據源的，這個jtl是JMeter生成的標準的測試結果文件，如下圖：
打開此文件，發現確實只是記錄了請求的結果，並沒有記錄詳情，如下圖：
3.優化方式
3.1 修改JMeter的.properties配置文件
爲了讓jtl文件保存請求詳情，我們可以去修改src\test\jmeter\路徑下，JMeter的.properties配置文件。個人建議只修改user.properties，不用去動jmeter.properties文件，如下圖：
添加如下設置：
jmeter.save.saveservice.data_type=true
jmeter.save.saveservice.label=true
jmeter.save.saveservice.response_code=true
jmeter.save.saveservice.response_data=true
jmeter.save.saveservice.response_data.on_error=false
jmeter.save.saveservice.response_message=true
jmeter.save.saveservice.successful=true
jmeter.save.saveservice.thread_name=true
jmeter.save.saveservice.time=true
jmeter.save.saveservice.subresults=true
jmeter.save.saveservice.assertions=true
jmeter.save.saveservice.latency=true
jmeter.save.saveservice.connect_time=true
jmeter.save.saveservice.samplerData=true
jmeter.save.saveservice.responseHeaders=true
jmeter.save.saveservice.requestHeaders=true
jmeter.save.saveservice.encoding=false
jmeter.save.saveservice.bytes=true
jmeter.save.saveservice.sent_bytes=true
jmeter.save.saveservice.url=true
jmeter.save.saveservice.filename=true
jmeter.save.saveservice.hostname=true
jmeter.save.saveservice.thread_counts=true
jmeter.save.saveservice.sample_count=true
jmeter.save.saveservice.idle_time=true
然後保存。
使用clean verify的Maven命令重新運行JMeter，重新查看結果。這時可以看見jtl文件已經保存了請求的詳情，如下圖：
這樣就成功了第一步。
3.2 使用新的xsl報告模板文件
接下來，要使用新的xsl報告模板文件，因爲在上一篇博客中也提過，Maven需要解析指定的xsl模板文件來生成html結果報告。下方爲自定義的xsl報告模板：
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="html" indent="no" encoding="UTF-8" doctype-public="-//W3C//DTD HTML 4.01 Transitional//EN" doctype-system="http://www.w3.org/TR/html4/loose.dtd"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/testResults">

把上述內容，保存成xsl文件，放到src\test\resources的路徑下，然後修改相應的pom.xml配置即可，如下圖：
3.3 查看效果
重新執行clean verify的Maven命令，在target\jmeter\html_detail_report路徑下查看運行出來的html報告，如下圖：
成功！怎麼樣，看起來是不是爽多了~~
4.補充說明
注意，在壓力測試中，不要開啓記錄請求詳情。
其實JMeter默認是故意不記錄這些請求的，因爲JMeter 在真正的壓測工程中，如果邊壓測，邊將請求和響應數據寫入 jtl 和xml文件，會無形之中加重 JMeter 的負擔，影響壓力源的性能，進而影響測試結果。
