簡單的jMeter non gui測試以NonGUIDriver java.lang.NullPointerException中的錯誤結束

Question

我正在嘗試在非gui中運行簡單的jMeter測試，我正在使用一個簡單的命令，例如：

jmeter -n -t davelatal-cz.jmx -Jusers=4 -Jduration=300

如下面的屏幕截圖所示，我更改了線程首選項： 線程首選項

因此，如果我嘗試運行此簡單的HTTP Request測試，bash會顯示以下錯誤：

Error in NonGUIDriver java.lang.NullPointerException

屏幕截圖：

我已經嘗試過更改項目文件夾，使用google進行搜索，但是在選項末尾。 有人可以告訴我我做錯了嗎？ 還是問題出在哪里？

謝謝

Answer 1

您很可能正在運行使用JMeter 2.11上較新的JMeter版本創建的測試，因此我的期望是您需要升級JMeter。

JMeter當前版本是JMeter 3.2 。

您始終可以從“ JMeter下載”頁面獲取最新的JMeter版本。

因此，我建議從似乎從Linux發行版存儲庫中獲得的JMeter切換到可以直接從Apache下載的二進制包。 只需拉壓縮包，將其解壓縮到某個位置，然后從該文件夾運行JMeter。 請確保您正在運行的JMeter作為./jmeter或將其添加到您的系統路徑的一個是從倉庫前。
