下面是执行驱动脚本时显示的问题

第151行keyword_execution_result=(String)method[i].invoke(keywords,object,data);

第 107 行 executeKeywords();//多组数据

第 63 行 test.start()

第51行driver.manage().timeouts().implicitlyWait(implicitWaitTime, TimeUnit.SECONDS);

Answer 1

当您清除它的值是否被分配时，对implicitWaitTime略有怀疑，但从那以后(20)似乎没问题。您可能应该确保为您的情况中的驱动程序分配一个值并在执行阶段成功创建。
