java无法在testng中实例化类问题
我在运行TestNG XML时遇到一个问题，它给了我一个错误“无法实例化类测试。ZonesTestCases”，请检查下面的XML和“ZonesTestCases”以及打开浏览器和URL路径的测试库
testngxml
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Idialogue Project">
<test name="Login and Zone Test Cases">
<parameter name="browserType" value="chrome" />
<parameter name="appURL"
value="https://41.206.136.84/IDialogueTest/login" />
<classes>
<class name="Tests.ZonesTestCases" />
</classes>
</test>
</suite>

大多数情况下，这是基于IDE配置的。请检查特定于浏览器的项目配置设置。错误的原因基本上是TESNNG xml文件无法找到测试。分区用例类
