我们有一个非常大的自动化套件，需要花费大量的时间来运行。这些是Windows应用程序的UI测试，我们使用LeanFT＆amp; NUnit的。它不是网络我们还没有任何类型的并行/网格解决方案启动和运行。
整个套件有大约110个测试，所有测试都在一个代理上运行。大约80％的方式，测试运行随机断开＆amp;我们看到了这个错误
@Override
public void onBindViewHolder(SingleViewHolder holder, int position) {
final Single single = singleList.get(position);
if (single.getImg() != 0 ) {
String resourceName = String.valueOf(single.getImg());
int checkExistence = mContext.getResources().getIdentifier(resourceName , "drawable", mContext.getPackageName());
// Most secure checking for resource availability
if (checkExistence != 0 ) {
try {
holder.img.setImageResource(single.getImg());
} catch (Exception e) {
e.printStackTrace();
}
}
}
holder.title.setText(single.getTitle());
}
在测试套件中间出现运行时错误的原因是什么？在使用这个框架扩展测试自动化时，有没有其他人经历过类似的事情？谢谢！
这是另一个堆栈跟踪，来自最初的断开连接。这可以在hpe.leanft.runtime日志文件
中找到Error Details
