在finish方法中完成批处理请求后，我正在调用另一个批处理类。有人能告诉我为什么我在testmethod中调用一个批处理类时出现此错误吗？请提供一些帮助

当您可以从另一个批处理类调用批处理类时，您可以从测试类中只调用一个批处理类。因此你正面临着这个错误

另一种方法是检查调用批处理类的finish方法，无论您是在测试上下文中还是在常规上下文中。您可以使用test.isRunningTest（）执行此操作

System.UnexpectedException: No more than one executeBatch can be called from within a testmethod. Please make sure the iterable returned from your start method matches the batch size, resulting in one executeBatch invocation.
