我刚刚编写了我的第一个 GWTTestCase，但运行它总是给我一个 VerifyError。这是我的一个伟大测试套件的胚胎：
public void test() {
Invoice invoice = new Invoice();
invoice.setInvoiceDate(DateTimeFormat.getFormat(DomainResource.DATE_PATTERN).format(new Date()));
InvoiceEditorDriver driver = GWT.create(InvoiceEditorDriver.class);
InvoiceNumberEditor editor = new InvoiceNumberEditor();
driver.initialize(editor);
driver.edit(invoice);
assertFalse(driver.isDirty());
}
为了完整起见，我将 Google AppEngine 和 GWT 一起使用，我认为这可能与 AppEngine 的安全沙箱有关。
正在加载的类是“com.gargoylesoftware.htmlunit.SocksSocketFactory”。

我尝试排除给定课程的 GAE 验证，但没有成功。我不确定排除验证是否足够，以及是否可以为 jar 中的文件设置验证排除规则。
