我想用GwtTestCase來測試我的gwt項目。
但我不能創建一個Composite組件的實例。如何使用GwtTestCase使用ui binder測試gwt複合組件？
下面是代碼和堆棧跟蹤...
Login.java（我的複合部件）
public class Login extends Composite{
@UiField
TextBox userName;
@UiField
TextBox password;
@UiField
Button loginButton;
private static LoginUiBinder uiBinder = GWT.create(LoginUiBinder.class);
interface LoginUiBinder extends UiBinder<Widget, Login> {}
public Login() {
initWidget(uiBinder.createAndBindUi(this));
loginButton.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
Window.alert("clicked");
}
});
}
}
Login.ui.xml（UI粘合劑XML內容）
<g:HTMLPanel>
<div>
<g:Label text="username:"></g:Label>
<g:TextBox ui:field="userName"></g:TextBox>
</div>
<div>
<g:Label text="password:"></g:Label>
<g:TextBox ui:field="password"></g:TextBox>
</div>
<g:Button ui:field="loginButton" text="Login"></g:Button>
</g:HTMLPanel>
LoginTest.java（這是我的Gwt TesC ASE）
public class SampleGwtTestCase extends GWTTestCase{
public void test01(){
Login login = new Login();
}
@Override
public String getModuleName() {
return "com.mycompany.TestingGwt";
}
}
錯誤堆棧跟蹤

我做測試嗎？
配置中還需要什麼？ 測試用例可以成功地爲沒有ui活頁夾的類工作。
GWT.create(...)和原生JavaScript代碼也正常工作。
我在'gwt模塊中用'
