我正在學習如何在GWT中執行單元測試。所以我創建了一個擴展GWTTestCase類的類,並在其中寫入測試方法。我是否需要爲每個使用GWTTestCase創建的單元測試方法添加前綴'test'?
問題是,如果除了繼承的'getModuleName'方法之外,如果我不在這個類(公共或私有)中甚至一個函數前面加上'test'這個詞,我會得到'初始化錯誤'。
現在我做錯了什麼或者是否添加此前綴是一個規則?如果其實際上是一個規則,這是什麼原因?在 '初始化錯誤' 的
public class hellotest extends GWTTestCase{
@Override
public String getModuleName() {
// TODO Auto-generated method stub
return "hellopackage.Hello1";
}
public void test()
{
assertTrue(true);
}
public void test2()
{
assertTrue(true);
}
public void notTest3() //Produces initialization error
{
assertTrue(true);
}
}

如果我想在擴展gwtTestCase的類中使用「非測試用例」方法,該怎麼辦?這可能嗎? –
當然可以。只是不要將它命名爲testXxx。 –
如果我在該類中創建任何沒有前綴「測試」的函數,如果它的私有或不是,我會得到初始化錯誤。 –
