Question

我只是在学习依赖注入，而我根本就没有得到它的逻辑。更不用说，TestNG的要求对我来说总是太奇怪了。

我有这个提供数据的类，以及需要它的测试类：

public abstract class AppData { // extends Mailer

    @DataProvider(name = "dataProvider")
    public static Object[][] setUp() throws Exception {


        //prepare the data here - code.

        //pass the data to the test case
        Object[][] setUp = new Object[1][4];
        setUp[0][0] = driver;
        setUp[0][1] = wait;
        setUp[0][2] = array;
        setUp[0][3] = array2;   
        return setUp;
    }
}

这是测试类

public class AppTest { 

//this is my attempt to make a dependency injection, completely blindly shooting in the dark
    private AppData appdata;

    public AppTest (
            AppData appdata
        ) {
           this.appdata = appdata;
        }



@Factory(dataProviderClass=com.fmydomain.tests.AppData.class,dataProvider="dataProvider")
    public void oneUserTwoUser(WebDriver driver, WebDriverWait wait, ArrayList<ArrayList<String>> array, ArrayList<ArrayList<String>> array2) throws Exception {

    }
}

我运行时遇到此错误：

org.testng.TestNGException: 
The factory method class com.f1rstt.tests.AppTest3.oneUserTwoUser() threw an exception
    at org.testng.internal.FactoryMethod.invoke(FactoryMethod.java:93)
    at org.testng.internal.TestNGClassFinder.<init>(TestNGClassFinder.java:140)

编辑：我也尝试过以下方式：

public class AppTest3 { 

    private AppData appdata = new AppData();

    public AppTest3(AppData appdata) {
        this.appdata = appdata;
    }

    WebDriver driver = AppData.driver;
    WebDriverWait wait = AppData.wait;
    ArrayList<ArrayList<String>> array = AppData.array;
    //ArrayList<ArrayList<String>> array2 = AppData.array2;

    @Parameters({ "driver", "wait", "array" })
    @Test
    public void oneUserTwoUser(WebDriver driver, WebDriverWait wait, ArrayList<ArrayList<String>> array) throws Exception {

但是我收到了这个错误：

org.testng.TestNGException: 
Parameter 'driver' is required by @Test on method oneUserTwoUser but has not been marked @Optional or defined

在重构和安装DI框架Spring Framework and TestNG: unable to pass some parameters

之后，此处提供了答案

TestNG @Factory注释+关于依赖注入的知识不够
