我有这两个：
public String[] firstname = new String[2];
public String[] lastname = new String[2];
我希望将它们传递给这个方法（已经从其他地方接受了一些数据）：
@Parameters({ "driver", "wait", "firstname[]", "lastname[]" })
@Test(dataProvider = "dataProvider")
public void oneUserTwoUser(WebDriver driver, WebDriverWait wait, String[] firstname, String[] lastname) {
//code
}
这是来自另一个类的数据提供者：
public class AppData extends CSVReader { //was public abstrac class before
public static WebDriver driver;
public WebDriverWait wait;
public String[] firstname = new String[2];
public String[] lastname = new String[2];
public String firstname1;
public String firstname2;
public String lastname1;
public String lastname2;
@DataProvider(name = "dataProvider")
public Object[][] setUp(ArrayList<ArrayList<String>> array) throws Exception {
driver = new EventFiringWebDriver(new FirefoxDriver(ffox, profile, dc))
.register(eventListener);
wait = new WebDriverWait(driver, timeoutInSeconds);
int randomUser1 = randomizer (1, 250);
int randomUser2 = randomizer (1, 250);
firstname1 = array.get(randomUser1).get(0);
firstname2 = array.get(randomUser2).get(0);
lastname1 = array.get(randomUser1).get(1);
lastname2 = array.get(randomUser2).get(1);
firstname[0] = firstname1.replace(" ", "");
firstname[1] = firstname2.replace(" ", "");
lastname[0] = lastname1.replace(" ", "");
lastname[1] = lastname2.replace(" ", "");
Object[][] setUp = new Object[1][4];
setUp[0][0] = driver;
setUp[0][1] = wait;
setUp[0][2] = firstname;
setUp[0][3] = lastname;
return setUp;
}
你能告诉我这里我做错了什么吗？我是Java新手 - 4周。
我收到此错误：
SKIPPED: oneUserTwoUser
java.lang.IllegalArgumentException: wrong number of arguments

编辑这是重构的代码
@Parameters({ "driver", "wait", "array" })
@Test(dataProvider = "dataProvider")
public void oneUserTwoUser(WebDriver driver, WebDriverWait wait, ArrayList<ArrayList<String>> array) throws Exception {
String[] firstname = new String[2];
String[] lastname = new String[2];
String firstname1;
String firstname2;
String lastname1;
String lastname2;
//parametrize tests by reading the array passed from CSV reader class
int randomUser1 = randomizer(1, 250);
int randomUser2 = randomizer(1, 250);
firstname1 = array.get(randomUser1).get(0);
firstname2 = array.get(randomUser2).get(0);
lastname1 = array.get(randomUser1).get(1);
lastname2 = array.get(randomUser2).get(1);
firstname[0] = firstname1.replace(" ", "");
firstname[1] = firstname2.replace(" ", "");
lastname[0] = lastname1.replace(" ", "");
lastname[1] = lastname2.replace(" ", "");
System.out.println(firstname[0]);
System.out.println(lastname[0]);
System.out.println(firstname[1]);
System.out.println(lastname[1]);

答案 0 :(得分：1)
@DataProvider来自TestNG，是的，它需要是一个2D数组（所以测试可以从不同的数据集中运行多次）
你做错了是你的@Parameters(...)行。参数注释和DataProvider注释用于相同的目的，但它们以不同的方式执行。
但是，我也对你的setUp函数感到困惑......因为DataProvider函数不应该接受参数（Method除外）。考虑一种不同的方式，即ArrayList<ArrayList<String>>，例如this post中解释的方式。
最后，你发表评论说该课程是公开抽象的......你和@DataProvider在同一个班级考试吗？如果没有，带@Test的班级必须使用@DataProvider扩展班级。 （我建议将其抽象化，但这取决于你）

我不知道Selenium API，但根据你的堆栈跟踪，你可能想尝试这个，如果你自动注入参数并且它会抛出那个错误。
Objec[] data = new Object[4];
data[0] = driver;
data[1] = wait;
data[2] = firstname;
data[3] = lastname;
它是一个多维数组没有逻辑意义，因为数组本身是Java中的对象，并且用于传递参数的注入方法可能会考虑到Object数组。因此，firstname和lastname数组可以像处理该一维数组中的任何Object后代一样轻松处理。
