我对 Java、TestNG 和 Selenium Webdriver（3 周）还比较陌生，而且我似乎没有按照 TestNG 的要求正确传递参数。
测试运行完美，但它说它失败了，原因如下：
org.testng.TestNGException:
The data provider is trying to pass 2 parameters but the method com.pragmaticqa.tests.AppTest2#twoUsersSignUp takes 1
这是我的代码：
public class AppTest2 {
public WebDriver driver;
public WebDriverWait wait;
@DataProvider(name = "dataProvider")
public Object[][] setUp() throws Exception {
File firefoxPath = new File(System.getProperty("lmportal.deploy.firefox.path", "C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe"));
FirefoxBinary ffox = new FirefoxBinary(firefoxPath);
ffox.setEnvironmentProperty("DISPLAY", ":20");
driver = new FirefoxDriver(ffox, null);
wait = new WebDriverWait(driver, timeoutInSeconds );
Object[][] data = new Object[1][2];
data[0][0] = driver;
data[0][1] = wait;
twoUsersSignUp(data);
return data;
}
@Parameters({ "data" })
@Test(dataProvider = "dataProvider")
public void twoUsersSignUp(@Optional Object[][] data) throws InterruptedException{
//test here
}
}
