在 Java 中运行 selenium webdriver 测试用例时出现参数错误

Question

我正在尝试在 Selenium webdriver 中运行此方法，但我继续收到此错误：

org.testng.TestNGException: 
Method PopulateBorrower requires 2 parameters but 0 were supplied in the @Test annotation.

--------->我做错了什么？代码如下。我在 SetUpBase 单独的类中设置了它。

@Test
public static void PopulateBorrower(String PrimaryBorrowerBaseName1,String PrimaryBorrowerBaseName)
{       
    String fName= PrimaryBorrowerInputDictionary.get(BorrowerFirstNameElement);
    String lName=PrimaryBorrowerInputDictionary.get(BorrowerLastNameElement);
    String suffix=PrimaryBorrowerInputDictionary.get(BorrowerSuffixElement);
    String social=PrimaryBorrowerInputDictionary.get(BorrowerSocialSecurityNumberElement);
    String homePhone=PrimaryBorrowerInputDictionary.get(BorrowerHomePhoneNumberElement);
    String schoolYears=PrimaryBorrowerInputDictionary.get(BorrowerYearsInSchoolElement);

    driver.findElement(By.id(PrimaryBorrowerBaseName1 + BorrowerFirstNameElement)).sendKeys(fName);
    driver.findElement(By.id(PrimaryBorrowerBaseName1 + BorrowerLastNameElement)).sendKeys(lName);
    driver.findElement(By.id(PrimaryBorrowerBaseName1 + BorrowerSuffixElement)).sendKeys(suffix);
    driver.findElement(By.name(PrimaryBorrowerBaseName + BorrowerHomePhoneNumberElement)).sendKeys(social);

    driver.findElement(By.name(PrimaryBorrowerBaseName + BorrowerHomePhoneNumberElement)).sendKeys(homePhone);
    driver.findElement(By.name(PrimaryBorrowerBaseName + BorrowerYearsInSchoolElement)).sendKeys(schoolYears);
    driver.findElement(By.name(PrimaryBorrowerBaseName +BorrowerMarriageStatusElement )).click();


    assertEquals(driver.findElement(By.id(PrimaryBorrowerBaseName + BorrowerFirstNameElement))
                .getText(), fName);

    assertEquals(driver.findElement(By.id(PrimaryBorrowerBaseName + BorrowerLastNameElement))
            .getText(), lName);

    assertEquals(driver.findElement(By.id(PrimaryBorrowerBaseName + BorrowerSuffixElement))
            .getText(), suffix);

    assertEquals(driver.findElement(By.id(PrimaryBorrowerBaseName + BorrowerHomePhoneNumberElement))
            .getText(), homePhone);

    assertEquals(driver.findElement(By.id(PrimaryBorrowerBaseName + BorrowerYearsInSchoolElement))
            .getText(), schoolYears);

    assertTrue(driver.findElement(By.id(PrimaryBorrowerBaseName + BorrowerMarriageStatusElement))
            .isSelected());
 }

Answer 1

您的单元测试是否使用@DataProvider 注释（JUnit 4.11 中的@Parameterized）？如果是这样，并且您已经定义了数据提供者方法，那么您的 @Test 注释需要像这样识别它：

@Test
@Parameters(value="number", value2="digit")
public void parameterIntTest(int number, int digit) {
    System.out.println("Parameterized Number is : " + number + " and " + digit);
}

Answer 2

为什么使用静态函数作为测试？它不应该是静态的！

Answer 3

TestNGException 即将到来，因为您的 @Test 方法需要 2 个参数（即 PrimaryBorrowerBaseName1 和 PrimaryBorrowerBaseName），但您没有传递它们。

要解决此问题，您需要在TestNG 调用您的@Test 方法（即PopulateBorrower）时提供这些参数。 TestNG 提供了 2 种方法来做同样的事情。

在TestNG 中提供parameters

1. Parameters from testng.xml
2. Parameters with DataProviders

您可以尝试以下任何一种方法来解决您的问题。

解决方案 1：testng.xml 中的参数

testng.xml 文件：

<suite name="My Suite">
    <parameter name="primary-borrower-base-name1" value="value1" />
    <parameter name="primary-borrower-base-name"  value="value"/>
    <test name="My Test">
        <classes>
            <class
                name="yourpackage.PopulateBorrowerTestClass2" />
        </classes>
    </test>
</suite>

你的测试类：

package yourpackage;

import org.testng.annotations.Parameters;
import org.testng.annotations.Test;

public class PopulateBorrowerTestClass2 {

    @Parameters({ "primary-borrower-base-name1", "primary-borrower-base-name" })
    @Test
    public static void PopulateBorrower(String PrimaryBorrowerBaseName1, String PrimaryBorrowerBaseName)
    {       
        System.out.println(PrimaryBorrowerBaseName1 + " " + PrimaryBorrowerBaseName);
       //your all code goes here
     }
}

解决方案 2：使用 DataProviders 的参数

testng.xml 文件：

<suite name="My Suite">
    <test name="My Test">
        <classes>
            <class name="yourpackage.PopulateBorrowerTestClass1" />
        </classes>
    </test>
</suite>

你的测试类：

package yourpackage;

import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

public class PopulateBorrowerTestClass1 {

    //This method will provide data to any test method that declares that its Data Provider
    //is named "test1"
    @DataProvider(name = "test1")
    public Object[][] createData1() {
     return new Object[][] {
       { "PrimaryBorrowerBaseName1Value", "PrimaryBorrowerBaseNameValue" }
     };
    }

    //This test method declares that its data should be supplied by the Data Provider
    //named "test1"
    @Test(dataProvider = "test1")
    public static void PopulateBorrower(String PrimaryBorrowerBaseName1, String PrimaryBorrowerBaseName)
    {       
        System.out.println(PrimaryBorrowerBaseName1 + " " + PrimaryBorrowerBaseName);
       //your all code goes here
     }
}
