Question

我想知道如何使用不同的数据集多次运行testng xml。我基于testng xml中存在的testcaseno参数从excel文件中获取数据，并且它正在按预期工作。现在我想通过对多组数据使用相同的xml文件来扩展我的测试。

testng.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="Sample Test Suite 1">
   <parameter name="browser" value="Firefox"/>
   <parameter name="TestCaseNo" value="1"/>
     <test name="Testcase1">

      <classes>
            <class name="packagename.ABCTest">
            <methods> 
            <include name="method_A" />
            <include name="method_B" />
            <include name="method_C"/>
            <include name="method_D"/>
            </methods>
            </class>
      </classes>
        </test> 
</suite>

截至目前，我的excel实用程序从testng xml获取testcaseno值并获取与所需行对应的数据。我想为5个测试用例运行相同的testng xml。

请帮助我实现这一目标。我可以实现基于测试用例号的调用计数，因为我依赖于来自testng xml的参数来从excel获取值。

提前致谢！

以下是您的问题的解决方法，使用@DataProvider和@Factory注释在运行时创建测试。根据您的需要，根据事情修改...

根据您的要求更改getExcelData（）方法
根据要求

这将使用一个参数执行整个测试套件一次，然后使用第二个参数执行。

Class SomeTest

import org.testng.annotations.Test;

public class SomeTest {

    private String username;
    private String password;

    public SomeTest(String username, String password) {
        this.username = username;
        this.password = password;
    }

    @Test
    public void firstTest() {
        System.out.println("Test #1 with data: "+username+" and "+password);
    }

    @Test
    public void secondTest() {
        System.out.println("Test #2 with data: "+username+" and "+password);
    }

    @Test
    public void thirdTest() {
        System.out.println("Test #3 with data: "+username+" and "+password);
    }
}
