数据提供者使用RestAssured不匹配TestNG

问题描述

我一直在与RestAssured一起玩，并开始使用数据提供程序进行数据驱动的测试。我目前收到数据提供者不匹配错误。我假设这是因为即时通讯传递的字符串或我的api端点不正确吗？而且，这可能是完全不同的线程。如果在这种情况下我想对所有记录进行匹配，那么有没有更好的方法来检查所有1000条记录而不是少数几条？

public class test extends enablers {

@DataProvider
public Object[][] getData() {
    return new Object[][]{{24,"27.110.128.25","Fuling" },{145,"212.132.237.53","Muruni" }};
}



@Test(dataProvider = "getData")
public void GetUserId(String data,int userId,String ipAddress,String expectedCity) {

    given().
            pathParam("id",userId).pathParam("ip_address",ipAddress).
            when().
            get(id).
            then().
            assertthat().
            body(("id[0].'city'"),equalTo(expectedCity));

}
}

这是我的终点站

    String id = "http://bpdts-test-app-v2.herokuapp.com/user/{id}/{ip-address}";

解决方法

您的数据提供者应该像

@DataProvider(name="getData")
public Object[][] getData() {
    return new Object[][]{{24,"27.110.128.25","Fuling" },{145,"212.132.237.53","Muruni" }};
}

您的测试注释将基于@DataProvider name属性而不是方法名称来查找dataprovider

这样您的代码就会像

public class test extends enablers {
    
    @DataProvider(name="getData")
    public Object[][] getData() {
        return new Object[][]{{24,"Muruni" }};
    }
    
    
    
    @Test(dataProvider = "getData")
    public void GetUserId(String data,int userId,String ipAddress,String expectedCity) {    
        given().
                pathParam("id",userId).pathParam("ip_address",ipAddress).
                when().
                get(id).
                then().
                assertThat().
                body(("id[0].'city'"),equalTo(expectedCity));    
    }
}

您的dataprovider返回3个对象，而您的测试方法需要4个值，因为它有4个参数。请尝试通过更新dataprovider中所需的数据来返回4个长度的对象，例如

@DataProvider(name="getData")
    public Object[][] getData() {
        return new Object[][]{
                //Add required userid in place of 2
                //And 24,145 should be string
                {"24",2,{"145","Muruni" }
        };
     }

您的第一个值必须是字符串，以代替24和145
