testng同时使用@Parameter和DataProvider

Question

selenium跑case的时候使用testng驱动，想在testng.xml中配置多个test，对应不同的浏览器，然后在具体的test中使用DataProvider来获取测试数据，但是在运行过程中报参数没有在testng.xml中定义，这个搞不定了。难道是testng不支持这样使用么。报错信息如下：

Parameter 'browserType' is required by @Configuration on method before
but has not been defined in C:cygwin64homevictorworkspaceselenium-spoon-samplersrctestresourcestestng.xml

    public void before(String browser)

        System.out.println(browser);

    @Test(dataProvider = "KeywordDataProvider", dataProviderClass = KeywordData.class)
    public void test(String keyword)
    {
        System.out.println(keyword);

}

下面是dataprovider：

package com.yeetrack.selenium.data;

import org.testng.annotations.DataProvider;

/**
 * Created by xuemeng.wang on 2014/7/29.
 */
public class KeywordData
{
    @DataProvider(name="KeywordDataProvider")
    public static Object[][] keywordProvider()
    {
        return new Object[][] {{"apache"}, {"tomcat"}};
    }
}

Answer 1

@Parameters({"browserType"}) 这个和@Parameters("browserType")是等价的。

Answer 2

@Parameters({"browserType"})

Answer 3

呃，仔细检查了，原来我pom.xml 中testng引错了。一切正常。thx

Answer 4

刚刚试了一下，毫无压力
