网格在测试运行期间未遵循“平台”要求

我在2个不同节点上的硒网格中有2个测试。运行MAC的节点之一，另一个WIN。

当我在TestNG中指定时，运行两个测试（例如，我要启动“仅Win Chrome浏览器”测试和“仅MAC FF”测试。）

它会随机启动它们，有时mac会再次获得FF，如果win关闭，它将在mac上启动两个测试。

当我在测试中指定

<parameter name="platform" value="WINDOWS" />

它可以在Mac上启动此测试，反之亦然。

这是我的TestNG文件：

<suite name="TestSuite" parallel="tests">


    <test name="win chrome test">
        <parameters>
            <parameter name="platform" value="WINDOWS" />
            <parameter name="browser" value="chrome" />
            <parameter name="version" value="55.0" />
            <parameter name="url" value="https://google.com" />
        </parameters>
        <classes>
            <class name="com.ParallelTest.CreateRandomProfileTest"/>
            <class name="com.ParallelTest.LogInTest">

            </class>
        </classes>
    </test>


    <test name="mac firefox test">
        <parameters>
            <parameter name="platform" value="MAC" />
            <parameter name="browser" value="firefox" />

            <parameter name="url" value="https://google.com" />
        </parameters>

            <class name="com.ParallelTest.CreateRandomProfileTest"/>
