运行testng.xml时获取java.lang.NullPointerException错误

运行testng.xml时出现以下错误

有谁能帮我…为什么我会犯这个错误。您的帮助将不胜感激

在我看来，它似乎找不到您的

testng.xml

文件。这是XML解析器抛出NPE的一个可能原因：一个

null

输入。我看到

ant

默认为

build.xml

。您是否也有

build.xml

文件

<target name="run_testNG" description="Run TestNG">
    <testng classpathref="compile.classpath" haltOnfailure="false">
        <xmlfileset dir="/softwares/cruisecontrol-bin-2.8.3/run_test/" includes="testng.xml" />

查看

run\u testNG

脚本，您可能需要为文件添加完整路径。

问题似乎在于该文件不是testNG XML文件。这是一个Ant构建文件

<target name="run_testNG" description="Run TestNG">
    <testng classpathref="compile.classpath" haltOnfailure="false">
        <xmlfileset dir="/softwares/cruisecontrol-bin-2.8.3/run_test/" includes="testng.xml" />
    </testng>
</target>
<target name="start-server">
    <java jar="/softwares/selenium/selenium-server-standalone-2.0b2.jar" fork="true" spawn="true">
        <arg line="-timeout 30"/>
        <jvmarg value="-Dhttp.proxyHost=proxy.corporate.com"/>
        <jvmarg value="-Dhttp.proxyPort=3128"/>
    </java>
</target>
<target name="stop-server">
    <get taskname="selenium-shutdown"
        src="http://localhost:4444/selenium-server/driver/?cmd=shutDownSeleniumServer"
        dest="result.txt" ignoreerrors="true" />
    <echo taskname="selenium-shutdown" message="DGF Errors during shutdown are expected" />
</target>
<taskdef resource="testngtasks" classpath="/softwares/selenium/selenium-2.0b2/libs/testng-5.14.1.jar" />

有关真实testng XML文件的外观信息，请参阅。或者，重命名文件并使用Ant运行测试；e、 g

<target name="run_testNG" description="Run TestNG">
    <testng classpathref="compile.classpath" haltOnfailure="false">
        <xmlfileset dir="/softwares/cruisecontrol-bin-2.8.3/run_test/" includes="testng.xml" />
    </testng>
</target>
<target name="start-server">
    <java jar="/softwares/selenium/selenium-server-standalone-2.0b2.jar" fork="true" spawn="true">
        <arg line="-timeout 30"/>
        <jvmarg value="-Dhttp.proxyHost=proxy.corporate.com"/>
        <jvmarg value="-Dhttp.proxyPort=3128"/>
    </java>
</target>
<target name="stop-server">
    <get taskname="selenium-shutdown"
        src="http://localhost:4444/selenium-server/driver/?cmd=shutDownSeleniumServer"
        dest="result.txt" ignoreerrors="true" />
    <echo taskname="selenium-shutdown" message="DGF Errors during shutdown are expected" />
</target>
<taskdef resource="testngtasks" classpath="/softwares/selenium/selenium-2.0b2/libs/testng-5.14.1.jar" />

$ mv testng.xml build.xml
$ ant test

然而，奇怪的是，当您为testng提供一个XML文件时，它竟然以如此惊人的方式失败了。可能测试不足？：-）

我也有同样的问题，

<target name="run_testNG" description="Run TestNG">
    <testng classpathref="compile.classpath" haltOnfailure="false">
        <xmlfileset dir="/softwares/cruisecontrol-bin-2.8.3/run_test/" includes="testng.xml" />
    </testng>
</target>
<target name="start-server">
    <java jar="/softwares/selenium/selenium-server-standalone-2.0b2.jar" fork="true" spawn="true">
        <arg line="-timeout 30"/>
        <jvmarg value="-Dhttp.proxyHost=proxy.corporate.com"/>
        <jvmarg value="-Dhttp.proxyPort=3128"/>
    </java>
</target>
<target name="stop-server">
    <get taskname="selenium-shutdown"
        src="http://localhost:4444/selenium-server/driver/?cmd=shutDownSeleniumServer"
        dest="result.txt" ignoreerrors="true" />
    <echo taskname="selenium-shutdown" message="DGF Errors during shutdown are expected" />
</target>
<taskdef resource="testngtasks" classpath="/softwares/selenium/selenium-2.0b2/libs/testng-5.14.1.jar" />

但是我发现我正在提取一个dbUnit数据集文件，该文件与我设置的提取testngxml文件（*test.xml）的模式相匹配。 只需重命名文件，我就可以开始了

<target name="run_testNG" description="Run TestNG">
    <testng classpathref="compile.classpath" haltOnfailure="false">
        <xmlfileset dir="/softwares/cruisecontrol-bin-2.8.3/run_test/" includes="testng.xml" />
    </testng>
</target>
<target name="start-server">
    <java jar="/softwares/selenium/selenium-server-standalone-2.0b2.jar" fork="true" spawn="true">
        <arg line="-timeout 30"/>
        <jvmarg value="-Dhttp.proxyHost=proxy.corporate.com"/>
        <jvmarg value="-Dhttp.proxyPort=3128"/>
    </java>
</target>
<target name="stop-server">
    <get taskname="selenium-shutdown"
        src="http://localhost:4444/selenium-server/driver/?cmd=shutDownSeleniumServer"
        dest="result.txt" ignoreerrors="true" />
    <echo taskname="selenium-shutdown" message="DGF Errors during shutdown are expected" />
</target>
<taskdef resource="testngtasks" classpath="/softwares/selenium/selenium-2.0b2/libs/testng-5.14.1.jar" />

希望这能有所帮助，尽管这个问题不久前就被提出了。

Parser.java和TestNG.java中的调用是什么样子的？NullPointerException不是来自XML，而是来自JAVA codeCorrect，看起来testng.XML文件实际上是build.XML。

    </testng>

<target name="start-server">
