测试(出现在project-tests.jar中):
package sample;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.testng.annotations.Test;
import utils.Base;
public class SampleTest {
@Test
public void Test() {
log.info("Sample Test called successfully.");
log.info("Invoking Base Method");
Base b = new Base();
b.testMethod();
}
}
Util(出现在project.jar中):
package utils;
import org.apache.commons.configuration.HierarchicalConfiguration;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import java.util.Map.Entry;
public class Base {
public void testMethod() {
log.info("Test method in utils.Base class called.");
}
}
假设已在两个类中创建并使用了日志。
在build.xml:
<project default="TestNGSimpleTest">
<path id="main_cp">
<pathelement location="dependency/testng-6.9.10.jar"/>
<pathelement location="dependency"/>
<pathelement location="."/>
</path>
<taskdef name="testng" classpathref="main_cp"
classname="org.testng.TestNGAntTask" />
<target name="test">
<testng classpathref="main_cp" >
<classfileset dir="." includes="sample/*.class"/>
</testng>
</target>
</project>
目标目录结构:
./dependency/{all-dependencies}.jar
./project.jar
./project-tests.jar
./build.xml
{all-dependencies}包括:
bsh-1.3.0.jar
bsh-2.0b4.jar
commons-beanutils-1.7.0.jar
commons-beanutils-core-1.8.0.jar
commons-collections-3.2.1.jar
commons-configuration-1.6.jar
commons-digester-1.8.jar
commons-lang-2.4.jar
commons-logging-1.1.1.jar
jcommander-1.48.jar
testng-6.9.10.jar
当我从IDE运行SampleTest时它运行正常,但是当我尝试使用ant(ant -v test)运行它时,我遇到以下错误:
[testng] The ' characters around the executable and arguments are
[testng] not part of the command.
[testng] Error: A JNI error has occurred, please check your installation and try again

我认为问题在于build.xml(因为我可以在IDE中运行它),但是无法弄清楚为什么会出现这个错误(java.lang.NoClassDefFoundError:com / beust / jcommander / ParameterException)以及如何修复它。我是否错误地指定了classfileset?我该怎么做呢?
通过其他线程表明testng jar可能已损坏,没有jcommander jar,无效的类路径 - 试过但没有帮助。
答案 0 :(得分:1)
要直接回答问题,似乎必须包含
<pathelement location="dependency/jcommander-1.48.jar"/>
main_cp
中的。
这个问题重复了较早的Suddenly can't run TestNG tests from ant ([testng] Caused by: java.lang.ClassNotFoundException: com.beust.jcommander.ParameterException),其答案似乎已经过时了。
实际上,似乎很久以来,jcommander既不包含在sonatype快照中,也不包含在github / graddle distrib中生成的jar。
因此,您必须在传递给testng
ant标记的路径中添加jcommander jar文件。
您的jcommander版本看起来很旧,并且声明testng任务的新recommended way是:
<taskdef resource="testngtasks" classpath="testng.jar" />
