【问题描述】:
我在执行 JUnit 测试期间尝试从我的类路径加载 sample.properties,但它在类路径中找不到该文件。如果我编写一个 Java Main 类,我就可以很好地加载文件。我正在使用下面的 ant 任务来执行我的 JUnit。
public class Testing {
@BeforeClass
public static void setUpBeforeClass() throws Exception {
Properties props = new Properties();
InputStream fileIn = props_.getClass().getResourceAsStream("/sample.properties");
**props.load(fileIn);**
}
}
JUnit:
<path id="compile.classpath">
<pathelement location="${build.classes.dir}"/>
</path>
<target name="test" depends="compile">
<junit haltonfailure="true">
<classpath refid="compile.classpath"/>
<formatter type="plain" usefile="false"/>
<test name="${test.suite}"/>
</junit>
</target>
<target name="compile">
<javac srcdir="${src.dir}"
includeantruntime="false"
destdir="${build.classes.dir}" debug="true" debuglevel="lines,vars,source">
<classpath refid="compile.classpath"/>
</javac>
<copy todir="${build.classes.dir}">
<fileset dir="${src.dir}/resources"
includes="**/*.sql,**/*.properties" />
</copy>
</target>
输出:
