如何将文本文件资源读入 Java 单元测试? [英] How to read a text-file resource into Java unit test?

问题描述

我有一个单元测试需要处理位于 src/test/resources/abc.xml 中的 XML 文件.将文件内容放入 String 的最简单方法是什么?

I have a unit test that needs to work with XML file located in src/test/resources/abc.xml. What is the easiest way just to get the content of the file into String?

推荐答案

最后我找到了一个巧妙的解决方案，感谢 Apache Commons:

Finally I found a neat solution, thanks to Apache Commons:

package com.example;
import org.apache.commons.io.IOUtils;
public class FooTest {
  @Test 
  public void shouldWork() throws Exception {
    String xml = IOUtils.toString(
      this.getClass().getResourceAsStream("abc.xml"),
      "UTF-8"
    );
  }
}

完美运行.文件 src/test/resources/com/example/abc.xml 已加载(我正在使用 Maven).

Works perfectly. File src/test/resources/com/example/abc.xml is loaded (I'm using Maven).

如果你用 "/foo/test.xml" 替换 "abc.xml"，这个资源将被加载:src/test/resources/foo/test.xml

If you replace "abc.xml" with, say, "/foo/test.xml", this resource will be loaded: src/test/resources/foo/test.xml

您也可以使用 Cactoos:

package com.example;
import org.cactoos.io.ResourceOf;
import org.cactoos.io.TextOf;
public class FooTest {
  @Test 
  public void shouldWork() throws Exception {
    String xml = new TextOf(
      new ResourceOf("/com/example/abc.xml") // absolute path always!
    ).asString();
  }
}
