How to read a text-file resource into Java unit test?

by

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"
    );
  }
}

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

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

You can also use 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();
  }
}
