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

Question

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?

Answer 1

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();   } } 

Answer 2

Right to the point :

ClassLoader classLoader = getClass().getClassLoader(); File file = new File(classLoader.getResource("file/test.xml").getFile());
