How to read file from test resources in java unit test

#java #testing #codever #snippets

Use the getClass().getClassLoader().getResourceAsStream() to get an InputStream for the wanted resource. In the following snippet we access the bookmark-example.xml file resource, which is placed directly in the src/test/resources folder:

@Test void shouldUnmarshallXmlToJava() throws JAXBException { JAXBContext jaxbContext = JAXBContext.newInstance("dev.codepal.bookmark"); final var jaxbUnmarshaller = jaxbContext.createUnmarshaller(); InputStream inStream = getClass().getClassLoader().getResourceAsStream( "bookmark-example.xml"); JAXBElement<Bookmark> o = (JAXBElement<Bookmark>)jaxbUnmarshaller.unmarshal(inStream); Bookmark bookmark = o.getValue(); assertThat(bookmark.getTitle(), equalTo("CodepediaOrg")); }
