Spring boot custom properties for junit test

Question

Here is the class that gets its pathToFile from application.properties.

@Component
public class CSVReader {
 @Value("${name.basics}")
 private String pathToFile;
 (other code)
}

The problem is: how can I substitute application.properties for testing?

• Januson: Does this answer your question? How do I mock an autowired @Value field in Spring with Mockito?

Answer 1

You can use spring boot test annotation:

@RunWith(SpringRunner.class)
@SpringBootTest(properties = {"name.basics=whatever"})
public class YourTestClass {
@Autowired 
CSVReader cvsReader;
@Test
public void yourTest() {
//...

Second option is to put application-test.properties containing replacements in src/test/resources folder of your project
