Spring TestRestTemplate doesn't work automatically
I am currently using Spring Boot 1.5.4 along with Junit 5 and Java 8.
I want to set up integration tests for multiple records that are stored in a csv file using Junit ParameterizedTest.
Here is the code:
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
class MatchingIT {
@Autowired
private TestRestTemplate template;
@ParameterizedTest
@MethodSource(names = "vehicles")
void nonRegressionTests(EDIVehicle vehicle) {
ResponseEntity<Vehicle> v = template.getForEntity("/match/" + vehicule.getId(), Vehicle.class);
Assert.assertNotNull(v);
}
private static Stream<EDIVehicle> vehicles() throws IOException {
InputStream is = new ClassPathResource("/entries.csv").getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(is));
return br.lines().map(toVehicle);
}
private static Function<String, EDIVehicle> toVehicle = (line) -> {
String[] p = line.split("\\|");
return new EDIVehicle(p[0], p[1], p[2], p[3], p[4], p[5], p[6], p[7], p[8], p[9], p[10], p[11], p[12]);
};
}
I know from the documentation that:
If you use @SpringBootTest annotation, TestRestTemplate is automatically available and can be @Autowired in your test.
The thing is, I am using SpringBootTest annotation, but when I run tests, TestRestTemplate is null all the time. I may have missed something.
EDIT: I have the same problem while adding @RunWith annotation (SpringRunner.class)

I ended up using a dependency on the following repo: github.com/sbrannen/spring-test-junit5 as @LucasP mentioned
Since there is no first class support for JUnit 5 in Spring 4.3 and below, this helped me autowiring the Spring TestRestTemplate correctly using @ExtendWith(SpringExtension.class)
in my test class.
The next step is to directly use Spring Boot 2.0 to better support JUnit 5.

@SpringBootTest
not fully compatible with JUnit 5. However, you can work around this by using the following test declaration:
@RunWith(JUnitPlatform.class)
@ExtendWith(SpringExtension.class)
@SpringBootTest(webEnvironment = RANDOM_PORT)
class MatchingIT {...}
Note. You must upgrade spring-boot-starter-test
to 2.0.0.M1
to use org.springframework.test.context.junit.jupiter.SpringExtension
(the easiest way: start.spring.io to create dependent 2.0.0.M1 project and obtain the necessary dependencies maven / gradle here).
