spring boot 1.4, spock and application.properties - spring-boot

Question

I am trying to write some tests for my Spring Boot 1.4.0 with Spock and my application-test-properties file is not being picked up.
I have this in my gradle:
dependencies {
compile('org.springframework.boot:spring-boot-starter-data-jpa')
compile('org.springframework.boot:spring-boot-starter-security')
compile('org.springframework.boot:spring-boot-starter-web')
compile 'org.codehaus.groovy:groovy-all:2.4.1'
testCompile('org.springframework.boot:spring-boot-starter-test')
testCompile('org.spockframework:spock-spring:1.0-groovy-2.4') {
}
Then I have this in
/src/test/groovy/resources:
# JWT Key
jwt.key=MyKy#99
And finally my Spock test:
#SpringBootTest(classes = MyApplication.class, webEnvironment=SpringBootTest.WebEnvironment.RANDOM_PORT)
#TestPropertySource("application-test.properties")
public class TokenUtilityTest extends Specification {
#Autowired
private TokenUtility tokenUtility
def "test a valid token creation"() {
def userDetails = new User(username: "test", password: "password", accountNonExpired: true, accountNonLocked: true,
);
when:
def token = tokenUtility.buildToken(userDetails)
then:
token != null
}
}
Which is testing this class:
#Component
public class TokenUtility {
private static final Logger LOG = LoggerFactory.getLogger( TokenUtility.class );
#Value("${jwt.key}")
private String jwtKey;
public String buildToken(UserDetails user) {
return Jwts.builder()
.setSubject(user.getUsername())
.signWith(SignatureAlgorithm.HS512, jwtKey)
.compact();
}
public boolean validate(String token) {
try {
Jwts.parser().setSigningKey(jwtKey).parseClaimsJws(token);
return true;
} catch (SignatureException e) {
LOG.error("Invalid JWT found: " + token);
}
return false;
}
}
I originally instantiated the TokenUtility on my test but the application-test.properties was never loaded (I am assuming since jwtKey was null). So I am trying #Autowired my class under test, but now that is null.
It looks like Spring Boot 1.4 changed a lot for testing, so perhaps I am not wiring this up correctly?

There are several things wrong with your test code; first, your dependencies are bad - Spock 1.0 does not support #SpringBootTest annotation so no context will be initialized and no post-processing will be done, hence the null pointer exception: nothing will be autowired.
Support for that annotation was added in Spock 1.1, which is still release-candidate, so you'll have to use that:
dependencies {
compile('org.springframework.boot:spring-boot-starter-data-jpa')
compile('org.springframework.boot:spring-boot-starter-security')
compile('org.springframework.boot:spring-boot-starter-web')
compile group: 'io.jsonwebtoken', name: 'jjwt', version: '0.6.0'
compile('org.codehaus.groovy:groovy')
testCompile('org.springframework.boot:spring-boot-starter-test')
testCompile('org.spockframework:spock-core:1.1-groovy-2.4-rc-1')
testCompile('org.spockframework:spock-spring:1.1-groovy-2.4-rc-1')
testCompile group: 'com.h2database', name: 'h2', version: '1.4.192'
}
Then, your path to the application-test.properties is wrong and should be /application-test.properties since it is in the root of the classpath:
#SpringBootTest(classes = DemoApplication.class,
webEnvironment = WebEnvironment.RANDOM_PORT)
#TestPropertySource("/application-test.properties")
public class TokenUtilityTest extends Specification {
#Autowired
TokenUtility tokenUtility
def "test a valid token creation"() {
def userDetails = new User("test", "password", Collections.emptyList());
when:
def token = tokenUtility.buildToken(userDetails)
then:
token != null
}
}

I had the similar problem, but for me, the solution was to change double quotes ".." to single quotes '..' inside the #Value annotation when working with Spock. Please find the example below:
#Value('${jwt.key}')
private String jwtKey;
PS - This is not the exact answer to the question. I am posting this for someone who faces a similar problem like mine and ends up here.
