Test execution in Spring Boot fails due to failed config load - unit-testing

I am trying to test my application and running into troubles:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(classes = MainConfiguration.class)
public class ProductionDataRestClientTest {
#Test
public void testGetProductionDataAsync() {
}
}
The MainConfiguration class is as follows:
#Data
#Configuration
#Slf4j
#PropertySource(value = {
"classpath:/conf/application.properties", "classpath:/conf/application.build.properties",
"file:${configPath}/application.properties" }, ignoreResourceNotFound = true)
public class MainConfiguration {
#Value("${app.configName}")
private String configName;
#Value("${project.name}")
private String appName;
#Value("${project.version}")
private String appVersion;
#Value("${app.historySize}")
private int historySize;
#Value("${app.processOnlyVisibleEnvironments}")
private Boolean processOnlyVisibleEnvironments;
#PostConstruct
private void logConfig() {
appName = WordUtils.capitalize(appName);
log.info("constructed config: " + configName);
log.info(this.toString());
}
}
And the application.properties file is here:
app.configName=Internal Classpath
app.historySize=25
app.processOnlyVisibleEnvironments=true
client.timeout.connect=30000
client.timeout.read=30000
threading.pool.size.environmentProcessing=5
threading.pool.size.webServiceRequesting=10
My problem is, that Spring seems not to resolve the value identifiers as in normal executions, so the following stacktrace is thrown:
Caused by: java.lang.NumberFormatException: For input string: "${app.historySize}"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
at java.lang.Integer.parseInt(Integer.java:569)

... 47 more
I don't have any clue, I tried many different things, nothing worked.
Thanks in advance :)

There was a very simple way to solve this issue:
// To resolve ${} in #Value
#Bean
public static PropertySourcesPlaceholderConfigurer propertyConfigInDev() {
return new PropertySourcesPlaceholderConfigurer();
}
This has to be a method of the loaded Configuration-file and helps resolving the placeholders.
Thanks for helping ;)

How to write unit test for spring cloud stream function based method?

When I try to test a spring cloud stream function based method, it always happens NullPointerException about InputDestination.
I have two questions:
It's hard for me to know how to write UT from the official doc. official test doc
Besides, how to write integration Test if test file has some dependencies. It seems create a new context and always has NoSuchBeanDefination error.
I have tried as flow, but the context can not find some dependency beans.
#Test
public void sampleTest() {
try (ConfigurableApplicationContext context = new SpringApplicationBuilder(
TestChannelBinderConfiguration.getCompleteConfiguration(
MyTestConfiguration.class))
.run("--spring.cloud.function.definition=uppercase")) {
InputDestination source = context.getBean(InputDestination.class);
OutputDestination target = context.getBean(OutputDestination.class);
source.send(new GenericMessage<byte[]>("hello".getBytes()));
assertThat(target.receive().getPayload()).isEqualTo("HELLO".getBytes());
}
}
So I just want to write UT, but still have NPE.
Here is my code.
#Bean
public Function<Message<List<DemoBean>>, Message<DemoBean>> findFirstBean( ){
return message -> {
List<DemoBean> demoBeans = message.getPayload();
return MessageBuilder.withPayload(demoBeans.get( 0 )).build();
};
}
Here is my test.
#SpringBootTest
#ActiveProfiles(profiles = "local")
#Import({ TestChannelBinderConfiguration.class})
class FunctionDemoTest {
#Autowired
private InputDestination inputDestination;
#Autowired
private OutputDestination outputDestination;
private FunctionDemo functionDemo;
// some dependency need to mock
private DemoService demoService;
#BeforeEach
void setUp() {
demoService = Mockito.mock( DemoService.class );
functionDemo = new FunctionDemo( demoService);
}
#Test
public void findFirstBeanTest() {
DemoBean demoBean = new DemoBean();
demoBean.setName("Howard");
demoBean.setAge( 1 );
DemoBean demoBean1 = new DemoBean();
demoBean1.setName("Frank");
demoBean1.setAge( 2 );
List<DemoBean> demoBeanList = new ArrayList<>();
demoBeanList.add( demoBean );
demoBeanList.add( demoBean1 );
Message<List<DemoBean>> inputMessage = MessageBuilder.withPayload(demoBeanList).build();
inputDestination.send(inputMessage,"findFirstBean-in-0");
Assertions.assertNotNull( outputDestination.receive( 10000, "findFirstBean-out-0") );
}
}
Here is error:
java.lang.NullPointerException: while trying to invoke the method org.springframework.messaging.SubscribableChannel.send(org.springframework.messaging.Message) of a null object returned from org.springframework.cloud.stream.binder.test.InputDestination.getChannelByName(java.lang.String)
at org.springframework.cloud.stream.binder.test.InputDestination.send(InputDestination.java:89)
at com.successfactors.caf.listener.FunctionDemoTest.raePdrResultProcessor(FunctionDemoTest.java:82)
Well, I know the root cause of NPE.
Message<byte[]> receive(long timeout, String bindingName)
It seems should be destinationName instead of bindingName in source code.
Any other answers would be appreciated.

Quarkus kubernetesMockServer for application initialization

I am working on a Quarkus application to acct as an Operator in a OpenShift/Kubernetes cluster. When writing the tests using a kubernetesMockServer it is working fine for REST calls to developed application but when code runs inside an Initialization Block it is failing, in the log I see that mock server is replying with a 404 error:
2020-02-17 11:04:12,148 INFO [okh.moc.MockWebServer] (MockWebServer /127.0.0.1:53048) MockWebServer[57577] received request: GET /apis/apiextensions.k8s.io/v1beta1/customresourcedefinitions HTTP/1.1 and responded: HTTP/1.1 404 Client Error
On the TestCode I have:
#QuarkusTestResource(KubernetesMockServerTestResource.class)
#QuarkusTest
class TestAIRController {
#MockServer
KubernetesMockServer mockServer;
private CustomResourceDefinition crd;
private CustomResourceDefinitionList crdlist;
#BeforeEach
public void before() {
crd = new CustomResourceDefinitionBuilder()
.withApiVersion("apiextensions.k8s.io/v1beta1")
.withNewMetadata().withName("types.openshift.example-cloud.com")
.endMetadata()
.withNewSpec()
.withNewNames()
.withKind("Type")
.withPlural("types")
.endNames()
.withGroup("openshift.example-cloud.com")
.withVersion("v1")
.withScope("Namespaced")
.endSpec()
.build();
crdlist = new CustomResourceDefinitionListBuilder().withItems(crd).build();
mockServer.expect().get().withPath("/apis/apiextensions.k8s.io/v1beta1/customresourcedefinitions")
.andReturn(200, crdlist)
.always();
}
#Test
void test() {
RestAssured.when().get("/dummy").then().body("size()", Is.is(0));
}
}
The dummy rest is using the same code for searching the CRD, and in fact when running withouth the class observing the startup event it works fine
#Path("/dummy")
public class Dummy {
private static final Logger LOGGER =LoggerFactory.getLogger(Dummy.class);
#GET
#Produces(MediaType.APPLICATION_JSON)
public Response listCRDs(){
KubernetesClient oc = new DefaultKubernetesClient();
CustomResourceDefinition crd = oc.customResourceDefinitions()
.list().getItems().stream()
.filter( ob -> ob.getMetadata().getName().equals("types.openshift.example-cloud.com"))
.findFirst().get();
LOGGER.info("CRD NAME is {}", crd.getMetadata().getName());
return Response.ok(new ArrayList<String>()).build();
}
}
Finally this is an except of the
#ApplicationScoped
public class AIRWatcher {
private static final Logger LOGGER = LoggerFactory.getLogger(AIRWatcher.class);
void OnStart(#Observes StartupEvent ev) {
KubernetesClient oc = new DefaultKubernetesClient();
CustomResourceDefinition crd = oc.customResourceDefinitions()
.list().getItems().stream()
.filter( ob -> ob.getMetadata().getName().equals("types.openshift.example-cloud.com"))
.findFirst().get();
LOGGER.info("Using {}", crd.getMetadata().getName());
}
}
It's like for some reason the mock server is still not initialized for the Startup event, is there any way to solve it?
The problem is that the Mock Server is only configured to respond right before the test execution, while this code:
void OnStart(#Observes StartupEvent ev) {
KubernetesClient oc = new DefaultKubernetesClient();
CustomResourceDefinition crd = oc.customResourceDefinitions()
.list().getItems().stream()
.filter( ob -> ob.getMetadata().getName().equals("types.openshift.example-cloud.com"))
.findFirst().get();
LOGGER.info("Using {}", crd.getMetadata().getName());
}
runs when the application is actually comes up (which is before any #BeforeEach runs).
Can you please open an issue on the Quarkus Github? This should be something we provide a solution for

Junit error - No value present or no such element

testclass.java
#Test
public void testgetDictionaryValueListById() {
DictionaryValue dictionaryValue = new DictionaryValue();
dictionaryValue.setId(1);
dictionaryValue.setValueName("Test Dictionary Value");
dictionaryValue.setValueKey("12345678");
dictionaryValue.setStatus("Active");
dictionaryValue.setCreatedOn(new Date());
dictionaryValue.setUpdatedOn(new Date());
Mockito.when(dictionaryValueRepo.findById(1).get()).thenReturn(dictionaryValue);
assertThat(dictionaryService.getDictionaryValueListById(1)).isEqualTo(dictionaryValue);
}
Service.java
public DictionaryValue getDictionaryValueListById(int id) {
return dictionaryValueRepo.findById(id).get();
}
Repo.java
#Repository
public interface DictionaryValueRepo extends JpaRepository<DictionaryValue, Integer> {
}
I am getting no such value present again and again on executing test case in testclass.java. I don't know why? but when I am running my service method from the controller it is working as expected - fetching records from the database but not working in a test case.
Your test should be like this and please check out the naming. You need to Mock the step findId() befor the `get().
#InjectMocks
Service cut;
#Mock
DictionaryValueRepo dictionaryValueRepoMock;
// Can skipped by adding a #RunWith... on Testclass
#Before
public init() {
Mockito.initMocks(this);
}
#Test
public void testgetDictionaryValueListById() {
// Prepare Data
final int testId = 1;
DictionaryValue dictionaryValue = new DictionaryValue();
dictionaryValue.setId(testId);
dictionaryValue.setValueName("Test Dictionary Value");
dictionaryValue.setValueKey("12345678");
dictionaryValue.setStatus("Active");
dictionaryValue.setCreatedOn(new Date());
dictionaryValue.setUpdatedOn(new Date());
// config mocking
Mockito.when(dictionaryValueRepo.findById(testId)).thenReturn(<VALUE>);
Mockito.when(dictionaryValueRepo.findById(testId).get()).thenReturn(dictionaryValue);
// Call yout method for Testing
cut.getDictionaryValueListById(testId);
// verifies (if wanted) + assertions....
}
I concur with LenglBoy, so the right answer should be given to him.
The thing you need to be careful is what "VALUE" means in this line:
Mockito.when(dictionaryValueRepo.findById(testId)).thenReturn(VALUE);
The findById returns an Optional, so that is what you should build and pass to Mockito. Something like this:
Mockito.when(dictionaryValueRepo.findById(testId))
.thenReturn(Optional.ofNullable(dictionaryValue));
And for a scenario where the id does not exists in BD, passing Optional.empty() should be good enough.

How can I override the test method name that appears on the TestNG report?

How can I override the test name that appears on the TestNG report? I want to override the name that appears in the middle column (currently shows as the method name). Is this even possible?
I tried to do it like this, but it didn't work.
public class EchApiTest1 extends TestBase {
...
#BeforeTest
public void setUp() {
restClient = new RestClientPost();
this.setTestName( "ech: XXXXXX" );
}
And, the base class:
import org.testng.ITest;
public class TestBase implements ITest {
String testName = "";
#Override
public String getTestName() {
return this.testName;
}
public void setTestName( String name ) {
this.testName = name;
}
}
NOTE: The above code does work when I am viewing the report detail in the Jenkins TestNG plugin report, which shows the overridden test name as a string called "Instance Name:" at the beginning of the Reporter log output. Why, in this case, WHY does a "setTestName()" method alter a string labeled "Instance Name" in the report?
One answer I found had a suggestion like this but I don't know how to pass an ITestResult arg to a AfterMethod method:
#AfterMethod
public void setResultTestName( ITestResult result ) {
try {
BaseTestMethod bm = (BaseTestMethod)result.getMethod();
Field f = bm.getClass().getSuperclass().getDeclaredField("m_methodName");
f.setAccessible(true);
f.set( bm, bm.getMethodName() + "." + your_customized_name );
} catch ( Exception ex ) {
Reporter.log( "ex" + ex.getMessage() );
}
Thoughts?
Please find following code for set custom name of testcase in TestNG reports.
Following features are available in this code.
Dynamic execution on same test-case in multiple time
Set custom test-case name for reports
Set parallel execution of multiple test-cases execution
import java.lang.reflect.Field;

System.out.println(this.serviceProcessData.toString());
}
#Factory(dataProvider = "processDataList")
public RiskServiceTest(ServiceProcessData serviceProcessData) {
this.serviceProcessData = serviceProcessData;
}
#DataProvider(name = "processDataList", parallel = true)
public static Object[] getProcessDataList() {
Object[] serviceProcessDataList = new Object[0];
//Set data in serviceProcessDataList
return serviceProcessDataList;
}
#Override
public String getTestName() {
this.testCaseName = "User custom testcase name";
// this.testCaseName = this.serviceProcessData.getTestCaseCustomName();
return this.testCaseName;
}
#AfterMethod(alwaysRun = true)
public void setResultTestName(ITestResult result) {
try {
BaseTestMethod baseTestMethod = (BaseTestMethod) result.getMethod();
Field f = baseTestMethod.getClass().getSuperclass().getDeclaredField("m_methodName");
f.setAccessible(true);
f.set(baseTestMethod, this.testCaseName);
} catch (Exception e) {
ErrorMessageHelper.getInstance().setErrorMessage(e);
Reporter.log("Exception : " + e.getMessage());
}
}}
Thanks
I found a "workaround" but I am hoping for a better answer. I want to be able to show this "test name" OR "instance name" value on the HTML report (not just within the Reporter.log output) and I am starting to think its not possible :
#Test(dataProvider = "restdata2")
public void testGetNameFromResponse( TestArguments testArgs ) {
this.setTestName( "ech: " + testArgs.getTestName() );
Reporter.log( getTestName() ); // this magic shows test name on report
....
With this workaround, the user can now identify which test it was by looking at the Reporter.log output but I still wish the name was more prominant.
I suspect the answer lies in writing a TestListenerAdapter that somehow overrides the ITestResult.getTestNameMethod() method? That is the holy grail I am looking for.
The ‘result’ object will automatically pass in the method setResultTestName( ITestResult result )
Make sure you put alwaysRun=true like the following when you have groups defined in your test class otherwise “AfterMethod” will not be excuted.
#AfterMethod (alwaysRun=true)

How do I invoke Multiple Startup Projects when running a unit tests in Debug Mode

This seems like a simple thing to do but I can't seem to find any info anywhere! I've got a solution that has a service that we run in 'Console Mode' when debugging. I want it to be started and 'attached' when I run my unit test from Visual Studio.
I'm using Resharper as the unit test runner.
Not a direct answer to your question, BUT
We faced a similar problem recently and eventually settled on a solution using AppDomain
As your solution is already running as a Console project it would be little work to make it boot in a new AppDomain. Furthermore, you could run Assertions on this project as well as part of unit testing. (if required)
Consider the following static class Sandbox which you can use to boot multiple app domains.
The Execute method requires a Type which is-a SandboxAction. (class definition also included below)
You would first extend this class and provide any bootup actions for running your console project.
public class ConsoleRunnerProjectSandbox : SandboxAction
{
protected override void OnRun()
{
Bootstrapper.Start(); //this code will be run on the newly create app domain
}
}
Now to get your app domain running you simply call
Sandbox.Execute<ConsoleRunnerProjectSandbox>("AppDomainName", configFile)
Note you can pass this call a config file so you can bootup your project in the same fashion as if you were running it via the console
Any more questions please ask.
public static class Sandbox
{
private static readonly List<Tuple<AppDomain, SandboxAction>> _sandboxes = new List<Tuple<AppDomain, SandboxAction>>();
public static T Execute<T>(string friendlyName, string configFile, params object[] args)

AppDomain sandbox = CreateDomain(friendlyName, configFile);
var objectHandle = sandbox.CreateInstance(typeof(T).Assembly.FullName, typeof(T).FullName, true, BindingFlags.Default, null, args, null, null, null);
T sandBoxAction = objectHandle.Unwrap() as T;
sandBoxAction.Run();
Tuple<AppDomain, SandboxAction> box = new Tuple<AppDomain, SandboxAction>(sandbox, sandBoxAction);
_sandboxes.Add(box);
return sandBoxAction;
}
private static AppDomain CreateDomain(string name, string customConfigFile)

FileInfo info = customConfigFile != null ? new FileInfo(customConfigFile) : null;

var appsetup = new AppDomainSetup();

customConfigFile = AppDomain.CurrentDomain.SetupInformation.ConfigurationFile;
