WireMock and Feign problem (Unit tests, Spring)

I'm trying to write some unit tests for few funcionts, which used feign to get information from another service. I try to use WireMock to do it but unfortunetely i get an exception like this :
feign.RetryableException: unexpected end of stream on http://localhost:8088/... executing POST http://localhost:8088/api

}
I think that this information is enaugh to know something about this problem (I could add that it works fine with real services so in my opinion problem is somewhere in MockServer configuration).

I think you forgot to close your resulting json
.withStatus(200).withBody("{\"token\":\"1234\"/n")))
should be
.withStatus(200).withBody("{\"token\":\"1234\"}/n")))

The solution was to change port of mock server.

Assertj-swagger throws org.assertj.core.error.AssertJMultipleFailuresError Multiple Failures when executing test

I have a spring boot api application and I used springfox to generate swaggerv2 api documentation and I created a test to see if my api definitions are correct.
Heres how my configuration looks like:
#Configuration
#EnableSwagger2
public class SpringFoxConfig {
#Value("${my.app.version}")
private String appVersion;
#Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2).groupName("My App").select()
.apis(RequestHandlerSelectors.basePackage("my.com.app.controller"))
.paths(regex("/api/MyAppName.*")).build()
.globalOperationParameters(
Arrays.asList(new ParameterBuilder().name("UserKey").description("Unique user key.")
.modelRef(new ModelRef("string")).parameterType("header").required(true).build()))
.apiInfo(apiInfo()).securitySchemes(Arrays.asList(apiKey()));
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder().title("My App API Documentaion")
.description("This documentation is for the MyApp.").version(appVersion)
.license("MyApp.cc").licenseUrl("https://myapp.com/").build();
}
private ApiKey apiKey() {
return new ApiKey("apiKey", "APIKEY", "header");
}
}
Here's how my test looks:
#Test
public void shouldFindNoDifferences() {
File implFirstSwaggerLocation = new File(
MyTest.class.getResource("/swagger.json").getFile());
File designFirstSwaggerLocation = new File(
MyTest.class.getResource("/swagger.yaml").getFile());
SwaggerAssertions.assertThat(implFirstSwaggerLocation.getAbsolutePath())
.isEqualTo(designFirstSwaggerLocation.getAbsolutePath());
}
It's exactly what they have from their examples. When I run my test It throws this exception below:

I think I'm missing something.

It was my carelessness that resulted to this problem but thanks to Roddy's comment I was able to notice my mistake.
In my assertj-swagger.properties file there contains assertj.swagger.pathsPrependExpected=/v2 property that causes this issue.

Arquillian RESTful Web Service Test - URL error

I'm doing some integration tests for a REST API I developed. I'm trying to use Arquillian but I can't seem to find that much information about tests on RESTful webservices. I just want to test that my API returns the right String. It's a currency converter, we give an input like "USD/10/EUR" and it converts, returning a String like "10 USD -> 8.21827744904668 EUR".
Right now, this is where I'm at with the test class:
#RunWith(Arquillian.class)
public class ExchangeRateTest {
#Deployment(testable = false)
public static JavaArchive createDeployment() {
return ShrinkWrap.create(JavaArchive.class)
.addPackage(ExchangeRate.class.getPackage())
.addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
}
#ArquillianResource
private URL base;
private static WebTarget target;
#Before
public void setUpClass() throws MalformedURLException {
Client client = ClientBuilder.newClient();
target = client.target(URI.create(new URL(base, "webresources/rates/USD/10/EUR").toExternalForm()));
}
#Test
#RunAsClient
public void testResponse(#ArquillianResource URL base) throws InterruptedException, ExecutionException {
try {
System.out.println("URL TARGET: " + target.getUri().toURL().toString());
} catch (MalformedURLException e) {
e.printStackTrace();
}
//assertEquals("10 USD -> 8.21827744904668 EUR", target.request().get().readEntity(String.class));
}
}
The following error appears:

This is my RESTful Webservice:
#Path("rates")
public class ExchangeRate {
private final CurrencyCalculator rates;
public ExchangeRate() {
rates = new CurrencyCalculator();
}
#GET
#Path("{from}/{amount}/{to}")
#Produces(MediaType.TEXT_PLAIN)
public String getRates(#PathParam("from") String from,#PathParam("amount")
String amount, #PathParam("to") String to) {
double value = 0;
try{
value = rates.convert(from, Double.parseDouble(amount), to);
}catch(RuntimeException e){
System.err.println("Currency is not available.");
}
return amount+" "+from+" -> "+value+" "+to;
}
}
I'd be more than happy if you could point me out my mistakes with the Test Class.

Error : java.lang.UnsatisfiedLinkError with roboelectric and realm

Hi I am using realm database for my application and using roboelectric unit testing framework for performing unit testing. I see realm is written in native c code, it has librealm-jni.so file for their functionality.
I am getting UnsatisfiedLinkError error, read somewhere that robolectric does not support native libraries. I believe that there must be some way to resolve it. I tried accepted answer of this How to load .so when using Robolectric? but no luck.
java.lang.UnsatisfiedLinkError: Can't load library: C:\Users\XS~1\AppData\Local\Temp\android-tmp-robolectric7796034244909642596\app_lib\realm-jni.dll.2.3.1

It is an open issue that Realm doesn't support Robolectric (yet).

Getting error java.lang.AbstractMethodError on ReportClientDocument.open() call

I am trying to autopost a crystal report in PDF formate.
I am using IDE: IntelliJ Gradle
public void runApprovedSupplierSiteReport(){
// final Config config = ConfigFactory.instance(Config.class);
//CrystalUtil.setupJdbcJndi(Config.getDatabaseServer(), Config.getDatabaseUsername(), Config.getDatabasePassword(), Config.getDatabaseJdbcDriver(), Config.getDatabaseJdbcUrl());
final List<String> paramNames = Config.getMatches(APPROVED_SUPPLIER_SITE_PARAM_REGEX);
final Map<String, String> params = new HashMap<>();
for (final String name : paramNames) {
final String value = Config.getPqp_Report_ApprovedSupplierSite_Param_$0_Value(name);
params.put(name, value);
}
final ReportClientDocument reportDoc = new ReportClientDocument();
try {
// export PDF
final String report = Config.getPqp_Report_ApprovedSupplierSite_Rpt();
reportDoc.open(report, OpenReportOptions._openAsReadOnly);
CrystalUtil.setParamFields(reportDoc, params);
final InputStream is = reportDoc.getPrintOutputController().export(ReportExportFormat.PDF);
//
final Session session = CmisUtil.createSession(Config.getPdmsAtomPubUrl(), Config.getPdmsUser(), Config.getPdmsPassword(), Config.getPdmsRepositoryId());
final Map<String, Object> properties = DocumentManager.getDocumentProperties(
DocType.SUPPLIER_REPORTS,
DocGroup.MQPSD,
SUPPLIER_REPORT_DOC_NUMBER,
SUPPLIER_REPORT_NAME,
new Date());
final String prefix = ConfigUtil.getEnvironmentPrefix(Config.getTwsEnvironmentCode());
final String docName = prefix + String.format(DocFormat.SUPPLIER_REPORTS, PdmsUtil.getDateAsString(new Date()));
final Document document = CmisUtil.createDocument(
session,
docName + ".pdf",
"",
docName,
DocClass.REPORTS,
MediaType.PDF.toString(),
is,
-1,
properties);
Monitor.getLogger().info("<- PDMS report=" + report + " id=" + document.getId() + " versionSeriesId=" + document.getVersionSeriesId());
} catch (final ReportSDKException e) {
String err = e.getMessage();
Monitor.getLogger().error("runApprovedSupplierSiteReport() " + e.getMessage());
logger.error("runApprovedSupplierSiteReport()", e);
} catch (final CmisBaseException e) {
Monitor.getLogger().error("runApprovedSupplierSiteReport() " + e.getErrorContent());
logger.error("runApprovedSupplierSiteReport()", e);
} finally {
CrystalUtil.closeQuietly(reportDoc);
}
}
In above code snippet at line reportDoc.open(report, OpenReportOptions._openAsReadOnly); I got following error :

I have checked for all abstract classes but all the methods are defined. Please let me know if anybody can help me in solving this error.

void com.businessobjects.reports.sdk.JRCCommunicationAdapter.setProductLocale(Locale)
This method is concrete in the version of the library you used to compile your code, so your IDE was happy to compile a call reference to it.
The library present in the deployment location is a different version in which this method is abstract.
This is described in the Javadoc for AbstractMethodError:
Thrown when an application tries to call an abstract method. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of some class has incompatibly changed since the currently executing method was last compiled.
