Cannot run Robolectric tests with Gradle and Android Studio - StyleData not found - java

I downloaded deckard-gradle project and I have created my own with this temple.
My problem is that Robolectric.2.3 does not want to run test for class.
This is my error:
java.lang.RuntimeException: huh? can't find parent for StyleData{name='AppTheme', parent='Theme_AppCompat_Light_DarkActionBar'}

I run into similar problem, RobolectricTestRunner can't find the Android library dependencies. To resolve this issue you need to extend from RobolectricTestRunner to pull them in.android-maven-plugin unpacks your APK dependencies depending on version of the plugin into "target/unpack/apklibs" or to "target/unpacked-libs". The example I pasted below resolve problem for second one.
public class MyTestRunner extends RobolectricTestRunner {
public MyTestRunner(Class<?> testClass) throws InitializationError {
super(testClass);
}
#Override
protected AndroidManifest createAppManifest(FsFile manifestFile, FsFile resDir, FsFile assetsDir) {
return new MavenAndroidManifest( manifestFile, resDir, assetsDir);
}
public static class MavenAndroidManifest extends AndroidManifest {
public MavenAndroidManifest(FsFile androidManifestFile, FsFile resDirectory, FsFile assetsDirectory) {
super(androidManifestFile, resDirectory, assetsDirectory);
}
public MavenAndroidManifest(FsFile libraryBaseDir) {
super(libraryBaseDir);
}
#Override
protected List<FsFile> findLibraries() {
// Change "target/unpacked-libs" to "target/unpack/apklibs"
//if youe have older version of android-maven-plugin
FsFile unpack = getBaseDir().join("target/unpacked-libs");
if (unpack.exists()) {
FsFile[] libs = unpack.listFiles();
if (libs != null) {
return Arrays.asList(libs);
}
}
return Collections.emptyList();
}
#Override
protected AndroidManifest createLibraryAndroidManifest(FsFile libraryBaseDir) {
return new MavenAndroidManifest(libraryBaseDir);
}
}
}
Later in test cases use it like this:
#RunWith(MyTestRunner.class)
#Config(emulateSdk = 18)
public class MyActivityTest{
}

Apache Commons FileUtils.copyURLToFile - Directory that already exists could not be created

I'm attempting to download a JSON file and save it to a local directory. The directory (/data/provisioning) already exists and has been given 776 (u=rwx,g=rwx,o=rw) as its permissions. The parent directory (/data) has also been given 776 permissions.
I'm using the Apache Commons FileUtils.copyURLToFile(..) method to download the file, like this:
String filePathToSave = "/data/provisioning/nexus_contents.json";
String url = "http://repository.obfuscated.com/nexus/url/to/json/file";
try {
FileUtils.copyURLToFile(
new URL(url)
, new File(filePathToSave),
5000,
5000);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
However, to my surprise, I'm getting this error:
java.io.IOException: Directory '/data/provisioning' could not be
created at

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.

Spring Security Test fails with NullPointerException

Using Spring Security 3.2.5 and Spring Secuirty Test 4.0.0.M1 artifact, I am not able to run the following unit test successfully:
#Test

ClientRequest, how to serialize POJO's to json data correctly? could not find writer for content-type application/json type:

For a REST serives (RESTeasy) I have created JUnit test cases like:
#Test
public void a100_insertAddressTest() throws Exception {
Address addr = new Address(1, "testStreet", "1", (short) 1234,
"testCity");
ClientRequest request = new ClientRequest(BASE_URL + "customerID/{id}",
sslExecutor_schusb);
request.body(MediaType.APPLICATION_XML, addr).pathParameter(
"id", 1);
ClientResponse<String> response = request.post(String.class);
Assert.assertEquals(201, response.getStatus());
response.releaseConnection();
request.clear();
}
If I change the media type of the request body to "application/json", the test case fails with the error:

Hence I created a MessageBodyWriter which works fine if I do a POST request by using the firefox plugin RESTClient:
#Provider
#Produces(MediaType.APPLICATION_JSON)
public class JsonMsbWriter implements MessageBodyWriter<Address> {
#Override
public boolean isWriteable(Class<?> type, Type genericType,
Annotation[] annotations, MediaType mediaType) {
if(type == Address.class){
return true;
}
return false;
}
#Override
public long getSize(Address t, Class<?> type, Type genericType,
Annotation[] annotations, MediaType mediaType) {
return -1;
}
#Override
public void writeTo(Address t, Class<?> type, Type genericType,
Annotation[] annotations, MediaType mediaType,
MultivaluedMap<String, Object> httpHeaders,
OutputStream entityStream) throws IOException,
WebApplicationException {
ObjectMapper m = new ObjectMapper();
m.writeValue(entityStream, t);
}
}
and updated the JUnit test case to:
#Test
public void a100_insertAddressTest() throws Exception {
Address addr = new Address(1, "testStreet", "1", (short) 1234,
"testCity");
ResteasyProviderFactory fact = ResteasyProviderFactory.getInstance();
fact.addMessageBodyWriter(JsonMsbWriter.class);
ClientRequest request = new ClientRequest(BASE_URL + "customerID/{id}",
sslExecutor_schusb);
request.body(MediaType.APPLICATION_JSON, addr).pathParameter("id", 1);
ClientResponse<String> response = request.post(String.class);
Assert.assertEquals(201, response.getStatus());
response.releaseConnection();
request.clear();
}
But now I get the error:
java.lang.VerifyError: (class: org/codehaus/jackson/map/ObjectMapper, method: writeValueAsBytes signature: (Ljava/lang/Object;)[B) Incompatible argument to function

How can I attach such a writer for json?
And why does it work for content type application/xml out of the
box?
For GET requests and application/json there is the same problem, however with the reader instead of the writer.

Problem solved, unfortunately I haven't included all necessary 3rd party libraries to the projects build path. Finally I added the following jars:
jackson-core-asl-1.6.3.jar
jackson-jaxrs-1.6.3.jar
jackson-mapper-asl-1.6.3.jar
jackson-xc-1.6.3.jar
resteasy-jackson-provider-2.2.1.GA.jar
This example brings the strength of Maven to the front. With Maven there is only one entry necessary to fulfill these dependencies.
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jackson-provider</artifactId>
<version>2.2.1.GA</version>
</dependency>
