I have written a simple class and test it manually in main() and works as expected:
import org.nd4j.linalg.api.ndarray.INDArray;
import org.nd4j.linalg.factory.Nd4j;
public class ND4J {
public static void main(String[] args) {
ND4J actualObject = new ND4J(Nd4j.zeros(2,2).add(4.0));
INDArray testObject = Nd4j.create(new double[][]{{4.0,4.0}, {4.0,4.0}});
if(testObject.equals(actualObject.getMatrix())){
System.out.println("OK"); // prints “OK”
}
}
private INDArray matrix;
public ND4J (INDArray matrix){
this.matrix = matrix;
}
public INDArray getMatrix(){
return this.matrix;
}
public String toString(){
return this.getMatrix().toString();
}
}
But trying to unit test this class with JUnit 4 is throwing java.lang.AbstractMethodError:
import org.junit.Test;
import org.junit.runner.RunWith;
import org.nd4j.linalg.api.ndarray.INDArray;
import org.nd4j.linalg.factory.Nd4j;
import static org.junit.Assert.*;
public class ND4JTest {
@Test
public void print() {
ND4J actualObject = new ND4J(Nd4j.zeros(2,2).add(4.0));
//above statement throws this error
//java.lang.AbstractMethodError: org.nd4j.linalg.factory.Nd4jBackend.getConfigurationResource()Lorg/springframework/core/io/Resource;
INDArray testObject = Nd4j.create(new double[][]{{4.0,4.0}, {4.0,4.0}});
assertEquals(testObject, actualObject.getMatrix());
}
}
In fact more complex classes classes using ND4J that run fine from main() are having similar problems in testing. My pom file has the following ND4J dependencies: javacpp, nd4j-jblas, nd4j-native-platform, nd4j-native.
Thanks
