J unit testing failing when using picocli : test wont run  correctly

trying to run a junit test- errors

Please be kind fairly new to both java and picocli

package picocli;

import java.io.Serializable;

import picocli.CommandLine.Option;

public class ComparatorRunnerConfig implements Serializable{
	/** The output path. */

	  @Option(names = {"-o", "--output-parquet"}, required = false, description = "define output parquet path")

	  private String outputParquetPath;
	  
	  public String getOutputParquetPath() {

		    return outputParquetPath;

	  }
	  
	  @Option(names = {"-ic", "ingestorPath"}, required = false, description = "define ingestor  path")

	  private String ingestorPath;
	  
	  public String getingestorPath() {

		    return ingestorPath;
	  
	  }
	  
	  
	  
	  
	  @Option(names = {"-if", "--inputfile"}, required = false, description = "define input-file")

	  private String inputFile;
	  
	  public String getinputFile() {

		    return inputFile;
		    
	  }
	  
	  
	  
	  @Option(names = {"-rc", "--report-class"}, required = false, description = "define report")

	  private String report;
	  
	  public String getReport() {

		    return report;
		    
	  }
	  
	  @Option(names = {"-of", "--output-file"}, required = false, description = "define outputfile")

	  private String outputFile;
	  
	  
	  
	  public String getoutputFile() {

		    return outputFile;
		    
	  }
	  
	
	  
//Using the config in a main method:

	 

	  public static void main(String[] args) {

	    ComparatorRunnerConfig  config = new ComparatorRunnerConfig();

	    new CommandLine(config).parse(args);

	  }
	  
}


MY JUNIT TEST

package picocli;

import static org.junit.Assert.*;

import org.junit.Test;

public class ConfigurationTest {

	@Test
	public void testBasicConfigOptions() {
		String args = "-rc BlahBlah";
		ComparatorRunnerConfig mfc = new ComparatorRunnerConfig();
			new CommandLine( mfc ).parse(args);	
		String myTestValue = mfc.getReport();
		assertEquals("I expected the ComparatorRunnerConfig to have the value getReport but got: "+myTestValue, myTestValue, "BlahBlah");
	}

}
 



test fails
