I wrote one test case for one class. it compilers and shows 0 error but the test cases are just 0 pass and 3 failure . Can anyone help me to fix it? I appreciate. Here's Original Class:

package synthpp; import processing.core.PApplet; import processing.core.PFont; import java.awt.Color; public class Button implements Clickable{ protected TextLabel text; protected PApplet pApplet; protected ButtonAdapter listener; protected boolean isPressed; protected boolean isDisabled; protected Color orginalForegroundColor;//used for mouseover effect  protected Color orginalBackgroundColor; public Button(PApplet pApplet, String t, PFont pFont, int w, int h, int x, int y, Color bg, Color fg){ this.pApplet = pApplet; text = new TextLabel(pApplet,t, pFont, x,y,w,h,TextLabel.HALIGN.center, TextLabel.VALIGN.center,0); text.setBackgroundColor(bg); text.setForegroundColor(fg); this.orginalBackgroundColor = bg; this.orginalForegroundColor = fg; isPressed = false; isDisabled = false; } public void draw(){ text.draw(); } //these 2 are used for highlighting with mouseover effect  public Color getOrginalForegroundColor(){ return this.orginalForegroundColor; } public Color getOrginalBackgroundColor(){ return orginalBackgroundColor; } public void setBackgroundColor(Color c){ text.setBackgroundColor(c); } public Color getBackgroundColor(){return text.getBackgroundColor();} public void setForgroundColor(Color c){ text.setForegroundColor(c); } public void addButtonListener(ButtonAdapter listener){ this.listener = listener; } @Override public boolean isPressed(){ return isPressed; } public boolean isDisabled(){ return isDisabled;} public void setDisabled(boolean d){ isDisabled = d;} @Override public void mousePressed(PApplet pApplet) { if(listener != null){ listener.mousePressed(pApplet); isPressed = true; } } @Override public void mouseReleased(PApplet pApplet) { if(listener != null && !isDisabled){ listener.mouseReleased(pApplet); isPressed = false; } } @Override public int getPosX() { return text.getPositionX(); } @Override public int getPosY() { return text.getPositionY(); } @Override public int getWidth() { return text.getWidth(); } @Override public int getHeight() { return text.getHeight(); } } 

Here's the test cases i wrote:
