LinkParameter { @Override public String toString() { StringBuilder sb = new StringBuilder(); sb.append("class LinkParameter {\n"); sb.append("}"); return sb.toString(); } LinkParameter(); String getValue(); void setValue(String value); LinkParameter value(String value); @Override boolean equals(java.lang.Object o); @Override int hashCode(); java.util.Map<String, Object> getExtensions(); void addExtension(String name, Object value); void setExtensions(java.util.Map<String, Object> extensions); LinkParameter extensions(java.util.Map<String, Object> extensions); @Override String toString();  }### Answer:
@Test public void testToString() { LinkParameter linkParameter = new LinkParameter(); linkParameter.setValue("foo"); Assert.assertEquals(linkParameter.toString(), "class LinkParameter {\n}"); }
