### Question:
AbstractValueSpecifier implements ValueSpecifier<B> { @Override public final B value(String value) { setValue(value); return builder; } protected  AbstractValueSpecifier(B builder, Attribute.Name name); @Override final B value(String value); @Override final B value(Integer value); @Override final B value(Double value); @Override final B value(Boolean value); @Override final B value(Instant value); @Override B value(Object value, TypeConverter.Conversion<T> converter);  }### Answer:
@Test public void testAbstractValueSpecifierWithBoolean(){ ValueBuilder valueBuilder = new ValueBuilder(); String name = "attr-name"; ValueBuilder builder = valueBuilder.withAttribute(Attribute.Name.valueOf(name)).value(true); assertNotNull(builder); }
@Test public void testAbstractValueSpecifierWithString(){ ValueBuilder valueBuilder = new ValueBuilder(); String name = "attr-name"; ValueBuilder builder = valueBuilder.withAttribute(Attribute.Name.valueOf(name)).value("test-value"); assertNotNull(builder); }
@Test public void testAbstractValueSpecifierWithInteger(){ ValueBuilder valueBuilder = new ValueBuilder(); String name = "attr-name"; ValueBuilder builder = valueBuilder.withAttribute(Attribute.Name.valueOf(name)).value(1); assertNotNull(builder); }
@Test public void testAbstractValueSpecifierWithDouble(){ ValueBuilder valueBuilder = new ValueBuilder(); String name = "attr-name"; Double dbl = 1.5; ValueBuilder builder = valueBuilder.withAttribute(Attribute.Name.valueOf(name)).value(dbl); assertNotNull(builder); }
@Test public void testAbstractValueSpecifierWithInstant(){ ValueBuilder valueBuilder = new ValueBuilder(); String name = "attr-name"; ValueBuilder builder = valueBuilder.withAttribute(Attribute.Name.valueOf(name)).value(Instant.EPOCH); assertNotNull(builder); }
@Test public void testAbstractValueSpecifierWithObjectTypeConversion(){ ValueBuilder valueBuilder = new ValueBuilder(); String name = "attr-name"; Object value = "attr-value"; @SuppressWarnings("unchecked") Conversion<String> converter = new StringTypeConversion(); ValueBuilder builder = valueBuilder.withAttribute(Attribute.Name.valueOf(name)).value(value, converter); assertNotNull(builder); }
