### Question:
ProducibleConfig { @Override public String toString() { return new StringBuilder(MIN_LENGTH).append(getClass().getSimpleName()) .append(" [steps=") .append(steps) .append(", width=") .append(width) .append(", height=") .append(height) .append("]") .toString(); } ProducibleConfig(int steps, int width, int height); static ProducibleConfig imports(Configurer configurer); static ProducibleConfig imports(Xml root); static Xml exports(ProducibleConfig config); int getWidth(); int getHeight(); int getSteps(); @Override int hashCode(); @Override boolean equals(Object object); @Override String toString(); static final String NODE_PRODUCIBLE; static final String ATT_STEPS; }### Answer:
@Test void testToString() { final ProducibleConfig producible = new ProducibleConfig(1, 2, 3); assertEquals("ProducibleConfig [steps=1, width=2, height=3]", producible.toString()); }
