JUnit测试用例不断失败-toString

Question

Not quite sure why this is failing, worked fine on a previous class/test pair.

Test:

@Test
public void testToString() {
    OrderLine o = new OrderLine("Tuna 4 pack", 399 , 2);
    String toStr = o.toString();

    assertTrue("The toString method should be in the standard convention format", 
            toStr.startsWith("OrderLine:[") && 
            toStr.contains("=" + o.getId() + ", ") &&
            toStr.contains("=" + o.getUnitPrice() + ", ") &&
            toStr.endsWith("=" + o.getQuantity() + "]"));
}

Class Function:

public String toString()
{
    return ("OrderLine:[ ID = " + id +
            ", UnitPrice = " + unitPrice +
            ", Quantity = " + quantity + 
            "]");

}

Apologies if the answer to this is really obvious, its been grating me for some time and I don't exactly have any fellow students I can ask for help right now.

Answer 1

Thanks!

I had no idea that the spaces AFTER the equals mattered as my mind just seems to have read that they were irrelevant. I only put them there for the purpose of readability (my mistake I know)

This is the rectified code oO

return ("OrderLine:[ID =" + id + 
        ", UnitPrice =" + unitPrice + 
        ", quantity =" + quantity + 
        "]");
