(return to Date:testdate)
以下是用2008年4月30日实例化的更有意思的MM－路径： testIt<2>
msg2
Date:testdate.increment<8,9> msg7 Day:d.increment<28,29> ’now Day.d.currentPos=31 msg17 Month:m.getMonthSize<41,42> msg20 Year:y.isleap<60,61,63,64> ‘not a leap year (return to Month:m.getMonthSize)
class Day isA calendarUint
Private month m 21 22 Day(pDay,Month pMonth) setDay(pDay,pMonth) msg15

面向对象软件的ＭＭ－路径
面向对象软件中的MM-路径是由消 息连接起来的方法执行序列。 原子功能（ASF）是一种MM-路径， 从输入端口事件开始，到输出端口事件 结束。
o-oCalendar应用程序的伪代码如下：
class CalendarUnit ‘abstract class currentPos As Integer a setCurrentPos(pCurrentPos) b currentPos=pCurrentPos End ‘setCurrentPos
End’testIt
Class Date private Day d private Month m private Year y 4 5 6 7 Date(pMonth,pDay,pYear) y=instantiate Year(pYear) m=instantiate Month(pMonth,y) d=instantiate Day(pDay,m) End 8 9 10 11 „Date constructor msg4 msg5 msg6
(return to Date:testdate)
Date:testdate<6> msg5 Month:m<34,35> msg18
Month:m:setMonth<36,37> msg19
Month:m.setCurrentPos<a,b>
(return to Month:m.setMonth) (terurn to Month:m)
testIt
Date:testdate
1:printDate()
Day:d
Month:m
Year:y
2:getMonth()
3:getDay()
时间
4:getYear()
printDate的序列图
这种序列图的实际测试应该采用与以下类似的伪代码： 1. testDriver 2. m.setMonth(1) 3. d.setDay(15) 4. y.setYear(2002) 5. Output(“expected value is 1/15/2002”) 6. Output(“actual output is”) 7. test.printDate() 8. End testDriver
39
40 End 41
getMonth()
return currentPos „getMonth getMonthSize()
42
43 44 45 46 End 47 48 49 50
if(y.isleap())
Then sizeIndex[1]=29 Else sizeIndex[1]=28 EndIf rturn sizeIndex[currentPos-1] ‘getMonthSize boolean increment() currentPos=currentPos+1 if(currentPos>12) Then return flase
m20 m21
m14
increment() getYear isLeap
图18-3 o-oCalendar中的消息
2008年1月15日实例化Date的部分ＭＭ－路径：
testIt<1> msg1 Date:testdate<4,5> msg4 Year:y<53,54>
msg21
Year:y.setCurrentPos<a,b> (terurn to Year.y)
Month
1:getMonthSize
Day
o-oCalendar的协同图
根据协同图，可以得到以下要集成的类对： •testIt和Date，为Year、Month和Day建立桩。 •Date和Year，为testIt、Month和Day建立桩。 •Date和Month，为testIt、Year和Day建立桩。 •Date和Day，为testIt、Month和Year建立桩。 •Year和Month，为Date和Day建立桩。 •Month和Day，为Date和Year建立桩。
