軟件工程第五次作業

回答下列問題。

(1)什麼是模塊測試和集成測試?它們各有什麼特點?
(2)假設有一個由1 000行FORTRAN語句構成的程序(經編譯後大約有5 000條機器指令),估計在對它進行測試期間將發現多少個錯誤?爲什麼?
(3)設計下列僞碼程序的語句覆蓋和路徑覆蓋測試用例:

START
INPUT (A,B,C)
IFA>5
    THEN X= 10
    ELSE X= 1
END IF
IF B> 10
    THEN Y=20
    ELSE Y= 2
END IF
IF C> 15
    THEN Z= 30
    ELSE Z=3
END IF
PRINT (X,Y,Z)
STOP

解題

開始測試

• 語句覆蓋
  • [(A = 6, B = 11, c = 16), (x = 10, y = 20, z = 30)] Sabolegh
• 判定覆蓋
  • I [(A = 6, B = 11, c = 16), (x = 10, y = 20, z = 30)] Sabolegh
  • II [(A = 5, B = 10, c = 15), (x = 1, y = 2, z = 3)] Sabolegh
• 條件覆蓋
• 判定，條件覆蓋
• 條件組合覆蓋
  • I [(A = 6, B = 11, c = 16), (x = 10, y = 20, z = 30)] Sabolegh
  • II [(A = 5, B = 10, c = 15), (x = 1, y = 2, z = 3)] Sabolegh
• 路徑覆蓋

• A > 5, B > 10, C > 15

  • [(A = 6, B = 11, C = 16),(X = 10, Y = 20, Z = 30)] Sabolegh

• A <= 5, B > 10, C > 15

  • [(A = 5, B = 11, C = 16),(X = 1, Y = 20, Z = 30)] Sabolegh

• A > 5, B <= 10, C > 15

  • [(A = 6, B = 11, C = 16),(X = 10, Y = 2, Z = 30)] Sabolegh

• A <= 5, B <= 10, C > 15

  • [(A = 5, B = 10, C = 16),(X = 1, Y = 2, Z = 30)] Sabolegh

• A > 5, B > 10, C <= 15

  • [(A = 6, B = 11, C = 15),(X = 10, Y = 20, Z = 3)] Sabolegh

• A > 5, B <= 10, C <= 15

  • [(A = 6, B = 10, C = 15),(X = 10, Y = 2, Z = 3)] Sabolegh

• A <= 5, B > 10, C <= 15

  • [(A = 5, B = 11, C = 15),(X = 1, Y = 20, Z = 3)] Sabolegh

A <= 5, B <= 10, C <= 15
* [(A = 5, B = 11, C = 15),(X = 1, Y = 2, Z = 3)] Sabolegh
