PICT

简介：

PICT（Pairwise Independent Combinatorial Testing ）工具原是微软公司内部使用的一款自动生成成对组合测试用例的命令行工具，现在对外提供，可以从互联网上下载到。

使用：

1.准备的文本文件(.txt) 内容包括(注意格式<ParamName> : <Value1>, <Value2>, <Value3>, ...)，e.g

OS:Win XP,Win 2003 server,Win7, Win NT4

Language:English,German,Chinese

CLR:Installed,not installed

MyApp:yes,no

IE:5.0,6.0,7.0,8.0,Firefox

2.在命令行下运行pict程序，如下；

也可以把输出结果重定向到一个文件，e.g E:\>pict cc.txt >result.txt

E:\>pict cc.txt

OS Language CLR MyApp IE

Win NT4 English Installed no Firefox

Win XP Chinese not installed yes 6.0

Win7 German not installed no 5.0

Win 2003 server English Installed yes 5.0

Win XP Chinese Installed no 7.0

Win NT4 German not installed yes 5.0

Win7 English Installed yes 7.0

Win 2003 server German not installed no 7.0

Win 2003 server Chinese not installed yes Firefo

Win NT4 German Installed yes 8.0

Win 2003 server English not installed no 8.0

Win7 Chinese not installed yes Firefox

Win XP English not installed yes 8.0

Win XP Chinese not installed no 5.0

Win7 German Installed no 6.0

Win NT4 Chinese not installed yes 7.0

Win XP German Installed yes Firefox

Win NT4 English Installed yes 6.0

Win7 Chinese Installed no 8.0

Win 2003 server English not installed no 6.0

3.更多的用法之约束条件

在有前提条件的情况下，如果MyApp的旧版本已经在目标机器上安装，那就说明CLR已经安装，那么就应该去掉MyApp：Yes和CLR：not installed这种不合逻辑的组合。e.g

OS:Win XP,Win 2003 server,Win7, Win NT4

Language:English,German,Chinese

CLR:Installed,not installed

MyApp:yes,no

IE:5.0,6.0,7.0,8.0,Firefox

#MyApp need CLR

if [MyApp] = “yes” then [CLR]=“Installed”;

4.更多的用法之子模型

一般用测试用例需要同时考虑硬件和软件组合的情况下，例如：

PLATFORM: x86, ia64, amd64

CPUS: Single, Dual, Quad

RAM: 128MB, 1GB, 4GB, 64GB

HDD: SCSI, IDE

OS: NT4, Win2K, WinXP, Win2K3

IE: 4.0, 5.0, 5.5, 6.0

APP: SQLServer, Exchange, Office

{ PLATFORM, CPUS, RAM, HDD } @ 3

{ OS, IE } @ 2

层次关系



5.子模型与约束条件结合

PLATFORM: x86, ia64, amd64

CPUS: Single, Dual, Quad

RAM: 128MB, 1GB, 4GB, 64GB

HDD: SCSI, IDE

OS: NT4, Win2K, WinXP, Win2K3

IE: 4.0, 5.0, 5.5, 6.0

{ PLATFORM, CPUS, RAM, HDD } @ 2

{ OS, IE } @ 2

IF [PLATFORM] in {"ia64", "amd64"} THEN [OS] in {"WinXP", "Win2K3"};

IF [PLATFORM] = "x86" THEN [RAM] <> "64GB";
