-TestComplete
支持的测试类型

3.3
节中列举了
TC
支持的各种测试类型，包括：

（

1

）

Manual Testing

（手工测试）


Manual Testing is where a tester
methodically exercises the features of a product or product area without the
aid of test automation. The single greatest strength of manual testing is that
it is truly real-world testing, meaning that the tester can utilize the
application under test the same way an end user would.

Through manual testing the tester can
provide a wide variety of feedback about the application under test not limited
to simply reproducing bugs.

The major weakness of manual testing is
that it is time consuming, tedious and requires extended periods of very focused
attention which can be very difficult to perform on a regular basis. Manual testing
tends to be quite error prone, leading to situations where consistently
reproducing a bug can be very difficult.

 

（

2

）

Functional Testing

（功能测试）


Functional Testing focuses on
interactions with an application's user interface (UI) via the mouse, keyboard
or other input device with particular attention to how the application visually
responds to input.

The goal of Functional Testing is to
methodically cover all of the various UI features exposed by an application.
Functional Testing should be highly organized and structured in a manner that
allows for additional tests to easily be incorporated as new features are
added.

 

（

3

）

Unit Testing

（单元测试）


Unit Testing is testing that focuses on
smaller atomic portions of an application. Typically, Unit Testing requires
internal knowledge of how an application performs and seeks to test portions
(objects, methods and function) of an application in isolation. In many cases,
applications have to be designed with Unit Testing in mind in order for this
type of testing to be truly effective. The benefit of unit testing is that it tends
to force application developers to write smaller more well defined routines
with fewer dependencies allowing for more highly specific tests to be
developed.

 

（

4

）

Regression Testing

（回归测试）


Regression Testing is process of
executing tests in a repeatable manner and comparing the latest results with
previous test executions to ensure that the same outcome is achieved.
Regression Testing is extremely important and is the means of realizing the
value of test automation. Repeatedly executing tests over time allows you to
verify the application is still performing in the manner in which it was intended.

 

（

5

）

Distributed Testing

（分布式测试）


Distributed Testing is the act of farming
different portions of a test out to separate machines for execution.
Distributed Testing is useful for simulating real world interactions on a
networked application such as a web site or web service and can exercise
functionality designed to handle concurrent use of application resources
including, but not restricted to data.

 

（

6

）

HTTP Performance Testing

（

HTTP

性能测试）


HTTP Performance Testing is the
simulation of real-world interactions with a web application from multiple
machines. TestComplete provides the ability to leverage networked computers and
virtual users to simultaneously submit HTTP transactions to a web application.

 

TC
是目前市面上少有的以低廉的价格在一个工具内提供对多种类型测试支持的工具。

冒烟测试

 

冒烟测试是自动化测试中最重要，也最应该实现的测试。

The smoke test is crucial because of the time
savings it can provide both R&D and QA.

冒烟测试能为开发和
QA
节省大量的时间，一个好的冒烟测试应该：

·
快速运行
- a
smoke test should not last for hours but minutes and test the most crucial

functionality

·
快速发现错误并报告错误
-
as soon as a failure is detected in the smoke test should end and trigger a
failure notification

·
覆盖大范围的功能
-
Cover a broad range of functionality,
focusing on breadth not depth

·
需要的配置不多
-
Require minimal setup/configuration of
the application under test

·
对每个
Build
都运行冒烟测试
-
Be setup to run
against every build

·
需要随着被测试应用程序的修改而不断修改冒烟测试
-
Adapt over time as the application
under test evolves

·
作为新创建的自动化测试的基础模型
-
Serve as a model for new test
automation

白盒应用程序

 

TestComplete will be able to automatically see
deeply inside .NET and Java application without any changes to the application
just because of the nature of metadata generation of .NET and Java application
which are easy to reflect. Reflection is the ability to retrieve internal
objects, properties, methods and events. So these are always called
White Box

Applications.

 

.NET
和
Java
程序是基于中间代码构建的，所以
TC
可以直接通过反射读取其中的内部对象、属性、方法和事件。

 

Some Applications are written in C, C++ or
Delphi
,
these applications are mainly
Black
Box

applications but could be compiled in such a way to
enable them to become White Box Applications. That would require compiling with
Debug information enabled and the inclusion of some TestComplete files into the
project to enable reflection of all program metadata.

 

C
、
C++
、
Delphi
这类程序如果在编译时做相应的设置，则也可以变成
White Box Applications.

创建
Project

 

可通过
Project Wizard
创建测试项目，其中
Project Item
包括：

·
ActiveX

- This project
item allows you to load an ActiveX object in TestComplete's memory space and
use that object in your tests. For example you could use the Microsoft ADO Data
Control to work with databases.

·
Events

- This project
item is used to hook to TestComplete events (and those of other
application,such as ActiveX controls). This item is not required but is highly
recommended.

·
HTTP Load Testing

- Necessary for
the creation of a load on a web server using TestComplete.

·
Low-Level Procedure Collection

- A
virtual folder for holding low-level (screen coordinate based tests)
procedures.

·
Manual Test

- A virtual
folder for holding manual tests.

·
Name Mapping

- Used to map
the name of an object to a shorter name (aliasing).

·
Network Suite

- Used in
distributed testing.

·
ODT

- Object Driven
Testing used to add pseudo class structure to script code.

·
Script

- Holds a
collection of script units. THIS ITEM IS REQUIRED.

·
Stores

- Holds
collections of checkpoints used in a project

·
Unit Testing

- A virtual
folder for holding Unit Tests.

·
User Forms

- A virtual
folder for holding User Forms (Forms presented to the user during the test run,
such a progress dialog, etc).

·
Web Services

- A virtual
folder for holding connection, methods and type of web services

(Information from the WSDL file).

·
Win32 Tested Application

-
Holds information for managing the Application(s) under test.

 

其中

Win32 Tested Application


中可设置被测试应用程序的
Run Mode
，包括
4
种运行模式：

·
Simple

- Launches the
application under the same user account as TestComplete. Parameters can be
passed in Simple mode.

·
RunAs

- Launches the
application under the user account specified by the parameters dialog.

·
Debug

- Launches the
application under the same user account as TestComplete, then TestComplete
attaches to the application as a "debugger". The stack trace of any
exception that occurs in the application while the test(s) are being run will
be recorded in the TestLog. This option requires debug information in the
application under test.

·
Profile

- Launches the
application inside of AQTime using the profile (or AQTime project) specified in
the parameters dialog. For example code coverage profiling could be used to see
how much of the code is being tested by your automated tests.

 

一般都选择
Simple

，如果希望在
AQTime
下运行程序以便获得测试覆盖率、代码执行效率等信息的话则可选用
Profile


。

- Test Log

 

感觉
TC
的
Test Log
要比
QTP
的做得好些，
TC
的
Log
可以写
6
种类型的信息：

·
Message
- Can come from TestComplete or from the script code (Log.Message), will not
cause the test to fail.

·
Warning
- Can come from TestComplete or from the script code (Log.Warning), not
necessary a failure for the test but could be an indicator for why a test
failed.

·
Error
- Can come from TestComplete or from the script code (Log.Error), this
indicates a failure for the test.

·
Events
- Usually comes from TestComplete but can come from the script as well
(Log.Event), does not cause the test to fail. TestComplete generates an event
for every mouse-click or keyboard entry in the test.

·
Image
- Usually comes from script code (Log.Picture) but TestComplete can generate as
well (Region Checkpoints).

·
File
- There are two types of File log items. Log.File, will copy the file into the
directory holding the log XML file and creates a hyperlink to the file.
Log.Link just creates a hyperlink to the file without copying the file.

- Name Mappings

TC
没有像
QTP
一样的对象库以及对象库管理功能，但是对于那些“又长又臭”的代码行，可以通过
Named Mappings

和

Aliases


来缩短代码行，并且让测试对象的命名更加有意义，从而让录制和编写的脚本更加清晰、直观易懂。

 

TestComplete provides
Named Mappings

and
Aliases

to tame extremely long object identifiers that have meaningless default
names. For example:

Sys.Process(
"Hello"
).Panel1.Panel2.Container1.Container2.button1

 

Clearly there are numerous issues with
this identifier, its long and awkward not to mention we have no clue about the
purpose or identity of "Container1", "Container2" or
"button1".
Named Mappings

allow you to rename Panel1,
Panel2, Container1, Container2 and button1 to useful names like
MyPanel,myInsidePanel, myTabs, myPages and btnSubmit. The issue here is that
you still need to type:

NameMappings.Sys.Process("Hello").MyPanel.myInsidePanel.myTabs.myPages.btnSubmit

 

TestComplete lets you create an
Alias

to
represent this long string. If you create the Alias "btnSubmit",you
only need to type:

Aliases.btnSubmit

- Web
测试

 

TC
支持
4
种类型的
WEB
页面模型：

·
DOM

- Document
Object Model, the native way that Internet Explorer looks at web pages. The DOM
model creates a very flat tree in the Object Browser. All items on the web page
need to be re-read each time the web page is updated. This is the slowest
method for using web pages.

·
TAG

- All HTML
elements are sorted by their TAG value. If a link (<A> HTML tag) gets
created, only the "A" node part of the Object Browser tree gets
updated.

·
Tree

- Treats a web
page like a normal application. This model creates a very deep tree for most web
pages. This is the fastest method for using web pages.

·
Hybrid

- This uses
both DOM and Tree. All new recording will use the Tree model, while any old TestComplete
code using the DOM will continue to work.

TC
中可创建两种专门针对
WEB
的

-
The whole HTML page is save and is compared.

·
Compare only tab structure

-
Only tag names are compared, not attributes, attributes' values and elements'
values.

·
Compare only specified tags

-
Only the selected elements will be compared.

o
Compare links

- Only A
elements are compared (text and attributes of the element are compare as well).

o
Compare images

- Only IMG
elements are compared.

o
Compare input elements

- Only INPUT
elements are compare.

Web
Accessibility Checkpoint
：
verify accessibility compliance.

Web Accessibility Checkpoint
可检查以下方面的可访问性的遵循情况：

·
Check "alt" attribute

-
All IMG, APPLET, AREA and INPUT elements must have a non-empty ALT attribute.

·
Check "mailto:"

-
Web page must have at least one A element (link), whose HREF attribute starts
with mailto:

·
Check image sizes

- All IMG
elements must have the WIDTH and HEIGHT attributes specified.

·
Check "title" tag

-
The web page must have a non-empty TITLE elment.

·
Check tab indexes

- All INPUT,
SELECT, and TEXTAREA elements must have the TABINDEX attribute.

·
Check link accessibility

-
Checks for broken links.

·
Check ActiveX objects

-
Verifies there are no ActiveX objects on the web page.

·
Check Applet object

-
Verifies there are no Applet objects on the web page.

·
Check multimedia links

-
Verifies there are not AVI or SWF files on the web page.

·

Set

HTTPTask =
LoadTesting

.HTTPTaskByName("Task")

Set

VirtualUser =
LoadTesting

.CreateVirtualUser("VirtualUser1")

Set

VirtualUser.Task = HTTPTask

Call

VirtualUser.Run("Task")

End Sub


 

参数化的例子：

Sub

Test1

Dim

HTTPTask

Dim Request

Dim

VirtualUser

Set

HTTPTask =
LoadTesting

.HTTPTaskByName("Order")

Set

Request = HTTPTask.Connection(0).Request(0)

Randomize


Request.Variables.Item("paints")
= Int(1000 * Rnd()) + 1

Request.Variables.Item("pencils")
= Int(1000 * Rnd()) + 1

Request.Variables.Item("albums")
= Int(1000 * Rnd()) + 1

Set

VirtualUser =
LoadTesting

.CreateVirtualUser("VirtualUser1")

Set

VirtualUser.Task = HTTPTask

Call

VirtualUser.Run("Order")

End Sub


 

也可以在
OnLoadTestingRequest

事件中进行参数化，例如：

Sub

Test1

Dim

HTTPTask

Dim

VirtualUser

Set

HTTPTask =
LoadTesting

.HTTPTaskByName("Task")

HTTPTask.Connection(0).Request(0).RequestEventTrigger
= True

Set

VirtualUser =
LoadTesting

.CreateVirtualUser("VirtualUser1")

Set

VirtualUser.Task = HTTPTask

Call

VirtualUser.Run("Task")

End Sub


 

Sub

GeneralEvents_OnLoadTestingRequest(Sender,
User, Request)

Request.Variables.Item("paints")
= Int(1000 * Rnd()) + 1

Request.Variables.Item("pencils")
= Int(1000 * Rnd()) + 1

Request.Variables.Item("albums")
= Int(1000 * Rnd()) + 1

End Sub

分布式测试

 

TC
通过
Network Suites
来支持分布式测试。

 

什么是分布式测试：
Distributed
Testing is the ability of TestComplete to control test cases running on several
computers at the same time.

 

创建分布式测试需要注意：

（
1
）
In order to
perform a distributed test, all projects involved must contain the Network
Suite project item.

（
2
）
all the
computers involved must have the same version of TestComplete/TestExecute on
them (including the minor version number).

 

同步点：
SynchPoints
delay execution of the test until all computers with that synch point name
reach the synchronization point. When all the computers with a named SynchPoint
hit that Synchronize Point, they will continue on with their test.

 

如果希望模拟多个用户同时编辑一条记录的情况，则可以使用
SynchPoints
。
