eCATT- An Introduction
eCATT-Extended Computer Aided Test Tool

Introduction to eCATT.

The Extended Computer Aided Test Tool is a new automated testing tool that
allows you to create automated functional test cases for the majority of
applications running in the SAP GUI for Windows and SAP GUI for Java
environments. Like other test tools, it works by making a recording of an
application, which you can then parameterize and replay with differing sets of
input values. You can test the behavior of the application by reading and testing
the values returned by the application . eCATT is available from Release 6.20
of the SAP Web Application Server, and is an integral part of the mySAP
Technology underlying SAP R/3 Enterprise Release 4.7.
Designed as a successor to the existing CATT, it allows a user to record and
replay any application running under SAP GUI for Java or SAP GUI for
Windows. Furthermore, because it is embedded within the SAP application
server, it has access to other interfaces, such as function modules, BAPIs, or the
SAP database (so that users can perform checks), and the ABAP runtime, which
lets users write ABAP routines into test cases.

With SAP eCATT, users are also able to test business processes that cross
system boundaries. Each command in a test script can have a separate
destination so, within one script, a user can call a transaction in mySAP
Customer Relationship Management, and also check table entries in an SAP
R/3 system. Within a script, logical names are used to refer to target systems.
These logical names are mapped to actual RFC destinations in a separate object
called a system data container, which is, effectively, a description of the
company’s system landscape. Thus by linking a different system data container
with a script, a user can execute it in a completely different system landscape
without having to alter the script coding at all. The only prerequisite is that all
the logical system names that the script uses are defined in the relevant system
data container.
Because of the wide variety of applications that may need to be tested, eCATT
does not have a single "one-size-fits-all” way of recording and replaying
applications. Instead, there are various drivers that encompass the following
kinds of scenarios:

• Table operations– interacting with the SAP database
• Function modules and BAPIs
• ABAP
• Transactions and reports
• Applications running outside the SAP GUI for Windows or Java environments

For the last of these scenarios, eCATT offers an interface that third-party tool
manufacturers can implement to integrate their tools with eCATT.
You can migrate test cases from Computer Aided Test Tool (CATT) to take
advantage of the better features of eCATT.
eCATT is also integrated with the Object Navigator (SE80).

Features
Using eCATT we can:

• Test transactions, reports, and scenarios
• Call BAPIs and function modules
• Test remote systems
• Check authorizations (user profiles)
• Test updates (database, applications, GUI)
• Test the effect of changes to customizing settings
• Check system messages

Constraints
eCATT runs in a system based on SAP Web Application Server 6.20 or higher.
However, you can use this system to test systems with Release 4.6C or higher.

In my forth coming weblog’s I will be going through the following topics :

1. Creating Test Scripts .
2. Creating Test Data Containers .
3. Understanding System Data Containers .
4. Executing Test Configurations .
5. Understanding Logs .

I will also demonstrate the use of eCATT with following applications:
• Testing a Standard SAP Business Scenario .
• Testing a Web Dynpro Application .
• Migrating Test Cases from CATT to eCATT

eCATT: Creating Test Scripts
Understanding eCATT

Creation of Test Scripts

In my last weblog on “eCATT : An Introduction” I introduced the subject of
eCATT and discussed the capabilities and features of the same . In this weblog
I will be going a step further and explain the creation of Test Scripts , the first
step in the creation of Test Cases using eCATT .

Before creating Test Scripts using eCATT we need to have some system setting
done .

1. Maintaining Table T000
a. Start transaction SM31.
b. In the Table/View field, enter T000.
c. Choose Maintain.
d. In the Change View “Clients”: Overview screen, select the relevant client
and choose.
e. In the Restrictions when Starting eCATT field, select an entry that allows
eCATT.

2. Enabling Scripting at the front End .
( Check whether SAP GUI Scripting component is installed. There is an option
for installing this component when installing the SAP GUI.)
a. On any screen, choose Customizing of local layout.
b. Choose Options....
c. Choose the Scripting tab.
d. Select Enable Scripting.
e. Choose Apply.

3. Enabling Scripting on application server .
a. Start transaction RZ11.
b. On the Maintain Profile Parameters screen, enter sapgui/user_scripting.
c. Choose Display.
d. In the Display Profile Parameter Attributes screen, choose Change value.
e . Enter TRUE in the New value field.

Now we will start with creation of Test Scripts :
The first step in the Creation of Test Case is Creation of Test Scripts .

A test script consists of three principal parts-

• Its attributes

• The script commands
• The parameters

We will be creating a Test Scripts for Sales Order Scenario .

Step1 : Goto Transaction SECATT :

Now the Recording for the Transaction VA01 will start .We will Record and
save the Transaction .

After Recording is saved TCD Command Appears in the Command Editor.

Now Define Parameters . Only those parameters should be defined which are
expected to take values at runtime.

On clicking the Toggle Option : The Command Editor Appears .

On clicking the “Command Interface” Option the interface appears in left
bottom corner of the screen .
For each screen traversed screen name and screen number appears . Within
each screen all the Input values that were entered during Recording are
parameterized .

When all the screen input fields are parameterized , save the Script .

This Creates the Test Script for the Sales Order Scenario.

In the next Weblogs I will be discussing Test Data Containers , System Data
Containers and Test Configurations to complete the Test Case for the Sales
Order Scenario.


eCATT: Creation of Test Data Container
Creating Test Cases using eCATT

Creation of Test Data Container .

In my last weblog we were discussing creation of Test Case for Sales Order Scenario .
The first step for Creation of Test Case i.e. creation of Test script was covered in the
previous weblog . In this weblog we will continue the flow and cover Creation of “
Test Data Container” and “System data Container “ for the Test Scenario .

Transaction ‘SECATT’. : Creating Test Data Container

Now Create Variants for the Test Case .

The Script will be Tested with these 3 variants . These Variants define the different set
of values with which the Scenario will be tested . In the above case the Sales Order
Creation will be tested for different set of Sales Area Data ( different distribution
channels in namely: 10 12 & 16 )

After creation of Test Data Container , In the test script the parameters are assigned to
the Input values/Output Values .

Parameterizing Input Fields :
You must set the field mode to ‘S’, and enter a literal or the name of a parameter in the
VALIN column. At runtime, the screen field will be filled with the value that you
specified.

Parameterizing Output Fields :
You must set the field mode to ‘G’, and enter the name of a parameter in the VALIN
column. At runtime, the parameter will be filled with the value from the screen field.

Now Creation of System data Container :

Transaction ‘SECATT’.

Since we are not Doing Remote Testing .Therefore Test System is “NONE”
(In Case of Remote Testing RFC destination has to be created in SM59 and should be
specified under “RFC Destination Tab”)

In the next weblog Creation of “Test Configuration” and Execution of the Test Case
will be covered thus completing the Test Case for Sales Order Scenario.

eCATT: Creating & Executing Test Configurations

Creation of Test Configuration

In my previous weblogs on eCATT we were discussing “Creation of Test Case
for the Sales Order Scenario” . In the last weblog I had demonstrated the
creation of “Test Data Container” . The only step left for the completion of Test
Case for the above said scenario is the creation of “Test Configuration “.

I will explain creation of “Test Configuration” with the help of Screen Shots .

Transaction ‘SECATT’ . : Creating Test Configuration .

In the Test Configuration ( zsales_config ) Test data “ZSALES_DATA”(
Created in last Weblog ) is attached .

Note : The field Target System is Blank as Testing will be performed
Locally .

Now we have to copy variants from Test Data Container to the Test
Configuration .

The above screen shows the three variants namely :
· ECATTDEFAULT
· VAR1
· VAR3

Now the execution of this Test Configuration will Test the Sales Order Process
with three different set of data .

Executing Variants at once is very much possible in eCATT. Make sure that the
check box of Close RFC Connection is not selected otherwise for each variant
you will be prompted for login screen of target R/3 system.

There are following three ways of doing it -
1. Give nothing in Variant field of Start Options window at run time. This blank

value will execute all the variants including the eCATTDEFAULT variant.

2. Give * in the Variant field of Start Options window at run time. This will
execute all the variants except the ECATTDEFAULT one.

3. Give the specific one variant, which you want to execute in variant field of
Start Options window. This will execute only the specified variant.

Executing Test Configuration : zsales _config .

Now , The Log Generated after ZSALES_CONFIG was executed .

The Log reveals that variant ECATTDEFAULT AND VAR1 executed
successfully ( i.e sales order creation was possible with these set of Data )
But with Variant VAR3 Error : Order type OR not defined in Sales Area<1000

16 00 occurs .
From the above Test Scenario we were able to infer that
Standard Sales Order type OR cannot be created in Distribution channel 16 .

Thus we have successfully created a Test Case for the Sales Order Scenario .

In my next weblog on eCATT , I will discuss Creation of Test Case for
“WebDynpro” applications .

eCATT Tutorial


eCATT: Creating a Test Case for a Web Dynpro Application
This Weblog will discuss how to create a Test Case for a Web DynPro
Application. This is one of the major features of eCATT that allows users to
test business processes that cross system boundaries.

In my previous Welogs on eCATT , I discussed topics starting from
"Introduction to eCATT" to "Executing a Test Case using eCATT ". This
Weblog will go a step further and discuss how to create a Test Case for a Web
DynPro Application. This is one of the major features of eCATT that allows
users to test business processes that cross system boundaries.

The scenario for Test is as follows :

Scenario

The goal is to create a Test Case for a Web Dynpro Application that is on java
Stack . The application is for Purchase Order Creation.
The application will be tested for different set of data .
The url is : http://<server>:<port>/webdynpro/dispatcher/local/PO/CreatePO

Procedure:

The first step towards creating a Test Case for a Web Dynpro Application is to
create a
RFC destination in SAP .

Tcode : SM59
RFC Destination : WEBDYNPRO2 , Type : G
Target Host : <server>
Service : <port>

Now , create a System data Container assigning HTTP RFC destination created
above .

Tcode : SECATT

After creation of Test Data Container , Create Test Script . ( the creation of the
same has been discussed at length in my previous weblogs )

In pattern option under UI control Group select WEBDYNPRO command .
Entering System data Container and Target System .

The Application in our case is “/webdynpro/dispatcher/local/PO/CreatePO”

Recording starts . The application starts in the browser .

Entering appropriate Header Info in the fields .

Adding item details .

Creating Purchase Order .

The PO is created in SAP and the PO number is reflected in top right corner .

Now , click “Stop Recording” Option .

Below we can see a WEBDYNPRO command is created for each page of
application.

Now Parameterize the Input values

Creating Test Data Container .

2 Variants for are created . The Company code data is different in both cases .

For Test Variant 1 : Company Code is 1000.
For Test Variant 2 : Company Code is 3000.

Now Creating Test Configuration and attaching Test Data Container .

Executing Test Configuration .

Examining Log we see that :

PO can be created with var1 ( Company Code :1000 )

PO cannot be created with var2 ( Company Code :3000 )

Thus we were able to successfully Create a Test Case for a "Web Dynpro
Application" deployed on Java Stack using eCATT.
