Agenda Takeaways

What is Product Migration

Different types of product architecture

Problem area

Automation process flow

Why ANT?

Framework Architecture

Sample scripts with examples

Test execution report

Schedule Automation Script

3

Takeaways To automate different complex tasks (Non GUI tasks)

To develop platform independent framework

Automate to maximum

(Manual tasks + GUI tasks)

4

What Is Product Migration?

Migration is the process of moving product from

Smaller machine to bigger

One platform to another

One application to another

One version to another

It is not just a copy, it is more than that

5

Single Machine Architecture

Grid Architecture

6

Multi Machine Architecture

7

Problem Area

8

Solution?

Develop a framework which automate different tasks

9

Automation Process Flow

10

Why ANT?

Ease of use

Platform independent

Is not only a build tool; it can do much more…

Can invoke third party plug-ins tasks

Can handle dependencies between targets

Custom tasks – Java, Groovy, etc.

ANT Script To Check OS

Run Executable

Check OS

<target name="checkBuild" depends="checkOS"><if><isset property="isWindows"/><then>

<exec executable="${build.location}\setup.exe" ><arg line="-quiet -responsefile ${responsefile}" />

</exec></then><else>

<exec executable="${build.location}/setup.sh" ><arg line="-quiet -responsefile ${responsefile}" />

</exec></else></if>

</target>

<target name="checkOS" ><condition property="isWindows">

<os family="windows"/></condition><condition property="isUnix">

<os family="unix"/></condition>

</target>

13

ANT Script With Java Integration<project name="testProject" default="checkBuild" >

<target name="checkBuild” ><echo message="Checking availability of build"/><getBuild/><echo message="Build to be tested = ${getBuild.name}"/>

</target>

<!-- Script to generate last weekly build name --> <scriptdef name="getBuild" language="beanshell">

<![CDATA[final String BUILD_INITIALS = “product.";final String DATE_FORMAT = "yyyyMMdd";final long DAY_MILLIS = 86400000;Calendar cal = new GregorianCalendar();int day = cal.getTime().getDay();if(day > 3) {

cal.setTimeInMillis(cal.getTimeInMillis() - ((day - 3) * DAY_MILLIS));} else if (day < 3) {

cal.setTimeInMillis(cal.getTimeInMillis() - ((4 + day) * DAY_MILLIS));}

java.text.DateFormat df = new java.text.SimpleDateFormat(DATE_FORMAT);project.setProperty("getBuild.name", BUILD_INITIALS + df.format(cal.getTime()));

]]></scriptdef>
