Automation Estimation

Automation Estimation and Analysis

Approach (2 types)
  • Functionality based (one to many)
  • Scripts (Test case) based(one to one)

Should attend (take) Knowledge Transfer session on the given task


Automation Process 2 Stages
First stage
a. Analyzing the scripts (Test cases)
b. Preparing analysis sheet
c. Estimating the time
d. Sending summary for Approval
e. Confirmation

Second stage

a. Preparing stricture
b. Preparing OR
c. Creating re-usable components and functions ect.
d. Creating scripts and Enhancing scripts
e. Dry run
f. Final Execution
g. Peer Execution
h. Delivery of scripts










Detailed study of stage one
Analyzing scripts: with out manual execution we can’t say whether scripts is automatable or not


  • It is a critical and important stage
  • Entire task lay on this stage

How many Scripts we can analyze in a day?

As an automation engineer we have to decide script complexity for automation.

How can we decide whether the script is high or medium or low?

In order to decide that we will see a single script for example

3 Types of Maintenances (Modifications)



1. Corrective maintenance (Fixes): involved correcting software failures, performances failures and implementation failures in order to keep the system working properly.


2. Adapting the system in response to changing data requirements or processing environments constitutes called as adaptive maintenance.


3. Perfective maintenance covers any enhancement to the system where the objective may be to provide additional functionality, increased processing efficiency or improved maintainability.
