Test Automation Life Cycle - qainsights
1. Automation
Feasibility Analysis
Before kicking off implementing test
automation, it is mandatory to analyse the feasibility of the application under
test (AUT). Whether AUT is a right candidate or not for the test automation?
Also, feasibility analysis should be
done on the manual test case pack which enables automation engineers to design
the test scripts.
Apart from above feasibility, tool
check can be done if your client insists to use their recommended tool
selection.
Following are the feasibility check
to be done to begin test automation:
- AUT
automation feasibility
- Test
Case automation feasibility
- Tool
feasibility
2. Test
Strategy
Test Strategy is the most critical
phase in test automation. This phase defines how to approach and accomplish the
mission. First and foremost in test strategy is selection of test automation
framework.
Following are the types of test
automation framework:
1.
Record and Playback Framework
2.
Functional Decomposition Framework
3.
Keyword/Table Driven Framework
4.
Data Driven Framework
5.
Hybrid Framework
6.
Business Process Framework
Most of the projects prefer Hybrid
framework which is the combination of Keyword driven and Data driven framework.
Because it has high reusability, more robust and pros when compared with other
kinds of frameworks.
Other factors which involves in test
strategy as follows
1.
Schedule
2.
Number of resources
3.
defining SLA
4.
Mode of communication process
5.
Defining in-scope and out-of-scope
6.
Return on Investment analysis
3. Environment
Set up
It is ideal to execute test
automation scripts in regression environment. Test environment set up phase has
following tasks:
1.
Sufficient tool licenses
2.
Sufficient add-ins licenses
3.
Sufficient utilities like comparison
tools, advance text editors etc.
4.
Implementation of automation
framework
5.
AUT access and valid credentials
4. Test
Script Development
This phase is the inception of
implementing test automation. Activities of Automation test engineers as
follows:
1.
Object Identification
2.
Creating Function Libraries
3.
Building the scripts
4.
Unit testing the scripts
5.
Warm-up test execution
5. Test
Script Execution
Unit tested and signed-off Test
scripts will be delivered to automation testing team for script execution.
Following are the tasks involved with test script execution team.
1.
Test script execution
2.
Updating the execution or coverage
tracker
3.
Defect Logging
6. Test
Result Generation and Analysis
Result generation and analysis is the
last phase and important deliverable in test automation. Results must be base lined
and signed-off. Following are the important activities in this phase:
1.
Result analysis
2.
Report generation
3.
Documenting the issues and knowledge
gained
4.
Preparation of client presentation
