Test Automation

Automation is now a part of advanced technology. If you want to learn about the Automation in testing so, this is the right place for you. I have collected this information from some valid resources & as per my own experiences and tried to put it here in an organized manner for you.  



What we will learn here 

  • Explain the differences between Manual and Automated Testing
  • Describe the key benefits of test automation
  • Understand what and when it is best to automate
  • Describe some best practices/tips for automation
  • Explain what is meant by an automation framework, types, features and metrics
  • Describe the Automation Maturity Model integration (AMI) and its key features
  • Review the ACOE Charter and Engagement Model
  • Learn where to find more information 



Before We Begin 



Change is a process, not an event. It requires Days, Weeks & Months hard work to change anything. 



MANUAL VS AUTOMATION 


Manual testing is time consuming, low reliability & inconsistent whereas Automated testing is having speed, repeatability, programming capability, more coverage & reusability. 

Manual Testing is best suited to the following areas/scenarios : 

Exploratory Testing : This type of testing requires the tester's knowledge, experience, analytical/logical skills, creativity, and intuition. The test is characterized here by poorly written specification documentation, and/or a short time for execution. We need the human skills to execute the testing process in this scenario. 

Usability Testing : This is an area in which you need to measure how user - friendly, efficient, or convenient the software or product is for the end users. Here, human observation is the most important factor, so a manual approach is preferable. 

Ad-hoc Testing : In this scenario, there is no specific approach. It is a totally unplanned method of testing where the understanding and insight of the tester is the only important factor. 


What is Automated Testing ?

Test Automation Software increase the effectiveness, efficiency & coverage.

Regression Testing : Here, automated testing is suitable because of frequent code changes and the ability to run the regressions in a timely manner. 

Repeated Execution : Testing which requires the repeated execution of a task is best automated. 

Load Testing : Automated testing is also the best way to complete the testing efficiently when it comes to load testing. 

Performance Testing : Similarly, testing which requires the simulation of thousands of concurrent users requires automation. 

Manual Testing 

  • Not accurate at all times due to human error 
  • Time - consuming 
  • Investment for human resources 
  • Only practical when the test cases are run once or twice where repetition is not required
  • Allows for human observation, which may be more useful if the goal is user - friendliness or improved customer experience

Automated Testing 

  • More reliable as it's performed by tools and/or scripts
  • Executed by software tools, so it's significantly faster than a manual approach
  • Investment for testing tools
  • Practical option when the test cases are run repeatedly over a long time period
  • Does not entail human observation and cannot guarantee user-friendliness or positive customer experience.

The Benefits of Test Automation 

Explicit Benefits ( ROI )

Additional cost for automation vs the benefit gained by an unattended version 

Implicit Benefits 
  • Repeatability 
  •  Accuracy 
  • Coverage 
  • Frees testers to other tasks 
  • Increased motivation ( but can also be a threat )
  • Reliability
  • Improvement of development process

A Journey to the Malana Village

A Journey to the Malana Village . . . . . . . .  “Travel makes one modest. You see what a tiny place you occupy in the world.”  It's true that traveling makes you more aware of the places which exist in this world. Doesn't you want to watch those places before you die?  Take an off from your busy schedule and give this life a beautiful chapter, before the book ends.  Every journey is precious and memorable. We took many pictures to record that moment, feelings were extremely high!  I had recently visited that peaceful place "MALANA". If you had visited malana before you realized a special bond for that place. A bond which can't squeeze out from the inner soul.  The song which is playing in the background of this video is a Nepali Song "Chiso Chiso Hawa Sarara" By Muna Thapa Magar. I didn't understand the meaning actually but that time it making sense by just looking outside of the window. All the memorable moments just coming in the thoughts...
