Automation Testing Roadmap: A Complete Guide to Automation Testing [2024]

Test automation has become a vital aspect of the Software Development Life Cycle (SDLC), aimed at reducing the need for manual effort in routine and repetitive tasks. Although manual testing is crucial for ensuring the quality of a software product, test automation plays a significant role as well.

By effectively implementing test automation, software testers can focus on exploratory and functional testing, ultimately improving the overall quality of the software. For those interested in pursuing a career as a test automation engineer, let’s explore a roadmap to success.

What is Automation Testing?

Automation testing is a software testing technique that uses specialized tools and scripts to automate the execution of predetermined test cases and verify the behavior and performance of software applications. The goal of automation testing is to increase efficiency, reduce testing time, and enhance the overall quality of the software. Automation testing simulates a set of scripts or test scenarios and compares the actual outputs with the expected outputs, preparing a detailed report.

It is particularly useful in repetitive and time-consuming tasks which allow for faster and more frequent testing in the context of continuous integration, and continuous development (CI/CD) pipelines. It is specifically used in regression testing to compare whether the new code disrupts the functionality. It is important to understand that we cannot automate the whole process of testing. Wherever human intuition is required, such as exploratory testing or functional testing, manual testing will be used. A balanced approach combining both manual and automated testing can be used to ensure the quality of the software.

Manual Testing vs Automation Testing: Overview

Manual Testing relies on a human tester to execute test cases; therefore, it is suitable for exploratory or usability testing. Manual testing is cost-effective for smaller projects and initial testing phases. In automation testing, we use tools and scripts that can perform repetitive tasks efficiently. Automation testing is generally used in large-scale projects; it is crucial in regression testing or load testing. It is integrated into continuous integration pipelines for quicker feedback during the development stages. Choosing manual or testing depends on the nature of the project, cost considerations, and how much testing coverage is desired. Often, a mixture of both manual testing and automation testing is used, which leads to better software testing.

Parameters	Manual Testing	Automation Testing
Definition	Manual testers manually execute test cases without any automation tool or script. They execute predetermined test cases step-by-step to find defects.	Automation testers use automation tools or scripts to execute test cases. They compare the actual output with the desired output to find defects.
Processing time	Manual testing is time consuming.	Automation testing is faster than manual testing.
Resources required	Manual testing takes up human resources.	Automation testing takes up automation tools and trained employees.
Exploratory Testing	Exploratory testing is possible in manual testing, allowing to adapt testing based on observation and intuition.	Exploratory testing is not possible in automation testing.
Performance testing	Performance testing is not possible with manual testing.	Performance testing like load testing, stress testing, spike testing, etc is possible in automation testing.
Framework requirement	Manual testing does not involve the use of any automation frameworks or scripts.	Automation testing involves the use of automation frameworks to execute test cases.
Reliability	Manual testing is less reliable due to likelihood of human errors.	Automated testing is more reliable due to the use of automated tools and scripts.
Investment	Manual testing relies on humans therefore lower initial costs but can be time consuming and costly for large projects.	Automation testing demands higher initial investment but offers speed and efficiency for large projects.
