Software testing is one of the most crucial stages in any software development lifecycle. It is done to make sure that your software performs according to the required requirements. So, in this article, we will be discussing about manual testing as well as automated testing.
Today we’ll be comparing and contrasting manual testing with automated testing based on criterias like testing time, accuracy, reliability, and more.
So, coming to the first item on the agenda is automated testing.
What is automation testing?
Testers use appropriate automation tools to develop the test scripts and validate the software. The goal is to complete test execution in less amount of time.
Automated testing involves testers who write code/test scripts to automate test execution.
What is manual testing?
Manual Testing is the procedure that involves testing software manually by Quality Analysts. It is one of the classical methods used to find and remove bugs in software that is still under development.
Automated Testing vs. Manual Testing
Automated Testing involves making use of various automation tools to execute use cases for this purpose.
Manual testing involves test cases that are executed by a human tester on a piece of software.
2. Processing Time
Automated testing is significantly faster when directly compared to manual testing.
Manual testing consumes human resources and is time-consuming in general.
3. Exploratory Testing
Automated testing does not allow for exploratory testing or random testing in general.
Manual testing does allow for exploratory testing and random testing methodologies to be implemented.
4. Initial Investment
Automation Testing involves spending a bigger amount upfront, but it pays off well because the ROI is better in the long term.
Manual testing involves spending a significantly smaller amount upfront, but , ROI is comparatively low.
Automated testing is very robust and reliable as the task is carried out by various tools and scripts.
Manual testing does not have a high rate of accuracy because it involves human error.
6. UI Changes
Automation testing has a small disadvantage because scripts need to be changed completely if there is a UI change.
Manual Testing can work fine with changes comparatively simple and quicker when compared
Automation testing calls for testing tools and automation engineers.
Manual testing calls for investing in human resources.
8. Value for money
Automation testing will work out if the test content volume is large enough.
Manual testing will not be cost-effective for high volume testing.
9. Performance Testing
Automated testing allows tests like load testing, stress testing, etc. which can be done very easily.
Manual testing does not offer feasibility when performance testing is a main point of concern.
10. Programming Knowledge
Automated testing involves a lot of programming; hence, it is a must.
Manual testing does not call for any requirement for programming knowledge.
11. Use In DevOps
Automated testing helps in build verification and testing, which are integral to the DevOps life cycle.
Manual testing defeats the automated build principle of DevOps entirely and lowers efficiency.
12. Ideal Use Case
Automation testing is very well suited for regression testing, load testing, highly repeatable functional test cases and more.
Manual testing is suitable for ad hoc testing, exploratory testing, and cases where there are frequent changes.
Automated testing brings about efficiency numbers to the table unlike any other
Manual testing is one of those legacy systems that are still needed across a spectrum of cases.
