It has remained a question for long that which testing method to opt and when. Here is the end to that dilemma. See, how the clear differences point to one single name.
|MANUAL TESTING||AUTOMATION TESTING|
|Manual Testing is Exercising & Evaluating the software & software components to verify that it satisfies specified requirement or to identify the difference between Expected and actual results.||Automation is the use of tools or software so as to execute tests as needed and thereby detect errors. It is done based on algorithms and programs where the query is set and fired as many times as needed.|
|Whenever you need to test the Smoke and integration testing of any web or mobile application, manually you can do it with ease.||Automation can be used for analyzing the Performance of a system in terms of stress and load|
|Test the implication of some very short module quite less number of times.||When number of users interacting with the system is plausibly going to increase, automated testing can simulate it all.|
|Functionality testing of any web or mobile application.||Automation requires checking the test cases with record & run feature through the scripting|
|Only testing skills are needed||Knowledge of using automated tools plus testing skills both is required|
|Accurate except in cases of human error||Accuracy depends only on the accuracy of Tools|
Integration Testing: Testing a combination of different modules.
Ad-Hoc Testing: Purpose specific testing where method is not strategic.
Regression Testing: Checking system when one module affects another. This is done after solving bugs.
Performance Testing: For responsiveness, scalability.
In general, automated testing wouldn’t make sense for short-term projects because the upfront cost is too high. In addition, if you’re testing for things that require the human touch like usability, it’s better to have a ‘human’ tester.
Companies that have little expertise in the area are also recommended to begin with manual testing. Once the team has mastered testing risks and test coverage, they can then move toward automation considering the prior mentioned facts, go for the best choice.
