As you all are well aware of this, Testing can be categorized in two ways: automated and manual. Many people find it difficult to choose which one to go for and thus here is a brief difference between the two.

Before moving further we would like to introduce to you one of the best It companies in India Ozonesoft Solutions.
What is Automated Testing?

When the codes/test scripts are written to automate test execution by the testers it is termed as Automated Testing. To develop the test scripts and validate the software testers use appropriate automation tools.

In case of automated testing the actual results are compared with the expected results thus Automated testing entirely relies on the pre-scripted test which runs automatically.

In Automated testing the interference of manual testers is not required thus Automated testing allows you to execute repetitive tasks and regression tests. Automated testing doesn't mean you can go fully automated, some manual effort to create initial testing scripts is also required in automated testing.

Still Automated testing allows you to execute repetitive ...
... tasks and regression tests without the intervention of manual testers.
What is Manual Testing?

When the tests are executed manually by a QA Analyst it is termed as manual testing. to discover bugs in software under development this type of testing is performed. In this type of testing the tester checks all the essential features of the given application or software. Here the automated testing tools are not used hence the tester checks all the essential features of the given application or software.

Ozonesoft Solutions has a team of expert testers who possess years of experience in web and application testing. Contact us for more details.

This helps in finding bugs in software systems. It is generally conducted by an experienced tester to accomplish the software testing process.

How Manual Testing Works?

This one which is very hands-on is manual testing. In this testing from test case creation to actual test execution analysts and QA engineers are required to be highly involved in everything.
How Automated Testing Works?

Automation testing involves testers writing test scripts that automate test execution. (A test script is a set of instructions to be performed on target platforms to validate a feature or expected outcome.)
Key Difference Between Automated and Manual Testing

Reliable & Accuracy:

Manual testing is done with human efforts and thus there are definitely chances of errors hence Manual testing is not accurate at all times.

Since automated testing is done with the help of scripts and codes hence it is more accurate, hence the chances of error is decreased.

Time:

Due to human involvement in testing and increased human efforts manual testing is time consuming and time taking.

If we talk about automated testing it is done with the help of software tools and hence it is comparatively less time consuming as the manual approach.

Resource:

In case of manual testing the resource required is human and human training.

In case of automated testing the resources are software tools.

Reused:

In case of automated testing the script once used can be reused across multiple releases. Automated testing is a practical option when the test cases are run repeatedly over a long time period.

In case of manual testing it could be possible when the test case only needs to run once or twice. Hence it is only possible when the test cases are run once or twice, and frequent repetition is not required.

Batch Execution:

In case of automated testing there is an increased benefit of Batch execution and hence in automated testing all the written scripts can be executed parallelly or simultaneously.

Whereas in manual testing this feature is not present hence batch execution is not possible in manual testing.

Performance Testing:

This type of testing is only possible in case of automated testing. With the help of load and stress testing To test the performance of the application automation test engineer needs to perform Performance Testing.

Programming Knowledge:

In manual testing the tester has no need to understand the programming language and thus testing can be done without it.

Whereas in the case of automated testing Without having an understanding of the programming language, we cannot write the test script.

Scenarios in which you must use automated testing:

For Time Consuming Tasks
For Repetitive Tasks
For Functional Testing
Performance or Load Testing
Advanced GUI Testing

Scenarios in which you must use manual testing:

During the Initial Development Stage
For Small or Short-Term Projects
During ad-hoc testing
Testing visual aspect of the UI
For Physical Products

As you got a brief on when to opt for manual and when for automated testing. Testing is an essential stage for every project and thus we at Ozonesoft Solutions concentrate highly on testing and have expert testers.
