Difference between Testing and Checking
In general, we can say that both Testing and Checking are used to evaluate a software product to make sure it behaves as expected. Both these processes are performed before the delivery of the product to ensure the delivery of correct and genuine product.
Read this article to learn more about Testing and Checking and how they are different from each other.
What is Testing?
Testing is defined as a process of validating a product along with learning about that product by investigating and exploring the product during the process. Thus, testing is the process that motivate the tester to find new information.
Testing of a product is performed, when we need to observe a product for evaluating it. The person who performs testing is called a "tester". In software product development, there are many types of testing such as unit testing, beta testing, integration testing, black box testing, white box testing, etc.
What is Checking?
Checking is defined as a process where one verifies a particular functionality which is expected to be present in the product. Checking is performed to verify that the product is working fine or not. Checking is generally performed for the feature verification of the product which is working fine before the code changes.
Checking provides information about the presence of errors, bugs and defects in the software product. The output of checking is either Yes or No. The person who performs the checking of the product is known as a "checker".
Now, on the basis of process of both there could be some important differences between both which are as follow.
Difference between Testing and Checking
The following are the important differences between Testing and Checking −
Key |
Testing |
Checking |
|---|---|---|
Definition |
Testing could be defined as a process of validate a product along with learning about that product by investigating and exploring the product during the process. |
Checking could be defined as the process where one verifies a particular functionality which is expected to be present in the product, is working fine or not. It is generally done for the feature verification of product which is working fine before the code changes. |
Covering area |
Testing mostly focus on the area of functionality which is newly developed according to the new requirement or enhancement in the product. |
Checking is primarily focused to ensure the expected working of existing functionality. |
Performers |
The person who performs testing is known as a Tester. |
The person who performs checking is known as a Checker. |
Outcome |
The outcome of testing generally represented as expected or not also outcome is compared with the predefined expected result. |
Outcome is represented as YES or NO, i.e., whether a particular functionality is working fine or not. |
Update |
In testing testers need not to update regarding what happens other area of the product or what are the new updates that recently take place. |
Checkers need to get updated as they need to check the functionality after update whether it is working fine after update too or not. |
Quality Assurance |
Testing of a product generally gives the quality assurance which helps the developers, project managers to decide about the project that how many defects or bugs their product currently have. |
Checking is a quality assurance practice which is done by programmers to help them check the quality assurance of the work done by them. |
Conclusion
The most significant difference that you should note here is that testing is the process of validating a product along with learning about the product by investigating and exploring the product during the process, whereas checking is the process where one verifies a particular functionality which is expected to be present in the product, is working fine or not.
