Functional testing is a vital part of the software development process, and knowing how to properly carry out these tests can save organizations time and money. When writing functional test cases, remember to focus on verifying functionality and not on finding bugs. Functional tests can be performed manually or automatically, but using automated tools can help identify defects early in the development process.
Keep in mind that functional testing is just one type of testing and should be used alongside other types of tests, such as unit testing or integration testing, to ensure comprehensive coverage. There are a few things you should know about functional testing before diving in.
Functional testing is a type of black-box testing that focuses on the functionality of an application or system. It is used to verify that the application or system under test behaves as expected. Functional testing can be performed manually or automatically.
When performing functional testing manually, testers will execute test cases and compare the actual results with the expected results. If the actual results match the expected results, then the test case passes. If they don’t match, then the test case fails.
- Just remember to keep the following things in mind: – Functional tests should focus on verifying functionality, not on finding bugs. – Functional tests can be performed manually or automatically. – Automated functional testing tools can save time and money by identifying defects early in the development process. – Functional testing is not a substitute for other types of testing.
- Functional vs Non-functional Testing Traditionally, functional testing goes before non-functional testing. But what’s the difference between these two? Functional testing focuses on product features while non-functional focuses on user expectations. The latter measures product behavior and characteristics such as reliability, accessibility, and performance. An example of a non-functional requirement is ensuring that any update to a database is visible to all users within three seconds. To make it clearer, let’s take a login function as an example.
