Q1: What is functional testing ?
Functional testin refers to the use of the functional specification given by the client to verify the system against these requirements to ensure that it is ready for release. Essentially, functional tests define the working system in a useful manner by analyzing the individual components within the context of the application as a whole.
Q2: What are the different types of functional testing ?
The different types of functional testing include:
- Unit testing
- Component testing
- System testing
- Smoke testing
- Regression testing
- Integration testing
- User acceptance testing
- Sanity testing
Q3: How do functional and non-functional testing differ ?
Functional requirements refer to the “what” part while nonfunctional requirements encompass the “how” aspect of testing. Simply speaking, testing of functional requirements is done to verify that the application is executing the actions in the way it should, while nonfunctional testing is meant to verify whether that user expectations are being met.
Q4: What is the purpose of functional testing ?
Functional testing is a testing process which is used within software development cycle. It involves the testing of the software to ensure that it conforms with the specified set of requirements and expectations.
Q5: What is functional test plan ?
A functional test plan defines how the functional testing of an application will be completed to ensure that the input yields the expected outputs. This plan is just one component of the complete testing strategy. Ideally, functional test planning should start at the initial stage of application development, during the application design phase.
