By testing this component in isolation, the tester can ensure that the geolocation service works correctly and displays an accurate list of nearby locations. In this functional testing example, the middle component - the one under test - finds the user’s location via GPS and displays local banking centers from which they can choose. SEQUENTIAL TESTING QUALITY ASSURANCE DRIVERThe stub provides a simulated user profile, and the driver provides a simulated schedule of available appointment times. SEQUENTIAL TESTING QUALITY ASSURANCE SOFTWAREIf other software components rely on the component under test, the QA professional might use a stub and driver to simulate interactions between those dependent components.Ĭomponent testing example: A banking mobile app includes an option to schedule an appointment with a banking professional. The difference between unit testing and component testing is that the former is done by developers in a white-box format to verify that program modules execute, while the latter is done by testers in a black-box format to validate individual objects or parts of the software. Similar to unit testing, component testing assesses a part of the software in isolation from the broader system. Also called module testing, component testing checks individual parts of an application. Separate unit tests would validate other calculator functionality, such as subtraction, multiplication and division.Ĭomponent testing. A unit test would check whether the user can input two numbers and receive an accurate sum. Unit testing example: A developer builds a calculator app. Developers often execute unit tests through test automation. SEQUENTIAL TESTING QUALITY ASSURANCE CODEWhen done right, unit testing drives higher quality application code and speeds up the development process. This testing type provides the foundation for more complex integrated software. Unit testing validates the function of a unit, ensuring that the inputs (one to a few) result in the lone desired output. Before you can test an entire software program, make sure the individual parts work properly on their own. Let’s explore these types of functional tests with examples: Consider the advantages and disadvantages of each type of functional test, as well as the time and resources available to commit to QA. The following functional testing types, therefore, are neither intended to be used sequentially nor for every application. Your choice between these functional testing types - or how the scale of people involved in each stage - might depend on the stability of the app, the scope of the changes, or timelines set by the business. Another example: alpha, beta and production testing all describe builds that are in a production environment. Similarly, if an organization performs system testing, it might not perform acceptance testing, as that work might be considered redundant. While the objective sounds simple, the task involves many functional testing types, some of which might be preferred or prioritized over others depending on the nature of the application and organization.įor example, functional testing types like component, integration and system testing validate the ability to work in isolation or with other components, so the testing strategy might depend on how interoperable the app must be. The ultimate goal of functional testing is to ensure that software works according to specifications and in line with user expectations. These testing programs incorporate various functional tests to achieve exceptional results.įirst, we’ll discuss how various types of functional tests come together in an overall strategy, then we’ll dig into each one. Applause specializes in digital testing programs geared toward a particular platform or purpose. ![]() Organizations looking to boost quality can also deploy some specialized testing techniques that include a mix of different non-functional and functional testing types designed around a particular kind of platform.
