#SEQUENTIAL TESTING QUALITY ASSURANCE SOFTWARE#

Sometimes requirements are poorly designed form the beginning, and software development reminds wandering in the dark. The reasons for sudden changes in a project may be different. Besides, there are dynamic projects, where pre-approved requirements can lose their relevance and change – that’s especially true for Agile projects.

#SEQUENTIAL TESTING QUALITY ASSURANCE CODE#

IT specialists are well aware of how unpredictable code can be, even if it seems perfectly written. Integration testing is the examination of the smallest possible combinations of those parts. To wrap it up, unit testing is the examination of the smallest functional parts of code. As a rule, software engineers run unit testing at the earlier stages of product development.

If integration testing is the first chapter of the story (or the pilot of a TV show), unit testing is a prequel.

It prepares the functionality to the following stage which is integration testing. Unit testing is the initial stage of the QA process. The earlier we notice something abnormal, the lower will be the cost of a mistake. Therefore, any problems arising when we assemble several smaller parts into a subsystem can be associated with the particularities of the interaction between these units. The fact that units have successfully passed the tests at the previous stages doesn’t guarantee that they will work well together. Integration testing goes further: we look for errors that happen when units start interacting. Unit testing implies checking the smallest functioning parts of code separately. Integration testing and unit testing are two levels of software testing, where a unit is the basic one and integration is the sequential one. They don’t need to know how code works or consider the backend part of the components. This method implies that a testing team interacts with an app and its units via the user interface – by clicking on buttons and links, scrolling, swiping, etc. Integration testing is performed using the black box method. A QA team groups these units into sets and checks them in accordance with the test plan. If we check the ability to log in or sign up after a user adds items to their basket and wants to proceed to the checkout, we check the integration between these two functionalities.įor integration testing, the team uses components that have already been tested as separate units.

Integration testing is a type of testing meant to check the combinations of different units, their interactions, the way subsystems unite into one common system, and code compliance with the requirements. What these elements are and why is it so important to verify their integrity – all in today’s post. The name suggests that during integration testing we examine the integration of different elements. Integration testing is an essential step on the way to releasing an app with thought-out logic and flawless performance. If you develop software, you surely aim to create a well-thought-out app logic and workable features to support it.
