Test team in software testing company is clearly aware that app under test can be nominally divisible into three levels: Functional Tests Layer (Non-UI), Unit Tests Layer and GUI Tests Layer.
Automated testing service is necessary to provide you with an accelerated and collaborative approach towards functional testing by combining global terms and efficient tools to specify what needs to be automated, improve the effectiveness and speed the returns on existing investment in testing tools.
To maximally improve the product quality, you are recommended to use automated testing tools that can apply to the above-referred levels.
Automated software testing as a service is used to increase efficiency, effectiveness and coverage of functional software testing process and is crucially valuable when there is a demand for the involvement of continuous efforts in repeated testing to reduce pressures on budgets and enable you to reach desirable quality.
Test Automation Strategy Built Upon a Three-Level Model:
Functional Tests Level – unlikely, the GUI layer is not well-suitable for testing all business logic of the app. It could be a characteristic of implementation due to which business logic is hidden from the user. Then, by direct and immediate accessing functional layer you will be able to do testing of the app’s business logic without passing the user’s interface, but the only testing team can get the access with the permission of the developers.
Unit Test Layer – at this very level automated tests are just unit tests or the component created by developers. These tests can be also written by testers if they can do that. In the initial stages of the project, similar tests, and when they are always actualized and complemented with new tests, are capable of protecting the project from the majority of severe problems by checking the “defect fixes”.
GUI Test Layer – at this level, not only the user interface can be tested, but also the functionality through the performance of the operation that causes the app’s business logic. These are cross-cut tests having a bigger impact on than only testing of the functional layer that is to be performed through emulation of the end-user operations using a graphical interface.
Automated testing services are faster than manual processes; this type of testing is integrated around all the phases of software development test automation strategy.
