You can use a mock object to verify that you have called it in the way expected. In Mockito, mocked objects are automatically stubs, and verification occurs explicitly.
From Mockito's "Why do we need another mocking framework?":
Separation of stubbing and verification. Should let me code in line with intuition:
stub before execution, selectively verify interactions afterwards. I don’t
want any verification-related code before execution.
You can stub the behavior of calls before they're called. For example (from the Mockito home page):
when( mockedList.get(0)).thenReturn( "first" );
You can verify interactions with mocked objects after they're called. For example:
verify( mockedList ).add("one");

The automation backend architecture of Appium has undergone significant development along with the release of numerous new capabilities. With the advent of Appium, test engineers can cover mobile apps, desktop apps, Flutter apps, and more.
To understand the agile testing mindset, we first need to determine what makes a team “agile.” To me, an agile team continually focuses on becoming self-organized and cross-functional to be able to complete any challenge they may face during a project.
Software Risk Management (SRM) combines a set of tools, processes, and methods for managing risks in the software development lifecycle. In SRM, we want to make informed decisions about what can go wrong at various levels within a company (e.g., business, project, and software related).
Continuous integration is a coding philosophy and set of practices that encourage development teams to make small code changes and check them into a version control repository regularly. Most modern applications necessitate the development of code across multiple platforms and tools, so teams require a consistent mechanism for integrating and validating changes. Continuous integration creates an automated way for developers to build, package, and test their applications. A consistent integration process encourages developers to commit code changes more frequently, resulting in improved collaboration and code quality.
