Types of BlackBox

Types Of Black Box Testing

Black box testing is a methodology of performing tests. These tests can be designed to accomplish a few different goals, including:

Functional Testing: Functional testing is intended to validate that an application does what it is supposed to do. For example, functional tests may test an application’s authentication mechanism to check that legitimate users can authenticate successfully while invalid login attempts are rejected. Common types of functional testing include sanity checks, integration testing, and system testing.

Non-Functional Testing: Non-functional testing evaluates how well an application performs its core functions. Examples of tests include performance, usability, scalability, and security testing.

Regression Testing: Regression testing is designed to ensure that a change to an application does not break functionality. For example, regression testing should be performed after patching a vulnerability in an application to ensure the patch has not caused the application to fail functional or non-functional tests.

What is Black Box Testing?

Black-box testing is a type of software testing in which the tester is not concerned with the internal knowledge or implementation details of the software but rather focuses on validating the functionality based on the provided specifications or requirements.

Advantages of Black Box Testing

The tester does not need to have more functional knowledge or programming skills to implement the Black Box Testing. It is efficient for implementing the tests in the larger system. Tests are executed from the user’s or client’s point of view. Test cases are easily reproducible. It is used to find the ambiguity and contradictions in the functional specifications.

Disadvantages of Black Box Testing

There is a possibility of repeating the same tests while implementing the testing process. Without clear functional specifications, test cases are difficult to implement. It is difficult to execute the test cases because of complex inputs at different stages of testing. Sometimes, the reason for the test failure cannot be detected. Some programs in the application are not tested. It does not reveal the errors in the control structure. Working with a large sample space of inputs can be exhaustive and consumes a lot of time.
