Black Box Testing Services in India

Black-box testing is a method of software testing that tests the functionality and user interface of an application without peering into its internal structures or workings is called Black Box testing. It is done by the Test Engineer once the developer completes the white box testing and hand over the application to Testing team. Test cases are built around specifications and requirements. It uses external descriptions of the product, including requirements, specifications, and designs to derive the test cases. These tests can be functional or non-functional.

Black box testing clearly divide user’s angle from the developer’s angle through visibly defined roles. Large numbers of fairly skilled testers can test the application with no ability of programming language or os. The tester is forgetful to the system architecture and does not have access to the source code. Typically, when performing B. Box testing, a tester will interact with the system’s user interface by providing inputs and examine the output without knowing how and where the inputs are worked upon.

Black Box testing consists Functional testing, Integration testing, System testing and User Acceptance testing.

Functional testing: Testing the individual or independent component of the application is called Functional Testing.

Integration testing: Testing the application by combining the modules together and checking for the data flow between them.

System testing: It is an end to end testing where testing environment is same as the production environment.

User Acceptance testing: Testing the application by the customer or worker of the client or domain experts of the clients to build the confidence in the system is called the User Acceptance testing.
