What is Software Testing? What is the role of a Software Tester? CompareBlack Box and White Box Testing.

Sure! I can answer your question step by step.

Step 1: What is Software Testing? Software Testing is a process of evaluating a software application or system to ensure that it meets the specified requirements and works as expected. It involves executing the software with the intention of finding defects or errors and verifying that it functions correctly.

Step 2: What is the role of a Software Tester? The role of a Software Tester is to identify and report defects or issues in the software application. They are responsible for designing and executing test cases, analyzing test results, and providing feedback to the development team. Testers also play a crucial role in ensuring the quality and reliability of the software.

Step 3: Compare Black Box and White Box Testing. Black Box Testing:

• Black Box Testing is a testing technique where the internal structure or implementation details of the software are not known to the tester.
• Testers focus on the inputs and outputs of the software without considering its internal workings.
• It is mainly used to validate the functionality and behavior of the software from a user's perspective.
• Test cases are designed based on the software's requirements and specifications.

White Box Testing:

• White Box Testing is a testing technique where the internal structure and implementation details of the software are known to the tester.
• Testers have access to the source code and can analyze the internal logic and structure of the software.
• It is mainly used to validate the internal workings of the software, such as code coverage, control flow, and data flow.
• Test cases are designed based on the internal structure and logic of the software.

In summary, both Black Box and White Box Testing are important techniques in software testing. Black Box Testing focuses on the functionality and behavior of the software, while White Box Testing focuses on the internal structure and logic. The choice of testing technique depends on the specific requirements and objectives of the testing process.
