What is Software Testing (Quality Control Context)

• The main goal of software testing in QC is to identify defects or issues in the finished software. Testing involves running the software through various scenarios to see if it behaves as expected and to catch any bugs or errors.

• Testing verifies that the software meets the quality standards and specifications defined during development. This includes checking if the software performs correctly, is user-friendly, and handles different conditions as intended.

Software Testing Attributes

Execution Based

• Software testing involves running the software and checking how it behaves. This means executing the software and interacting with it to see if it works as expected. It’s like using the software in real scenarios to test if it performs correctly.

Validation

• Testing is about validating that the software meets the requirements and does what it’s supposed to do. It’s like checking if the software delivers the right results and solves the problem it was designed to address. Validation ensures that the software is fit for its intended purpose.

Software Testing Types

There are different types of software testing, each focusing on various aspects of the software:

• Unit Testing: Tests individual components or functions to ensure they work correctly.

• Integration Testing: Checks if different parts of the software work together properly.

• System Testing: Evaluates the complete software system to ensure it functions as a whole.

• Acceptance Testing: Validates if the software meets the user’s needs and requirements.

Activities

Testing involves several activities to ensure quality:

• Creating Test Cases: Writing specific scenarios and conditions to test the software.

• Running Tests: Executing the test cases to see how the software performs.

• Recording Results: Documenting the outcomes of the tests, including any defects or issues found.

• Reporting Issues: Communicating any problems to the development team for fixing.
