Which model classifies test types/test levels based on test objectives and can be divided into four quadrants?

The correct answer is based on the concept of the Testing Quadrants, which serve as a framework for understanding different types of testing in terms of their objectives and the focus of the testing efforts. In this model, testing is categorized into four quadrants that help teams identify the purpose of each testing activity, facilitating a balanced approach to testing throughout the development lifecycle.

The four quadrants are as follows:

1. Quadrant 1: Technology-facing tests that support the team, such as unit tests and component tests. These are typically automated and focus on ensuring that the code meets technical requirements.

2. Quadrant 2: Business-facing tests that support the team, like functional testing and exploratory testing. This quadrant emphasizes validating user requirements and ensuring that the software aligns with business needs.

3. Quadrant 3: Technology-facing tests that critique the product, such as performance and security testing. These are focused on evaluating non-functional aspects, identifying weaknesses, and ensuring robustness.

4. Quadrant 4: Business-facing tests that critique the product, including user acceptance testing and alpha/beta testing. Here, the emphasis is on the end-user experience and validating that the product meets actual user needs.
