Common types of Test Strategies

 1.Analytical-

This type of test strategy is based on an analysis of some factor (For example-requirement or risk). Risk-based testing is an example of an analytical approach, where tests are designed and prioritized based on the level of risk.

2.Model-Based-

 In this type of test strategy, tests are designed based on some model of some required aspect of the product, such as a function, a business process, an internal structure, or a non-functional characteristic (for example- reliability).

3.Methodical-

This type of test strategy relies on making systematic use of some predefined set of tests or test conditions, such as a taxonomy of common or likely types of failures.

4.Process-compliant -

This type of test strategy involves analyzing, designing, and implementing tests based on external rules and standards, such as those specified by industry-specific standards

5.Directed -

 This type of test strategy is driven primarily by the advice, guidance, or instructions of stakeholders, business domain experts, or technology experts, who may be outside the test team or outside the organization itself.

 6.Regression-averse-

 This type of test strategy is motivated by a desire to avoid regression of existing capabilities. This test strategy includes reuse of existing testware, extensive automation of regression tests, and standard test suites. 

7.Reactive-

In this type of test strategy, testing is reactive to the component or system being tested, and the events occurring during test execution, rather than being pre-planned (as the preceding strategies are).
