Test Strategy

Hi Megha,

The test levels to be performed in testing and the description of testing activities within those test levels is known as test strategy.

There are many types of test strategy and selection of appropriate test strategy is the major factor behind testing success.

Test strategy also comes in test deliverables, the test strategy which is followed for testing should be informed to the project stakeholders.

Following are the major types of test strategies that are followed in software testing:

Analytical
Risk based test strategy
Requirements based test strategy
Model based
Methodical
Process compliant
Dynamic
Consultative or Directed
Regression averse


The test strategy is a formal description of how a software product will be tested. A test strategy is developed for all levels of testing, as required. The test team analyzes the requirements, writes the test strategy and reviews the plan with the project team. The test plan may include test cases, conditions, the test environment, a list of related tasks, pass/fail criteria and risk assessment.
Inputs for this process:
1. A description of the required hardware and software components, including test tools. This information comes from the test environment, including test tool data.
2. A description of roles and responsibilities of the r resources required for the test and schedule constraints. This information comes from man-hours and schedules.
3. Testing methodology. This is based on known standards.
4. Functional and technical requirements of the application. This information comes from requirements, change request, technical and functional design documents.
5. Requirements that the system can not provide, e.g. system limitations, Outputs for this process:
6. An approved and signed off test strategy document, test plan, including test cases.
7. Testing issues requiring resolution. Usually this requires additional negotiation at the project management level.
