A test plan states what the items to be tested are, at what level they will be tested, what sequence they are to be tested in, how the test strategy will be applied to the testing of each item, and describes the test environment.
A test plan should ideally be organization wide, being applicable to all of organizations software developments.
The objective of each test plan is to provide a plan for verification, by testing the software, the software produced fulfils the functional or design statements of the appropriate software specification. In the case of acceptance testing and system testing, this generally means the Functional Specification.
The first consideration when preparing the Test Plan is who the intended audience is – i.e. the audience for a Unit Test Plan would be different, and thus the content would have to be adjusted accordingly.
You should begin the test plan as soon as possible. Generally it is desirable to begin the master test plan as the same time the Requirements documents and the Project Plan are being developed. Test planning can (and should) have an impact on the Project Plan. Even though plans that are written early will have to be changed during the course of the development and testing, but that is important, because it records the progress of the testing and helps planners become more proficient
Based on the above information, we can say that a test plan document can have all or few of the following contents based on the requirements:
Title
Identification of software including version/release numbers
Revision history of document including authors, dates, approvals
Table of Contents
Purpose of document, intended audience
Objective of testing effort
Software product overview
Relevant related document list, such as requirements, design documents, other test plans, etc.
Relevant standards or legal requirements
Traceability requirements
Relevant naming conventions and identifier conventions
Overall software project organization and personnel/contact-info/responsibilties
Test organization and personnel/contact-info/responsibilities
Assumptions and dependencies
Project risk analysis
Testing priorities and focus
Scope and limitations of testing
Test outline - a decomposition of the test approach by test type, feature, functionality, process, system, module, etc. as applicable
Outline of data input equivalence classes, boundary value analysis, error classes
Test environment - hardware, operating systems, other required software, data configurations, interfaces to other systems
Test environment validity analysis - differences between the test and production systems and their impact on test validity.
Test environment setup and configuration issues
Software migration processes
Software CM processes
Test data setup requirements
Database setup requirements
Outline of system-logging/error-logging/other capabilities, and tools such as screen capture software, that will be used to help describe and report bugs
Discussion of any specialized software or hardware tools that will be used by testers to help track the cause or source of bugs
Test automation - justification and overview
Test tools to be used, including versions, patches, etc.
Test script/test code maintenance processes and version control
Problem tracking and resolution - tools and processes
Project test metrics to be used
Reporting requirements and testing deliverables
Software entrance and exit criteria
Initial sanity testing period and criteria
Test suspension and restart criteria
Personnel allocation
Personnel pre-training needs
Test site/location
Outside test organizations to be utilized and their purpose, responsibilties, deliverables, contact persons, and coordination issues
Relevant proprietary, classified, security, and licensing issues.
Open issues
Appendix - glossary, acronyms, etc.
