Test Script		 The step-by-step instructions that realize a test, enabling its execution. Test Scripts may take the form of either documented textual instructions that are executed manually or computer readable instructions that enable automated test execution.
UML Representation: There is no UML representation for this artifact.
Role: Tester 
Optionality/ Occurrence: Define as many Test Scripts as needed to provide the appropriate amount of testing.

Purpose To top of page

The purpose of the Test Script is to provide the implementation of a subset of required tests in an efficient and effective manner.

Brief Outline To top of page

Each Test Script should consider various aspects including the following:

  • The basic computer hardware requirements; for example, Processors, Memory Storage, Hard-disk Storage, Input/ Output Interface Devices
  • The basic underlying software environment; for example, Operating System and basic productivity tools such as e-mail or a calendar system
  • Additional specialized input/output peripheral hardware; for example, Bar-code scanners, receipt printers, cash draws, and sensor devices
  • The required software for the specialized input/ output peripheral hardware; for example, drivers, interface and gateway software
  • The minimal set of software tools necessary to facilitate test, evaluation and diagnostic activities; for example,  memory diagnostics, automated test execution, and so forth
  • The required configuration settings of both hardware and software options; for example, video-display resolution, resource allocation, environment variables, and so on
  • The required "preexisting" consumables; for example, populated data sets, receipt printer dockets, and the like.

Properties To top of page

There are no UML representations for these properties.

Property Name

Brief Description

Name An unique name used to identify this Test Script.
Description A short description of the contents of the Test Script, typically giving some high-level indication of complexity and scope.
Purpose An explanation of what this test script represents and why it is important.
Dependent Test and Evaluation Items Some form of traceability or dependency mapping to specific elements such as individual Requirements that need to be referenced.
Preconditions The starting state that must be achieved prior to the Test Script being executed.
Instructions Either the step-by-step instructions for executing the manual test, or the machine readable instructions that, when executed, stimulate the software in a similar manner to the actions that would be undertaken by the appropriate Actor, human or otherwise.
Observation Points One or more locations in the Test Script instructions where some aspect of the system state will be observed, and usually compared with an expected result.
Control Points One or more locations in the Test Script instructions where some condition or event in the system may occur and needs to be considered in regard to determining the next instruction to be followed.
Log Points One or more locations in the Test Script instructions where some aspect of the executing test script state is recorded for the purpose of future reference.
Postconditions The resulting state that the system must be left in after the Test Script has been executed.

Timing To top of page

The initial Test Scripts can be created as soon as there are some software components against which to implement the tests. The Test Scripts are modified and extended throughout the remainder of the lifecycle, during the course of each test cycle.

Responsibility To top of page

The Tester role is primarily responsible for this artifact. Those responsibilities include:

  • identifying and defining each Test Script, and managing all subsequent changes
  • ensuring the Test Script accurately reflects the required test, identified by one or more a Test Ideas or defined in one or more Test Cases
  • ensuring the Test Script is implemented according to defined standards to be compatible and maintainable with the other Test Scripts
  • ensuring the Test Script makes reasonably efficient use of the available resources
  • developing the Test Script with a focus on economy of effort and identifying opportunities for reuse and simplification
  • developing the Test Script so that it can be used as part of a Test Suite

Tailoring To top of page

Manual Test Scripts may be documented using some form of text document, spreadsheet, or table, or using a specialized test documentation support tool.

Automated Test Scripts may be created (recorded) or automatically generated using test automation tools, programmed using a programming language, or any combination of the above. The Test Scripts may be modified to include programming concepts, such as referencing common function libraries, using variables, loops, and branching to increase the efficiency, effectiveness, and resilience of the scripts.

In certain cases, it will be appropriate to use automated Test Scripts as informal, transient resources, avoiding the effort and cost of maintaining them.
