5.2. Specification Items

5.2.1. Specification Item Hierarchy

The specification item types have the following hierarchy:

5.2.2. Specification Item Types

5.2.2.1. Root Item Type

The technical specification of RTEMS will contain for example requirements, specializations of requirements, interface specifications, test suites, test cases, and requirement validations. These things will be called specification items or just items if it is clear from the context.

The specification items are stored in files in YAML format with a defined set of key-value pairs called attributes. Each attribute key name shall be a Name. In particular, key names which begin with an underscore (_) are reserved for internal use in tools.

This is the root specification item type. All explicit attributes shall be specified. The explicit attributes for this type are:

SPDX-License-Identifier

The attribute value shall be a SPDX License Identifier. It shall be the license of the item.

links

The attribute value shall be a list. Each list element shall be a Link.

type

The attribute value shall be a Name. It shall be the item type. The selection of types and the level of detail depends on a particular standard and product model. We need enough flexibility to be in line with ECSS-E-ST-10-06 and possible future applications of other standards. The item type may be refined further with additional type-specific subtypes.

The attribute value shall be an optional string. It shall be the description of the specified string attribute.

This type is used by the following types:

5.2.3.125. Test Case Action

This set of attributes specifies a test case action. All explicit attributes shall be specified. The explicit attributes for this type are:

action-brief

The attribute value shall be an optional string. It shall be the test case action brief description.

action-code

The attribute value shall be a string. It shall be the test case action code.

checks

The attribute value shall be a list. Each list element shall be a Test Case Check.

links

The attribute value shall be a list. Each list element shall be a Link. The links should use the Requirement Validation Link Role for validation tests and the Unit Test Link Role for unit tests.

This type is used by the following types:

5.2.3.126. Test Case Check

This set of attributes specifies a test case check. All explicit attributes shall be specified. The explicit attributes for this type are:

brief

The attribute value shall be an optional string. It shall be the test case check brief description.

code

The attribute value shall be a string. It shall be the test case check code.

links

The attribute value shall be a list. Each list element shall be a Link. The links should use the Requirement Validation Link Role for validation tests and the Unit Test Link Role for unit tests.

This type is used by the following types:

5.2.3.127. Test Context Member

A value of this type shall be of one of the following variants:

  • The value may be a set of attributes. This set of attributes defines an action requirement test context member. All explicit attributes shall be specified. The explicit attributes for this type are:

    brief

    The attribute value shall be an optional string. It shall be the test context member brief description.

    description

    The attribute value shall be an optional string. It shall be the test context member description.

    member

    The attribute value shall be a string. It shall be the test context member definition. It shall be a valid C structure member definition without a trailing ;.

  • There may be no value (null).

This type is used by the following types:

5.2.3.128. Test Header

A value of this type shall be of one of the following variants:

  • The value may be a set of attributes. This set of attributes specifies a test header. In case a test header is specified, then instead of a test case a test run function will be generated. The test run function will be declared in the test header target file and defined in the test source target file. The test run function can be used to compose test cases. The test header file is not automatically included in the test source file. It should be added to the includes or local includes of the test. All explicit attributes shall be specified. The explicit attributes for this type are:

    code

    The attribute value shall be an optional string. If the value is present, then it shall be the test header code. The header code is placed at file scope after the general test declarations and before the test run function declaration.

    freestanding

    The attribute value shall be a boolean. The value shall be true, if the test case is freestanding, otherwise false. Freestanding test cases are not statically registered. Instead the generated test runner uses T_case_begin() and T_case_end().

    includes

    The attribute value shall be a list of strings. It shall be a list of header files included by the header file via #include <...>.

    local-includes

    The attribute value shall be a list of strings. It shall be a list of header files included by the header file via #include "...".

    run-params

    The attribute value shall be a list. Each list element shall be a Test Run Parameter.

    target

    The attribute value shall be a string. It shall be the path to the generated test header file.

  • There may be no value (null).

This type is used by the following types:

5.2.3.129. Test Run Parameter

This set of attributes specifies a parameter for the test run function. In case this parameter is used in an Action Requirement Item Type item, then the parameter is also added as a member to the test context, see Test Context Member. All explicit attributes shall be specified. The explicit attributes for this type are:

description

The attribute value shall be a string. It shall be the description of the parameter.

dir

The attribute value shall be an Interface Parameter Direction.

name

The attribute value shall be a string. It shall be the parameter name.

specifier

The attribute value shall be a string. It shall be the complete function parameter specifier. Use ${.:name} for the parameter name, for example "int ${.:name}".

This type is used by the following types:

5.2.3.130. Test Support Method

A value of this type shall be of one of the following variants:

  • The value may be a set of attributes. This set of attributes defines an action requirement test support method. All explicit attributes shall be specified. The explicit attributes for this type are:

    brief

    The attribute value shall be an optional string. It shall be the test support method brief description.

    code

    The attribute value shall be a string. It shall be the test support method code. The code may use a local variable ctx which points to the test context, see Test Context Member.

    description

    The attribute value shall be an optional string. It shall be the test support method description.

  • There may be no value (null).

This type is used by the following types:
