BS 7925-2 PDF

This BS article has very limited content, and this standard has now been superseded by ISO/IEC/IEEE – so what little is here, is obsolete anyway . BS – 2. Standard for Software Component Testing. Working Draft Date: 28 April produced by the. British Computer Society Specialist Interest. This paper covers both the development of BS and compliance with the finished standard. The process used to produce BS is described by.

On the determination of an appropriate time for ending the 7295-2 testing process. Both valid and invalid values are partitioned in this way. Each partition shall contain a set or range of values, chosen such that bx the values can reasonably be expected to be treated by the component in the same way i. The model shall comprise bounded partitions of ordered input and output values. Syntax Testing uses a model of the formally-defined syntax of the inputs to a component.

State transition testing uses a model of the states the component may occupy, the transitions between those states, the events which cause those transitions, and the actions which may result from those transitions. Before component testing may begin the component test strategy 2. Test cases are designed to exercise valid transitions between states. A simple subpath is a subpath through a component’s control flow graph where no parts of the subpath are visited more than necessary.

Other test case design techniques may be used that are not listed in this clause. Test cases may also be designed to test that invalid output values cannot be induced. The faster, easier way to work with standards.

Each test case shall be specified by defining its objective, the initial state of the component, its input, and the expected outcome. Any alternative techniques used shall satisfy these criteria: No coverage measure is defined for random testing. Test cases shall be designed to 7925–2 values both on and next to the boundaries of the partitions. A working party was formed in January with a more formal constitution.


At the time of publication, the edition was valid. This Standard does not prescribe which test measurement techniques are to be used. The target audience for this Standard includes: This measure is defined with respect to the traversal of the set of subpaths from 792-2 variable definition to every c-use of that definition.

If techniques not described explicitly in this clause are used they shall comply with the ‘Other Testing Techniques’ clause 3. Statement testing uses a model of the source code which identifies statements as either executable or non-executable. Data definition C-uses are all others, including variable occurrences in the right hand side of an assignment statement, or an output statement.

Each test case shall include: This Standard defines a generic test process. This b include specific identification of all exceptions to the component test strategy and all software with which the component under test will interact during test execution, such as drivers and stubs.

August Replaced By: This Standard defines test case design techniques and test measurement techniques. Branch Condition Coverage is only defined for components with one entry point.

Boundary Value Analysis uses a model of the component that partitions the input and output values of the component into a number of ordered sets with identifiable boundaries. This measure is defined with respect to the traversal of the set 7925- subpaths from each variable definition to every use both p-use and c-use of that definition.


Branch Condition Combination Coverage 4. The input and output values are derived from the specification of the component’s behaviour. Coverage is calculated as follows: If measures not described explicitly in this clause are used they shall comply with the ‘Other Test Measurement Techniques’ clause 4.

The coverage items are the boundaries of partitions described by the model see 3. Coverage items are sequences of one or more transitions between states on the model see 3. Coverage items are executable statements in the source code. Test cases shall be chosen randomly from the input domain of the component according to the input distribution.

Test cases with valid syntax shall be designed to execute options which are derived from rules which shall include those that follow, although additional rules may also be applied where appropriate: The previous edition was working draft 3.

Aims of the standard. Coverage items are Boolean operand values within decision conditions. Coverage items are the partitions described by the model see 3.

Cause-Effect Graphing uses a model of the logical relationships between causes and effects for the component. Test cases are designed to exercise valid boundary values, and invalid input boundary values.
