According to IEEE Std 829 - 1998 Test Cases must contain the following information:

Test case specification

Purpose
To define a test case identified by a test design specification.

Outline
A test case specification shall have the following structure:
a) Test case specification identifier;
b) Test items;
c) Input specifications;
d) Output specifications;
e) Environmental needs;
f) Special procedural requirements;
g) Intercase dependencies.

The sections shall be ordered in the specified sequence. Additional sections may be included at the end. If some or all of the content of a section is in another document, then a reference to that material may be listed in place of the corresponding content. The referenced material must be attached to the test case specification or available to users of the case specification.
Since a test case may be referenced by several test design specifications used by different groups over a long time period, enough specific information must be included in the test case specification to permit reuse.
Details on the content of each section are contained in the following subclauses.


1.1 Test case specification identifier
Specify the unique identifier assigned to this test case specification.

1.2 Test items
Identify and briefly describe the items and features to be exercised by this test case.
For each item, consider supplying references to the following test item documentation:

a) Requirements specification;
b) Design specification;
c) Users guide;
d) Operations guide;
e) Installation guide.

1.3 Input specifications
Specify each input required to execute the test case. Some of the inputs will be specified by value (with tolerances where appropriate), while others, such as constant tables or transaction Files, will be specified by name. Identify all appropriate databases, Files, terminal messages, memory resident areas, and values passed by the operating system.
Specify all required relationships between inputs (e.g., timing).

1.4 Output specifications
Specify all of the outputs and features (e.g., response time) required of the test items. Provide the exact value (with tolerances where appropriate) for each required output or feature.

1.5 Environmental needs

1.5.1 Hardware
Specify the characteristics and configurations of the hardware required to execute this test case (e.g., 132 character  24 line CRT).

1.5.2 Software
Specify the system and application software required to execute this test case. This may include system software such as operating systems, compilers, simulators, and test tools. In addition, the test item may interact with application software.

1.5.3 Other
Specify any other requirements such as unique facility needs or specially trained personnel.

1.6 Special procedural requirements
Describe any special constraints on the test procedures that execute this test case. These constraints may involve special set up, operator intervention, output determination procedures, and special wrap up.

1.7 Intercase dependencies

List the identifiers of test cases that must be executed prior to this test case. Summarize the nature of the dependencies.
