Dashboard in the Unit Test View

Menu	Description
	Runs unit tests.
	Shows success, failure, error and total of test case.
	Selects the coverage type to be displayed in the Unit Test View. (statement, branch, MC/DC, function call)
	Shows the selected kind of full coverage.

Search

In the Unit Test View, you can search functions, tests and test cases by file, function, test, status (success, failure, error) and issue name.

Status search keyword

In the Unit Test View, you can filter the tests that are displayed by the status search keyword. It provides searchable keyword recommendation and auto-complete function.

Keyword	Description
%TEST_SUCCESS%	Test success
%TEST_FAILURE% %TEST_ERROR%	Test failure/error
%TEST_FAILURE%	Test failure
%TEST_ERROR%	Test error
%TEST_HAS_NOT_FUNCTION%	Function changed
%TEST_NOT_GUARANTEE%	Run not guaranteed
%TEST_RESULT_DIFFERENT%	Host/Target result different

*‘Run not guaranteed’ is a case where test code is generated, but there is no guarantee that it will run normally. This is the case when using a type that is difficult to specify as a parameter or return value.

Structure of the Unit Test View

The Unit Test View presents the hierarchy structure of [Function] > [Test] > [Test case]. If there are more than 100 test cases in a test, they are grouped in groups of 100 to represent a group.

Item status color in the Unit Test View

The execution information of functions, tests, and test cases in the Unit Test View is represented by colors.

Color	Description
Green	Function/Test: If the execution result of all the test cases under it is success. Test case: The result of execution is success.
Blue	Function/Test: If only test cases with failure and no test cases with errors exist under it. Test case: The result of execution is failure.
Red	Function/Test: If test cases with error exist under it. Test case: The result of execution is error.
Orange	Function/Test: All test cases have not been executed under it and test cases that are not guaranteed to run exist. Test case: Run not guaranteed.
Black	Function/Test: All test cases under it have not been executed. Test case: Not been executed.

Function

The functions provide the function name, the coverage and the test case execution results (success, failure, error and total).

*For the coverage for each function, the test execution result of the other function may be applied depending on the call relationship between functions.

• Rule for importing test data
  When importing the test data, if you select multiple test data numbered with the test name, it imports those files by merging them.

*For [Test reconfiguration], refer to [Source Code Modification and Test Reconfiguration]

Import test data

You can import the test data in various formats (csv, xlsx, txt, json).

1. In the context menu of the Unit Test View, click [Import Test Data] and select either [Basic format data] or [External format data].
2. If you select [Basic format data], the test data with the format (csv) exported from the CT 2023.12 is imported.
3. If you select [External format data], the test data is imported from the files in various formats (csv, xlsx, txt, json).

Generate test cases automatically

It creates a test case by using [Flat/Pairwise/Random combination], [Generates with Function Generator], and [Search-based Test case Generation (CS Labs)].

1. In the context menu of the Unit or the Integration Test View, click [Generate test cases automatically] and select one among [Flat Combination], [Pairwise Combination], [Random Combination], [Generate with Function Generator] and [Search-based Test case Generation (CS Labs)].

Method	Description
Flat	Combines simply based on variables having the largest number of test data.
Pairwise	Combines so that each selected parameter data is paired at least once with the parameter data other than itself. ※ The number of variable partitions must be more than 2 and less than 52.
Random	Combines the test data as many as the number of test cases that the user defines any value between the minimum value and the maximum value for the variable partition of input parameters.
Generate with Function Generator	Creates a test case by using six function types. (Ramps, Random, Range, Sine, Toggle, and Single Value)
Search-based Test case Generation (CS Labs)	Creates a test case by using AVM, which is a local search algorithm. ※ Currently, only C language is supported.

2. If you select [Random combination], the Random combination window is displayed so that the user can enter the number of test cases.

3. If you select [Generate with Function generator], you can select the function type (Ramps, Sine, Random, Toggle, Range, Single value and None) and change the settings of the function selected via the settings of the function generator. In the properties window of the project, you can set the function generator information in [Test] > [Generate test cases automatically] > [Function Generator].

a. Common settings

You can change the value in [Project] > [Properties] with the setting value common to each function.

Setting	Description
Sample interval	The interval of samples to be sampled from the function.
Number of sample	The number of samples to be sampled from the function(The number of test cases).

Minimum value of type	The minimum value of variable partition. (If the return value of the function is less than the minimum value of type, the minimum value of type is returned.)
Maximum value of type	The maximum value of variable partition. (If the return value of the function is greater than the maximum value of type, the maximum value of type is returned.)

b. Ramps function

It is a function that creates a pulse by using Pre, Post and Hold values. If the number of samples is greater than the period of the function, the function is called recursively.

It is a function that creates a random value between the minimum value (Min) and the maximum value (Max).

Setting	Description
Min	The minimum value of random range.

Alternate	If the result value of function meets the minimum/maximum value of type, the function type that changes to rise or fall. Ex) if the step size is 30 and the maximum/minimum value are 0~100, 0,30,60,90,60,30,0……

e. Sine function

It is a function that creates Sine value. If the number of samples is greater than the period of the function, the function is called recursively.

h. None

It does not create a function.

Relevant issues settings

It associates the selected test with the issue in the issue management tool registered. The CT 2023.12 supports the following issue management tools: JIRA, Trac, Redmine, Mantis, Bugzilla.

1. In the context menu of Unit Test View, click [Relevant issues settings…].
   
2. Enter the information of the issue management tool in the configuration file (IssueManagement.ini).
