Check methods have the following import parameters:

Parameter	Description
act	Variable to be checked
exp	Expected value (methods assert_equals, assert_differs)
msg	Message to be displayed in the log if the value does not match the expectation
lev	Gravity of error to be logged (class constants TOLERABLE, CRITICAL, FATAL)
quit	What is terminated if test fails (class constants NO, METHOD, CLASS, PROGRAM)

 

Check methods also have a return parameter, assertion_failed (value = ’X’ /SPACE). This can be used by the test method to find out the check results.

 

ABAP Unit Test Execution

To perform an ABAP Unit test, proceed as follows:

 

How to Perform an ABAP Unit Test

ABAP Workbench

• For a Program, on the menu bar choose Program → Execute → Unit Tests.
• For a Class, on the menu bar choose Class → Run → Unit Tests.
• In the Object Name screen area, right-click the item name and choose Execute → Unit Tests.

 

ABAP Development Tools (ADT)

• On the Project Explorer menu bar, choose Run → Run As → ABAP Unit Tests.

 

Tools for Mass Testing

• In the ABAP Test Cockpit (ATC), use check profile with checks BC_AUNIT, BC_AUNIT_M, or BC_AUNIT_L.
• In the Code Inspector (SCI), use check variant with check List of Checks → Dynamic Tests → ABAP Unit.

 

ABAP Unit Test Results

Although the tests may be carried out differently, the results are presented in a similar way.

 

On the left side of the figure, there is a list of the tests executed (test methods grouped by test classes). A red light indicates the classes and methods with errors. When you choose an entry with a red light, a list of errors is displayed in the Alerts and Messages screen area on the right side. When you click an error message, the message details are displayed in the Analysis screen area. In the Analysis area you can navigate to the source code of the test method.

 

Test Fixtures

Private and Parameterless Methods in a Test Class

To create a fixture, implement the following private and parameterless methods in a test class:

Methods	Description
SETUP	Instance method, which is executed before every single test method of the class.
TEARDOWN	Instance method, which is executed after every single test method of the class.
CLASS_SETUP	Static method, which is executed once before the first test method of the class.
CLASS_TEARDOWN	Static method, which is executed once after the last test method of the class.
