Methods of Class CL_ABAP_UNIT_ASSERT

Start ABAP Unit Tests in Test Methods of procedures to be tested and then check if an expected effected has taken place. Using the methods of class CL_ABAP_UNIT_ASSERT, the test method can ensure that the expectations are fulfilled.

If a test does not meet the test expectations, the errors are logged and displayed in the Test Evaluation. Optional input parameters for the methods control the individual behavior.

Class CL_ABAP_UNIT_ASSERT contains the following methods for checking test expectations:

• ASSERT_EQUALS

  Checks the deflection if two objects are the same. The objects must have a comparable type. A deeper comparison is executed, that is, tables and structures (even nested ones) are checked for the content of their components.

  Standard method in test classes generated with the ABAP Unit Wizard.

  The method can be enhanced to make complex Checks of ABAP Object Instances vorzunehmen.

• ASSERT_DIFFERS

  Ensures the differences between two elementary data objects (type SIMPLE). A check error is triggered if the types of the data object cannot be converted into each other.

• ASSERT_BOUND

  Checks the validity of the reference of a reference variable by testing the ABAP property IS BOUND.

• ASSERT_NOT_BOUND

  Checks the non-validity of the reference of a reference variable by testing the ABAP property IS NOT BOUND.

• ASSERT_INITIAL

  Checks an object for its initial value by testing the ABAP property IS INITIAL.

• ASSERT_NOT_INITIAL

  Ensures that a data object does NOT have its initial value (check the ABAP property IS NOT INITIAL).

• ASSERT_CHAR_CP

  Ensures that a character string matches a simple pattern. Possible wildcards are asterisk (*) and question mark (?). Check regular expressions using the method ASSERT_TEXT_MATCHES.

• ASSERT_CHAR_NP

  Ensures that a character string does not match a simple pattern. Possible wildcards are asterisk (*) and question mark (?). Check regular expressions using the method ASSERT_TEXT_MATCHES.

• ASSERT_TEXT_MATCHES

  Ensures that a character string fulfills the conditions of a regular expression.

• ASSERT_TABLE_CONTAINS

  Ensures that a data object appears as a row in an internal table.

• ASSERT_NUMBER_BETWEEN

  Ensures that a numerical value lies within a specific value range.

• ASSERT_SUBRC

  Requires a specific value of the return value sy-subrc.

• ASSERT_EQUALS_FLOAT

  Ensures approximate equality of two floating point numbers. Valid data types are DECFLOAT and F.

• ASSERT_THAT

  Ensures that a data object fulfills the specified Conditions. For more information, see here.

• FAIL

  Terminates a test with an error.

• ABORT

  Terminates a test because test prerequisites are not specified.
