In a test method you call method cl_abap_unit_assert=>assert_equals( .. ) in the following way:

CLASS Itcl1 DEFINITION FOR TESTING RISK LEVEL HARMLESS DURATION SHORT.

PRIVATE SECTION.

METHODS m1 FOR TESTING.

ENDCLASS.

CLASS Itcl1 IMPLEMENTATION.

METHOD m1.

DATA: go_test_object TYPE REF TO zcl_to_be_tested.

CONSTANTS: Ico_exp TYPE string VALUE 'test2'.

CREATE OBJECT go_test_object.

cl_abap_unit_assert=>assert_equals(

EXPORTING

act = go_class->mv_attribute

exp = lco_exp

msg = 'assert equals failed ' && go_test_object->mv_attribute && ' ' && lco_exp

ENDMETHOD.

ENDCLASS.

What will happen if method parameters act and exp are not equal?



Answer : D


Question 2

What are valid statements? Note: There are 3 correct answers to this question



Answer : B, D, E

The following are the explanations for each statement:

C: This statement is valid. Class CL1 uses the interface. This is because class CL1 implements the interface ifl using the INTERFACES statement in the public section of the class definition. The INTERFACES statement makes the class compatible with the interface and inherits all the components of the interface.The class can then use the interface components, such as the method ml, by using the interface component selector ~, such as ifl~ml12

E: This statement is valid. Class CL1 implements the interface. This is because class CL1 implements the interface ifl using the INTERFACES statement in the public section of the class definition. The INTERFACES statement makes the class compatible with the interface and inherits all the components of the interface.The class must then provide an implementation for the interface method ml in the implementation part of the class, unless the method is declared as optional or abstract12

D: This statement is valid. In class CL2, the interface method is named ifl~ml. This is because class CL2 has a data member named m0_ifl of type REF TO ifl, which is a reference to the interface ifl. The interface ifl defines a method ml, which can be called using the reference variable m0_ifl.The interface method ml has the name ifl~ml in the class, where ifl is the name of the interface and the character ~ is the interface component selector12

The other statements are not valid, as they have syntax errors or logical errors. These statements are:

A: This statement is not valid. In class CL1, the interface method is named ifl~ml, not if-ml. This is because class CL1 implements the interface ifl using the INTERFACES statement in the public section of the class definition. The interface ifl defines a method ml, which can be called using the class name or a reference to the class. The interface method ml has the name ifl~ml in the class, where ifl is the name of the interface and the character ~ is the interface component selector.Using the character - instead of the character ~ will cause a syntax error12

B: This statement is not valid. Class CL2 does not use the interface, but only has a reference to the interface. This is because class CL2 has a data member named m0_ifl of type REF TO ifl, which is a reference to the interface ifl. The interface ifl defines a method ml, which can be called using the reference variable m0_ifl. However, class CL2 does not implement the interface ifl, nor does it inherit the interface components.Therefore, class CL2 does not use the interface, but only references the interface12


Question 3

Which of the following are incomplete ABAP types? Note: There are 2 correct answers to this question.



Answer : C, D

Incomplete ABAP types are types that do not specify all the attributes of a data type, such as the length, the number of decimal places, or the value range. Incomplete types can only be used for the typing of field symbols and formal parameters, not for the definition of data objects or constants.Incomplete types can be either predefined or user-defined1.

The following are incomplete ABAP types:

C . C is a type for character strings with a generic length. The length of the character string has to be specified when a data object or a constant is defined with this type.For example, DATA text TYPE c LENGTH 10 defines a data object named text with a type c and a length of 10 characters2.

D . P is a type for packed numbers with a generic length and a generic number of decimal places. The length and the number of decimal places of the packed number have to be specified when a data object or a constant is defined with this type.For example, DATA amount TYPE p LENGTH 8 DECIMALS 2 defines a data object named amount with a type p, a length of 8 bytes, and 2 decimal places3.

The following are not incomplete ABAP types, because they specify all the attributes of a data type:

A . String is a type for variable-length character strings. The length of the character string is determined at runtime and can vary from 0 to 2,147,483,647 characters. The length does not have to be specified when a data object or a constant is defined with this type.For example, DATA text TYPE string defines a data object named text with a type string and a variable length4.

B . T is a type for time values in the format HHMMSS. The length of the time value is fixed at 6 characters and does not have to be specified when a data object or a constant is defined with this type. For example, DATA time TYPE t defines a data object named time with a type t and a length of 6 characters.


Question 4

Which of the following ON conditions must you insert in place of "???"?



Answer : D

The correct ON condition that must be inserted in place of ''???'' is:

ON Sprojection.carrier_id=Z_Source2.carrier_id

This ON condition specifies the join condition between the CDS view Sprojection and the database table Z_Source2. The join condition is based on the field carrier_id, which is the primary key of both the CDS view and the database table.The ON condition ensures that only the records that have the same value for the carrier_id field are joined together1.

The other options are not valid ON conditions, because:

A . ON Z_Sourcel.camer_id = 7_Source2 carrier_id is not valid because Z_Sourcel and 7_Source2 are not valid data sources in the given code. There is no CDS view or database table named Z_Sourcel or 7_Source2. The correct names are Z_Source1 and Z_Source2. Moreover, the field camer_id is not a valid field in the given code. There is no field named camer_id in any of the data sources. The correct name is carrier_id.

B . ON Sprojection Camer=Source2 carrier_id is not valid because Sprojection and Source2 are not valid data sources in the given code. There is no CDS view or database table named Sprojection or Source2. The correct names are Sprojection and Z_Source2. Moreover, the field Camer is not a valid field in the given code. There is no field named Camer in any of the data sources. The correct name is carrier_id.Furthermore, the ON condition is missing the dot (.) operator between the data source name and the field name, which is required to access the fields of the data source1.

C . ON Sprojection. Carrier Source2.carrier is not valid because Carrier and carrier are not valid fields in the given code. There is no field named Carrier or carrier in any of the data sources. The correct name is carrier_id.Moreover, the ON condition is missing the dot (.) operator between the data source name and the field name, which is required to access the fields of the data source1.


Question 5

In ABAP SQL, which of the following retneves the association field _Airline-Name of a CDS view?



Answer : B


Question 6

For the assignment, gv_target = gv_source.

which of the following data declarations will always work without truncation or rounding? Note: There

are 2 correct answers to this question.



Answer : B, C

The data declarations that will always work without truncation or rounding for the assignment gv_target = gv_source are B and C. This is because the target data type string is a variable-length character type that can hold any character string, including those of data types c (fixed-length character) and d (date).The assignment of a character or date value to a string variable will not cause any loss of information or precision, as the string variable will adjust its length to match the source value12.

You cannot do any of the following:

A . DATA gv_source TYPE string, to DATA gv_target TYPE c.: This data declaration may cause truncation for the assignment gv_target = gv_source. This is because the target data type c is a fixed-length character type that has a predefined length.If the source value of type string is longer than the target length of type c, the source value will be truncated on the right to fit the target length12.

D . DATA gv_source TYPE p LENGTH 8 DECIMALS 3. to DATA gv_target TYPE p LENGTH 16 DECIMALS 2.: This data declaration may cause rounding for the assignment gv_target = gv_source. This is because the target data type p is a packed decimal type that has a predefined length and number of decimal places.If the source value of type p has more decimal places than the target type p, the source value will be rounded to the target number of decimal places12.


Question 7

In ABAP SQL, which of the following can be assigned an alias? Note: There are 2 correct answers to this question.



Answer : B, C

In ABAP SQL, an alias is a temporary name that can be assigned to a field or a database table in a query. An alias can be used to make the query more readable, to avoid name conflicts, or to access fields or tables with long names.An alias is created with the AS keyword and is only valid for the duration of the query1.

The following are examples of how to assign an alias to a field or a database table in ABAP SQL:

B . field (from field list): A field is a column of a table or a view that contains data of a certain type. A field can be assigned an alias in the field list of a SELECT statement, which specifies the fields that are selected from the data source. For example, the following query assigns the alias name to the field carrname of the table scarr:

SELECT carrid, carrname AS name FROM scarr.

The alias name can be used instead of carrname in other clauses of the query, such as WHERE, GROUP BY, ORDER BY, and so on2.

C . database table: A database table is a collection of data that is organized in rows and columns. A database table can be assigned an alias in the FROM clause of a SELECT statement, which specifies the data source that is selected from. For example, the following query assigns the alias c to the table scarr:

SELECT c.carrid, c.carrname FROM scarr AS c.

The alias c can be used instead of scarr in other clauses of the query, such as WHERE, JOIN, GROUP BY, ORDER BY, and so on3.

The following are not valid for assigning an alias in ABAP SQL:

A . order criterion (from order by clause): An order criterion is a field or an expression that is used to sort the result set of a query in ascending or descending order. An order criterion cannot be assigned an alias in the ORDER BY clause of a SELECT statement, because the alias is not visible in this clause.The alias can only be used in the clauses that follow the clause where it is defined1.

D . group criterion (from group by clause): A group criterion is a field or an expression that is used to group the result set of a query into subsets that share the same values. A group criterion cannot be assigned an alias in the GROUP BY clause of a SELECT statement, because the alias is not visible in this clause.The alias can only be used in the clauses that follow the clause where it is defined1.
