Variable expected value expressions

The expected expressions are used to specify a test criteria by comparison with the value of a variable. The test receives a passed verdict when the actual obtained value matches the expected value expression.
The expected expressions can be among any of the following values:
  • Numeric (integer or floating-point), character, or character string literal values. Strings can be delimited by single or double quotes.
  • Native constants, which can be numeric, characters, or character strings.
  • Ranges with lower and upper values and inclusive or exclusive bounds.
  • Global variables that are declared by the program under test.
  • A null pointer or a non-null pointer.
  • Arrays and structures, any of the above-mentioned expressions between braces ('{}').
  • C functions or expressions with one or more of the above elements combined using any operators and casting, with all required levels of parentheses. The + operator allows to concatenate character string variables.
  • No Check, which specifies that no check is performed on that variable.
  • Same As Init, which specifies that the expected variable equals the initialization expression.
  • Data sets that are synchronized with a multiple initialization expression.

The data type of the variable defines the acceptable values for the expected value.

Numeric values can be associated with a comparison operator in the test case editor.

Expected expressions can be synchronized, which means that a list of multiple values for one variable will be synchronized with a matching number of values for another variable. See Synchronizing multiple values for more information.

Additional notes

Any integers contained in an expression must be written either in accordance with native lexical rules, or under the form:
  • hex_integerH for hexadecimal values. In this case, the integer must be preceded by 0 if it begins with a letter.
  • binary_integerB for hexadecimal values.

Ranges are not allowed for pointers.

The number of values inside an expected expression is limited to 100 elements in a single variable.

If variables are used in the expected expression, the test evaluates the initialization value with variable values from after the execution.

Euclidean divisions performed by the test case round to the inferior integer. Therefore, writing -a/b returns a different result than -(a/b), as in the following examples:
  • -(9/2) returns -4
  • -9/2 returns -5
