Test Sequencing
Creating a Test Execution Order
You may leave the other defaults. This configuration will lead to a PASS
result in approximately half of the runs. The dialog box should look like
Figure 9-1.
Figure 9-1. The Sequence Transaction Dialog Box
Click OK to close the dialog box. You will see the transaction
test1 0 <= (.25) <= .5
on the first transaction bar. This means that test1 will pass if the
returned value is in the range from
0 to .5 with the end points included.
The expected result is about
.25.
FUNCTION: The default entry
testFunc(a) holds the actual
function that performs the test. In this case, replace the
default field with the
random()function. Random()
will return a
Real64 value between 0 and 1 simulating
a test result. This result will be compared to the test
specification.
The
random(low,high) object is located in the
Probability & Statistics category in the
Function & Object Browser box. Remember that
you can call this math function from any expression
field without actually using a
Formula object. If you
do not provide the parameters low and high, as shown
in this example, the function will use the default
parameters
0 and 1.
