Test Sequencing
Creating a Test Execution Order
Creating a Test Execution Order
In this lab you will simulate test results using the random() function,
establish a test execution order, learn how to modify that order, and retrieve
specific data from the logged results.
Lab 9-1: Configuring a Test
Note The example explains how to implement the random() function with a
certain range of test results expected, but you can use the same principles to
configure other tests.
1. Select
Device ⇒ Sequencer and place it in the upper-left work area.
2. Select
Display ⇒ AlphaNumeric display, place it below the
Sequencer, increase its width, and connect the Sequencer Log output
terminal to the
Alphanumeric data input.
3. Double-click the
Sequencer transaction bar to get the Sequence
Transaction
dialog box. Set the fields as follows.
Note As you edit the fields, remember to click on new fields to modify them or
use the
Tab key to move forward to different fields. Use the Shift-Tab keys
to move the cursor backward. Press the
Enter key only when you are done
editing the dialog box.
TEST: The default name is
test1, which you can use. This is
just the label for the test in the
Sequencer. It is not the
test function itself.
SPEC
NOMINAL:
Represents the expected test value. The default is
.5.
Change this to
.25, and then alter the upper RANGE
field (on the far right) from
1 to .5.
