1-3 Input/Output Data of Test Method
Program
The test method program (one function for a test suite) can handle
two kinds of input data and two kinds of output data between the
test method program and the outside of it:
Input Data:
Input parameter of a test method program
•
You can carry any data such as a pin name and so on from the
outside of the program as the input parameters of the test method
program. To carry the data from the outside to a test method
program, you have to define a variable for each data before
starting the development of each test method program. Also, you
can add or modify the input parameter definition afterward. The
variable definition of the input parameters is done in the
Parameter and Limit Table dialog window of the Test Method
Editor. And entering the input parameter values is done in the
Parameter dialog window of the Test Flow Editor before the test
execution. For these dialog windows, see
• Limit data
The limit data is used to judge whether a test result is pass or fail.
The limit data is specified from the outside of the program
generally. To carry the limit data from the outside to a test method
program, you have to define an identifier (called the test name)
before starting the development of each test method program. Also
you can add or modify the identifier definition afterward. The
identifier definition and entering the limit values are done in the
Parameter and Limit Table dialog window of the Test Method
Editor and the Parameter dialog window of the Test Flow Editor
as same as above. In the test method program, the TEST API has
to be used for judgement. The TEST API looks up limit values that
were entered in the Parameter dialog, corresponding to the
identifier (test name parameter) specified in this function. For
more information related to the limit data and TEST API, see
"Judgement API" on page 423.
Output Data:
Output parameter of a test method program
•
You can carry up to four data to the testflow as the output
parameter of the test method program. Only one variable
(_result[4]) for the output parameter is defined by the system
automatically. Hence, you don't have to define for the output
