How to write and use natural language scripts?

Back to User Guide Main Page

---

A natural language (NL) script is represented by a sequence of natural language instructions that are stored in a nls-file. When writing NL scripts, you should avoid using hardcoded test data - use value references instead and import test data from data files. The content of NL scripts looks like a nlxx file but lacks any header. Imagine you have written a NL script called "Create order.nls". Now you can reuse this script any time with different data. For this purpose different alternatives exist:

A) Using stage instruction "TestData"

A1)

XXID: Create order
TestData: StandardOrderData

Execute script "Create order".

A2)

XXID: Create order
TestData: OrderData_1

"Create order".

A3)

XXID: Create order
TestData: CustomizedOrderData

Create order.

These three A variants do the same: they all call an instruction that executes the named script.

B) Defining test data with script call.

B1)

XXID: Create order

Execute script "Create order" with "StandardOrderData".

B2)

XXID: Create order
TestData: name=Donald, age=49

"Create order" with "CustomizedOrderData".

B3)

XXID: Create order

"Create order" with "StandardOrderData" and
   name=Donald
   age=49
.

In the last two B variants two values of the imported StandardOrderData are overwritten in order to create a special test condition.
