You can pass values to a test case at runtime in import parameters which can, e.g. be put in transaction input fields. This makes use of test cases flexible.

You can store sets of values which you often want to pass to the import parameters at runtime, in variants. You then only need to specify the variant name at test case runtime.

Before you can create test case variants, you must have cresated test cade import parameters.

There are two types of variants, which only differ in their maintenance:

• internal variants: maintained in R/3
• external variants: maintained outside R/3 with an external program (e.g. MS Excel). Data is passed in a text file.

When a variant runs, the system checks for each import parameter whether a value is defined for it in the variant. If so, this value is passed to the parameter at runtime. Otherwise, the parameter default value is used. If there is no default value, the parameter has the initial value.

You can use the following values to define variants:
