!3 You are allowed to pass arguments into any fixture.
|
||
|
|
|
||
|
|
Arguments are in cells that are to the right of the cell with the fixture name. The protected field ''args'' in Fixture holds a String array with the arguments.
|
||
|
|
|
||
|
|
Below you can see a simple RowFixture that takes a single integer argument and produces the prime factors of that argument.

|
||
|
|
The code for this fixture is shown below. Note that the ''query'' method uses the ''args'' field.
|
||
|
|
(Note the "6" that follows the fixture name above.) You can put as many arguments there as you like.

Because this is a RowFixture, the order of the rows is unimportant. As shown below the rows will be matched and found regardless of their order.
