Using dataprovider on the suite level.

[christoffer]

Hi i have a situation where the tests in a suite are dependent on
having the same data.

I have data1,data2,data3...dataN
and test1,test2...... testN

Now i need the testsuit to run this order

test1 with data 1
test 2 with data1
.......
testN with data1

and then
test1 with data 2
test 2 with data 2
.....
testN with data 2

and so on untill i hit dataN

If i put the @dataprovider on the test level i cannot be garanteed
that this hapens.
is there a way to get the dataprovider to the suite level so the data
is only read onse for each iteration of the suite and passed to each
test in the suite ?

best regards

I would be interested in the same thing. I have a DataProvider (returning a Iterator<Object[]>), with some heavy computation per iteration. To avoid repeating the computation, I would like to feed each iteration of the data-provider to multiple @Test method. With the option of feeding @Test method sequential/parallel.

 

Is it possible with current version of TestNG?

Did you ever figure this out? I'm coming across the same problem right now and trying to come up with a workaround. I'll let you know if I get anything.

Why don't you use memoization?
Introduce a data structure to store the results of the computation;
make the data provider run the computation and store the results
only if no results are yet available.

I guess computation is probably the wrong word to use, as each iteration of the DataProvider also sets up external test equipment. Can't use memoization for that.
