Re: [testng-users] Merge Multiple DataProviders into Single one and then feed the merger DataProvider to Test
Cédric Beust ♔
Hello All,
I have an requirement to merge the DataProviders and then feed to the Test
Steps :
@DataProvider
public Object[][] getData1() {
Object[][]a=TestUtil.getData(emp1xls, "TestCase_A3");
return a;
}
@DataProvider
public Object[][] getData2() {
Object[][]b=TestUtil.getData(emp1xls, "TestCase_A3");
return b;
}@DataProvider
public Object[][] merge(){
a+b
}
@Test(dataProvider="merge")
public void test(String Col1,String Col2.....){
}
if any one has idea , please share.
Thanks
Shaik

Hey - looks like this what my Cartesian Data Provider did:
http://www.theoryinpractice.net/post/29190379586/cartesian-data-providers
I never did get around to seeing if I could rip out the Guava dependency to submit it upstream did I?
Shaik - does this help you?

Ah, close - but you could probably adopt the code to get what you want. From what I can see, you're basically wanting a simple "zip" operation like you find in a lot of functional programming languages:
1) for each next Object[] in EACH request dataset
2) construct a new Object[], combing the two above
3) add that to a new collection
4) use it :)

The code that uses it looks like this (with [...] parts cut out):
@DataProvider
Iterator<Object[]> a() {
[...]
return Iterators.forArray(new Object[][] {{ [...] }};
}
@DataProvider
Iterator<Object[]> b() {
[...]
return [...];
}
@DataProvider
Iterator<Object[]> c() {
return new DataProviderExtender<String>().combined(
a(), b());
}
@DataProvider
Iterator<Object[]> d() {
[...]
return [...];
}
@DataProvider
Iterator<Object[]> e() {
return new DataProviderExtender<String>().combined(
c(), d());
}
DataProviderExtender.java:
package [...];
import java.util.Iterator;
import org.testng.internal.collections.Pair;
public class DataProviderExtender<T> {
public Iterator<Object[]> combined(final Iterator<Object[]> dp,
final Iterable<T> xtra) {
return new Iterator<Object[]>() {
private final Iterable<Object[]> sites_and_browsers = new Iterable<Object[]>() {
@Override
public Iterator<Object[]> iterator() {
// TODO Auto-generated method stub
return dp;
}
};
private final Iterable<Pair<Object[], T>> product = new CartesianProduct<Object[], T>(
sites_and_browsers, xtra);
private final Iterator<Pair<Object[], T>> pairs = product
.iterator();
@Override
public boolean hasNext() {
return pairs.hasNext();
}
@Override
public Object[] next() {
Pair<Object[], T> p = pairs.next();
return new Object[] { p.first()[0], p.first()[1],
p.second() };
}
@Override
public void remove() {
throw new UnsupportedOperationException();
}
};
}
}
It's not pretty, but it works.
Now if I could get right-clicking on the tests that use these
(to rerun them with the same parameters) to work,
I'd be a happy man.

For those of you who need a tool for merging data providers and feeding a test with the merged data, you can have a look to the following post:
