I created a data provider for a test case. It provides smaller and then longer arrays as an input for the test function. I would like to stop at the first error, because the error message gets harder to understand for larger inputs. But I would like to test for large inputs as well.
function testFunction(array $inputOne, array $inputTwo) {...}
function myDataProvider() {
return [
[[1,2], [3,4]],
[[1,2,3,4,5,6,7,8,9], [3,4,5,6,7,7,8,9,10]],
[<<LARGE ARRAY>>, <<LARGE ARRAY>>],
];
}
