We would like to run some of our tests each against a set of data values, verifying that the same conditions hold true for each. The data is currently stored in either flat files or in simple Excel spreadsheets.
My first thought was to create a TestNG DataProvider that would load the data from the file and be used to call the test method once for each data value. My problem is that different tests need to load data from different files and there doesn't appear to be any way to send a parameter to the DataProvider. Does anyone know if this is possible?
Ideally, I would like my code to look like the following (simplified example):
public class OddTest {
@DataProvider(name = "excelLoader")
public Iterator<Object[]> loadExcelData(String fileName) {
...
}
@Test(dataProvider = "excelLoader" dataProviderParameters = { "data.xls" })
public void checkIsOddWorks(int num)
assertTrue(isOdd(num));
}
}
