Isn't the error message self-explanatory?
The data provider is trying to pass 4 parameters but the method plus.gmail#glogin takes 2
Use a debugger and figure out why your data provider is returning 4 parameters instead of just 2.
Question
I started learning Selenium2 (WebDriver) with Eclipse and TestNG. I have a question about DataProvider. I have a login page having user, password and login button for example. I have written a test in TestNG. I have used pageobject for UI objects (have separate class) and actual test in another class.
Here glogin is a class and login is the function where finding elements and sending keys is done and this is called in another class gtest(which is main test) which has TestNG annotations.
I access that class in main script which will take values.
@test(Dataprovide = "test")
public void glogin(String user, String pass)
{
glogin log1 = new login;
log1.login(user,pass);
}
I have the following excel sheet
user pass

Carson Black

test test4
When I use dataprovider and get data from the excel sheet as array and use it in Test then the following error is displayed:
org.testng.TestNGException:

Any help is really appreciated.
Here is code for method annotated with Dataprovider and
@DataProvider(name="test")
public Object[][] createdata1()throws Exception
{
Object[][] retobj = getexcel();
return retobj;
}
private String[][] getexcel() throws Exception
{
// TODO Auto-generated method stub
String[][] tabarray = null;
try {
Workbook wb1 = Workbook.getWorkbook(new
File("F:/testdata.xls"));
Sheet sheet = wb1.getSheet("userlogin");
Cell tablestart = sheet.findCell("login");
int startrow = tablestart.getRow();
int startcol = tablestart.getColumn();
Cell tableend = sheet.findCell("login",startcol+1,startrow+1,
100, 64000, false);
int endrow = tableend.getRow();
int endcol = tableend.getColumn();
System.out.println("startRow="+startrow+", endRow="+endrow+",
" + "startCol="+startcol+", endCol="+endcol);
tabarray = new String[endrow - startrow + 1][endcol -
startcol + 1];
int ci = 0;
for(int i = startrow +1 ;i<endrow;i++,ci++)
{
int cj = 0;
for(int j = startcol + 1;j<endcol;j++,cj++)
{
tabarray[ci][cj] = sheet.getCell(j,
i).getContents();
System.out.println(tabarray[ci][cj]);
}
}
} catch (BiffException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return tabarray;
}
test(Dataprovider = "test")
public void glogins(String user, String pass)
{
glogin log1 = new glogin(driver);
log1.login(user,pass);
}
When I executed the test, I received data from excel as
john
smith
carson
Black
carla
ck23
test
test4
as output

Use a debugger and figure out why your data provider is returning 4 parameters instead of just 2.
Use
tabarray = new String[endrow - 1][endcol - 1]; instead of //tabarray = new String[endrow - startrow + 1][endcol - startcol + 1];
Because you intended to return only 2*2 array
Replace the line
tabarray = new String[endrow - startrow + 1][endcol - startcol + 1];
with
tabarray = new String[endrow - startrow - 1][endcol - startcol - 1];
I agree with the response posted by Kalyan; the reason being the first and last column of the data provider excel sheet is also counted in as arguments / parameters by the function; therefore please use tabArray=new String[endRow-startRow-1][endCol-startCol-1];
Hope this helps and happy testing...
