Am reading data from csv file , i have test for which this data will be the input . i want it to run as tescase for every set of value. for that am using data provider The problem is , it is taking only the last set row of data , please help me in debugging the code
For eg : if my csv has following data
name1 id1 text1
name2 id2 text2
name3 id3 text3
it taking only last row name3 id3 text3 and running the test only once not three times.
@DataProvider(name = "test")
public Object[][] provider( ) throws InterruptedException
{
Object[][] returnObject ;
String[] checkpoint = ReadfromCSV();
count = count + 1;
returnObject = new Object[][]{checkpoint };
return returnObject;
}
@Test(description = "Test", groups = "test" , dataProvider = "test")
public void compare(String val1,String val2,String val3,String val4,String val5,String val6,String val7,String val8,String val9,String val10,String val11 ) {
System.out.println("1:" + val1);
System.out.println("4:" + val2);
System.out.println("5:" + val3);
}
@SuppressWarnings("null")
public String[] ReadfromCSV() throws InterruptedException {
String[] data= null;
String csvFile = "F:/sample1.csv";
BufferedReader br = null;
String line = "";
String cvsSplitBy = ",";
try {
br = new BufferedReader(new FileReader(csvFile));
while ((line = br.readLine()) != null) {
// use comma as separator
data= line.split(cvsSplitBy);
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
if (br != null) {
try {
br.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
System.out.println("Done");
return data;
}

You should read entire file in data provider and return iterator of test cases. Here is some pseudocode for data provider. Notice that I used List<String []>
to store test cases instead of Object[][]
. This allows you do define test cases dynamically.
@DataProvider(name = "test")
public Iterator<Object []> provider( ) throws InterruptedException
{
List<Object []> testCases = new ArrayList<>();
String[] data= null;
//this loop is pseudo code
br = new BufferedReader(new FileReader(csvFile));
while ((line = br.readLine()) != null) {
// use comma as separator
data= line.split(cvsSplitBy);
testCases.add(data);
}
return testCases.iterator();
}
