You're welcome!
Hi Raghav - Both your videos 18 and 19 on reading data from Excel are very informative and great work as usual! In my project, we use single excel input file to store test data for the various test cases. For example, my excel input file will have 10 different rows containing test data for the different test cases - each test case row will have column names like Test Case Name, Test Data1, Test Data2....Test Data5...and finally there is a column called Execute with values 'Yes' or 'No'. How do I extract the data to my DataProvider only based on the Test Case Name and when Execute column has the value 'Yes'. The criteria here is not to extract all the data from Excel input file but only to extract data based on the test case name and execute column = Yes. Appreciate if you can give your guidance here.
Hi Bimlesh, you can create scripts to read your excel and get data corresponding to the column that has Execute=Yes. This is help you - ruclips.net/video/B4G2tMDYjRQ/видео.html
Thanks!

When i run the dataprovider class getting index 1 out of bounds for length 1
Ammu
The "index 1 out of bounds for length 1" error typically occurs when you're trying to access an element at an index that doesn't exist in an array or collection. Let's troubleshoot this issue in the context of TestNG and Selenium.
Here are some common reasons for encountering this error and potential solutions:
1. Data Provider Mismatch:
- The error message you provided mentions a data provider mismatch. This usually happens when the number of parameters in your test method doesn't match the number of data provider arguments.
- Ensure that the number of parameters in your test method matches the number of columns (arguments) returned by your data provider.
- Verify that the data provider method returns the correct number of arguments for your test method.
2. Data Provider Arguments:
- Check the data provider method (`dpMethod` in your case). It should return a 2D array (or an iterable collection) with the correct number of columns.
- Each row in the array corresponds to a set of arguments for your test method.
- Make sure the data provider method returns the expected number of columns (parameters) based on your test method signature.
3. Test Method Signature:
- Your test method (`myTest` in your example) should have the same number of parameters as the data provider method.
- Verify that the test method signature matches the data provider arguments.
4. Example Fix:
```java
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
public class DProvider {
@DataProvider(name = "data-provider")
public Object[][] dpMethod() {
return new Object[][] {
{2, 3, 5},
{5, 7, 9}
};
}
@Test(dataProvider = "data-provider")
public void myTest(int a, int b, int result) {
int sum = a + b;
// Your test logic here
// ...
// Assert.assertEquals(sum, result);
}
}
```
- In this example, the data provider returns three columns (arguments), and the test method `myTest` accepts three parameters.
5. Check Excel Data:
- If you're reading data from an Excel file, ensure that the data is correctly formatted and matches the expected number of columns.
- Verify that the Excel sheet contains the right number of columns for your test method.
Remember to validate the data provider, test method, and data source (Excel, CSV, etc.) to ensure consistency in the number of arguments.

Clear explanation.. I am able to login into my application with username and password but I m not able to get the next sheet inputs .. how to include more than one sheets?
Hi Sathya, you will need to call the sheet in your code and then get the contents
This can help ruclips.net/video/B4G2tMDYjRQ/видео.html
Very Well Explained
Thanks for watching Sabuhi
Hi Raghav pal, how are you?
I have another question to you : )
Scenario - This is how my excel looks like:
1° column - Customer name
2° column - Customer type
So there are many lines with this information!
-------------------------------------------------------------------------
My automation will not need "ALL" the excel information. lets say that the automation will find the exact customer name in the web application. Then with this information (Customer name) I need to read the excel to discover the Customer type.
My question is:
- How can I search for the exact meet customer name in the excel (using Apache POI ore any other API).
- After search, discover the index from the cell in the column 1
- And look to the same index but in the column 2
- Bring the content from the cell - column 2- and print it
than I will be able to decide what to do
E.g.
If ( CustomerName == partner)
{
Send this email
}Else{
Send a different email.
}
Can you help me with that ???
Thank you so much, your videos always help me a lot!!!!
Hi Gilson, once you are able to read and get the content from excel, you can add your conditions, for example if the customer name is found, record the row number and get value from the corresponding email column.

Hi Raghav,
Thanks, this video has good information.
I have a 10 excel sheets in a workbook, each excel having one testcase(20rows). How to get all sheets data and execute 10 testcases, Please help.
Hi Anil, you will have to give the logic in your code. You can either name the sheets same as the test cases and in the code switch to the sheet by test case name and then get the data.
hello sir its really this made me to learn very easily ..can you help me to where is should declare file path without hardcoding..i am making my own framework
Manish
Absolutely! Declaring file paths without hardcoding in your Selenium Java project for a custom framework is crucial for maintainability and flexibility. Here are some options to consider:
*1. Environment Variables:*
* Store file paths in environment variables like `TEST_DATA_DIR` or `CONFIG_FILE_PATH`.
* Access them within your code using `System.getenv(variableName)`.
* This approach is platform-independent and easily configurable during execution.
*2. Resource Files:*
* Place configuration files like `data.properties` or `config.yaml` inside your project's `resources` directory.
* Access them using `ClassLoader.getSystemResourceAsStream(fileName)`.
* This keeps your code clean and files readily available at runtime.
*3. Classpath Scanning:*
* Annotate your configuration files with a custom annotation like `@TestDataFile`.
* Use a custom scanner to identify all files with that annotation at runtime.
* This allows for dynamic discovery of configuration files without hardcoding paths.
*4. Dependency Injection:*
* Define an interface for fetching file paths and inject its implementation during runtime.
* Different implementations can provide paths based on environment or configuration files.
* This promotes loose coupling and allows for easy switching between different file sources.
*Additional Tips:*
* Use relative paths within your code whenever possible to avoid hardcoding absolute paths.
* Implement a utility class to handle file access and path resolution for consistent usage across your framework.
* Consider using libraries like Apache Commons IO or Jasypt for advanced file handling and decryption.
By choosing the approach that best suits your needs and coding style, you can ensure your Selenium Java framework is flexible and adaptable, with file paths declared dynamically without hardcoding.
Remember to choose an approach that balances readability, maintainability, and security based on your specific project requirements.

Hi Raghav:
It is a good video for DataProvider. One question what if our requirement is reading cell data from all rows instead from first row? How to dynamically give the row counter for for getColNumber method?
or Can we assume that the no of columns are equal to all the rows as it was for first row? Is this good approach?

@RaghavPal could you explain me if Excel sheet having string and numerical data using data provider concept with data formatter.
Hi Ravi
**Data provider** is a concept in automation testing that allows you to store test data in a centralized location. This makes it easy to reuse test data and to keep track of changes to the data.
**Data formatter** is a tool that can be used to format test data. This can be useful for converting data types, removing special characters, and other tasks.
To use data provider and data formatter with Excel sheet having string and numerical data, you can follow these steps:
1. Create an Excel sheet that contains the test data.
2. Identify the columns in the Excel sheet that contain string and numerical data.
3. Create a data provider that reads the data from the Excel sheet.
4. Create a data formatter that formats the data from the data provider.
5. Use the data provider and data formatter in your automation scripts.
Here is an example of how to use data provider and data formatter with Excel sheet having string and numerical data:
```
import { DataProvider, DataFormatter } from 'some-data-provider-library';
const dataProvider = new DataProvider('my-excel-sheet.xlsx');
const dataFormatter = new DataFormatter();
const testData = dataProvider.getData();
const formattedData = dataFormatter.formatData(testData);
// Use the formattedData in your automation scripts.
```
I hope this helps

Could you please help me how to read numeric and string Excel data using data provider concept
Hi Ravi
To read numeric and string Excel data using data provider concept in TestNG, you can use the following code:
```java
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
public class DataProviderTest {
@DataProvider(name = "data")
public Object[][] getData() {
return new Object[][] {
{1, "one"},
{2, "two"},
{3, "three"},
};
}
@Test(dataProvider = "data")
public void testDataProvider(int number, String text) {
System.out.println("number = " + number);
System.out.println("text = " + text);
}
}
```
This code will read the data from the Excel file and pass it to the test method as a 2-dimensional array. The first element in the array is the numeric data, and the second element is the string data.
To run the test, you can use the following command:
```
mvn test -Dtest=DataProviderTest
```
This will run the `DataProviderTest` class and the `testDataProvider` method. The `testDataProvider` method will be executed three times, once for each row in the Excel file.
Here are some additional details:
* The `@DataProvider` annotation is used to define a data provider.
* The `@Test` annotation is used to define a test method.
* The `getData()` method is used to get the data from the Excel file.
* The `testDataProvider()` method is used to run the test.
I hope this helps

Hi Yogesh, Pls check the video again, if you are using data provider you need to provide the parameters in the function. Also check the spelling and syntax again
Towards the end of video u had written selenium program. For three data there may be few valid login credentials and few invalid. In the same script how to implement different assertion statement for different scenarios?
In case the scenario is different than of course you will need different Test Cases for it.
Do you have any video for this or r u planning to make some video for the same scenario? It will help a lot to understand to approach to achieve this scenario
will do it soon
Thank you so much. Waiting for your video
Hi Raghav...if I HV testng, cucumber,POM, data driven using excel in my framework...wat type of framework will it be called
More likely a hybrid framework
@@RaghavPal thanks Raghav ,still.have doubt hw we called it as a hybrid as hybrid is data driven + keyword .. Correct me if I am wrong
Yes, so in your framework you are using cucumber can better call it BDD cucumber Data driven.
Great job but please activate automatic subtitles, thanks
Hi Canal, mostly videos get the subtitles automatically. Some videos do not get due to audio issues. I will check on this again
When I run the tesng excel dataprovider I am getting Launching excel dataprovider has encountered a problem reference to undefined variable name
Ammu
1. Undefined Variable Name Error:
- This error typically occurs when TestNG tries to resolve a variable name (such as an environment variable or system property) but cannot find it.
- It might be related to how TestNG handles environment variables or system properties during test execution.
2. Possible Solutions:
- Here are some steps you can take to resolve this issue:
- 1. Disable System Property Variables:
- In Eclipse, navigate to Preferences → TestNG → Maven.
- Uncheck the option for systemPropertyVariables.
- This step ensures that TestNG doesn't rely on system properties during test execution¹.
- 2. Enable Environment Variables:
- Check if the option for environmentVariables is enabled in your TestNG configuration.
- Navigate to Preferences → TestNG → Maven and ensure that environmentVariables is checked.
- If it's disabled, enable it and try running your tests again¹.
- 3. Clear Cached Data:
- Sometimes cached data can cause unexpected behavior.
- Clear any cached responses or temporary files related to your TestNG project.
- Restart Eclipse and try running your tests again.
- 4. Verify Excel Data Provider:
- Double-check your Excel data provider method.
- Ensure that the method name matches the one specified in your TestNG test class.
- If the method name is not explicitly specified, TestNG uses the method name as the data provider name by default³.
- 5. Check Excel Formulas and References:
- If your Excel file contains formulas or named ranges, verify that they don't have errors (such as #N/A, #REF!, etc.).
- Incorrect formulas or references can cause issues with data providers².
..
Thank you 🙏
Hi, Raghav
After trying your code, I am getting " NegativeArraySizeException " in Test Data method on line
Object data[][] = new Object[TotalRowCount -1][TotalColumnCount];
Can you help me with this ?
Hi Rajat, Sorry for late reply, NegativeArraySizeException occurs whenever an application tries to create an array with negative size.
For example, whenever we assigned the negative size to an array.
int[ ] arr=new int[-10]; , Here the array size is -10 i.e., negative size.
You can try to print the TotalRowCount. I doubt you are getting a 0 value there

Hi Pratheep, so basically you need to run a test or scenario with diff test data. You can do it through excel or directly, Can use testng. This will help - ruclips.net/video/DDQbS9cy9bY/видео.html

How to get URL from From Single row row have more than 100 URLs one by one open this url and perform our test case
Hi Ashish
To get URLs from an Excel sheet and open each URL one by one for testing in Selenium Java framework with TestNG, you can follow these steps:
1. Read the Excel sheet: Use a library like Apache POI to read the Excel sheet and extract the URLs. Here's an example code snippet to read URLs from an Excel file:
```java
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import java.io.FileInputStream;
import java.io.IOException;
public class ExcelUtils {
public static Object[][] getURLsFromExcel(String filePath, String sheetName) throws IOException {
FileInputStream fis = new FileInputStream(filePath);
Workbook workbook = new XSSFWorkbook(fis);
Sheet sheet = workbook.getSheet(sheetName);
int rowCount = sheet.getLastRowNum() - sheet.getFirstRowNum();
Object[][] data = new Object[rowCount][1];
for (int i = 1; i

Hi Bro,
How can we use the @DataProvider in the large data set?
Hi Mani, the process should be the same. Just to avoid a lot of I/O operations with file, I will suggest to get data in memory using collections like maps, lists etc and then use it.
Hi Raghave,
Is this the same for appium?
Yes, it will work on appium projects too
