How to read excel file in cucumber project? - testing

Question

I am creating testing automation framework using java but i am not able to read excel file in cucumber.
is there any way to use #DataProvider functionality og testNG?
I do not want to use datatable of feature file.

Answer 1

If you use CucumberJVM, I don't think you can make use of TestNG Data Providers without major hacks. Or at least this is not a "cucumber way" of doing things. Data Table is a Cucumber equivalent of TestNG Data Provider:
https://cucumber.io/docs/reference#data-tables
This is how you parametrise tests in Cucumber. I'm not saying the solution you are looking for can't be implemented, I'm saying you are most likely looking for a wrong thing. CucumberJVM makes use of DataProviders internally, to handle features this way:
https://github.com/cucumber/cucumber-jvm/blob/master/testng/src/main/java/cucumber/api/testng/AbstractTestNGCucumberTests.java

In case it helps others:
here is described how to link a Cucumber Scenario Outline to read data from an Excel file
https://startingwithseleniumwebdriver.blogspot.com/2017/04/getting-data-from-external-file-using.html
and here is described how to load data from an Excel file in a Cucumber feature file before executing Scenario steps
https://startingwithseleniumwebdriver.blogspot.com/2017/04/loading-data-from-external-file-to.html
I my case this was very useful, as for each Scenario step I had to load Excel data (data from multiple rows having same group ID) in order to perform further validations. Like this the Cucumber feature file was a bit cleaner while the Excel had all the details under the hood.

ExcelBDD Java edition can resolve this problem gracefully. code example
static Stream<Map<String, String>> provideExampleList() throws IOException {
String filePath = TestWizard.getExcelBDDStartPath("excelbdd-test")
+ "excelbdd-test\\src\\test\\resources\\excel.xlsx";
return Behavior.getExampleStream(filePath,"Expected1","Scenario1");
}
#ParameterizedTest(name = "Test{index}:{0}")
#MethodSource("provideExampleList")
void testgetExampleWithExpected(Map<String, String> parameterMap) {
assertNotNull(parameterMap.get("Header"));
System.out.println(String.format("=======Header: %s=======", parameterMap.get("Header")));
for (Map.Entry<String, String> param : parameterMap.entrySet()) {
System.out.println(String.format("%s --- %s", param.getKey(), param.getValue()));
}
}

Here is the example how to read TestData from excel
public class Framework {
static String TestDataPath = System.getProperty("user.dir")
+ "\\ExcelFiles\\TestData.xlsx";
public static HashMap<String, HashMap<String, String>> hm1 = new HashMap<>();
static String s3;
public static void ReadTestData() throws IOException {
FileInputStream file = new FileInputStream(TestDataPath);
XSSFWorkbook workbook = new XSSFWorkbook(file);
XSSFSheet sheet = workbook.getSheet("Sheet1");
Row HeaderRow = sheet.getRow(0);
for (int i = 1; i < sheet.getPhysicalNumberOfRows(); i++) {
Row currentRow = sheet.getRow(i);
HashMap<String, String> currentHash = new HashMap<String, String>();
for (int j = 0; j < currentRow.getPhysicalNumberOfCells(); j++) {
Cell currentCell1 = currentRow.getCell(0);
switch (currentCell1.getCellType()) {
case Cell.CELL_TYPE_STRING:
s3 = currentCell1.getStringCellValue();
System.out.println(s3);
break;
case Cell.CELL_TYPE_NUMERIC:
s3 = String.valueOf(currentCell1.getNumericCellValue());
System.out.println(s3);
break;
}
Cell currentCell = currentRow.getCell(j);
switch (currentCell.getCellType()) {
case Cell.CELL_TYPE_STRING:
currentHash.put(HeaderRow.getCell(j).getStringCellValue(),
currentCell.getStringCellValue());
break;
case Cell.CELL_TYPE_NUMERIC:
currentHash.put(HeaderRow.getCell(j).getStringCellValue(),
String.valueOf(currentCell.getNumericCellValue()));
break;
}
}
hm1.put(s3, currentHash);
}
Here is the Model cucumber file and testData.
Scenario Outline: Successful Login with Valid Credentials
Given User is on Home Page
When User Navigate to LogIn Page
And User enters mandatory details of "<TextCase>"
Then Message displayed Login Successfully
Examples:
|TextCase|
|Case1 |
|Case2 |
[Test data img Link][1]

Here is the Model Stepdefination File
#When("^User enters mandatory details of \"([^\"]*)\"$")
public void user_enters_mandatory_details_of(String arg1) throws Throwable {
// Write code here that turns the phrase above into concrete actions
driver.FindElement("UserName").sendKeys(Framework.hm1.get(arg1).get("UserName"));
Framework.FindElement("Password").sendKeys(Framework.hm1.get(arg1).get("Password"));
}
Follow above three steps in cucumber you will able to read test data.
