DataProvider helps to send multiple sets of data to a test method. Passing multiple values is pretty similar to passing numerous parameters. The DataProviders in TestNG are another way to pass the parameters in the test function. Along with the introduction, we will learn the following to use TestNG dataproviders efficiently: The DataProviders in TestNG are another way to pass the parameters in the test function, the other one being TestNG parameters. Using DataProvider in TestNG, we can easily inject multiple values into the same test case. Observe the following test code, which checks if the sum of two integers is as expected or not. DataProviders help in passing the parameters in different ways. It is advisable when the data issmall and fixed for the test cases. Ideally, I would like my code to look like the following (simplified example): If you declare your @DataProvider as taking a java.lang.reflect.Method as first parameter, TestNG will pass the current test method for this first parameter. In the above example, I am passing two search keywords, viz Selenium and TestNG to the test method using the DataProvider method.

"thumbnailUrl": "https://i.ytimg.com/vi/dzXX2hJhuCY/maxresdefault.jpg", Note: Unlike parameters in TestNG, the dataproviders can be run directly through the test case file. This is particularly useful when several test methods use the same @DataProvider and you want it to return different values depending on which test method it is supplying data for. Lets now see when and how can we use the <@Parameters> annotationin TestNG projects. Any parameter value defined at the method level will override the value of a parameter, with the same name, if defined at the suite level.

I have named my package as testData under which I am saving my data excel file TestData.xlsx. So, my datasheet looks like below-, Next, we will create a DataProvider method that will use another method to read the excel file & create a 2D object from the row & column values of the excel and return the same value, so that our test script can use it. One of the important features of TestNG is parameterization. In the last tutorial, I have explain the Parameters in TestNG which passes different test data to the test case as arguments. If you want to put your data provider in a different class, it needs to be a static method or a class with a non-arg constructor, and you specify the class where it can be found in thedataProviderClassattribute. This is particularly useful when several test methods use the same @DataProvider and you want it to return different values depending on which test method it is supplying data for. Let's look into the implementation of @Factory in Selenium project. The output says that the variable value "Value Passed" was actually passed to the method. TestNG provide . The DataProvider method can be in the same test class or one of its superclasses. We have to pass the parameters to the test classes via a XML file.

A simple reason to use parameters is that they let us run a function many times with different values or to run different functions with the same values. The next article will brief you on the syntax of TestNG DataProviders. While writing test cases, the code tends to get very messy. It has built-in support for the data-driven testing and provides two ways to supply data to the test cases, i.e., via TestNG Parameters and DataProvider annotations.

Since I told this method that my dataprovider class is DP.java, I will create another file DP.java and write my dataprovider code there. We can use itfor parameter testing. Weve tried to cover as much as we could about theTestNG Parameters and DataProvider annotations along with their examples. How do I withdraw the rhs from a list of equations? Let us quickly understand it with the help of the code. Any @Before/@After methods are classified as configuration methods, which TestNG automatically runs before and after the @Test methods are executed. As you can see in the code above, we utilized DataProvider in TestNG to aggregate multiple values into a single parameter rather than assigning values one at a time. The method annotated with @DataProvider annotation return a 2D array or object. It also helps in providing complex parameters to the test methods. The first time the values of parameter data will be data one and the second time it will be data two. It also helps in providing complex parameters to the test methods.
