Data Provider

Purpose

• The purpose of data provider is to allow rerunning of the same test with different data sets

• This is useful for validating forms with different data sets

Data Setup

• We first setup the data in a csv file under the "data" folder

• The first column is @id which identifies the data and the rest are data values

UserInvalid.csv

Implementation

• We generate the data object based on the csv file

• To Implement in the test, we first create a test method with data provider annotation

VerifyLoginTest.java

	/**
	 * uses data from UserInvalid.csv at webApp.data
	 * reruns the test per row of csv file
	 * @param username
	 * @param password
	 */
	@Test(dataProvider = "DataRunner", dataProviderClass = UserInvalid.class)
	public void invalidUserLogin(String username, String password) {
		TestLog.ConsoleLog("username "  + username);
		TestLog.ConsoleLog("password "  + password);

		User user = Data.webApp.user().withUsername(username).withPassword(password);
		TestLog.When("I login with invalid user");
		app.webApp.login.loginError(user);
	}

• We set the dataProvider name to "DataRunner". This is used for all dataProviders.

• The dataProviderClass is set to the csv file name. This refers to the generated class for the csv file

• We pass in the data column as parameters

• We then create a user object based on the user.csv template to pass into the loginError function

• User user = Data.webApp.user().withUsername(username).withPassword(password);
