Dataproviders and Asserts

Question

When using DataProviders, on TestNG, my test method has asserts that will fail since the data passed in navigates to a different url. Is there a way to work around this, i.e. a way for the data to only be injected to certain/specific asserts?

@DataProvider(name = "VINNumbers")
public String[][] VINNumbers() {
    return new String[][] {
            {"2T1BU4ECC834670"},
            {"1GKS2JKJR543989"},
            {"2FTDF0820A04457"}
    };
}

@Test(dataProvider = "VINNumbers")
public void shouldNavigateToCorrespondingVinEnteredIn(String VIN) {

    driver.get(findYourCarPage.getURL() + VIN);
    Assert.assertTrue(reactSRP.dealerListingMSRPIsDisplayed());
}

The assert test whether or not the page has an MSRP displayed, but not all dataproviders will have an MSRP displayed so it will fail. The only dataprovider that has it is the first array. Is there a way for dataproviders to be called to specific asserts?

Answer 1

In the data provider, pass another string to indicate whether to execute the assert or not. Change your assertTrue to check for that. Something like following:

@DataProvider(name = "VINNumbers")
public String[][] VINNumbers() {
    return new String[][] {
            {"2T1BU4ECC834670", "true" },
            {"1GKS2JKJR543989", "false" },
            {"2FTDF0820A04457", "false "}
    };
}

@Test(dataProvider = "VINNumbers")
public void shouldNavigateToCorrespondingVinEnteredIn(String VIN, String validVIN) {

    driver.get(findYourCarPage.getURL() + VIN);
    Assert.assertTrue("false".equals(validVIN) || reactSRP.dealerListingMSRPIsDisplayed());
}
