Data provider documentation is not self contained

[csvtuda]

It's currently impossible to follow the data provider tutorial in the documentation because the examples are not self contained. They mention page objects which have never been defined before:

@TestFeature(
        name = "Calls form",
        description = "Create call form"
)
public class CallsTest extends TestContext {
    @Test(testName = "CallsTest", description = "Calls Test")
    public void testCalls() {
        //Navigate to calls page
        navigator.goToRootPage(); // what is navigator?
        topNavbar.openMobileMenu(); // what is topNavbar?
        topNavbar.clickMobileCallsMenu();
        callsPage.clickCallsModuleButton(); // what is callsPage?
        topBarCallsMenu.clickLogCallLink();
        // Fill call form
        createCallForm.fillSubjectField("Call subject"); // what is createCallForm?
        createCallForm.fillDurationField();
        createCallForm.fillDescriptionField("Call description");
        createCallPage.clickSaveButton();
        //Navigate to Home page
        topNavbar.openMobileMenu();
        topNavbar.clickHomeMenuFromNotHomePage();
    }
}

This has lead to quite a lot of confusion for newcomers and should probably be changed such that either:

• the page objects are defined as well within the data provider documentation
• no page objects occur within the data provider documentation
