Common Components

Learn how to use BELLATRIX common Android components.

Example

[Test]
public void CommonActionsWithAndroidControls()
{
    var button = App.Components.CreateByIdContaining<Button>("button");

    button.Click();

    var radioButton = App.Components.CreateByIdContaining<RadioButton>("radio2");

    Assert.AreEqual(false, radioButton.IsDisabled);

    var checkBox = App.Components.CreateByIdContaining<CheckBox>("check1");

    checkBox.Check();

    Assert.IsTrue(checkBox.IsChecked);

    checkBox.Uncheck();

    Assert.IsFalse(checkBox.IsChecked);

    var comboBox = App.Components.CreateByIdContaining<ComboBox>("spinner1");

    comboBox.SelectByText("Jupiter");

    Assert.AreEqual("Jupiter", comboBox.GetText());

    var label = App.Components.CreateByText<Label>("textColorPrimary");

    Assert.IsTrue(label.IsPresent);

    var password = App.Components.CreateByDescription<Password>("passwordBox");

    password.SetPassword("topsecret");

    var textField = App.Components.CreateByIdContaining<TextField>("edit");

    textField.SetText("BELLATRIX");

    Assert.AreEqual("BELLATRIX", textField.GetText());

    radioButton.Click();

    Assert.IsTrue(radioButton.IsChecked);

    App.AppService.StartActivity(Constants.AndroidNativeAppAppExamplePackage, ".view.SeekBar1");
    var seekBar = App.Components.CreateByClass<SeekBar>("android.widget.SeekBar");

    seekBar.Set(9);

    seekBar.ToExists().WaitToBe();
}

Explanations

As mentioned before BELLATRIX exposes 18+ Android controls. All of them implement Proxy design pattern which means that they are not located immediately when they are created. Another benefit is that each of them includes only the actions that you should be able to do with the specific control and nothing more. For example, you cannot type into a button. Moreover, this way all of the actions has meaningful names- Type not SendKeys as in vanilla WebDriver.

var button = App.Components.CreateByName<Button>("E Button");

Create methods accept a generic parameter the type of the Android control. Then only the methods for this specific control are accessible. Here we tell BELLATRIX to find your element by ID containing the value ‘button’.

button.Click();

Clicks the button. At this moment BELLATRIX locates the component.

var radioButton = App.Components.CreateByIdContaining<RadioButton>("radio2");

Locating the radio button control using ID containing the value ‘radio2’.

Assert.AreEqual(false, radioButton.IsDisabled);

Most Android controls have properties such as checking whether the radio button is enabled or not.

var checkBox = App.Components.CreateByIdContaining<CheckBox>("check1");
checkBox.Check();

Checking and unchecking the CheckBox with id = ‘check1’

Assert.IsTrue(checkBox.IsChecked);

Asserting whether the check was successful.

var comboBox = App.Components.CreateByIdContaining<ComboBox>("spinner1");
comboBox.SelectByText("Jupiter");

Select a value in ComboBox but text.

Assert.AreEqual("Jupiter", comboBox.GetText());

Get the current ComboBox text through GetText method.

var seekBar = App.Components.CreateByClass<SeekBar>("android.widget.SeekBar");
seekBar.Set(9);

Moves the SeekBar.

seekBar.ToExists().WaitToBe();

Wait for the element to exists.

var label = App.Components.CreateByText<Label>("textColorPrimary");
Assert.IsTrue(label.IsPresent);

See if the element is present or not using the IsPresent property.

var password = App.Components.CreateByDescription<Password>("passwordBox");
password.SetPassword("topsecret");
var textField = App.Components.CreateByIdContaining<TextField>("edit");
textField.SetText("Bellatrix");

Instead of using the non-meaningful method SendKeys, BELLATRIX gives you more readable tests through proper methods and properties names. In this case, we set the text in the password field using the SetPassword method and SetText for regular text fields.

var radioButton = App.Components.CreateByIdContaining<RadioButton>("radio2");
radioButton.Click();
 Assert.IsTrue(radioButton.IsChecked);

Select the radio button.
