Control App

Overview

This is how one BELLATRIX test class looks like.

@ExecutionApp(appPath = "path/to/TestApp.app.zip",
        iOSVersion = "14.2",
        deviceName = "iPhone 8",
        lifecycle = Lifecycle.REUSE_IF_STARTED)
public class BellatrixAppBehaviourTests extends IOSTest {
    @Test
    public void buttonClicked_When_CallClickMethod() {
        var button = app().create().byName(Button.class, "ComputeSumButton");

        button.click();
    }

    @Test
    public void returnsTrue_When_CallButtonIsPresent() {
        var button = app().create().byName(Button.class, "ComputeSumButton");

        Assert.assertTrue(button.isPresent()); 
    }
}

Explanations

@ExecutionApp(appPath = "path/to/TestApp.app.zip",
        iOSVersion = "14.2",
        deviceName = "iPhone 8",
        lifecycle = Lifecycle.REUSE_IF_STARTED)

This is the attribute for automatic start/control of iOS apps by BELLATRIX. If you have to do it manually properly, you will need thousands of lines of code. appPath – sets the path where your app file is. lifecycle – uses the Lifecycle enum to control when the app is started and stopped. This can drastically increase or decrease the tests execution time, depending on your needs.
However you need to be careful because in case of tests failures the app may need to be restarted. Available options:

• RESTART_EVERY_TIME- for each test a separate WebDriver instance is created and the previous app instance is
• RESTART_ON_FAIL- the app is only restarted if the previous test failed. Alternatively, if the previous test’s app was different.
• REUSE_IF_STARTED- the app is only restarted if the previous test’s app was different. In all other cases, the app is reused if possible.

Note: However, use this option with caution since in some rare cases if you have not properly setup your tests you may need to restart the app if the test fails otherwise all other tests may fail too.

There are even more things you can do with this attribute, but we look into them in the next sections.

public class BellatrixAppBehaviourTests extends IOSTest

All iOS BELLATRIX test classes should inherit from the IOSTest base class. This way you can use all built-in BELLATRIX tools and functionalities.

@ExecutionApp(appPath = "path/to/TestApp.app.zip",
        iOSVersion = "14.2",
        deviceName = "iPhone 8",
        lifecycle = Lifecycle.REUSE_IF_STARTED)
public class BellatrixAppBehaviourTests extends IOSTest

If you place attribute over the class all tests inherit the behaviour. It is possible to place it over each test and this way it overrides the class behaviour only for this particular test.

@Test
public void buttonClicked_When_CallClickMethod()

All TestNG/JUnit tests should be marked with the Test annotation.

var button = app().create().byName(Button.class, "ComputeSumButton");

Use the element creation service to create an instance of the button. There are much more details about this process in the next sections.
