Introduction to Testing Android Apps
ANDROID TESTING
-
There are two types of tests for unit testing in Android, both
of which use the JUnit testing framework
-
-
JVM tests for testing your Java code in the project.
-
Execute quickly (milliseconds) on your machines JVM
-
Located in the test source set (project > app > src > test)
Instrumented tests for testing code that uses the Android SDK
-
May take longer (seconds) on an emulator or Android device
directly
-
Located in the androidTest source set (project > app > src >
androidTest)
ANDROID TESTING
ANDROID TESTING
-
Shortcut to the “create a test” wizard: ctrl+shift+T (or
command+shift+T) when your cursor is inside of the class you
want to create a test for.
-
To run a test
-
Right click on the test class, choose “Run” OR Click ▶ next to
the test name to run
For instrumented tests, connect a device first (these tests
require a device - virtual or physical).
ANDROID TESTING
-
-
JVM Tests
-
Test the Java code in your project
-
Follow the same paradigms as the JUnit tests previously discussed
-
Naming conventions for classes and methods
-
Use of assert statements
Instrumented tests
-
Test code in your project which uses the Android SDK (e.g. Activity,
TextView, etc)
-
ActivityScenario provides APIs to start and drive an Activitys lifecycle
state for testing!
-
Espresso for Android UI testing
-
State expectations
-
Interactions
-
assertions
ACTIVITY LIFE CYCLE
-
As a user navigates through, out of, and back to your app, the
Activity instances in your app transition through different
states in their lifecycle.
-
The Activity class provides a number of callbacks that let the
activity know when a state changes or that the system is
creating, stopping, or resuming an activity or destroying the
process the activity resides in.
