System tracing. When you create a new project or add an app module, Android Studio creates the test source sets listed above and includes an example test file in each.
You can see them in the Project window as shown in figure 1. Figure 1. Your project's 1 instrumented tests and 2 local JVM tests are visible in either the Project view left or Android view right.
To create either a local unit test or an instrumented test, you can create a new test for a specific class or method by following these steps:.
Also be sure you specify the test library dependencies in your app module's build. For other optional library dependencies and more information about how to write your tests, see Building local unit tests and Building instrumented unit tests.
So, you can get a build error if both APKs depend on different versions of the same library. If Gradle isn't able to detect this version conflict, your app may behave unexpectedly or crash during runtime.
To learn more, read Fix dependency resolution errors. If your project includes build variants with unique source sets, then you might want corresponding instrumented test source sets.
Creating instrumented tests in source sets that correspond to your build variants helps keep your test code organized and allows you to run only the tests that apply to a given build variant.
Now you can add tests to this new source set by following the steps above to add a new test. When you reach the Choose Destination Directory dialog, select the new variant test source set.
For example, the following table shows how instrumentation test files should reside in source sets that correspond to the app's code source sets.
Just as it does for your app source sets, the Gradle build merges and overrides files from different test source sets.
In this case, the AndroidFooTest. For more information about how source sets are merged, see Configure your build.
Another reason you should use build variants for your app and test source sets is to create hermetic tests through mock dependencies.
That is, you can create a product flavor for your app that contains fake implementations of dependencies such as network requests or device sensor data that is ordinarily flaky , and then add a corresponding mock test source set.
For more information, see the blog post about leveraging product flavors for hermetic testing. One of the reasons Gradle configures this node for you is to make sure that the targetPackage property specifies the correct package name of the app under test.
You can change some of the other settings for this node by either creating another manifest file in the test source set or configuring your module-level build.
By default, all tests run against the debug build type. You can change this to another build type by using the testBuildType property in your module-level build.
For example, if you want to run your tests against your "staging" build type, edit the file as shown in the following snippet.
The Android plugin for Gradle allows you to specify certain options for all or just some of your unit tests.
In the module-level build. If you want to have a module dedicated for instrumented tests and isolate the rest of your code from your tests, you can create a separate test module and configure its build similar to that of a library module.
To create a test module, proceed as follows:. If your app module defines multiple product flavors, you can recreate those flavors in your test module, and, using variant aware dependency management , the test module attempts to test the matching flavor in the target module.
By default, test modules contain and test only a debug variant. However, you can create new build types to match the tested app project. To make the test module test a different build type, and not the debug one, use VariantFilter to disable the debug variant in the test project, as shown below:.
If you want a test module to target only certain flavors or build types of an app, you can use the matchingFallbacks property to target only the variants you want to test.
This also prevents the test module from having to configure those variants for itself. By default, your test runs using Android Studio's default run configuration.
The test coverage tool is available for local unit tests to track the percentage and areas of your app code that your unit tests have covered.
Use the test coverage tool to determine whether you have adequately tested the elements, classes, methods, and lines of code that make up your app.
There are a number of ways to run a unit test, and they are described on the IntelliJ Running with Coverage page. The following procedure shows how to run a unit test inline from the editor:.
The coverage tool window appears. Figure 2 shows the coverage tool window for a calculator unit test that tests for addition, subtraction, multiplication, and division.
Figure 2. See the code coverage percentages for your application. For more information about local unit tests, see Building local unit tests.
When you run a JUnit or instrumented test, the results appear in the Run window. A green bar means all tests succeeded and a red bar means at least one test failed.
Figure 3 shows a successful test run. Figure 3. Test results appear in the Run window. The Run window displays the tests in a tree view on the left, and the results and messages for the current test suite in the output pane on the right.
Use the toolbars, context menus, and status icons to manage the test results, as follows:. If a unit test contains assertEquals failures from comparing two string objects, you can see what the differences are between the two string objects to find out what caused the failures, as follows:.

The more features your app has, the harder it is to test manually. Automated tests help ensure that your app performs correctly before you publish it, while retaining your feature and bug fix velocity.
Generally speaking, a well-tested app has many unit and widget tests, tracked by code coverage , plus enough integration tests to cover all the important use cases.
This advice is based on the fact that there are trade-offs between different kinds of testing, seen below. A unit test tests a single function, method, or class.
The goal of a unit test is to verify the correctness of a unit of logic under a variety of conditions.
External dependencies of the unit under test are generally mocked out. A widget test in other UI frameworks referred to as component test tests a single widget.
Testing a widget involves multiple classes and requires a test environment that provides the appropriate widget lifecycle context.
For example, the Widget being tested should be able to receive and respond to user actions and events, perform layout, and instantiate child widgets.
A widget test is therefore more comprehensive than a unit test. An integration test tests a complete app or a large part of an app.
