I just created a new android application with Kotlin Support.
When I've tried to run the default instrumented tests it does not run and shows me this message:
Class not found: "oussaki.com.pos.ExampleInstrumentedTest"Empty test suite.
This the Instrumented test class that I'm trying to run:
#RunWith(AndroidJUnit4::class)
class ExampleInstrumentedTest {
#Test
fun useAppContext() {
// Context of the app under test.
val appContext = InstrumentationRegistry.getTargetContext()
assertEquals("oussaki.com.pos", appContext.packageName)
}
}
This is a known issue: https://issuetracker.google.com/issues/38452937 which hopefully will be fixed in the next release.
For the time being you can manually go to 'Edit Configurations' and add the configuration for the specific class/method you want to run under 'Android Instrumented Tests'.
You could also try the latest canary build: https://developer.android.com/studio/preview/index.html but personally I've had trouble getting it to work with my project.

So with the release of Android Studio Dolphin & Beta of Electric Eel, I wanted to try the instrumentation tests in gradle. I do however want to exclude some of the tests being run, in order to be able to run specific test suites one at a time.
So here is what I configured so far:
android {
testOptions {
managedDevices {
devices {
pixel2api30 (com.android.build.api.dsl.ManagedVirtualDevice) {
device = "Pixel 2"
apiLevel = 30
systemImageSource = "aosp-atd"
}
}
}
}
}
I know I can run my entire suite using
./gradlew device-nameBuildVariantAndroidTest
In my case that would be
./gradlew pixel2api30gaeDebugAndroidTest
gaeDebug being my build variant. This command is being run in my project root.
If I want to run the tests in the tests/large folder for example
How would I go about doing that? Thanks.
For this you could use 2 different approaches:
Create and run test suites.
For example, for each of these folders, create a TestSuite and define Test classes. For example:
#RunWith(Suite.class)
#Suite.SuiteClasses({
ExampleLargeTest.class,
ExampleTwoLargeTest.class,
ExampleThreeLargeTest.class
})
public class LargeTestsSuite {
}
This suite can be run using following command
./gradlew pixel2api30gaeDebugAndroidTest - Pandroid.testInstrumentationRunnerArguments.class=path.to.your.suite.class
Use Test Categories
Annotate your Test classes like this:
#Category("Large")
public class ExampleLargeTest { ... }
And then you could execute the following command for running all tests with same category:
./gradlew pixel2api30gaeDebugAndroidTest -PtestCategory=Large
Hopefully one of these two approaches will suite you.
Hi I am trying to run a basic JUnit test in Android Studio. When I click run it is terminated every time before getting results. I never get pass or fail and the system does not try any other test cases.
Here are the pictures. I would like to know why it isn't working so I can keep practicing.
You can try a couple of things
Decorate your test class with #SmallTest
// #RunWith is required only if you use a mix of JUnit3 and JUnit4.
#RunWith(AndroidJUnit4::class)
#SmallTest
class ExampleInstrumentedTest {
}
Try to run your test from the command line:
./gradlew connectedAndroidTest
I have written multiple test methods in a single android instrumented test class, when I am trying to run a single test method it will run all methods exists in that class.
I want to run only one.
Earlier I was able to run all, but somehow configuration settings have been changed
class HistoryTest{
#Test
fun openHistoryTest{
}
#Test
fun closeHistoryTest{
}
#Test
fun editHistoryTest{
}
}
I want to run a specific single test method say openHistoryTest.
Currently getting an error - the command line is too long shorten the command line for test "testname"
I updated Android Studio to canary and can run the whole class or a single method as instrumental test. Currently using AS 3.6 Canary 12.
Still doesn't work on Android Studio 3.5. I can't run each method as an
instrumental test, only the whole class.
I gave a try to Android Test Orchestrator and it doesn't see any tests if Application class were changed. Pretty easy to reproduce.
In Android Studio 3 preview Beta 6 create simple project with wizard
Create custom runner like:
class CustomTestRunner : AndroidJUnitRunner() {
override fun newApplication(cl: ClassLoader?, className: String?, context: Context?): Application {
return super.newApplication(cl, TestApplicationClass::class.simpleName, context)
}
}
Replace instrumentation runner with new one
No test found after running instrumented tests
Any ideas? Looks like the Orchestrator depends on application class name from manifest.
I use this configuration to use special Dagger dependencies for tests.
I had the similar issue, with a custom test runner. Make sure that your TestApplicationClass does not crash at runtime. If the custom runner crashes then orchestrator will not be able to get information about the tests and will return the message:
No tests found. This usually means that your test classes are not in the form that your test runner expects (e.g. don't inherit from TestCase or lack #Test annotations).
That is what happened to me in my custom runner.
Good luck!
Do anyone know how to integrate robolectric into android studio?
How to write sample test?
How to launch it?
I am working with android studio not to long, and I am too bad with gradle.
Searching the net didn't give me a result - I even could not launch official demo - https://github.com/robolectric/robolectric-samples . My android studio do not saw the test class.
Please give me simpliest step by step gide, thanks
Since robolectric runs in a JVM (i.e. not on a device or emulator), it is just a library and adding the test runner is all that's needed.
Make sure that the android SDK is later in the classpath than robolectric or junit - otherwise you'll get the stubbed methods from the android SDK.
#RunWith(RobolectricTestRunner.class)
public class MyActivityTest {
#Test
public void shouldHaveApplicationName() throws Exception {
String appName = new MyActivity().getResources().getString(R.string.app_name);
assertThat(appName, equalTo("MyActivity"));
}
}
See http://robolectric.org/quick-start/
