Gradle android, how to exclude a single unit test - android

I have an android project with unit and integration tests in the same folder. If I run ./gradlew test all of them are run, but I just need to exclude the cucumber tests from running, at the moment I just need to actually exclude to run the class with the annotation #RunWith(Cucumber.class).
Any suggestions?

The usual way of adding a test closure like below does not work for some reason with gradle android plugin:
test {
exclude 'com/example/MyTest.*'
}
Instead I have found the following option. Use the #Ignore annotation on your test(s). You can also conditionally ignore the test (e.g. based on a system property like RUN_AUTOMATION_TEST=false) using this answer
If you are using spock rather than junit then use something like this:
#IgnoreIf( {System.getProperty('RUN_AUTOMATION_TESTS') == null} )
public class MainScreenSpec extends BaseUiAutomationSpec {
}

AndroidThreeTen not working in unit test without robolectric?

I'm having trouble creating a unit test without needing robolectric. I am using AndroidThreeTen.init(this) in my code and when I run my test if I disable robolectric I get an error:
org.threeten.bp.zone.ZoneRulesException: No time-zone data files registered
and if I leave it enabled I get this:
[Robolectric] com.mycomp.,yapp.utilities.log.LogTest.on Calling function w it returns an Int: sdk=28; resources=BINARY
I have tried using testImplementation ‘com.jakewharton.threetenabp:threetenabp:1.1.0’
made no difference. I have AndroidThreeTen.init(this) called in my application and testApplication. any ideas?
this is my test
#Test
fun `on Calling function i it returns an Int`() {
assertThat("Returned class is not an Int", Log.i("Test", "Test"), isA(Int::class.java))
assertThat("Returned Int is not 0", Log.i("Test", "Test"), `is`(0))
}
Or do I have to use robolectric because of this?
(Side note: Log is not the util.log from android but my own class) (edited)
JVM unit tests don't run on Android runtime. Instead of ThreeTenABP, you can just use ThreeTenBP directly to get the same API initialised for a regular JVM.
In my project build.gradle I use a setup like:
implementation "com.jakewharton.threetenabp:threetenabp:${threetenabpVersion}"
testImplementation("org.threeten:threetenbp:${threetenbpVersion}") {
exclude module: "com.jakewharton.threetenabp:threetenabp:${threetenabpVersion}"
}
where
threetenabpVersion = '1.2.0'
threetenbpVersion = '1.3.8'
This uses ThreeTenBP via ThreeTenABP normally, but in unit test configuration it adds TreeTenBP directly as a dependency, with its init code. Cannot remember exactly why I put in the exclude rule; it's been like that for a few years already.
For some reason #laalto solution didn't work for me. Here's what worked instead:
dependencies {
...
implementation "com.jakewharton.threetenabp:threetenabp:$threetenabp_version"
testImplementation "org.threeten:threetenbp:$threetenbp_version"
}
configurations.testImplementation {
exclude group: 'com.jakewharton.threetenabp'
}

Method setUp in android.test.AndroidTestCase not mocked

I'm trying to come to terms with the new unit test feature of Android Studio.
I've followed the instructions on http://tools.android.com/tech-docs/unit-testing-support. The description there explicitly mentions the 'Method ... not mocked' error and suggests to put the following into the build.gradle:
android {
// ...
testOptions {
unitTests.returnDefaultValues = true
}
}
This works in so far as the tests run when started from the command line with
gradlew test --continue
but not when I run the test class from Android Studio with rightclick -> run. This way, I get the same error again:
java.lang.RuntimeException: Method setUp in android.test.AndroidTestCase not mocked. See https://sites.google.com/a/android.com/tools/tech-docs/unit-testing-support for details.

Any ideas on how to solve this?
EDIT: The content of the test class doesn't really matter because the setUp of the test fails, I tried with the most simple class:
public class ContactFormToolTest extends AndroidTestCase {
public void testSOmething(){
assertEquals(false, true);
}
}
Also tried overriding setUp, makes no difference.
From: https://sites.google.com/a/android.com/tools/tech-docs/unit-testing-support#TOC-Method-...-not-mocked.-
The android.jar file that is used to run unit tests does not contain
any actual code - that is provided by the Android system image on real
devices. Instead, all methods throw exceptions (by default). This is
to make sure your unit tests only test your code and do not depend on
any particular behaviour of the Android platform (that you have not
explicitly mocked e.g. using Mockito). If that proves problematic, you
can add the snippet below to your build.gradle to change this
behavior:
android {
// ...
testOptions {
unitTests.returnDefaultValues = true
}
}
The new Unit Tests feature in Android Studio fakes the entire Android SDK so that you can run fast, Java-only tests, without needing to install your application on an Android device (this is similar to Robolectric). The general idea is that you mock all the responses from the Android SDK calls.
AndroidTestCase is used to run a test with the real Android SDK.
So, your issue is that you are trying to run an AndroidTestCase that depends on the Android SDK, but your test runner is launching the Unit Tests environment, which uses a fake Android SDK instead of a real one.
You need to choose one approach. If you want a pure unit test, then you probably should use a JUnit 4 test class instead of an AndroidTestCase. More instructions here:
https://developer.android.com/training/testing/unit-testing/local-unit-tests.html#build
As of SDK version 24, AndroidTestCase is deprecated
This class was deprecated in API level 24.
Use InstrumentationRegistry instead. New tests should be written using
the Android Testing Support Library.
You are supposed to use the Espresso framework for UI testing. There is a tutorial.

Add New Dependency Configuration That is Used For a Specific Task

I'm trying to setup an Android project, we have certain kind of tests (Tests A) that run differently from other tests (Tests B) that require their own dependencies that can't be included when Tests B run.
I'm trying to add a new configuration that extends androidTestCompile with this code in my build.gradle file:
configurations {
myTestCompile.extendsFrom('androidTestCompile');
}
As per http://chimera.labs.oreilly.com/books/1234000001741/ch04.html#DEPENDENCY-CONFIGURATIONS This doesn't work, it gives me an error 'method not found extendsFrom()'.
I then also don't know how to use certain configurations for a task.
Any help would be appreciated, cheers.
You have to declare the configuration first.
configurations {
myTestCompile
myTestCompile.extendsFrom androidTestCompile
}
Edit
You can then declare a test task that used that configuration.
task testB(type: Test) {
classpath = configurations.myTestCompile
}

Running a specific instrumentation unit test with Gradle

Is there a way to run a specific Android instrumentation unit test using Gradle? I've tried
gradle -Dtest.single=UnitTestName connectedInstrumentTest
but it seems to run all the tests in the package.
Using test.single appears to be deprecated. The new correct way to do this is
./gradlew :<module>:test --tests <pattern>
where <pattern> could be something like:
com.example.MyTest to run all test methods in com.example.MyTest
*MyTest to match every method in every class whose name ends with MyTest
*.MyTest.myMethod to run a specific test method in class MyTest in any package
If you have a multi-project build, make sure to give the module path before the test task; otherwise you'll get a misleading error message when it searches for your test pattern in every subproject.
None of this is documented on the Gradle site anywhere I could find it.
This works if you're using an instrumentationTestRunner:
./gradlew test -Pandroid.testInstrumentationRunnerArguments.class=<pkg>.YourClassName
Using gradle 2.10 and android gradle plugin 2.0.0-beta2.
Since you know what test(s) you want to run, you probably know which module / flavor to use too. You can help Gradle out by specifying the exact module and Gradle task. So if your test is in the app module and you want to test the debug flavor:
./gradlew app:connectedDebugAndroidTest -Pandroid.testInstrumentationRunnerArguments.class=<pkg>.YourClassName
You can get even more fancy with the tests_regex argument instead:
./gradlew app:connectedDebugAndroidTest -Pandroid.testInstrumentationRunnerArguments.tests_regex=PartialClassName*
./gradlew app:connectedDebugAndroidTest -Pandroid.testInstrumentationRunnerArguments.tests_regex=partialMethodName*
The pattern is -D<testTaskName>.single=<TestClass> so in your example it should be:
gradle -DconnectedInstrumentTest.single=UnitTestName connectedInstrumentTest
NOTE: This answer is outdated. You should use the --tests switch in the latest versions of Gradle. (see other answers for an explanation)
Since Android gradle plugin 1.1.0-rc1, one can run single test class using --tests flag by executing:
./gradlew app:testDebug --tests=com.example.MyTest
See http://tools.android.com/tech-docs/unit-testing-support#TOC-Running-from-Gradle
You gotta check this out.
https://github.com/JCAndKSolutions/android-unit-test
I made an issue in this github repository, and this guy solved my problem and upload to maven, so in my build.gradle file I use this plugin.
Instructions are written in his repository. you can easily follow it.
After using this android-unit-test plugin, I can use like
../gradlew -Dtest.single=SomeTest test
or
../gradlew -Dtest.single=SomeTest clean check
Now it's working and I could only run the specific tests I want to
You should not forget to specify a build variant name after test property declaration like
-Dtest<buildVariantName>=<yourTestName>.
Like if you have a debug build type which gives you debug variant after compilation, then if you want to run a test only for this build variant you should declare a command like this:
./gradlew -DtestDebug=UnitTestName testDebug
Erdi's answer didn't work for me but I have a single parent for all my test classes so I was able to do this:
public abstract class BaseEspressoTest<T extends Activity> extends ActivityInstrumentationTestCase2<T> {
//...
#Override
protected void runTest() throws Throwable {
if(getClass().getSimpleName().equals("MyTestClassName")) {
super.runTest();
}
}
//...
}
This executes only MyTestClassName. We can extend it further to execute only specific test method (or methods):
public abstract class BaseEspressoTest<T extends Activity> extends ActivityInstrumentationTestCase2<T> {
//...
#Override
protected void runTest() throws Throwable {
if("MyTestClassName".equals(getClass().getSimpleName())
&& "testMethodName".equals(getName())) {
super.runTest();
}
}
//...
}
the Gradle command does not work for me.
I used below mentioened adb command.
for this you need to build your apk first.
adb shell am instrument -w -r -e package -e debug false .debug.test/android.support.test.runner.AndroidJUnitRunner

Can I use Robolectric to unit test static library jars?

I'm trying to test a method in a jar library, and was hoping to use Robolectric to do my unit testing, rather than running the tests in the Android emulator. I'm running into a problem though, where Robolectric needs an androidmanifest.xml file that doesn't exist, since I'm building a library...
Is there any way to run Robolectric tests without an app?
Here's what my test case and code under test look like:
public class ObjectUnderTest {
methodUnderTest(View v) {
...
}
}
#RunWith(RobolectricTestRunner.class)
public class Tests {
#Test
public void methodUnderTest_Test() {
...
}
}
When I run the test suite I get a FileNotFoundException from Robolectric looking for androidmanifest.xml. I've tried using the JUnit4 test runner instead, but then I get the "Stub!" exception when I create a View for the argument to methodUnderTest().
Is there a way to do this besides creating a stub application just for the unit tests? Thanks!
It depends which Robolectric you're using.
If you use 2.0 you could try to annotate your test class with #Config(manifest=Config.NONE).
If you use 1.x I think it's doable but will require more effort:
You should folder create structure similar to Android project and create dummy AndroidManiifest.xml inside
You should extend RobolectricTestRunner and pass through constructor path to this fake Android project
