Jvm options in android when run gradlew test - android

I have a project that using Robolectric for unit test purpose. This project uses Robolectric 3.0 and need to add -ea and -noverify options in Virtual Machine options.
In Android Studio, I created new JUnit configuration in Run > Edit Configurations... and then set VM Options to -ea -noverify. With this way I success to run my unit test. This is image about my configure, view Here
However, for continuous deployment, I need run unit test with command line. So I use ./gradlew test to run unit test. I also add org.gradle.jvmargs=-ea -noverify to gradle.properties file. Unfortunately, it doesn't work. I can run unit test but I got java.lang.VerifyError and I think that gradle.properties was not load.
So, my question is, how to make gradle.properties load or do you know any way to fix my vm options problem?

It is already answered but this may be an easier solution:
In your application modules' build.gradle file in android closure, add this.
android {
....
testOptions {
unitTests.all {
jvmArgs '-noverify'
}
}
}

I found that we can add this block to app's build.gradle to solve this problem
tasks.whenTaskAdded { theTask ->
def taskName = theTask.name.toString()
if ("testDevDebug".toString().equals(taskName)) {
theTask.jvmArgs('-ea', '-noverify')
}
}
DevDebug is my build variant.

Maybe this
./gradlew -Dorg.gradle.jvmargs="-ea -noverify" test

android getting coverage on local unit tests

I've been trying to get the code coverage for my local unit tests and haven't been successful.
Here's a reference on what I mean by local unit tests.
https://developer.android.com/training/testing/unit-testing/local-unit-tests.html
To run my unit tests, I use the following gradle command.
./gradlew clean testDebugUnitTest
This task will run the unit tests but when I view the jacoco file that gets generated (testDebugUnitTest.ec) in "build/jacoco" folder, it always shows an empty coverage.
I've enabled the coverage in my build.gradle file as follows.
android {
buildTypes {
debug {
testCoverageEnabled true
}
}
}
but that doesn't seem to help. Is there something that I am missing?
Note that if I run the local unit tests through Android Studio, everything works fine. I clicked on my "tests" module and click on "Run tests with coverage".
So, I found out the answer to my own question. Oddly enough, it looks like running "testDebugUnitTest" with the "testCoverageEnabled" flag set is the correct way to do it.
However, since apparently gradle's jacoco version is different than the jacoco version that is running in Android Studio and my CI system (Jenkins), it wasn't able to be viewed due to some backwards compatibility issue in jacoco.
To fix the issue, I set my jacoco version in gradle to the same one in my Android Studio (Intellij) and Jenkins.
jacoco {
toolVersion = '0.7.0.201403182114'
}
I put the code above in my build.gradle file.
I've had to solve the problem myself and I was actually expecting the default gradle plugin will have support for code coverage for local unit tests. Unfortunately, out of the box, there is no support for this, even on android gradle plugin version 3.0.1.
Fortunately, however, there is a simple third-party plugin we can use to generate jacoco test reports: gradle-android-junit-jacoco-plugin
To use it, you need to register this plugin's repository and classpath into your root-level build.gradle. Your build.gradle file might look different, but this is what worked for me:
buildscript {
repositories {
// ... there may be other repositories here
maven {
url "https://plugins.gradle.org/m2/"
}
}
dependencies {
// ... other classpaths here too
classpath "gradle.plugin.com.vanniktech:gradle-android-junit-jacoco-plugin:0.11.0"
}
}
And to generate the report, one can simply do this:
./gradlew jacocoTestReportDebug
The output will be in one of your modules build folder, for example:
your-module/build/reports/coverage/debug/index.html
Note I verified this working on android gradle plugin 3.0.1.
For reference, my source is this answer from Niklas, creator of the plug-in: https://stackoverflow.com/a/33064500/390718

Exclude Gradle #LargeTest

I am trying to run unit test on a separate task from the UI tests that I have within the integration tests in Android Studio, unfortunately I have to use
apply plugin: 'com.android.application'
in the build.gradle file so I cannot add the custom test tasks as far as I can tell. Since the UI tests are tagged as "#Test" and extend InstrumentationTestCase they get run whenever
gradle connectedCheck
is called which is not needed, instead I want one gradle command to run UI tests and one to run unit tests. I figured that I would be able to leverage tagging the UI tests as LargeTests but have not been able to complete a gradle task that can do this. I am not able to use the "test" task in the build.gradle since we are using the com.android.application plugin, and advice?
Thanks
You can do this from command-line without modifying the build.gradle file:
./gradlew cAT -Pandroid.testInstrumentationRunnerArguments.notAnnotation=android.test.suitebuilder.annotation.LargeTest
What ended up working for me is adding the
#LargeTest
using
import android.support.test.filters.LargeTest;
annotation to the tests I needed and then adding the following lines to the build.gradle
if(!project.hasProperty('android.testInstrumentationRunnerArguments.annotation')) {
testInstrumentationRunnerArgument 'notAnnotation', 'android.support.test.filters.LargeTest'
}
this way unless I specify in the command line to run the large tests they will,be ignored. To run the large tests use:
gradle cAT -Pandroid.testInstrumentationRunnerArguments.annotation=android.support.test.filters.LargeTest

Testing multiple build variants simultaneously

I created a Test case (using Espresso 2) for an application with multiple Flavors and I would like to run that Test for all the flavors simultaneously (or at least one after the other). Is that possible? At the moment I am only able to run the test for the current Build Variant selected, so I have to manually change the Build Variant and run the test again, one by one.
Thank you very much.
If you know the names of the gradle tasks that install your tests you can run this from the root of your project in the terminal:
./gradlew install{VariantName1, VariantName2, VariantName3}Test
This assumes you have a module build.gradle file with variants set up according to the guide. So something along these lines:
apply plugin: 'com.android.application'
android {
...
flavorDimensions "myFlavorDimension"
productFlavors {
VariantName1 {
...
}
VariantName2 {
...
}
VariantName3 {
...
}
}
...
}
dependencies {
...
}
You can find these gradle task names either in Android Studio in the Gradle Tab (right side of GUI) under you moduleName->Tasks->install
Or you can find them in the terminal with:
./gradlew tasks | grep install
I'm sure there is some Regex that could grab only the ones of interest programmatically as well, but I'm not a regex buff. If you want to leave a comment with something that would work, I'd be happy to edit and add later.

How to add a new source directory to an Android Studio project?

So ultimately I'm trying to separate my integration tests from the unit tests in an Android Studio project. I've found a few resources on the subject:
http://selimober.com/blog/2014/01/24/separate-unit-and-integration-tests-using-gradle/
https://blog.safaribooksonline.com/2013/08/22/gradle-test-organization/
Separating integration tests from unit tests in Android Studio
All these seem to indicate that the way to go is to create a new sourceSet for the integration tests, and then to create a new test task which builds and runs the tests in that source set. I can't get past the first step of creating a source set which is recognized by Android Studio.
Here's what I have within app/build.gradle, which builds without errors, but does not result in an integrationTest source root I can add classes to:
android{
...
sourceSets{
integrationTest {
java.srcDir('src/integrationTest/java')
}
}
}
My questions are:
Where precisely do I have to add the sourceSets block? In build.gradle? in app/build.gradle? In app/build.gradle inside the android block?
Once I've added my source set in he right place using the correct syntax, is this sufficient for Android Studio to detect and present it in the UI along side the main and test sources, or are there additional steps?
edit:
I've attempted to follow the instructions in marius' answer, but integrationTest isn't showing up in my build variants. Here's what I'm seeing:
This is enough:
android{
...
productFlavors{
integrationTest {
}
}
}
Regarding your 1st question: The productFlavors block should be in your app/build.gradle, inside android block.
Regarding your 2nd question: Once you add this to your build.gradle file, you also need to create your folders /src/integrationTest and /src/integrationTest/java . Once that is done, sync your gradle files and choose your new Build Variant from the Build Variant window, in order for the IDE to detect it as the active source folder.

How to get code coverage using Android Studio?

I am developing apps using Android Studio.
I was able to run the test code.
But, I do not know how to get code coverage in android studio.
I have already seen the following links.
Android Gradle Code Coverage
But I can't wait for update to v0.6 supporting emma.
Project configuration is as follows.
Main code
MyProject/AppName/src/main/java/mypackage/MyClass.java
Test code
MyProject/AppName/src/instrumentTest/java/mypackage/test/MyClassTest.java
Project configuration
MyProject
├─build.gradle
└─AppName
├─build.gradle
└─src
├─main
│ ├─java
│ │ └─mypackage
│ │ └─MyClass.java
│ ├─res
│ └─AndroidManifest.xml
└─instrumentTest
└─java
└─mypackage
└─test
└─MyClassTest.java
With the new Android Studio 1.2, you are able to run your unit tests and see the coverage all within the IDE.
First, you'll need to get your unit tests running in the IDE. (if you already can, then skip this step)
This guide and demo will help you.
Secondly, you'll need to create a JUnit Run configuration
Inside this configuraiton, you'll be able to choose
Test Kind: "All in Package"
Package: [the package where your tests reside, eg: "com.myapp.tests"]
Search for tests: Across Module Dependencies (could be diff for your
setup)
VM -options: -ea
Working Directory: [your project's directory]
Use classpath of mod: [select your module]
If you have any issue creating your JUnit Run Configuration, you should visit this guide for help.
Lastly, in the latest Android Studio, you should be able to run your JUnit-Run Configuration by clicking on the 'Run with Coverage' button.
In Android Studio 2.1.3 the is label Run Unit tests with Coverage where Unit test is the name of your test configuration as shown in the following screenshot:
There are so much answers showing how to apply jacoco plugin to Android studio project, which is outdated, and wasted me so much time to figure out the solution for recently Android studio(My Android Studio is version 2.1.2).
Jacoco plugin is built in for Android Studio gradle, what you need to do is just enable it like following:
buildTypes {
...
debug {
testCoverageEnabled true
}
}
After you do above, run unit test task
./gradlew testDebugUnitTest
Then create coverage files:
./gradlew createDebugCoverageReport
Coverage files will be created under <module>/build/reports/coverage/debug folder,include index.html, which you can open it with browser, and report.xml which you can use to get a report by jenkins jacoco plugin or other continues integration tools.
For those who got 0% coverage with jenkins jacoco plugin, be sure to use the right version.
quote from their site:
Unfortunately JaCoCo 0.7.5 breaks compatibility to previous binary
formats of the jacoco.exec files. The JaCoCo plugin up to version
1.0.19 is based on JaCoCo 0.7.4, thus you cannot use this version with projects which already use JaCoCo 0.7.5 or newer. JaCoCo plugin
starting with version 2.0.0 uses JaCoCo 0.7.5 and thus requires also
this version to be used in your projects. Please stick to JaCoCo
plugin 1.0.19 or lower if you still use JaCoCo 0.7.4 or lower
If you want to get your test coverage (for instrumented tests - When the 'Run the app with Coverage' is not enabled):
Put this into your top-level build.gradle:
buildscript{
ext.jacocoVersion = '0.8.2'
...
dependencies {
classpath "org.jacoco:org.jacoco.core:$jacocoVersion"
}
}
Into your app-level build.gradle:
...
apply plugin: 'jacoco'
jacoco {
toolVersion = "$jacocoVersion"
}
tasks.withType(Test) {
jacoco.includeNoLocationClasses = true
}
task jacocoTestReport(type: JacocoReport, dependsOn: ['testDebugUnitTest', 'createDebugCoverageReport']) {
reports {
xml.enabled = true
html.enabled = true
}
def fileFilter = [
'**/R.class', '**/R$*.class', '**/BuildConfig.*', '**/Manifest*.*', '**/*Test*.*', 'android/**/*.*', '**/*$[0-9].*'
]
def debugTree = fileTree(dir: "$project.buildDir/tmp/kotlin-classes/debug", excludes: fileFilter)
def mainSrc = "$project.projectDir/src/main/kotlin"
sourceDirectories = files([mainSrc])
classDirectories = files([debugTree])
executionData = fileTree(dir: project.buildDir, includes: [
'jacoco/testDebugUnitTest.exec', 'outputs/code_coverage/debugAndroidTest/connected/**/*.ec'
])
}
android {
...
buildTypes {
debug {
testCoverageEnabled true
}
}
Then you should write your test, and tests have to passed. If you are sure, your tests passed, write that code into the terminal:
gradlew connectedCheck
It will run your tests.
If you did everything right, you should get a report file in
app -> build -> reports -> coverage.
You have to open the index.html file. (Right click on the file -> Open in Browser -> select a browser)
You should get something similar to this.
It's working in my project. Maybe there is a better and easier solution.
If I forgot something to write down here, pls write comment.
Enable testCoverage in your module build.gradle file
buildTypes {
debug {
testCoverageEnabled true
}
}
and then
Right click on the test -> java package and select Run Tests in Java with Coverage to run all tests with code coverage or right click on the particular test class and click Run SampleTest with Coverage
We use maven to build our app and cobertura for code coverage reporting
both are really easy to integrate
android maven integration:

Maven + Cobertura Code Coverage Example:
http://www.mkyong.com/qa/maven-cobertura-code-coverage-example/
I don't think you can see visual code coverage report inside Android Studio. But you could try Jacoco. You will need to integrate it in your build.gradle file. You can find the similar question & solution here
Have you tried using the Jacoco plugin for getting code coverage for your project? It is a good plugin giving you coverage based on your package or individual classes. I am not sure how you configure Jacoco to use with Gradle since i use Maven. Check the link: and see if it helps you
Android studio gradle has inbuilt Jacoco plugin which you can use to find code coverage. I have written as article to step by step configure jaococo to find code coverage for Espresso test case but you can use it for Robotium as well. check this out.
http://qaautomated.blogspot.in/2016/03/how-to-find-code-coverage-with-jacoco.html
You can just right click on the package you are curious about and select Run 'Tests in "package" with coverage'
