A Gradle plugin which enables Robolectric tests.
Currently compatible with version 0.13.x of the android gradle plugin.
If you are starting a new app, or want to try this plugin in the simplest possible environment, the easiest way to start is to use deckard-gradle.
deckard-gradle illustrates how to run Robolectric and Espresso tests in IntelliJ, Android Studio or the command-line.
Add the plugin to your buildscript
's dependencies
section:
classpath 'org.robolectric:robolectric-gradle-plugin:0.13.+'
Apply the robolectric
plugin:
apply plugin: 'robolectric'
Add test-only dependencies using the androidTestCompile
configuration:
androidTestCompile 'org.robolectric:robolectric:2.3'
Place your tests in src/test/java
or src/androidTest/java
You can also add per-build type and per-flavor tests by using the same folder naming conventions (e.g., src/testPaid/java
, src/testDebug/java
).
Run your tests by calling gradle clean test
.
robolectric {
// configure the set of classes for JUnit tests
include '**/*Test.class'
exclude '**/espresso/**/*.class'
// configure max heap size of the test JVM
maxHeapSize = '2048m'
// configure whether failing tests should fail the build
ignoreFailures true
// use afterTest to listen to the test execution results
afterTest { descriptor, result ->
println "Executing test for {$descriptor.name} with result: ${result.resultType}"
}
}
In a nutshell, you should be able to import into these IDEs (and continuously sync when you change your build.gradle).
It bears repeating, though: if you see the dreaded Stub!
exception:
!!! JUnit version 3.8 or later expected:
java.lang.RuntimeException: Stub!
at junit.runner.BaseTestRunner.<init>(BaseTestRunner.java:5)
at junit.textui.TestRunner.<init>(TestRunner.java:54)
at junit.textui.TestRunner.<init>(TestRunner.java:48)
at junit.textui.TestRunner.<init>(TestRunner.java:41)
...you will have to hand-edit your dependencies (in the IDE for IntelliJ, or hand-editing your IML file in Studio). See deckard-gradle for details.
