Support zip files where EOCD's offset to central dir is -1 When zip files contain more than 2**16 entries, the regular EOCD is not sufficient to describe the number of files in the archive, and a Zip64 EOCD needs to be written. When a Zip64 EOCD is written, some zip libraries write -1 for many of the fields in the regular EOCD, including the offset to central dir: From APPNOTE.TXT ยง4.4.1.4 If one of the fields in the end of central directory record is too small to hold required data, the field SHOULD be set to -1 (0xFFFF or 0xFFFFFFFF) and the ZIP64 format record SHOULD be created. Previously FileMap assumed that the regular EOCD contained a valid offset to central dir field. This broke recently when an experimental Android SDK had more than 64k entries in the zip file and -1 for the offset to the central dir. Add support for reading the offset to the central from the Zip64 EOCD. Also add a test case that generates a problematic zip file. PiperOrigin-RevId: 492538213
Robolectric is the industry-standard unit testing framework for Android. With Robolectric, your tests run in a simulated Android environment inside a JVM, without the overhead and flakiness of an emulator. Robolectric tests routinely run 10x faster than those on cold-started emulators.
Robolectric supports running unit tests for 17 different versions of Android, ranging from Jelly Bean (API level 16) to TIRAMISU (API level 33).
Here's an example of a simple test written using Robolectric:
@RunWith(AndroidJUnit4.class) public class MyActivityTest { @Test public void clickingButton_shouldChangeResultsViewText() { Activity activity = Robolectric.setupActivity(MyActivity.class); Button button = (Button) activity.findViewById(R.id.press_me_button); TextView results = (TextView) activity.findViewById(R.id.results_text_view); button.performClick(); assertThat(results.getText().toString(), equalTo("Testing Android Rocks!")); } }
For more information about how to install and use Robolectric on your project, extend its functionality, and join the community of contributors, please visit http://robolectric.org.
If you'd like to start a new project with Robolectric tests you can refer to deckard
(for either maven or gradle) as a guide to setting up both Android and Robolectric on your machine.
testImplementation "junit:junit:4.13.2" testImplementation "org.robolectric:robolectric:4.9"
Robolectric is built using Gradle. Both IntelliJ and Android Studio can import the top-level build.gradle
file and will automatically generate their project files from it.
Those software configurations are recommended and tested.
JAVA_HOME
is correctly point to JDK11, or set the build environment by Gradle CLI option -Dorg.gradle.java.home="YourJdkHomePath"
or by Gradle Properties org.gradle.java.home=YourJdkHomePath
.ninja --version
.cmake --version
.gcc --version
.See Building Robolectric for more details about setting up a build environment for Robolectric.
Robolectric supports running tests against multiple Android API levels. The work it must do to support each API level is slightly different, so its shadows are built separately for each. To build shadows for every API version, run:
./gradlew clean assemble testClasses --parallel
Run tests for all API levels:
The fully tests could consume more than 16G memory(total of physical and virtual memory).
./gradlew test --parallel
Run tests for part of supported API levels, e.g. run tests for API level 26, 27, 28:
./gradlew test --parallel -Drobolectric.enabledSdks=26,27,28
Run compatibility test suites on opening Emulator:
./gradlew connectedCheck
If you would like to live on the bleeding edge, you can try running against a snapshot build. Keep in mind that snapshots represent the most recent changes on master and may contain bugs.
