Robolectric and Android SDK 29

Question

When will Robolectric be compatible with Android SDK 29? Did I upgraded too early by changing targetSdkVersion and compileSdkVersion to 29?

When I run my unit tests I get this huge stacktrace:

java.lang.IllegalArgumentException: API level 29 is not available

Create a robolectric.properties file inside the app/src/test/resources directory with the following line:

sdk=28

This will force Robolectric to use API 28 instead of 29.

Hi, I don't have the "test/resource" directory inside "src", in android studio I choose Project option instead of Android and I have the following folders: androidTest, debug, main, release, test[unitTest]. – Notron Jul 18 '22 at 18:21

With Robolectric 4.3.1 we can use the following alternatives:

Run our test with Java 9 or newer. (We can edit the JRE in the run test configuration)

If we like to run our test with Java 8, we can:

Annotate our test class with @Config in order to emulate a lower SDK (as mentioned by @bencri and @julio-mendoza).

Like this:

@RunWith(AndroidJUnit4::class)
@Config(sdk = Build.VERSION_CODES.P)
class LoginRobolectricTest {
//...
}

Or, as mentioned by @farmerbb, add the robolectric.properties file inside the app/src/test/resources folder with the SDK we like to run, by example:

sdk=28

Adding robolectric.properties worked best. Was easy and worked like a charm. – portfoliobuilder Dec 03 '19 at 18:22

This doesn't work for me. It doesn't seem to be reading the properties file. Any idea why? On Android Studio 4.0 now and it is still failing. – Randy Jun 04 '20 at 17:26
What is the purpose of using `Java 9` with Robolectric? – IgorGanapolsky Sep 09 '21 at 16:00
@IgorGanapolsky in the release https://github.com/robolectric/robolectric/releases/tag/robolectric-4.3.1 says this: Running tests on Android API 29 now strictly requires a Java9 runtime or newer. If you are seeing errors about unsupported Java version when running tests on API 29 via Android Studio; you can use the 'JRE' field in the Run Configuration dialog to configure a newer Java runtime. See https://developer.android.com/studio/run/rundebugconfig for more background. – JuanMoreno Sep 09 '21 at 17:51
Interesting, as of today Robolectric runs on API `30`, but not `31`... – IgorGanapolsky Sep 09 '21 at 18:39
@IgorGanapolsky, yeah, also if you see the Robolectric's CI run against Java 11.0.8 https://github.com/robolectric/robolectric/blob/ca9ddc9b4d0cf4ff8a9f19b0e7505b8a10571621/.github/workflows/tests.yml#L29 – JuanMoreno Sep 09 '21 at 20:10

If anyone is wondering, the solution for me was to annotate my test classes with

@Config(sdk = Build.VERSION_CODES.O_MR1)

The solution for me was to add: `@Config(sdk = [Build.VERSION_CODES.P])` using Roboelectric 4.3. – Julio Mendoza Sep 24 '19 at 13:29

Latest Robolectric 4.3 already supports Android Q (https://github.com/robolectric/robolectric/releases)

Look like I'm missing something then. When I run my unit tests I get an error message "IllegalArgumentException: API level 29 is not available". I updated my post accordingly. – Bencri Jul 01 '19 at 07:15
How do you specify Android Q dependency of the build? – Eugen Martynov Jul 01 '19 at 22:12
My compileSdkVersion and targetSdkVersion are set to 29 – Bencri Jul 02 '19 at 07:21
Can you try using Q instead? – Eugen Martynov Jul 03 '19 at 05:10
I don't really know how to set up the run with Q - I just read release notes. The best would be to create a ticket on the Robolectric GitHub repository. – Eugen Martynov Jul 03 '19 at 05:10
The issue really is, as the link you sent says: Running tests on Android API 29 now strictly requires a Java9 runtime or newer. This can be easily fixed in dev environment. But people might strugle changing CI/CD environments. – Vitor Hugo Schwaab Jan 09 '20 at 13:18
@VitorHugoSchwaab if you use Docker on your CI then it is much easier than dev machine changes – Eugen Martynov Jan 09 '20 at 15:34
