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

回答1:
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.
回答2:
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:
- Annotated 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 @farmerbb, add the robolectric.properties file inside the
app/src/test/resourcesfolder with the SDK we like to run, by example:
sdk=28
回答3:
If anyone is wondering, the solution for me was to annotate my test classes with
@Config(sdk = Build.VERSION_CODES.O_MR1)
回答4:
Latest Robolectric 4.3 already supports Android Q (https://github.com/robolectric/robolectric/releases)
