Detox: Detox hangs when running android

In debug mode the bundle is usually loaded from the local server, as the app loads. Is it possible that it is rather big, then? In any case - as the message says, you can try to provide a longer time-out to DetoxTest.runTests() using a custom configuration. Please revisit your implementation of DetoxTest.java and lmk.

@d4vidi thanks, this tip helped me. Here is full DetoxTest.java code which solved com.wix.detox.common.DetoxErrors$DetoxRuntimeException: Waited for the new RN-context for too long! (60 seconds) for me.

import com.wix.detox.Detox;
import com.wix.detox.config.DetoxConfig;

import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;

import androidx.test.ext.junit.runners.AndroidJUnit4;
import androidx.test.rule.ActivityTestRule;

@RunWith(AndroidJUnit4.class)
public class DetoxTest {

    @Rule
    public ActivityTestRule<MainActivity> mActivityRule = new ActivityTestRule<>(MainActivity.class, false, false);

    @Test
    public void runDetoxTests() {
        DetoxConfig detoxConfig = new DetoxConfig();
        detoxConfig.idlePolicyConfig.masterTimeoutSec = 500;
        detoxConfig.idlePolicyConfig.idleResourceTimeoutSec = 500;
        detoxConfig.rnContextLoadTimeoutSec = 500;
        Detox.runTests(mActivityRule, detoxConfig);
    }
}

@barak109 any updates? Something is obviously keeping the app from loading the JS code. Need to find what it is and whether it’s a problem in Detox.

@d4vidi Unfortunately no, we tried for a month to understand the problem there(figure out why the app doesn’t load the JS code) but we didn’t find any solution from our side.

I have the same problem, can not run tests without pressing the reload bundle

Hi guys, We found out a solution, add inside your android first activity that line:

getReactNativeHost().getReactInstanceManager().getDevSupportManager().handleReloadJS();

Hi @barak109 would you mind sharing the file where you used this code? We have the same problem with Android, it just seems to hang.
