Android fragment in isolation

Solution 1:

The error was related to the way I did import the dependencies on Gradle.

Before:

androidTestImplementation("androidx.fragment:fragment-testing:1.1.0-beta01")
implementation("androidx.fragment:fragment-ktx:1.1.0-beta01")
androidTestImplementation("androidx.test:core:1.2.0")
androidTestImplementation("androidx.test:rules:1.2.0")
androidTestImplementation("androidx.test:runner:1.2.0")

After:

debugImplementation("androidx.fragment:fragment-testing:1.1.0-beta01")
debugImplementation("androidx.fragment:fragment-ktx:1.1.0-beta01")
debugImplementation("androidx.test:core:1.2.0")
debugImplementation("androidx.test:rules:1.2.0")
debugImplementation("androidx.test:runner:1.2.0")

Changed from androidTestImplementation to debugImplementation and it solved the issue. Compiling and running, and green test as result.

Solution 2:

Try to configure this way

debugImplementation('androidx.fragment:fragment-testing:1.1.0') {
        // exclude androidx.test:core while fragment_testing depends on 1.1.0
        exclude group: 'androidx.test', module: 'core'
    }

Solution 3:

it works for me

def fragmentx_version = "1.1.0"
implementation "androidx.fragment:fragment:$fragmentx_version"
debugImplementation ("androidx.fragment:fragment-testing:$fragmentx_version"){
     exclude group: 'androidx.test', module: 'core'
}
debugImplementation 'androidx.test:core-ktx:1.2.0'

@Test
fun verifyMap() {
     FragmentScenario.launchInContainer(HomeFragment::class.java)

     onView(withId(R.id.map)).check(matches(isDisplayed()))
}
