Unresolved reference: junit4: Android ComposeUI testing

I was trying to test the UI I built using jetpack compose in android and added these dependancies to set it up

    androidTestImplementation "androidx.compose.ui:ui-test-junit4:1.1.0"
    debugImplementation "androidx.compose.ui:ui-test-manifest:1.0.5"

for the testing I was just starting to write the following

class LoginActivityComposeTest {
    @get:Rule
    val composeTestRule = createComposeRule()

    @Test
    fun socialPluginsTest() {
        composeTestRule.setContent {
            SocialLogins()
        }
    }
}

The createComposeRule() which I am trying to import was not available. I've tried to manually import from import androidx.compose.ui.test.junit4.createComposeRule But when I try to run the tests after that there is an error showing

Unresolved reference: junit4

Here is the full build.gradle dependancies I am using

compose_version = '1.0.1' retrofit_version = '2.9.0'

    implementation "androidx.core:core-ktx:1.7.0"
    implementation "androidx.compose.ui:ui:$compose_version"
    implementation "androidx.compose.material:material:$compose_version"
    implementation "androidx.compose.ui:ui-tooling-preview:$compose_version"

You might need to add @RunWith(AndroidJUnit4::class) to the top of your test class.

I can't say with 100% accuracy as I'm not sure what else might be causing that in your gradle setup, but I've ran into a similar issue, and that was my solution.
