How can I test ViewModels in AndroidX?

You can test ViewModels in AndroidX using the AndroidX Test library. It provides tools to create unit tests for your ViewModels.

What dependencies do I need to add for testing?

You'll need to add dependencies like 'androidx.test.ext:junit' and 'androidx.lifecycle:lifecycle-viewmodel-ktx' in your build.gradle file.

Can you show me a simple test example?

Sure! Here's a basic example:

class MyViewModelTest {
    private lateinit var viewModel: MyViewModel

    @Before
    fun setUp() {
        viewModel = MyViewModel()
    }

    @Test
    fun testSomeFunction() {
        // Arrange
        val expected = ...

        // Act
        viewModel.someFunction()

        // Assert
        assertEquals(expected, viewModel.someLiveData.value)
    }
}
