PowerMockitoを使ってEnvironmentをMockしてみた

・コード
mockStaticを使うだけなので簡単

import android.os.Environment
import junit.framework.Assert
import org.junit.Before
import org.junit.Test
import org.junit.runner.RunWith
import org.powermock.api.mockito.PowerMockito
import org.powermock.core.classloader.annotations.PrepareForTest
import org.powermock.modules.junit4.PowerMockRunner
import org.mockito.Mockito
import java.io.File


@RunWith(PowerMockRunner::class)
@PrepareForTest(Environment::class)
class EnvironmentTest {

    @Before
    fun setup() {
        PowerMockito.mockStatic(Environment::class.java)
    }

    @Test
    fun testAAA() {
        PowerMockito.`when`(Environment.getExternalStorageState()).thenReturn(Environment.MEDIA_MOUNTED)
        Assert.assertEquals(Environment.getExternalStorageState(), Environment.MEDIA_MOUNTED)

        val file = File("FILE")
        PowerMockito.`when`<File>(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS)).thenReturn(file)
        Assert.assertEquals(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS).absolutePath, file.absolutePath)
    }
}

import android.os.Environment

import junit.framework.Assert

import org.junit.Before

import org.junit.Test

import org.junit.runner.RunWith

import org.powermock.api.mockito.PowerMockito

import org.powermock.core.classloader.annotations.PrepareForTest

import org.powermock.modules.junit4.PowerMockRunner

import org.mockito.Mockito

import java.io.File

@RunWith(PowerMockRunner::class)

@PrepareForTest(Environment::class)

class EnvironmentTest {

@Before

fun setup() {

PowerMockito.mockStatic(Environment::class.java)

}

@Test

fun testAAA() {

PowerMockito.`when`(Environment.getExternalStorageState()).thenReturn(Environment.MEDIA_MOUNTED)

Assert.assertEquals(Environment.getExternalStorageState(), Environment.MEDIA_MOUNTED)

val file = File("FILE")

PowerMockito.`when`<File>(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS)).thenReturn(file)

Assert.assertEquals(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS).absolutePath, file.absolutePath)

}
