##配置 1.修改测试文件夹的目录 Android Studio如何修改单元测试的目录
android DSL jar包位置 C:\Users\ {computer username}\ .gradle\caches\modules-2\files-2.1\com.android.tools.build\gradle2円.1.0\bcae59215a7b71367ece66de0bfaff6441102aea
android {
sourceSets {
test.root 'src/tests/javaTest'
test.java.srcDirs 'src/tests/javaTest/java'
androidTest.root 'src/tests/androidTest'
androidTest.java.srcDirs 'src/tests/androidTest/java'
}
}
##junit text 1.junit库,mockito库
##espresso 依赖库
androidTestCompile ('com.android.support.test.espresso:espresso-core:2.2.2'){
exclude module: 'support-annotations'
}
defaultConfig {
//需要加上,不然会报错
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
@RunWith(AndroidJUnit4.class)
@LargeTest
public class MainActivityTest {
@Rule
public ActivityTestRule<MainActivity> mActivityRule = new ActivityTestRule(MainActivity.class);
@Test
public void testSample() {
onView(withId(R.id.main_tv_name)).check(matches(isDisplayed()));
}
}
- Build Variants需要选择debug,不然所写的类识别不到test库的类
