espresso测试框架简单使用

参考文章 http://blog.csdn.net/qiang_xi/article/details/52933593
buid.gradle
testCompile ‘junit:junit:4.12’
androidTestCompile ‘com.android.support.test.espresso:espresso-core:2.2.+’
androidTestCompile ‘com.android.support.test:runner:0.4.+’
androidTestCompile ‘com.android.support.test:rules:0.2’

如果报错
android{
configurations.all {
resolutionStrategy.force ‘com.android.support:support-annotations:23.0.1’
}
}

defaultConfig {
“android.support.test.runner.AndroidJUnitRunner”
}

android studio配置

在测试目录下 新建测试类

下面是模拟登录的代码

@RunWith(AndroidJUnit4.class)
public class MainActivityTest {

@Rule

// 注解定义规则

public ActivityTestRule<MainActivity> mActivityRule = new ActivityTestRule<>(

        MainActivity.class);

@Test

// 测试用例

public void test(){

    // 清除 之前输入点用户名和密码

    onView(withId(R.id.editTextName)).perform(clearText());

    onView(withId(R.id.editTextPassWord)).perform(clearText());

    // 输入用户名和密码并关闭软键盘

    onView(withId(R.id.editTextName)).perform(typeText("18500000000\n"), closeSoftKeyboard());

    onView(withId(R.id.editTextPassWord)).perform(typeText("wjf"),closeSoftKeyboard());

    // 触发登录按钮的点击事件

    onView(withId(R.id.btn_login)).perform(click());

    //通过断言判断是否登录成功,这里通过会话列表是否显示来判断

// onView(withId(R.id.list_fl_list)).check(ViewAssertions.matches(isDisplayed()));

}
