PageObject

老马关于PageObject的定义

PageObject到底是个啥

E2E的几个痛点
- 前端调整引起元素定位不到，如
- 相同的页面操作，要在不同的地方使用，写N次，代码冗余，很不利于后期维护
使用PageObject都可以解决
- 如果元素定位不到，只需要修改对应的页面的PageObject就好，一处改动，关联的地方都OK了
- 将相同的页面操作，进行抽离至PageObject中，大大减少代码的冗余

分离PageObject

原始代码

public class ExampleInstrumentedTest {


    public static final String STRING_TO_BE_TYPED_EMAIL = "EspressoDemo@mail.com";
    public static final String STRING_TO_BE_TYPED_EMAIL_PASSWORD = "123456";

    @Rule
    public ActivityTestRule<LoginActivity> mActivityRule = new ActivityTestRule<>(
            LoginActivity.class);

    @Test
    public void testAttemptLogin() {
        // Type text and then press the button.
        onView(withId(demo.test.espressodemo.R.id.email))
                .perform(typeText(STRING_TO_BE_TYPED_EMAIL), closeSoftKeyboard());
        onView(withId(demo.test.espressodemo.R.id.email))
                .check(matches(withText(STRING_TO_BE_TYPED_EMAIL)));

        onView(withId(demo.test.espressodemo.R.id.password))
                .perform(typeText(STRING_TO_BE_TYPED_EMAIL_PASSWORD), closeSoftKeyboard());
        onView(withId(demo.test.espressodemo.R.id.password))
                .check(matches(withText(STRING_TO_BE_TYPED_EMAIL_PASSWORD)));

        onView(withId(demo.test.espressodemo.R.id.email_sign_in_button))
                .perform(click());

    }
}

从testAttemptLogin中可以看出测试流程是这样

第一步: R.id.email输入内容STRING_TO_BE_TYPED_EMAIL，再验证输入内容是否为STRING_TO_BE_TYPED_EMAIL
第二步: R.id.password输入内容STRING_TO_BE_TYPED_EMAIL_PASSWORD，再验证输入内容是否为STRING_TO_BE_TYPED_EMAIL_PASSWORD
第三步: 点击R.id.email_sign_in_button按钮

`分离`手术

提取登录PageObject: LoginPageObject

public class LoginPageObject {

    public static void inputEmail(String email){
        onView(withId(demo.test.espressodemo.R.id.email))
                .perform(typeText(email), closeSoftKeyboard());
        onView(withId(demo.test.espressodemo.R.id.email))
                .check(matches(withText(email)));
    }

    public static void inputPassword(String password){
        onView(withId(demo.test.espressodemo.R.id.password))
                .perform(typeText(password), closeSoftKeyboard());
        onView(withId(demo.test.espressodemo.R.id.password))
                .check(matches(withText(password)));
    }

    public static void clickLogin(){
        onView(withId(demo.test.espressodemo.R.id.email_sign_in_button))
                .perform(click());
    }
}

使用登录PageObject来实现之前的测试功能

public class ExampleInstrumentedTest {
    public static final String email = "EspressoDemo@mail.com";
    public static final String password = "123456";

    @Rule
    public ActivityTestRule<LoginActivity> mActivityRule = new ActivityTestRule<>(
            LoginActivity.class);

    @Test
    public void testAttemptLogin() {
        // Type text and then press the button.

        LoginPageObject.inputEmail(email);

        LoginPageObject.inputPassword(password);

        LoginPageObject.clickLogin();

    }
}

提取用户数据: UserInfo

public class UserInfo {
    public static final String email = "EspressoDemo@mail.com";
    public static final String password = "123456";

}

再次调整测试代码

public class ExampleInstrumentedTest {

    @Rule
    public ActivityTestRule<LoginActivity> mActivityRule = new ActivityTestRule<>(
            LoginActivity.class);

    @Test
    public void testAttemptLogin() {
        // Type text and then press the button.

        LoginPageObject.inputEmail(UserInfo.email);

        LoginPageObject.inputPassword(UserInfo.password);

        LoginPageObject.clickLogin();

    }
}

测试仅有三步骤
