自動化測試示例

下面示例一個Android項目，就是一個簡單的登錄頁面，依次使用上面介紹的自動化測試方案測試界面。

首先是界面布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/activity_main"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="20dp"
    tools:context="cn.mycommons.testcase.MainActivity">

    <EditText
        android:id="@+id/edtUserName"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:hint="Input user name" />

    <EditText
        android:id="@+id/edtPasswd"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:hint="Input password"
        android:contentDescription="Input password"
        android:inputType="textPassword" />

    <Button
        android:id="@+id/btnLogin"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:text="Login" />
</LinearLayout>

其次是頁面代碼：

package cn.mycommons.testcase;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    EditText edtUserName;
    EditText edtPasswd;
    Button btnLogin;

    String userName;
    String passwd;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        edtUserName = (EditText) findViewById(R.id.edtUserName);
        edtPasswd = (EditText) findViewById(R.id.edtPasswd);
        btnLogin = (Button) findViewById(R.id.btnLogin);

        btnLogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                userName = edtUserName.getText().toString();
                passwd = edtPasswd.getText().toString();
                if (check(userName, passwd)) {
                    doLogin(userName, passwd);
                }
            }
        });
    }

    boolean check(String userName, String passwd) {
        do {
            if (userName.length() < 5) {
                showToast("User name invalidate");
                break;
            }
            if (passwd.length() < 5) {
                showToast("Password invalidate");
                break;
            }
            return true;
        } while (false);
        return false;
    }

    void doLogin(String userName, String passwd) {
        if ("admin".equals(userName) && "admin".equals(passwd)) {
            showToast("Login success");
            startActivity(new Intent(this, SuccessActivity.class));
        } else {
            showToast("Login fail");
        }
    }

    void showToast(String msg) {
        Toast.makeText(this, msg, Toast.LENGTH_SHORT).show();
    }
}

Monkey

Monkey只是檢查使用下shell命令即可。

adb shell monkey -p cn.mycommons.testcase -v 50000

Monkey Runner

Monkey Runner提供的是一個python文件，然后調用monkeyrunner命令即可。

$ monkeyrunner test_case.py

# Imports the monkeyrunner modules used by this program
from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice

# Connects to the current device, returning a MonkeyDevice object
print 'wait for device connection.'
device = MonkeyRunner.waitForConnection()
print 'connect device success.'

# Takes a screenshot
result = device.takeSnapshot()
print 'takeSnapshot success.'
# Writes the screenshot to a file
result.writeToFile('./test_case1.png','png')
print 'save image to file success.'

# input user name
device.touch(200,380,'DOWN_AND_UP')
print 'touch user name'
for x in xrange(1,100):
    device.press("KEYCODE_DEL",'DOWN_AND_UP')
print 'delete user name'
device.type("admin")
print 'input admin to user name'

# input passwd 
device.touch(200,500,'DOWN_AND_UP')
print 'touch password'
for x in xrange(1,100):
    device.press("KEYCODE_DEL",'DOWN_AND_UP')
print 'delete password'
device.type("admin")
print 'input admin to password'

# press login button
device.touch(200,680,'DOWN_AND_UP')
print 'press login button'

MonkeyRunner.sleep(2)

# Takes a screenshot
result = device.takeSnapshot()
print 'takeSnapshot success.'
# Writes the screenshot to a file
result.writeToFile('./test_case2.png','png')
print 'save image to file success.'

    @Test
    public void testLogin() {
        Espresso.onView(ViewMatchers.withContentDescription(R.id.edtUserName)).perform(ViewActions.typeText("admin"));
        Espresso.onView(ViewMatchers.withId(R.id.edtPasswd)).perform(ViewActions.typeText("admin"));

自動化測試總結

  • Monkey
    準確來說，這不算是自動化測試，因為其只能產生隨機的事件，無法按照既定的步驟操作；

  • Monkeyrunner
    優點：操作最為簡單，可以錄制測試腳本，可視化操作；
    缺點：主要生成坐標的自動化操作，移植性不強，功能最為局限，上面代碼中已經顯示出來，完全使用的數字坐標，移植到另外一個設備，則不能運行。

  • UiAutomator
    優點：可以對所有操作進行自動化，操作簡單；
    缺點：Android版本需要高于4.3，無法根據控件ID操作，相對來說功能較為局限，但也夠用了；

  • Espresso
    優點：主要針對某一個APK進行自動化測試，APK可以有源碼，也可以沒有源碼，功能強大；
    缺點：針對APK操作，因此操作相對復雜；

總結：由上面介紹可以有這樣的結論：測試某個APK，可以選擇Espresso；測試過程可能涉及多個APK，選擇UiAutomator；一些簡單的測試，選擇Monkeyrunner；
