Robotium编写测试用例如何模拟Junit4的BeforeClass和AfterClass方法1 - 条件判断法

Robotium的测试类ActivityInstrumentationTestCase2是继承于Junit3的TestCase类，所以并没有提供Junit4的特性.如网上总结说的：
1、不能通过annotate的方式来识别子类的新特征，如不能实现@beforeclass，@afterclass等特征。只能通过写setup和teardown，
2、TestCase只能以test开头进行测试case书写。
那么有时我们并不想每次开始/完成一个case的时候都做一些重复的动作，也就是要实现Junit4的@beforeclass和@afterclass，该怎么办呢？
以SDK自带的Notepad测试用例作为例子，假如现在我们需要实现两个测试用例
1、testAddNoteCNTittle:创建一个中文标题的笔记
2、testAddNoteEngTitle:创建一个英文标题的笔记
根据实例提供的代码，在setup里面会初始化solo而在teardown里面会关闭所有打开的activities，也就是说每执行一个case都会重新初始化一次solo和关闭所有的activities：
1 @Override 2 public void setUp() throws Exception { 3 //setUp() is run before a test case is started. 4 //This is where the solo object is created. 5 super.setUp(); 6 this.activity = this.getActivity(); 7 this.solo = new Solo(getInstrumentation(), getActivity()); 8 } 9 10 @Override11 public void tearDown() throws Exception {12 //tearDown() is run after a test case has finished. 13 //finishOpenedActivities() will finish all the activities that have been opened during the test execution.14 solo.finishOpenedActivities();15 }
但事实上我们在这个脚本只是去创建两个Note，并不需要每执行完一个case都要去初始化solo和关闭所有activities。google后没有发现有现成的取代@beforeclass和@aferclass的方法。
以下本人的实现方法
package com.example.android.notepad.test;import com.robotium.solo.Solo;import android.test.ActivityInstrumentationTestCase2;import android.app.Activity;@SuppressWarnings("rawtypes")public class TCCreateNote extends ActivityInstrumentationTestCase2{ private static Solo solo = null; public Activity activity; private static final int NUMBER_TOTAL_CASES = 2; private static int run = 0; private static Class<?> launchActivityClass; //对应re-sign.jar生成出来的信息框里的两个值 private static String mainActiviy = com.example.android.notepad.NotesList"; private static String packageName = "com.example.android.notepad"; static { try { launchActivityClass = Class.forName(mainActiviy); } catch (ClassNotFoundException e) { throw new RuntimeException(e); } } @SuppressWarnings("unchecked") public TCCreateNote() { super(packageName, launchActivityClass); } @Override public void setUp() throws Exception { //setUp() is run before a test case is started. //This is where the solo object is created. super.setUp(); //The variable solo has to be static, since every time after a case‘s finished, this class TCCreateNote would be re-instantiated // which would lead to soto to re-instantiated to be null if it‘s not set as static if(solo == null) { TCCreateNote.solo = new Solo(getInstrumentation(), getActivity()); } } @Override public void tearDown() throws Exception { //Check whether it‘s the last case executed. run += countTestCases(); if(run >= NUMBER_TOTAL_CASES) { solo.finishOpenedActivities(); } } public void testAddNoteCNTitle() throws Exception { solo.clickOnMenuItem("Add note"); solo.enterText(0, "中文标签笔记"); solo.clickOnMenuItem("Save"); solo.clickInList(0); solo.clearEditText(0); solo.enterText(0, "Text 1"); solo.clickOnMenuItem("Save"); solo.assertCurrentActivity("Expected NotesList Activity", "NotesList"); solo.clickLongOnText("中文标签笔记"); solo.clickOnText("Delete"); } public void testAddNoteEngTitle() throws Exception { solo.clickOnMenuItem("Add note"); solo.enterText(0, "English Title Note"); solo.clickOnMenuItem("Save"); solo.clickInList(0); solo.clearEditText(0); solo.enterText(0, "Text 1"); solo.clickOnMenuItem("Save"); solo.assertCurrentActivity("Expected NotesList Activity", "NotesList"); solo.clickLongOnText("English Title Note"); solo.clickOnText("Delete"); }}
