Robotium的測試類ActivityInstrumentationTestCase2是繼承于Junit3的TestCase類，所以并沒有提供Junit4的特性.如網(wǎng)上總結(jié)說的

• 不能通過annotate的方式來識別子類的新特征，如不能實現(xiàn)@beforeclass，@afterclass等特征。只能通過寫setup和teardown，
• TestCase只能以test開頭進行測試case書寫。

那么有時我們并不想每次開始/完成一個case的時候都做一些重復(fù)的動作，也就是要實現(xiàn)Junit4的@beforeclass和@afterclass，該怎么辦呢？ 以SDK自帶的Notepad測試用例作為例子，假如現(xiàn)在我們需要實現(xiàn)兩個測試用例

• testAddNoteCNTittle:創(chuàng)建一個中文標(biāo)題的筆記
• testAddNoteEngTitle:創(chuàng)建一個英文標(biāo)題的筆記

根據(jù)實例提供的代碼，在setup里面會初始化solo而在teardown里面會關(guān)閉所有打開的activities，也就是說每執(zhí)行一個case都會重新初始化一次solo和關(guān)閉所有的activities： @Overridepublic void setUp() throws Exception {//setUp() is run before a test case is started. //This is where the solo object is created.super.setUp();this.activity = this.getActivity();this.solo = new Solo(getInstrumentation(), getActivity());}@Overridepublic void tearDown() throws Exception {//tearDown() is run after a test case has finished. //finishOpenedActivities() will finish all the activities that have been opened during the test execution.solo.finishOpenedActivities();} 但事實上我們在這個腳本只是去創(chuàng)建兩個Note，并不需要每執(zhí)行完一個case都要去初始化solo和關(guān)閉所有activities。google后沒有發(fā)現(xiàn)有現(xiàn)成的取代@beforeclass和@aferclass的方法。 以下本人的實現(xiàn)方法 <pre name="code" class="java">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;<span style="white-space:pre"> </span>private static final int NUMBER_TOTAL_CASES = 2;private static int run = 0;private static Class<?> launchActivityClass;//對應(yīng)re-sign.jar生成出來的信息框里的兩個值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);}@Overridepublic void setUp() throws Exception {//setUp() is run before a test case is started. //This is where the solo object is created.super.setUp(); <span style="white-space:pre"> </span>//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 staticif(solo == null) {TCCreateNote.solo = new Solo(getInstrumentation(), getActivity());}}@Overridepublic 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, "中文標(biāo)簽筆記");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("中文標(biāo)簽筆記");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");} }
