Robotium Writing test Cases How to simulate the Beforeclass and Afterclass methods of JUNIT4 1-Conditional judgment method

This article is from: http://blog.csdn.net/zhubaitian/article/details/39293883

Robotium's test class ActivityInstrumentationTestCase2 is a TestCase class that inherits from Junit3, so it does not provide JUNIT4 features. As the online summary says:

1, can not be annotate way to identify the new characteristics of subclasses, such as can not achieve @beforeclass, @afterclass and other characteristics. Only by writing setup and teardown,

2. TestCase can only test case writing with test opening.

So sometimes we don't want to do something repetitive every time we start/complete a case, that is, to achieve JUNIT4 @beforeclass and @afterclass, what should we do?
Take the SDK's own Notepad test case as an example, if now we need to implement two test cases
1, Testaddnotecntittle: Create a Chinese title note

2, Testaddnoteengtitle: Create a note in English title

According to the code provided by the instance, the solo will be initialized in Setup and all open activities will be closed in teardown, i.e. each case will be reinitialized once and all activities are closed:

1 @Override2  Public voidSetUp ()throwsException {3     //setUp () is the 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 =NewSolo (Getinstrumentation (), getactivity ());8 }9     Ten @Override One  Public voidTearDown ()throwsException { A     //TearDown () is the run after a test case has finished. -     //finishopenedactivities () would finish all the activities that has been opened during the test execution. - solo.finishopenedactivities (); the}

But the fact that we're just going to create two note in this script does not need to initialize the solo and close all activities for each case executed. Google did not find a readily available alternative to @beforeclass and @aferclass.
The following methods of implementation
