1. 1. Easymock Introduction

EasyMock is a class library that generates mock objects in a simple way for a specified interface or class, which can be used to assist unit testing with impersonation of a docking port or class.

For white-box testing, the code is not parsed until it differs from the expected result.

1. 2. Easymock + junit Unit Test

EasyMock Adopt " Record ----- Playback " working mode, basic use steps:
* Control object for creating mock objects.
* Gets the desired mock object from the control object.
* Record the methods and return values used in the test method.
* Set Control object to "playback" mode.
* To test.
* After the test is complete, confirm that the mock object has performed all the actions just defined.

Public class Talkercontroller {

Public Integer Getresponsebyword (Stringword) {

/*if (word== "I'm angry! "){

return emotionconstants.very_angry_emotion;

}

else if (Word = = "I'm a little angry") {

Returnemotionconstants.normal_angry_emotion;

}

else if (Word = = "My mind is calm") {

Returnemotionconstants.normal_emotion;

}

else if (Word = = "I'm a little happy") {

Returnemotionconstants.normal_happy_emotion;

}

else if (Word = = "I'm Happy") {

return emotionconstants.very_happy_emotion;

}else{

return 0;

}*/

return 0;

}

Easymock To test the class initialization code:

@Before

Public voidinit () {

Calmotion = new calculatemotion ();

Talkermock = EasyMock. Createmock (Talkercontroller. class);

Calmotion.setcontroller (Talkermock);}

Easymock test class implementation functions Getresponsebyword Code:

@Test

Public void caltest () throwsexception{

EasyMock. expect (Talkermock.getresponsebyword ("I'm angry!")

")). Andreturn (5);

EasyMock. expect (Talkermock.getresponsebyword ("I'm happy

")). Andreturn (1);

EasyMock. Replay (Talkermock);

Humana = newHuman ("I'm angry!" ", 1);

HUMANB = newHuman ("I'm Happy", 1);

Calmotion.gethumanlist (). Add (a);

Calmotion.gethumanlist (). Add (b);

int total = Calmotion.calculateavgmotion ();

System. out. println ("Total motion:" +total);

Assert. assertequals (6,total);

}

1. 3. easymock +spring + junit4

Easymock test the class-critical code:

JUNIT4 test Suites for:

@RunWith (Suite.class)

Specify the Runner

@Suite. suiteclasses ({calculatortest.class, parameterstest.class})

Specify the class to test

public class Testall

{

}

@RunWith (Suite.class)

@SuiteClasses (Testall.class)

In addition to specifying a class, you can also specify a suite class

public class TestAll2

{

}

1. 4. Junit main syntax

JUNIT4 Use Java5 the annotations in the ( annotation ), the following is JUNIT4 a few common annotation :

* @Before: Initialization method is performed once for each test method (note the difference from Beforeclass, which is performed once for all methods)

* @After: Releasing resources is performed once for each test method (note the difference from Afterclass, which is

Have method to execute once)

* @Test: Test method, where you can test the expected exception and timeout time

* @Test (Expected=arithmeticexception.class) Check if the method being tested throws ArithmeticException exception

* @Ignore: Ignored test methods

* @BeforeClass: For all tests, execute only once and must be static void

* @AfterClass: For all tests, execute only once and must be static void

* A JUNIT4 unit test case Execution sequence is:

* @AfterClass, @After, @Test, @Before, @BeforeClass

* The sequence of calls for each test method is:

* @After, @Test, @Before;
