Ios7 initial experience (2) -- unit test

In xcode 4.6 and earlier versions, I always felt that the unit test function was very poor and it was quite awkward to use. This time xcode 5.0 introduces unit testing by default. Let's take a look at the improvements compared with previous versions !~ _~

1. First open the project used in the previous example. Of course, you can also create a blank project;

2. First check the toolbar of the navigation area. What are the changes compared with 4.6, as shown in:

It is not hard to find that there is one moreShow the test Navigator(Display Test Navigator);

3. PressCommand + uRun unit test ...... After a few seconds, you canIssue Navigator(Question Navigator)See a message similar to 4.6, as shown in:

4. ClickShow the test Navigator(Display Test Navigator)As shown in:

5. InHelloworldtests. mFile,@ EndAdd the followingCode:

-(Void) Testexample2 {xctasserttrue (1=1,@"Just a test");}
 

6. PressCommand + uRun unit test ...... After a few seconds, you canTest NavigatorSee the following test results:

7. In the navigation areaTestexample2Right-click, and the secondary menu is displayed, as shown in:

In the figure, you can see thatRun/DisableA unit test ~ _~.

Remarks: If you selectTest "testexample2"It's not hard to find that, in factTestexampleAndTestexample2Both unit tests run andProblem navigation areaAll test results are displayed inTest navigation areaBut only updateTestexample2. This problem is expected to be improved in the future xcode version. :]

8. The following shows how to test the data model.HelloworldCreate a new project namedDatamodelClass, inherited fromNsobject;

9. FirstHelloworldRight-click the node and selectNew file..., SelectObjective-C ClassAnd then clickNextButton:

10. In the next dialog boxClassInput:DatamodelAnd confirmSubclass: SelectNsobjectAnd then clickNextButton:

11. Click and openDatamodel. hAdd an attribute definition. The adjusted code is as follows:

 
# Import<Foundation/Foundation. h>@ InterfaceDatamodel: nsobject @ property (assign, nonatomic) nsinteger myid;@ End
 

12. Click and openDatamodel. m, AddInitMethod, SetMyidThe default value is100The adjusted code is as follows:

 
# Import "Datamodel. h"@ ImplementationDatamodel-(ID) Init {If(Self =[Super init]) {_ myid=100;}ReturnSelf ;}@ End
 

13. ClickShow the test Navigator(Display Test Navigator)And right-clickHelloworldtestsIn the pop-up menu, selectNew test class...:

14. In the next dialog boxClassInput:DatamodeltestsAnd confirmSubclass: SelectXctestcaseAnd then clickNextButton, and directly click in the next dialog boxCreateButton:

15. ClickDatamodeltestsNode, first introduceDatamodelHeader file:

 
# Import "Datamodel. h"
 

16. DeleteTestexampleMethod, and then@ EndAdd the following code before:

-(Void) Testmodeldefaultid {datamodel* Model =[[Datamodel alloc] init]; xctassertequals (model. myid,100,@"The default ID shocould be 100");}
 

17. PressCommand + uRun unit test ......

 

Work done!

This article will not go into details about the benefits of unit testing. I believe all of my friends who have experience in Java or. NET development are deeply touched. For more information about unit testing in ios7, see the official documentation of apple.
