Android study Note 5 -------- business bean (unit test ).

The unit test of android is very easy to use. It can detect whether your function classes or methods are correct without relying on complicated operations.
Unit Test Configuration:

1. The unit test class inherits AndroidTestCase

2. Add AndroidManifest. xml file

<Uses-library android: name = "android. test. runner"> </uses-library>

<Instrumentation
Android: name = "android. test. InstrumentationTestRunner"
Android: targetPackage = "com. luku. log" // your package name
Android: label = "Test for my app"
> </Instrumentation>

3. Compile the test class

Example:

[Java]
Import android. test. AndroidTestCase;
Import android. util. Log;
 
Public class test extends AndroidTestCase
{
Public void add () throws Exception
{
Int I = 1 + 1;
Xxx ();
Log. I ("test", "result =" + I );
}

Public String xxx ()
{
String str = "output ";

Int I = 1;
Int x = 2;
Int c = I + x;
Str = str + c;
Return str;
}
}
Import android. test. AndroidTestCase;
Import android. util. Log;

Public class test extends AndroidTestCase
{
Public void add () throws Exception
{
Int I = 1 + 1;
Xxx ();
Log. I ("test", "result =" + I );
}
 
Public String xxx ()
{
String str = "output ";

Int I = 1;
Int x = 2;
Int c = I + x;
Str = str + c;
Return str;
}
}
 

 

[Java]
<? Xml version = "1.0" encoding = "UTF-8"?>
<Manifest xmlns: android = "http://schemas.android.com/apk/res/android"
Package = "com. luku. log"
Android: versionCode = "1"
Android: versionName = "1.0" type = "codeph" text = "/codeph">
<Uses-sdk android: minSdkVersion = "8"/>

<Application android: icon = "@ drawable/icon" android: label = "@ string/app_name">
<Uses-library android: name = "android. test. runner"> </uses-library>
<Activity android: name = ". LogActivity"
Android: label = "@ string/app_name">
<Intent-filter>
<Action android: name = "android. intent. action. MAIN"/>
<Category android: name = "android. intent. category. LAUNCHER"/>
</Intent-filter>
</Activity>
 
</Application>

<Instrumentation
Android: name = "android. test. InstrumentationTestRunner"
Android: targetPackage = "com. luku. log"
Android: label = "Test for my app"
> </Instrumentation>
</Manifest>
