本文整理了Java中junit.framework.TestCase类的一些代码示例，展示了TestCase类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。TestCase类的具体详情如下：
包路径：junit.framework.TestCase
类名称：TestCase

TestCase介绍

[英]A test case defines the fixture to run multiple tests. To define a test case

  1. implement a subclass of TestCase
  2. define instance variables that store the state of the fixture
  3. initialize the fixture state by overriding #setUp()
  4. clean-up after a test by overriding #tearDown().
    Each test runs in its own fixture so there can be no side effects among test runs. Here is an example:
public class MathTest extends TestCase { 
protected double fValue1; 
protected double fValue2; 
protected void setUp() { 
fValue1= 2.0; 
fValue2= 3.0; 
} 
}

For each test implement a method which interacts with the fixture. Verify the expected results with assertions specified by calling junit.framework.Assert#assertTrue(String,boolean) with a boolean.

public void testAdd() { 
double result= fValue1 + fValue2; 
assertTrue(result == 5.0); 
}

Once the methods are defined you can run them. The framework supports both a static type safe and more dynamic way to run a test. In the static way you override the runTest method and define the method to be invoked. A convenient way to do so is with an anonymous inner class.

TestCase test= new MathTest("add") { 
public void runTest() { 
testAdd(); 
} 
}; 
test.run();

The dynamic way uses reflection to implement #runTest(). It dynamically finds and invokes a method. In this case the name of the test case has to correspond to the test method to be run.

TestCase test= new MathTest("testAdd"); 
test.run();

The tests to be run can be collected into a TestSuite. JUnit provides different test runners which can run a test suite and collect the results. A test runner either expects a static method suite as the entry point to get a test to run or it will extract the suite automatically.

public static Test suite() { 
suite.addTest(new MathTest("testAdd")); 
suite.addTest(new MathTest("testDivideByZero")); 
return suite; 
}

[中]测试用例定义了运行多个测试的夹具。定义测试用例
1.实现TestCase的子类
1.定义存储设备状态的实例变量
1.通过覆盖#setUp（）初始化设备状态
1.在测试后通过覆盖#拆卸（）进行清理。
每个测试都在自己的夹具中运行，因此测试运行之间不会产生任何副作用。下面是一个例子：

public class MathTest extends TestCase { 
protected double fValue1; 
protected double fValue2; 
protected void setUp() { 
fValue1= 2.0; 
fValue2= 3.0; 
} 
}

对于每个测试，实现一个与夹具交互的方法。使用调用junit指定的断言验证预期结果。框架Assert#assertTrue（字符串，布尔值）带有布尔值

public void testAdd() { 
double result= fValue1 + fValue2; 
assertTrue(result == 5.0); 
}

一旦定义了这些方法，就可以运行它们。该框架支持静态类型安全和更动态的测试运行方式。以静态方式重写runTest方法并定义要调用的方法。一种方便的方法是使用匿名内部类

TestCase test= new MathTest("add") { 
public void runTest() { 
testAdd(); 
} 
}; 
test.run();

动态方式使用反射来实现#runTest（）。它动态地查找并调用一个方法。在这种情况下，测试用例的名称必须与要运行的测试方法相对应

TestCase test= new MathTest("testAdd"); 
test.run();

要运行的测试可以收集到一个测试套件中。JUnit提供了不同的测试运行程序，可以运行测试套件并收集结果。测试运行者要么期望一个静态方法suite作为让测试运行的入口点，要么将自动提取套件

public static Test suite() { 
suite.addTest(new MathTest("testAdd")); 
suite.addTest(new MathTest("testDivideByZero")); 
return suite; 
}
