1 @factory，注解是用来传递不同的参数给测试的，
如果一个测试类的很多方法需要测试，而且这个测试类需要多次测试那么需要使用测试工厂最好。
比如最简单的：
   

@Test
public void simpleTest(){
System.out.println("Simple Test Method.");
}

@Factory
public Object[] factoryMethod(){
return new Object[]{
new SimpleTest(),
new SimpleTest()
};
}
   

    而
       @Factory
public Object[] paramFactory(){
return new Object[]{
new ParameterTest(0),
new ParameterTest(1)
};
}


2 再看一个例子：
    public class ParameterFactory {

@Factory
public Object[] paramFactory(){
return new Object[]{
new ParameterTest(0),
new ParameterTest(1)
};
}
}

     public class ParameterTest {
private int param;
public ParameterTest(int param){
this.param = param;
}

@Test
public void testMethodOne(){
int opValue=param+1;
System.out.println("Test method one output: "+ opValue);
}

@Test
public void testMethodTwo(){
int opValue=param+2;
System.out.println("Test method two output: "+ opValue);
}
}
        最后的运行结果为：
   Test method one output: 1
Test method one output: 2
Test method two output: 2
Test method two output: 3
   
   3  @Dataprovider
        public class TestParameterDataProvider {

@Test(dataProvider = "provideNumbers")
public void test(int number, int expected) {
Assert.assertEquals(number + 10, expected);
}

@DataProvider(name = "provideNumbers")
public Object[][] provideData() {

return new Object[][] {
{ 10, 20 },
{ 100, 110 },
{ 200, 210 }
};
}

}

  输出：
      PASSED: test(10, 20)
PASSED: test(100, 110)
PASSED: test(200, 210)
   
    4  @DataProvider + Method
        @Test(dataProvider = "dataProvider")
public void test1(int number, int expected) {
Assert.assertEquals(number, expected);
}

@Test(dataProvider = "dataProvider")
public void test2(String email, String expected) {
Assert.assertEquals(email, expected);
}

@DataProvider(name = "dataProvider")
public Object[][] provideData(Method method) {

Object[][] result = null;

if (method.getName().equals("test1")) {
result = new Object[][] {
{ 1, 1 }, { 200, 200 }
};
} else if (method.getName().equals("test2")) {
result = new Object[][] {
{ "[e-mail]", "[e-mail]" },
{ "[e-mail]", "[e-mail]" }
};
}

return result;

}
输出：
    PASSED: test1(1, 1)
PASSED: test1(200, 200)
PASSED: test2("[e-mail]", "[e-mail]")
PASSED: test2("[e-mail]", "[e-mail]")
   

    5  并行测试：
        下面的例子介绍了如何同时开两个线程来测试：
  @Test
public void testMethodsOne() {
long id = Thread.currentThread().getId();
System.out.println("Simple test-method One. Thread id is: "+id);
}

@Test
public void testMethodsTwo() {
long id = Thread.currentThread().getId();
System.out.println("Simple test-method Two. Thread id is: "+id);
}

<suite name="Simple Suite" parallel="methods" thread-count="2"  >
<test name="Simple test">
<classes>
<class name="test.parallelism.SimpleClass" />
</classes>
</test>
</suite>
    
       thread-count指定用2个线程来测试


    6  并行测试不同的类
        比如类一：

public class SampleTestClassOne {
@BeforeClass
public void beforeClass(){
long id = Thread.currentThread().getId();
System.out.println("Before test-class SampleTestClassOne. Thread id is: "+id);
}

@Test
public void testMethodOne() {
long id = Thread.currentThread().getId();
System.out.println("Sample test-method One SampleTestClassOne. Thread id is: "+id);
}

@Test
public void testMethodTwo() {
long id = Thread.currentThread().getId();
System.out.println("Sample test-method Two SampleTestClassOne. Thread id is: "+id);
}

@AfterClass
public void afterClass(){
long id = Thread.currentThread().getId();
System.out.println("After test-method SampleTestClassOne. Thread id is: "+id);
}


类2 ：
    <suite name="Test-class Suite" parallel="classes" thread-count="2"  >
<test name="Test-class test" group-by-instances="true">
<classes>
<class name="test.parallelism.SampleTestClassOne" />
<class name="test.parallelism.SampleTestClassTwo" />
</classes>
</test>
</suite>

    7 同时测试两个test，如
        <suite name="Parallel tests" parallel="tests" thread-count="2" >
<test name="Test One">
<parameter name="test-name"  value="Test One"/>
<classes>
<class name="test.parallelism.SampleTestSuite" />
</classes>
</test>
<test name="Test Two">
<parameter name="test-name"  value="Test Two"/>
<classes>
<class name="test.parallelism.SampleTestSuite" />
</classes>
</test>
</suite>

     使用parallel="tests"进行测试
        public class SampleTestSuite {
String testName="";

@BeforeTest
@Parameters({ "test-name" })
public void beforeTest(String testName){
this.testName=testName;
long id = Thread.currentThread().getId();
System.out.println("Before test "+testName+". Thread id is: "+id);
}

@BeforeClass
public void beforeClass(){
long id = Thread.currentThread().getId();
System.out.println("Before test-class "+testName+". Thread id is: "+id);
}

@Test
public void testMethodOne() {
long id = Thread.currentThread().getId();
System.out.println("Sample test-method "+testName+". Thread id is: "+id);
}

@AfterClass
public void afterClass(){
long id = Thread.currentThread().getId();
System.out.println("After test-method  "+testName+". Thread id is: "+id);
}

@AfterTest
public void afterTest(){
long id = Thread.currentThread().getId();
System.out.println("After test  "+testName+". Thread id is: "+id);
}

输出：
   Before test Test One. Thread id is: 9
Before test Test Two. Thread id is: 10
Before test-class Test One. Thread id is: 9
Before test-class Test Two. Thread id is: 10
Sample test-method Test One. Thread id is: 9
Sample test-method Test Two. Thread id is: 10
After test-method  Test One. Thread id is: 9
After test-method  Test Two. Thread id is: 10
After test  Test One. Thread id is: 9
After test  Test Two. Thread id is: 10


8  在多线程中运行单独的测试
    public class IndependentTestThreading {
@Test(threadPoolSize=3,invocationCount=6,timeOut=1000)
public void testMethod(){
Long id = Thread.currentThread().getId();
System.out.println("Test method executing on thread with id: "+id);
}
}
     其中，threadPoolSize=3表示在三个不同的线程中运行，invocationCount表示执行次数，timeOut表示执行多少毫秒就失败
      Test method executing on thread with id: 11
Test method executing on thread with id: 10
Test method executing on thread with id: 9
Test method executing on thread with id: 11
Test method executing on thread with id: 10
Test method executing on thread with id: 9
