TestNG初探

用例包准备？

import org.testng.Assert;
import org.testng.annotations.Test;

前后置用例有哪些？

package com.wj;
import org.testng.annotations.Test;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.AfterSuite;

public class TestngAnnotation {
    // test case1
    @Test
    public void testCase1(){
        System.out.println("        --in test case 1--");
    }

    // test case 2
    @Test
    public void testCase2(){
        System.out.println("        --in test case 2--");
    }

    @BeforeMethod
    public void beforeMethod(){
        System.out.println("      1 in beforeMethod");
    }

    @AfterMethod
    public void afterMethod(){
        System.out.println("      1 in afterMethod");
    }

    @BeforeClass
    public void beforeClass() {
        System.out.println("    2 in beforeClass");
    }
    @AfterClass
    public void afterClass() {
        System.out.println("    2 in afterClass");
    }
    @BeforeTest
    public void beforeTest() {
        System.out.println("  3 in beforeTest");
    }
    @AfterTest
    public void afterTest() {
        System.out.println("  3 in afterTest");
    }
    @BeforeSuite
    public void beforeSuite() {
        System.out.println("4 in beforeSuite");
    }
    @AfterSuite
    public void afterSuite() {
        System.out.println("4 in afterSuite");
    }

}

用例间依赖如何写？

@Test(dependsOnMethods = {"successTest"})
// 如果依赖的用例为真，才执行这个用例，否则直接跳过该用例。
@Test(enabled = false)
@Test(groups = { "init" })
public void testPrintMessage() {
        System.out.println("Inside testPrintMessage()");
        message = "Manisha";
        Assert.assertEquals(message, messageUtil.printMessage());
}

@Test(dependsOnGroups = { "init.*" })
public void testSalutationMessage() {
        System.out.println("Inside testSalutationMessage()");
        message = "Hi!" + "Manisha";
        Assert.assertEquals(message, messageUtil.salutationMessage());
}
// testSalutationMessage在执行前，先去执行所有的init.*的用例。

用例执行顺序？

用例的执行顺序在任何没有其他约束下，就按照用例名称才进行升序排序进行执行。
如果有约束条件，就会先执行依赖的用例，再执行当前用例。

用例参数化？

关键词：the @DataProvider passes Integer and Boolean as parameter.
1.这里的参数是一个基本类型

package com.wj.test;
import com.wj.dependency.PrimeNumberChecker;
import org.testng.Assert;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;
import org.testng.annotations.DataProvider;

public class ParamTestWithDataProvider1 {
    private PrimeNumberChecker primeNumberChecker;

    @BeforeMethod
    public void initalize() {
        primeNumberChecker = new PrimeNumberChecker();

    }

    @DataProvider(name = "test1")
    public static Object[][] primeNumbers() {
        return new Object[][] {
                {2, true}, {6, false}, {19, true}, {22, false}, {23, true}
        };
    }

    @Test(dataProvider = "test1")
    public void testPrimeNumberChecker(Integer inputNumber, Boolean expectedResult) {
        System.out.println(inputNumber + " " + expectedResult);
        Assert.assertEquals(expectedResult, primeNumberChecker.validate(inputNumber));
    }
}

2. 如果参数是一个对象又是怎样的呢？

// 定义一个对象
package com.wj.dependency;


public class Bean {
    private String val;
    private int i;
    public Bean(String val, int i) {
        this.val = val;
        this.i = i;

    }

    public String getVal() {
        return val;
    }

    public void setVal(String val) {
        this.val = val;
    }

    public int getI() {
        return i;
    }

    public void setI(int i) {
        this.i = i;
    }
}

// 去测试这个对象的内容

package com.wj.test;
import com.wj.dependency.Bean;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

public class ParamTestWithDataProvider2 {
    @DataProvider(name = "test1")
    public static Object[][] primeNumbers() {
        return new Object[][] {{ new Bean("hi I am the bean", 111)}};
    }

    @Test(dataProvider = "test1")
    public void testMethod(Bean myBean) {
        System.out.println(myBean.getVal() + " " + myBean.getI());
    }
}

TestNG也很好的集成了Junit！

package com.wj.JUnitDemo;
import org.junit.Test;
import static org.testng.AssertJUnit.assertEquals;

public class TestJunit {
    @Test
    public void testAdd() {
        String str = "Junit testing using TestNG";
        assertEquals("Junit testing using TestNG", str);
    }
}

Test监听器和报告？
