TestNG依赖测试
有时，我们可能需要以特定顺序调用测试用例中的方法，或者可能希望在方法之间共享一些数据和状态。 TestNG支持这种依赖关系，因为它支持在测试方法之间显式依赖的声明。
TestNG允许指定依赖关系：
- 在@Test注释中使用属性dependsOnMethods
- 在@Test注释中使用属性dependsOnGroups。
在TestNG中，我们使用dependOnMethods和dependsOnGroups来实现依赖测试。 如果依赖方法失败，则将跳过所有后续测试方法。
1.dependOnMethods示例
一个简单的例子，“method2()”依赖于“method1()”。
1.1. 如果method1()通过，那么将执行method2()。
App.java
import org.testng.annotations.Test;
public class App {
@Test
public void method1() {
System.out.println("This is method 1");
}
@Test(dependsOnMethods = { "method1" })
public void method2() {
System.out.println("This is method 2");
}
}
运行日志：
This is method 1
This is method 2

1.2. 如果method1()失败，则将跳过method2()。
App2.java
import org.testng.annotations.Test;
public class App2 {
// This test will be failed.
@Test
public void method1() {
System.out.println("This is method 1");
throw new RuntimeException();
}
@Test(dependsOnMethods = { "method1" })
public void method2() {
System.out.println("This is method 2");
}
}
日志如下：
This is method 1

2. dependsOnGroups示例
下面我们创建几个测试用例来证明dependsOnMethods和dependsOnGroups的混合使用。 代码比较简单，参阅下面注释就能明白了。
TestService.java
import org.testng.annotations.Test;
//all methods of this class are belong to "deploy" group.
@Test(groups = "deploy")
public class TestServer {
@Test
public void deployServer() {
System.out.println("Deploying Server...");
}
// Run this if deployServer() is passed.
@Test(dependsOnMethods = "deployServer")
public void deployBackUpServer() {
System.out.println("Deploying Backup Server...");
}
}
TestDatabase.java
import org.testng.annotations.Test;
public class TestDatabase {
//belong to "db" group,
//Run if all methods from "deploy" group are passed.
@Test(groups="db", dependsOnGroups="deploy")
public void initDB() {
System.out.println("This is initDB()");
}
//belong to "db" group,
//Run if "initDB" method is passed.
@Test(dependsOnMethods = { "initDB" }, groups="db")
public void testConnection() {
System.out.println("This is testConnection()");
}
}
TestApp.java
import org.testng.annotations.Test;
public class TestApp {
//Run if all methods from "deploy" and "db" groups are passed.
@Test(dependsOnGroups={"deploy","db"})
public void method1() {
System.out.println("This is method 1");
//throw new RuntimeException();
}
//Run if method1() is passed.
@Test(dependsOnMethods = { "method1" })
public void method2() {
System.out.println("This is method 2");
}
}

解读：
1.套件测试，测试用例1：测试TsesApp、测试TestDatabase、测试TestService。 2.TestApp: 依赖deplay组和db组，db组、所以先运行这两个组，然后运行TestApp。 3.TestDatabase：已经运行过，所以不需要再运行。 4.TestService：同理，不再运行。
