TestNG - 依存関係テスト

TestNG –依存関係テスト

TestNGでは、dependOnMethodsとdependsOnGroupsを使用して依存関係テストを実装します。 依存メソッドが失敗した場合、後続のすべてのテストメソッドはスキップされ、失敗しません。

1. dependOnMethodsの例

簡単な例「method2（）」は「method1（）」に依存しています。

1.1method1()が渡されると、method2()が実行されます。

App.java

package com.example.testng.examples.dependency;

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");
    }

}

出力 

This is method 1
This is method 2
PASSED: method1
PASSED: method2

===============================================
    Default test
    Tests run: 2, Failures: 0, Skips: 0
===============================================

1.2method1()が失敗した場合、method2()はスキップされます。

App.java

package com.example.testng.examples.dependency;

import org.testng.annotations.Test;

public class App {

    //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");
    }

}

出力 

This is method 1
FAILED: method1
java.lang.RuntimeException
    at com.example.testng.examples.dependency.App.method1(App.java:10)
    //...

SKIPPED: method2

===============================================
    Default test
    Tests run: 2, Failures: 1, Skips: 1
===============================================

2. dependOnGroupsの例

dependsOnMethodsとdependsOnGroupsの混合使用を示すために、いくつかのテストケースを作成しましょう。 自明のコメントを参照してください。

TestServer.java

package com.example.testng.examples.dependency;

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

package com.example.testng.examples.dependency;

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

package com.example.testng.examples.dependency;

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");
    }

}

XMLファイルを作成し、一緒にテストします。
