TestNGでは、依存テストを実装するために
dependOnMethods`と
dependsOnGroups`を使用します。依存するメソッドが失敗した場合、後続のテストメソッドはすべてスキップされ、失敗はされません。
1. dependOnMethodsの例
簡単な例として、 “method2（）”は “method1（）”に依存しています。
App.java
package com.mkyong.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
===============================================
-
1.2 ** `method1（）`が失敗した場合、 `method2（）`はスキップされます。
App.java
package com.mkyong.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.mkyong.testng.examples.dependency.App.method1(App.java:10)
//...
SKIPPED: method2
===============================================
Default test
Tests run: 2, Failures: 1, Skips: 1
===============================================
2. dependsOnGroupsの例
dependsOnMethods`と
dependsOnGroups`を混在して使用する方法を示すために、いくつかのテストケースを作成しましょう。自己説明的なコメントを参照してください。
TestServer.java
package com.mkyong.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.mkyong.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.mkyong.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、それらを一緒にテストします。
