TestNG依賴性測試

有時,我們可能需要以特定順序調(diào)用測試用例中的方法,或者可能希望在方法之間共享一些數(shù)據(jù)和狀態(tài)。 TestNG支持這種依賴關(guān)系,因為它支持在測試方法之間顯式依賴的聲明。

TestNG允許指定依賴關(guān)系:

  • @Test注釋中使用屬性dependsOnMethods,或者
  • @Test注釋中使用屬性dependsOnGroups。

在TestNG中,我們使用dependOnMethodsdependsOnGroups來實現(xiàn)依賴測試。 如果依賴方法失敗,則將跳過所有后續(xù)測試方法。

為了方便演示使用,首先創(chuàng)建一個 Maven 項目: DependOnTest,其項目結(jié)構(gòu)如下所示 -

1. dependOnMethods示例

一個簡單的例子,“method2()”依賴于“method1()”。

1.1. 如果method1()通過,那么將執(zhí)行method2()。

創(chuàng)建一個Java文件: App.java,其代碼結(jié)構(gòu)如下所示 -

package com.yiibai;

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");
    }

}

執(zhí)行上面代碼,得到以下結(jié)果 -

1.2. 如果method1()失敗,則將跳過method2()。

創(chuàng)建一個Java文件: App2.java,其代碼結(jié)構(gòu)如下所示 -

package com.yiibai;

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");
    }

}

執(zhí)行上面代碼,得到以下結(jié)果 -

2. dependsOnGroups示例

下面我們創(chuàng)建幾個測試用例來證明dependsOnMethodsdependsOnGroups的混合使用。 代碼比較簡單,參閱下面注釋就能明白了。

創(chuàng)建一個Java文件: TestServer.java,其代碼結(jié)構(gòu)如下所示 -

package com.yiibai;

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...");
    }

}

創(chuàng)建一個Java文件: TestDatabase.java,其代碼結(jié)構(gòu)如下所示 -

package com.yiibai;

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()");
    }

}

創(chuàng)建一個Java文件: TestApp.java,其代碼結(jié)構(gòu)如下所示 -

package com.yiibai;

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");
    }

}

創(chuàng)建一個XML文件: testng.xml,其代碼結(jié)構(gòu)如下所示 -

<?xml version="1.0" encoding="UTF-8"?>
<suite name="TestDependency">

  <test name="TestCase1">

    <classes>
      <class
        name="com.yiibai.TestApp">
      </class>
      <class
        name="com.yiibai.TestDatabase">
      </class>
      <class
        name="com.yiibai.TestServer">
      </class>
    </classes>

  </test>

</suite>

執(zhí)行上面代碼,得到以下結(jié)果 -

[TestNG] Running:
  F:\worksp\testng\DependOnTest\src\main\java\com\yiibai\testng.xml

Deploying Server...
Deploying Backup Server...
This is initDB()
This is testConnection()
This is method 1
This is method 2
