TestNG - 依赖测试

有时，您可能需要以特定顺序调用测试用例中的方法，或者您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，因为它支持测试方法之间显式依赖关系的声明。

TestNG 允许您指定依赖项 -

• 在@Test 注释中使用属性dependsOnMethods，或者。
• 在@Test 注释中使用属性dependsOnGroups。

使用dependsOnMethods 的示例

要测试的java类

public class MessageUtil {private String message;// Constructor// @param message to be printedpublic MessageUtil(String message) {this.message = message;}// prints the messagepublic String printMessage() {System.out.println(message);return message;}// add "Hi!" to the messagepublic String salutationMessage() {message = "Hi!" + message;System.out.println(message);return message;}
}

测试案例

import org.testng.Assert;
import org.testng.annotations.Test;
public class DependencyTestUsingAnnotation {
String message = "Manisha";
MessageUtil messageUtil = new MessageUtil(message);@Testpublic void testPrintMessage() {System.out.println("Inside testPrintMessage()");message = "Manisha";Assert.assertEquals(message, messageUtil.printMessage());}@Test(dependsOnMethods = { "initEnvironmentTest" })public void testSalutationMessage() {System.out.println("Inside testSalutationMessage()");message = "Hi!" + "Manisha";Assert.assertEquals(message, messageUtil.salutationMessage());}@Testpublic void initEnvironmentTest() {System.out.println("This is initEnvironmentTest");}
}

输出结果

This is initEnvironmentTest
Inside testPrintMessage()
Manisha
Inside testSalutationMessage()

示例使用dependsOnGroups

您还可以拥有依赖于整个组的方法。让我们举一个例子来证明这一点。

创建一个类

创建一个要测试的java类，比如说， MessageUtil.java 在 /work/testng/src.

public class MessageUtil {private String message;// Constructor// @param message to be printedpublic MessageUtil(String message) {this.message = message;}// prints the messagepublic String printMessage() {System.out.println(message);return message;}// add "Hi!" to the messagepublic String salutationMessage() {message = "Hi!" + message;System.out.println(message);return message;}
}

创建测试用例类

• 创建一个 java 测试类，比如 DependencyTestUsingAnnotation.java。
• 将测试方法、testPrintMessage()、testSalutationMessage() 和 initEnvironmentTest() 添加到您的测试类，并将它们添加到“init”组中。
• 添加属性 dependsOnMethods = {“init.*”} 到@Test注解 testSalutationMessage() 方法。

创建一个名为的java类文件 DependencyTestUsingAnnotation.java 在 /work/testng/src.

import org.testng.Assert;
import org.testng.annotations.Test;
public class DependencyTestUsingAnnotation {String message = "Manisha";MessageUtil messageUtil = new MessageUtil(message);@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());}@Test(groups = { "init" })public void initEnvironmentTest() {System.out.println("This is initEnvironmentTest");}
}

验证输出

This is initEnvironmentTest
Inside testPrintMessage()
Manisha
Inside testSalutationMessage()
