@Ignore 用法很简单, 如果你的测试用例还没有准备好而不想被执行, 又不想删掉或注释掉, 可以使用 @Ignore 标注来忽略测试。
-
方法一旦用 @Ignore 注解了将不会被执行.
-
如果一个类用 @Ignore 注解了 他下面的所有测试方法将不会被执行.
看个应用
Create a Class
-
Create a java class to be tested say MessageUtil.java in C: > JUNIT_WORKSPACE
/*
* This class prints the given message on console.
*/
public class MessageUtil { private String message; //Constructor //@param message to be printed public MessageUtil(String message){ this.message = message; } // prints the message public String printMessage(){ System.out.println(message); return message; } // add "Hi!" to the message public String salutationMessage(){ message = "Hi!" + message; System.out.println(message); return message; } } Create Test Case Class
-
Create a java test class say TestJunit.java.
-
Add a test methods testPrintMessage(),testSalutationMessage() to your test class.
-
Add an Annotaion @Ignore to method testPrintMessage().
Create a java class file name TestJunit.java in C: > JUNIT_WORKSPACE
import org.junit.Test; import org.junit.Ignore; import static org.junit.Assert.assertEquals; public class TestJunit { String message = "Robert"; MessageUtil messageUtil = new MessageUtil(message); @Ignore @Test public void testPrintMessage() { System.out.println("Inside testPrintMessage()"); message = "Robert"; assertEquals(message,messageUtil.printMessage()); } @Test public void testSalutationMessage() { System.out.println("Inside testSalutationMessage()"); message = "Hi!" + "Robert"; assertEquals(message,messageUtil.salutationMessage()); } } Create Test Runner Class
Create a java class file name TestRunner.java in C: > JUNIT_WORKSPACE to execute Test case(s)
import org.junit.runner.JUnitCore; import org.junit.runner.Result; import org.junit.runner.notification.Failure; public class TestRunner { public static void main(String[] args) { Result result = JUnitCore.runClasses(TestJunit.class); for (Failure failure : result.getFailures()) { System.out.println(failure.toString()); } System.out.println(result.wasSuccessful()); } } Compile the MessageUtil, Test case and Test Runner classes using javac
C:JUNIT_WORKSPACE>javac MessageUtil.java TestJunit.java TestRunner.java Now run the Test Runner which will not run testPrintMessage() test case defined in provided Test Case class.
C:JUNIT_WORKSPACE>java TestRunner Verify the output. testPrintMessage() test case is not tested.
Inside testSalutationMessage()
Hi!Robert true Now update TestJunit in C: > JUNIT_WORKSPACE to ignore all test cases. Add @Ignore at class level
import org.junit.Test; import org.junit.Ignore; import static org.junit.Assert.assertEquals; @Ignore public class TestJunit { String message = "Robert"; MessageUtil messageUtil = new MessageUtil(message); @Test public void testPrintMessage() { System.out.println("Inside testPrintMessage()"); message = "Robert"; assertEquals(message,messageUtil.printMessage()); } @Test public void testSalutationMessage() { System.out.println("Inside testSalutationMessage()"); message = "Hi!" + "Robert"; assertEquals(message,messageUtil.salutationMessage()); } } Compile the Test case using javac
C:JUNIT_WORKSPACE>javac TestJunit.java Keep your Test Runner unchnaged as follows
import org.junit.runner.JUnitCore; import org.junit.runner.Result; import org.junit.runner.notification.Failure; public class TestRunner { public static void main(String[] args) { Result result = JUnitCore.runClasses(TestJunit.class); for (Failure failure : result.getFailures()) { System.out.println(failure.toString()); } System.out.println(result.wasSuccessful()); } } Now run the Test Runner which will not run any test case defined in provided Test Case class.
C:JUNIT_WORKSPACE>java TestRunner Verify the output. No test case is tested.
