毕业设计&课设-一个JUnit5扩展，用于帮助编写调用System.exit（）的测试.zip

# JUnit5 System.exit() Extension This [JUnit 5 Extension](https://junit.org/junit5/docs/current/user-guide/#extensions) helps you write tests for code that calls `System.exit()`. Starting with JUnit 5, @Rules, @ClassRules, and Runners were replaced by the Extension concept. ## Installing Copy the following into your `build.gradle` or `build.xml`. **Gradle** ```groovy testImplementation("com.ginsberg:junit5-system-exit:1.1.2") ``` **Maven** ```xml <dependency> <groupId>com.ginsberg</groupId> <artifactId>junit5-system-exit</artifactId> <version>1.1.2</version> <scope>test</scope> </dependency> ``` ## Use cases **A Test that expects `System.exit()` to be called, with any status code:** ```java public class MyTestCases { @Test @ExpectSystemExit public void thatSystemExitIsCalled() { System.exit(1); } } ``` **A Test that expects `System.exit(1)` to be called, with a specific status code:** ```java public class MyTestCases { @Test @ExpectSystemExitWithStatus(1) public void thatSystemExitIsCalled() { System.exit(1); } } ``` **A Test that should not expect `System.exit(1)` to be called, and fails the test if it does:** ```java public class MyTestCases { @Test @FailOnSystemExit public void thisTestWillFail() { System.exit(1); } } ``` The `@ExpectSystemExit`, `@ExpectSystemExitWithStatus`, and `@FailOnSystemExit` annotations can be applied to methods, classes, or annotations (to act as meta-annotations). ## Contributing and Issues Please feel free to file issues for change requests or bugs.
