JUnit 中的注释列表

2024-02-21

最近在学习并实现JUnit框架。因此，我知道 JUnit 中使用的注释很少：-@Test, @Before, @After, @Ignore, @BeforeClass, @AfterClass, @Runwith(Suite.class), @SuiteClasses({}), @Parameters, @RunWith(Parameterized.class) and @Rule.

我确信 JUnit 中使用了更多注释。任何人都可以指导我列出更多可以使用的注释以及它们在什么情况下使用？

Thanks.

这个 Github 搜索（@interface) 为您提供所有注释的列表：

基本注释

@Test https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/Test.java @Before https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/Before.java @After https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/After.java @AfterClass https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/AfterClass.java @BeforeClass https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/BeforeClass.java @Ignore https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/Ignore.java @Runwith https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/runner/RunWith.java

参数化测试

对于参数化测试使用@Parameters and @RunWith(Parameterized.class)
https://github.com/junit-team/junit/wiki/Parameterized-tests https://github.com/junit-team/junit/wiki/Parameterized-tests

Rules

@Rule https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/Rule.java
规则允许非常灵活地添加或重新定义测试类中每个测试方法的行为。例如创建临时文件夹规则，用于在运行测试时创建临时文件夹。

理论及相关注释

@Theory https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/experimental/theories/Theory.java
理论给出了更灵活和更具表现力的断言

https://github.com/junit-team/junit/wiki/Theories https://github.com/junit-team/junit/wiki/Theories

@DataPoint https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/experimental/theories/DataPoint.java
使用注释字段或方法@DataPoint会导致字段值或该方法返回的值用作潜在参数该课程中的理论

@DataPoints https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/experimental/theories/DataPoints.java

的扩展@Datapoint
使用注释数组或可迭代类型字段或方法@DataPoints将导致数组或可迭代中的值被用作潜在的该类理论的参数

@FromDataPoints https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/experimental/theories/FromDataPoints.java

注释 a 的参数@Theory方法与@FromDataPoints将限制数据点被视为该参数的潜在值@DataPoints与给定的名字

@ParametersSuppliedBy https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/experimental/theories/ParametersSuppliedBy.java
注释一个@Theory方法参数与@ParametersSuppliedBy导致它被提供来自命名的值ParameterSupplier当作为理论运行时

@TestedOn https://github.com/junit-team/junit/blob/master/src/main/java/org/junit/experimental/theories/suppliers/TestedOn.java

The @TestedOn注释采用一组值用作注释的数据点范围。

e.g.

@Theory
public void multiplyIsInverseOfDivideWithInlineDataPoints(
        @TestedOn(ints = {0, 5, 10}) int amount,
        @TestedOn(ints = {0, 1, 2}) int m
) {
    assumeThat(m, not(0));
    assertThat(new Dollar(amount).times(m).divideBy(m).getAmount(), is(amount));
}
