Gradle找不到JUnit测试

Question

在Java中，我有以下测试：

import org.junit.jupiter.api.Test;

import static org.junit.jupiter.api.Assertions.*;

abstract class MyClassTest {
    @Test
    static void testTwoPlusTwoIsFour() {
        assertEquals(4, 2 + 2);
    }

    @Test
    static void testMinusOneThatsThree() {
        assertEquals(3, -1);
    }
}

运行gradle build会给我以下输出：

Test run finished after 95 ms
        [         1 containers found      ]
        [         0 containers skipped    ]
        [         1 containers started    ]
        [         0 containers aborted    ]
        [         1 containers successful ]
        [         0 containers failed     ]
        [         0 tests found           ]
        [         0 tests skipped         ]
        [         0 tests started         ]
        [         0 tests aborted         ]
        [         0 tests successful      ]
        [         0 tests failed          ]

Gradle似乎无法在我拥有的任何测试类中找到任何测试。

Answer 1

事实证明，

Gradle无法找到static，private或abstract类的测试。

以下方法访问修饰符对测试方法有效：

• package-private（无修饰符）
• protected
• public

以下类访问修饰符对测试类有效：

• package-private（无修饰符）
• public

以下关键字不对测试有效：

• abstract
• static
• private

只需从测试中移除abstract和static关键字即可解决所有问题：

import org.junit.jupiter.api.Test;

import static org.junit.jupiter.api.Assertions.*;

class MyClassTest {
    @Test
    void testTwoPlusTwoIsFour() {
        assertEquals(4, 2 + 2);
    }

    @Test
    void testMinusOneThatsThree() {
        assertEquals(3, -1);
    }
}

Gradle输出：

Test run finished after 158 ms
        [         2 containers found      ]
        [         0 containers skipped    ]
        [         2 containers started    ]
        [         0 containers aborted    ]
        [         2 containers successful ]
        [         0 containers failed     ]
        [         2 tests found           ]
        [         0 tests skipped         ]
        [         2 tests started         ]
        [         0 tests aborted         ]
        [         1 tests successful      ]
        [         1 tests failed          ]
