根因分析

在每次方法生命周期的测试类中，@BeforeAll 或 @AfterAll 方法不是静态的。

English

@BeforeAll or @AfterAll methods are not static in a per-method lifecycle test class.

generic

解决方案

  1. 90% 成功率 Make method static 
    @BeforeAll
static void setUp() {
    // static setup
}
  2. 85% 成功率 Use @TestInstance(Lifecycle.PER_CLASS) 
    @TestInstance(Lifecycle.PER_CLASS)
class MyTest {
    @BeforeAll
    void setUp() {
        // non-static setup
    }
}

无效尝试

常见但无效的做法:

  1. Adding static keyword without changing method logic 60% 失败

    Method may access instance fields which are not allowed.

  2. Removing @BeforeAll annotation 70% 失败

    Setup logic won't run, causing test failures.
