我有一个测试类，其中有我的Java项目的所有测试用例，我想一次初始化服务类，它创建一个数组，并且我想对所有其他测试用例使用相同的数组，这样做，但是当第一个测试用例运行时，将客户注册并存储在数组中，我想使用存储在数组中的客户并将其用于下一个测试用例，但看来客户不在数组中下一个测试用例，即正在创建一个新数组，或者我认为junit会分别运行每个测试用例

要解决您的问题，您首先需要了解JUnit行为。
@BeforeClass和@AfterClass的方法仅运行
一次，是您所有测试方法的上限和下限。@Before和@After的方法将立即运行
在任何测试方法之前和之后。还请注意，作为单元测试的规则，所有测试（所有测试方法）都必须相互隔离，但是在集成测试中可以。
