问题

我有一个测试类和其中的三个测试方法。问题是，当我运行测试时，具有@Test注解的方法不按它们在类中的顺序运行，首先运行getWorkPlanWhenNotReady()，然后是isWorkPlanReady()，最后运行loginIsSuccessfull()。我希望测试方法按它们在类中的顺序运行，任何帮助将不胜感激。这是我的测试类：

希望这可以帮助您按顺序运行测试方法。

i have a test class and three test methods in it. problem is that when i run test, methods having @test annotation doest run in sequence they placed in class, first getWorkPlanWhenNotReady() runs then isWorkPlanReady() and last loginIsSuccessfull() runs. i want test methods run in sequence they placed in class , any help will be appereciated this is my test class:

我通过在这个链接中找到的描述解决了这个问题：
按特定顺序运行测试

因为我使用JUnit运行器来运行测试，并使用以下注解来运行测试：
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
并且将方法命名为所需的按字母顺序的名称解决了这个问题。

英文:

i resolved problem by finding a description in this link :
Running your tests in a specific order

and cause i use junit ruuner to run test this annotation :
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
and naming methods with desired alphabetical names solved the problem
