org.junit.runners.model.InvalidTestClassError: 解决JUnit测试类错误

This error message suggests that the test class "com.timevale.doccooperation.service.impl.FlowTemplateServiceTest" is invalid. There could be several reasons why the test class is considered invalid: \n\n1. The test class may not have a public constructor: JUnit requires test classes to have a public constructor without any arguments. If the test class does not have a public constructor, this error will be thrown. \n\n2. The test class may be abstract: JUnit does not allow abstract test classes. If the test class is declared as abstract, this error will be thrown. \n\n3. The test class may not be a static inner class: JUnit requires test classes to be either top-level classes or static inner classes. If the test class is a non-static inner class, this error will be thrown. \n\n4. The test class may not be public: JUnit requires test classes to be public. If the test class is not declared as public, this error will be thrown. \n\nTo resolve this error, you can check if any of the above conditions are true for the test class "com.timevale.doccooperation.service.impl.FlowTemplateServiceTest" and make the necessary changes to ensure that the test class is valid.
