Record to solve the error about junit use

Record the use of Junit to report errors and solutions

(1)Test is not an annotation type

I won't say much about the error description. Tell me about the background of my environment so that I can better record the scene where this problem occurs. I recently learned about shiro, because of the work requirements, to test a piece of code, so I created a small project named Test class, the previous test was executed using the main method without any problems.

Today, I want to test the permission function of shiro, and I want to use Junit to test it. I was lazy and added a method to the Test class to test, and the result reported the following error:

At first glance, it shouldn't be, JAR is dripping. Later, I found that the name of the Test class created is the same as the name of the annotation @Test.

Solution:

The class name of the test cannot be the same as @Test

 

(2)junit.framework.AssertionFailedError: No tests found in xxxxx

The test code is as follows:

 

The error message at runtime is as follows:

junit.framework.AssertionFailedError: No tests found in com.stydy.shiro.TestShiro

	at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192)

 The reason is that the red words in the picture indicate that the first letter of the method is capitalized.

Solution:

Capitalize and lowercase method
