This case is an entry-level unit test case about creating a triangle, in netbeansEnvironment to build phpunit will not be described here. You can refer to the following information to complete the construction work:

}

It should be noted here that the test file class generated after we execute "Create/Update Test" will be somewhat different from the above. The test cases here are added manually. You can check the instructions in the manual for the specific implementation!

Attached is the execution result:
