Experiment Requirements
- You should be familiar with Junit Test or Unittest and the usage of these tools.Such as ‘assert, suite, timeout’, check problems for detail.
- Fix the missing codes according to requirement for every problem.
Aim
Learn related knowledge about Junit Test for Java and Unittest for python to do the Softeware Testing.
