Goals and Requirements

• Unit Test Training (JUnit framework app)

• Design method of test case

Requirements:

• [ must do 1] for the triangle given in Appendix 1 to Judge Java code, the use of equivalent class partitioning method to design test cases, tabular form of the design of the test cases, written to the blog. (10 points)

Test Cases
Serial number	Test input: Three edges (a,b,c)	Test Prophecy (Oracle: Right angle, isosceles, equilateral triangle)
1	Input (1,1,1)	Equilateral triangle
2	Input (* * *)	***

• [ must do 2] imitate Appendix 2 gives the triangle judgment junit test Code, Design Unit test script, test [ must do 1] design of the test case. Note the order in which the test cases appear in the test script is consistent with the order listed in the [ required title 1] table. Run the resulting test script, truncate the result graph, write to the blog, and commit the source code to your own github. (20 points)

• [ must do title 3] experience. Write down the Knowledge points (PS: Test Case design methods and steps; test script design steps or main content) that you gain from this exercise. (10 points)

• [ must do title 3] experience. Write down the points of knowledge you have gained from this practice.

In designing test cases, equivalence partitioning can be divided into four categories: non-triangular, general triangular, isosceles triangle, and equilateral triangle. When designing test data, be aware of some special data testing. Data Basic determination process: whether the edge length is within the value range, the third side is less than the sum of the two sides is greater than the difference between, whether it is equilateral isosceles. and learned how to use JUnit.
