Junit测试代写 | CSDS 293 Software Craftsmanship Programming Assignment 8

本次美国代写是Junit测试相关的一个assignment

Grading Guidelines

The grade will primarily depend on the process to develop test cases.
High marks will be given to test suite that are developed following
a methodic process.

An automatic C (or less) is triggered by

• Any routine with complexity greater than 4,
• Any substantially repeated piece of code, or by
• Improperly named routines.

However, a submission that avoids these problems does not
necessarily qualify for high quality craftsmanship.

Starting with programming assignment 10, points will be deducted
if code or branch coverage is incomplete.

Programming

Overview

First, make all changes discussed during last week’s code review.
In this assignment, you will design, write, and run test cases in JUnit.
The emphasis is on a methodic and coherent process to develop and
implement test cases. You should avoid developing a test suite in a
generic and haphazard manner. Although it is very tempting to develop
test cases by error guessing, a methodic process has been discussed
in the lectures and reading assignments and should be followed
starting from this assignment. An example is given on canvas under
Modules, Labelled Test Cases, TestDevelopment.pdf.

For each method, the test cases have to exhaust the typology
described in Section 22.3 (not all categories are applicable to all
methods):

• Code coverage
• Branch coverage
• Data-flow (extra credit)
• Boundary
• Compound boundaries
• Bad data
• Good data

Design Document

First, create a separate test design document. The design document
should be modeled after the test development example in canvas.
For each method, define

• Test conditions: each with an identifier, goal, notes, and
conditions (Section “Conditions” in the canvas example.)

• Tests: each with an identifier, identifiers of the satisfied
conditions, and assertions (Section “Tests” in the canvas
example.)

You can omit tests for methods that are automatically generated
(such as some constructors, getters, setters, equals, toString, or
delegate).

Additionally, describe at least one stress test for the whole code base
(Section “Stress Test” in the canvas example and in Code Complete).

Implementation

Second, implement the tests. Add a comment to each test to cross-
reference it with the test design document. The test cases that you
have developed for assignments 6 and 7 should be included and
cross-referenced as “good data (legacy)”.

All methods must be tested individually. All protected and private
methods must be tested individually. In other words, you cannot test
a private or protected method solely by invoking the public methods
that call it. Instead, you need to write test cases that invoke the
private or protected method through a nested test hook. An example
is in the testexample repository that you cloned in assignment 7. You
cannot use reflection to test private and protected methods.

If you plan to skip testing of an automatically generated method, you
should have your IDE generate the method’s documentation
automatically.

Your build environment (build.xml or Makefile) should contain the
following targets:

• “test” target should run all the test cases.
• “report” target should generate a html Junit and JaCoCo
report for the test cases.

During discussion, your leader should be able to run the tests and
display the reports.
