Order Processing Testing – Moq 4 and xUnit

I am reading, experimenting and hopefully learning how to use Moq is a mocking framework for C#/.NET. To learn more about mocking objects read here. For additional documentation on moq4 read here.

After completing the PluralSight course “Mocking with Moq 4 and xUnit” I decided to look for examples of Moq mocking a database. This post is based on my experience and comments on the article Unit Test Through Mocking Using MOQ Framework by Chinmay Dey published Dec 26, 2018.

Calculator in C#

In this post we will develop a simple calculator able to add, subtract, multiply and divide.

The code will be implemented in C# using Visual Studio 2022.

Once we have the main code operational, we will add xUnit and will test using Moq4.

Let’s start by showing some output from our simple calculator. Continue reading “Calculator in C#”

Longest Absolute File Path – C# and Java – Revisited

Hope you had a nice Thanksgiving day with family and friends. My wife and I typically roast a turkey. This year, for the first time, we went with a fresh turkey breast. It was a fraction of the weight of a full turkey and when all was said and done, my wife did not have to deal with cleaning the bones. Today, and probably for the next few days, we will be having different types of turkey sandwiches (Bread, butter on the outside, panini press @ 350F, turkey meat. When brown and crunchy, open sandwich, apply mayonnaise and a touch of mustard. Close and enjoy).

In this post I will revisit solving LeetCode 388. Longest Absolute File Path. The motivation was a message I received a few days back on a solution in O(n). I looked up my solution in Java from February 27, 2017 and it was hard to follow. At the time I used a different plugin and the output was not that great. With time it stopped working so I switched to a different one. Much better but sometimes it mangles the output. Continue reading “Longest Absolute File Path – C# and Java – Revisited”

LeetCode 169 Majority Element in Java

In this post we will attempt to solve LeetCode 169. Majority Element problem using Java.

Given an array nums of size n, return the majority element.

The majority element is the element that appears more than floor(n / 2) times. 
You may assume that the majority element always exists in the array.

Constraints:

o n == nums.length
o 1 <= n <= 5 * 10^4
o -2^31 <= nums[i] <= 2^31 - 1

o Array
o Hash Table
o Divide and Conquer
o Sorting
o Counting

We are given an int[] array and we must return the majority element. There are several variations of this problem. I believe we have solved a couple in this post. Continue reading “LeetCode 169 Majority Element in Java”
