Code coverage is the way of determining how much of the code is actually covered through the tests. This metric is extremely useful in determining what other tests need to be written. This post will explore code coverage in Golang. What is code coverage? Code coverage is the way to determine the test coverage of […]

Go offers benchmarking via the testing package. In this post, we will try doing simple benchmarks to see how it works. What is a Benchmark? A benchmark by the dictionary definition is a standard, with which the same type of things may be compared. In programming, benchmark tests the time of execution for an operation.

Unit testing is essential when creating software. It tests each component one after another but does not test it entirely. In this post, we will use the testing package to do some unit testing in Go. What is testing? Testing is when we want to check the correctness of our code. It’s a really important

Go has support for first-class functions, which means the functions can be used pretty much everywhere. This creates a new property for the function to become aware of its surroundings. This property is called the closure property. What is Closure in Golang? Closure occurs when an anonymous function in Go has access to its surroundings.

Reflection is an advanced programming concept, which in some programming languages allows the program to check types and values at runtime. Go has a package for reflection – the reflect package. In this post, we are going to discuss how to do reflection in Go. What is Reflection in Programming? Reflection is the way a

Go has a built-in package for reading and writing CSV files. This post will cover the necessary details for working with CSV files in Golang. What is a CSV File? CSV is an encoding which stands for Comma Separated Values. This encoding delimits the data using commas. It is one of the most used encodings

The time package contains everything useful about time. In this post, we are going to explore the time package in Go. The Sleep() function in time package First, we need to import the time package to do something with it. The time package has a sleep function that can pause the main Go thread. The

Packages allow us to focus on the code reuse principle aka the DRY (Don’t Repeat Yourself) principle. It enables us to write concise code in a structured manner. In this post, we are going to take a look at the package system in Go. What is a package in Go? A package is essentially a

Go has no apparent “pointer to a function” but it can store the functions and call it later making the function pointers implicitly defined. What is a function pointer? In some programming languages like C/C++, there can be a pointer that can store the address of a function and later call it using itself. This

We can replace characters in a String using the Golang library functions. This post will focus on library functions and what other options available for string replacement in Go. Can we use direct assignment to replace String Contents? When we have a string and we directly want to assign values at different index, the function
