We will use the inbuilt sort package to sort the array in the Go language instead of manually writing any sorting algorithms like merge sort or quick sort, etc. In this post, we will be looking at how we can sort the array of different types like int, float64, etc., in ascending and descending order. […]

This post will discuss how to read a file in Golang. We will use the below packages to work with the files. os package provides a platform-independent interface to perform the operating level operations. ioutil package provides easy-to-use utility functions to work with files without knowing much about the internal implementations. bufio package implements buffered

An array is a data structure used to store similar elements at contiguous memory locations. What we meant by contiguous memory location is that the elements will be present next to each other in the memory and not at random places. So, it is easy to get to the desired element from any element by directly

Functions contain a set of statements bundled together to achieve a particular outcome. Now, a function may call other functions based on its requirements. But, why do we need functions? There are many reasons to use functions in a program. It helps in the reusability of the code because now we don’t have to rewrite

A Pointer is a variable that stores the address of any other variable. We can get the address of the variables by using the & ( an ampersand ) operator, which is also Go’s address of operator. And why do we need pointers? It is a manual overhead to remember the address where the variable

Did you know that TestNG offers a great feature that allows us to define annotations at the class level instead of just the method level? In this post, we will discuss class-level annotations in detail. Let’s say we have 100 methods in one class, and writing the @Test annotation on each of these methods could be quite

In this post, we will be discussing how to use the method interceptors in TestNG. TestNG runs our test cases in alphabetical order of their method names. If TestNG has decided the order in which the test methods will be invoked, then we can split it into two groups – The method runs in a

In this post, we will look at how we can prioritize our test cases using TestNG so that some cases can execute before others. TestNG provides us with a priority attribute to help us achieve just that. We are going to look at the below points. Run test cases with no priority ( In what

Go programming language provides a way to execute a code block repeatedly using the for loop statement. In Go, for loops can be used in several ways, making it a versatile and powerful feature for developers. This article will review the various forms of for loops in Go and how to use them effectively. Loop

In this post, we will be looking at different ways of converting a string object into a double value. In some of the methods listed below, we will be converting the string object into the Double wrapper class object and then using the unboxing feature of Java, that Double class object will be converted into
