In golang, we have internal function like stat(), Open(0 and Readfile() that is used for checking whether a specific file exist or not. In the first example we are using the stat() method present in the os package while in the second and third example we are using Open() and ReadFile() function respectively. Method 1: Using STAT() Method In this method, we will use the Stat function present in os package to check if the file exists or not. Syntax Stat(file string) The stat() function is present in os package and is used to get the status of ... Read More
System testing is a type of software testing in which a software product is tested as a whole for the validation of its functional and non-functional requirements, whereas integration testing is a testing in which a software product is tested for the interfacing between its different modules that are interlinked with each other. Read this article to learn more about system testing and integration testing and how they are different from each other. What is System Testing? System Testing is a testing which is used to validate the functionality of a software product developed. It is also known as black ... Read More
In Golang, we can use openfile() and Stat() function to check whehter a file has writable permission or not. Here we have written two examples. in the first one we are using OpenFile() method present in the os package while in the second one we are using the Stat() method present in the os package respectively. Method 1: Using OpenFile() Method In this method, we will use the OpenFile() function to check the write permission of a file. This function opens a file with the given name and options, and returns a pointer to a File structure. Syntax func OpenFile(name ... Read More
Testing is a major step for the successful delivery of any application. On the basis of the level of execution of testing, we can classify testing into two categories − System Testing and Acceptance Testing. Read this article to learn more about system testing and acceptance testing and how they are different from each other. What is System Testing? System Testing is a type of testing which is used to validate the functionality of a developed software product. It is also known as black box testing. This testing involves the behavioral as well as functional testing of the software product ... Read More
Syntax defines the rules and regulations that help write any statement in a programming language, while semantics refers to the meaning of the associated line of code in the programming language. Read this article to learn more about syntax and semantics and how they are different from each other. What is Syntax? In a programming language, Syntax defines the rules that govern the structure and arrangement of keywords, symbols, and other elements. Syntax doesn't have any relationship with the meaning of the statement; it is only associated with the grammar and structure of the programming language. A line of ... Read More
In golang we have different inbuild function like Stat(), Open() and mkdir() to check whether a directory exist or not . Here we are using three functions. in the first one we are using the Stat() function present in the os package while in the second and third example we are using Open() and mkdir() function respectively to implement the result. Method 1: Using os.stat() Method The os package provides the Stat() function to get information about a file or directory. If the directory exists, the function returns a FileInfo structure, otherwise, it returns an error. Syntax func ... Read More
Golang provides several methods to remove a specified directory, including using the os and filepath packages. Removing a directory is a critical operation, and caution should be exercised when performing this task. This article will discuss the different methods to remove a directory in Golang, along with the syntax and algorithm for each method. Method 1: Using The os Package The os package in Golang provides several functions to perform operating system-related operations, including removing a directory. The Remove function of the os package is used to remove a directory. Syntax Remove(dirName) The Remove() function is present in os ... Read More
Primarily, there are two types of data types − Primitive and Non-primitive. Primitive data types are predefined types of data, which are supported by the programming language. Non-primitive data types are not defined by the programming language, but are instead created by the programmer. With this brief introduction to data types, let's start this article and differentiate Stack and Queue data structures. Both Stack and Queue are types of data structures to store data in a particular order. A stack data structure is a type of linear list which allows the insertion or deletion of an element ...

In Golang, we have two internal functions - ReadDir() and Walk function to get a list of filenames prenent in a specific directory. Here we have write three examples. In the first example We will use the ReadDir() function present in ioutil package while in the second one we are using the walk function present in the filepath package. Method 1: Using ioutil PACKAGE The ioutil package in Golang provides several functions to perform input/Output operations, including reading the files and directories. The ReadDir() function of the ioutil package is used to get the list of files in a specified ... Read More
The Go programming language provides various methods to obtain the home directory of the current user. This information can be useful in many applications, such as file management, system configuration, etc. In this article, we will discuss different methods to get the home directory in Go along with syntax and examples. Method 1: Using os.UserHomeDir() The os.UserHomeDir() function is part of the Go standard library and is the simplest and most efficient method to get the home directory of the current user. Here is an example that demonstrates the usage of os.UserHomeDir() Syntax func UserHomeDir() (string, error) The UserHomeDir() ... Read More
