Golang advanced tutorial

Welcome fellow coders!

In this tutorial, we are going to be taking a look at selection of more advanced testing practices used by the likes of the Go core language developers and in popular production-level tools. I feel this approach, of actually studying what has been done in a production system, will hopefully give you some insight into the best ways to test your own production-level Go programs. Note - If you are entirely new to testing your Go-based programs, then I suggest you check out my other tutorial: an introduction to testing in go.

For example, take a look at lastIndexTests which is an array of type IndexTest :. This array is used to test the LastIndex function within the strings.

Each of these IndexTest elements feature a standard stringa separator, and an out integer value and have a struct that looks like this:. These tests are then triggered by the TestLastIndex function which runs through all of these test cases and checks to see whether the results returned from the lastIndex function match the expected results outlined in the array. This same practice is done numerous times for numerous different functions and this helps to guarantee that when any code changes are made to these functions, the expected functionality will not change.

If this is the case then one option is to create a testdata directory and store any files you may need for testing within that directory. In the above test case, we basically overwrite the response we expect from our URL and then continue to test other parts of our system that rely upon that response.

The reason for this? It helps you to avoid cyclic imports. If the package you import in already has a reference to the package you are trying to test, you may see issues with cyclic dependencies. So, in this tutorial, we had a look at some of the more advanced testing techniques and tricks employed by the Go language maintainers. Hopefully, you found this useful and it gave you the insight needed to go off and improve your own go tests.

But they launched it in as an open-source programming language. It provides a rich standard library, garbage collection, and dynamic-typing capability and also provides support for the environment adopting patterns alike to dynamic languages. The latest version of the Golang is 1. Here, we are providing a complete tutorial of Golang with proper examples.

The main purpose of designing Golang was to eliminate the problems of existing languages. Before we begin with the installation of Go, it is good to check if it might be already installed on your System. Before starting with the installation process, you need to download it. For that, all versions of Go for Windows are available on golang. Download the Golang according to your system architecture and follow the further instructions for the installation of Golang.

Step 1: After downloading, unzip the downloaded archive file. After unzipping you will get a folder named go in the current directory. Step 2: Now copy and paste the extracted folder wherever you want to install this.

Here we are installing in C drive. Step 3: Now set the environment variables. Right click on My PC and select Properties. Choose the Advanced System Settings from the left side and click on Environment Variables as shown in the below screenshots. Step 4: Click on Path from the system variables and then click Edit. Then Click New and then add the Path with bin directory where you have pasted the Go folder.

Step 5: Now create a new user variable which tells Go command where Golang libraries are present. For that click on New on User Variables as shown in the below screenshots.When you start becoming proficient with the main programming languages, it can be tough to find one that would bring you the same inspiration as when you had just started programming.

Now you might be thinking - why do I even need to learn GO? What's in this GO language tutorial for me? Golang was developed by the team at Google and is very similar to the C programming language. However, as you learn GO in this Golang tutorial, you will quickly see how many added features this programming language has when compared to C - a safe memory, garbage collection and so on!

All of these features add up and make GO an increasingly popular programming language among experienced programmers and developers.

This course was born out of that struggle - I aim to make the learning experience as pleasant as it can possibly be when you learn Golang. This GO tutorial will teach you about the GO syntax, concurrency models, packages and much more - all in a fluid and straightforward way!

Whether you want to learn about critical design decisions and apply them to get a raise at your job, or simply want to add another programming language to your ever-growing skillset - this course will have you covered!

As for the GO tutorial requirements - you should be quite proficient and have decent experience with other programming languages. The best choices would be Java, Python, Ruby and other similar ones. Since this course is aimed at people who want some advanced information and insight into Golang and all of its great features, you have to have decent experience with other programming languages to be able to understand the terminology and processes used here.

Golang can be viewed as the Python of statically-typed languages.

The approach to learning Golang is just like the approach followed for any other programming language i. To get started with the programming language, you can also follow the official Go tour.

Unlike most programming languages, Golang favors software engineering over programming language research. It focuses on conciseness, concurrency, performance, readability, and simplicity. Following are some reasons advocating learning Golang:. Very much like C but with CSP-style concurrency, garbage collection, memory safety, and structural typing. You can learn Golang from Udemy, Coursera, hackr. YouTube is a good place to learn the basics of the programming language and some of its advanced topics.

Golang is a programming language that highly prioritizes simplicity. In fact, it is even simpler than Python, which is considered to be the simplest programming language by many.

The most difficult to learn aspects of Go are concurrency features, channels and goroutines, and interfaces. The simple answer is no. However, both Golang and Python are designed for achieving high concurrency.

Golang can be faster than Python when it comes to building concurrent services. Hence, Golang might soon replace Python as the server-side language for achieving highly concurrent services.

Go Tutorial

Go is designed to be as easy as possible. So, Java is faster than Go due to the following two main reasons:. Golang or Go is an open-source programming language that eases the process of building efficient, reliable, and simple software.

The statically-typed programming language prefers the ease of use over anything else. It was introduced by Google in November of Golang supports concurrency and automatic garbage collection. Also, it has excellent support for error check and is highly scalable. On top of them all, it is very simple and a lightweight, open-source programming language developed and maintained by Google.

Closures - Go Lang Programming Tutorial: Part 15

Go does not require special rules around the code formatting, but have a standard that is generally used and accepted in the community. Golang is quite capable of implementing higher level abstractions, but the language designers choose not to implement certain abstractions into the programming language itself.

You can use interfaces to create common abstraction that can be used by multiple types. Interfaces define one or more method declarations that must be satisfied to be compatible with the interface. CRUD operations are basic data manipulation for database.

In this example, we are going to create an interface as database front end to handle these operations. We have Employee table containing Employee information like id, name and city. If you add a WaitGroup struct to your code, it can delay execution of the main function until after all goroutines are complete. In simple terms, it lets you set a number of required iterations to get a completed response from the goroutines before allowing the application to continue.

Done decrements the WaitGroup counter. Wait blocks until the WaitGroup counter is zero. The bufio package Scanner is a suited for reading the text by lines or words from a file.

In below example you can decode or unmarshal the JSON document into a map variable. The below example is to converts a map type into a JSON string. An instance of catalog struct is created by providing values of the two objects that implemented the Information interface. The objects of Information type, are created with the Mobile type and the Shirts type.
