Testing is a critical aspect of software development, ensuring code reliability, maintainability, and performance. In the Golang ecosystem, a variety of testing frameworks have emerged, each offering unique features and capabilities that cater to different needs. As a backend engineer…
Additional test packages Test files can declare an additional test package, matching the source files package with _test appended. Using the dedicated test package brings the following advantages:1. Prevents brittle tests: Restricting access to only exported functionality does not give…
Types of automated tests Automated testing suites involve tools and frameworks to verify the behavior of software systems. They provide a repeatable way of verifying system requirements. We divide them into several types of tests according to three criteria: System…
Every program is a set of instructions, whether it’s to add two numbers or send a request over the internet. Compilers and interpreters take human-readable code and convert it to computer-readable machine code. https://www.freecodecamp.org/news/compiled-versus-interpreted-languages/ Compiler Compilers will translate developers’s whole…
What Is Bytecode? Bytecode (also called portable code or p-code[citation needed]) is a form of instruction set designed for efficient execution by a software interpreter. The name bytecode stems from instruction sets that have one-byte opcodes followed by optional parameters. It’s not readable by a human programmer like source…
Recover is a built-in function that regains control of a panicking goroutine. If the current goroutine is panicking, a call to recover will capture the value given to panic and resume normal execution. Recover is only useful inside deferred functions. During…
The purpose of functions and subroutines is to save time and space by just calling a function/subroutine. Subroutines do not return any values, while functions return values. Subroutines are also allowed to change the values of the parameters while functions are supposed…
Ownership of ether by EOAs is established through digital private keys, Ethereum addresses, and digital signatures.Account addresses are derived directly from private keys: a private key uniquely determines a single Ethereum address, also known as an account.Ethereum transactions require a…
Ether Currency Units Ethereum’s currency unit is called etherEther is subdivided into smaller units, down to the smallest unit possible, which is named wei. One ether is 1 quintillion wei (1 * 10^18 or 1,000,000,000,000,000,000).When you transact 1 ether, the transaction encodes 1000000000000000000…
What Is Ethereum Ethereum is a deterministic but practically unbounded state machine, consisting of a globally accessible singleton state and a virtual machine that applies changes to that state. Ethereum vs Bitcoin Bitcoin’s blockchain, tracks the state of units of…
