Using gtest

gtest simulates a real network by providing mockups of the user, program, balances, mailbox, etc. Since it does not include parts of the actual blockchain, it is fast and lightweight. But being a model of the blockchain network, gtest cannot be a complete reflection of the latter.

As stated earlier, gtest is excellent for unit and integration testing. It is also helpful for debugging Program on Vara logic. Nothing other than the Rust compiler is required for running tests based on gtest. It is predictable and robust when used in continuous integration.

Import gtest lib

To use the gtest library, you must import it into your Cargo.toml file in the [dev-dependencies] block to fetch and compile it for tests only:

Cargo.toml

[package]
name = "first-gear-app"
version = "0.1.0"
authors = ["Your Name"]
edition = "2021"

[dependencies]
gstd = { git = "https://github.com/gear-tech/gear.git", tag = "v1.4.1" }

[build-dependencies]
gear-wasm-builder = { git = "https://github.com/gear-tech/gear.git", tag = "v1.4.1" }

[dev-dependencies]
gtest = { git = "https://github.com/gear-tech/gear.git", tag = "v1.4.1" }
