Go Test Mocking

The accompanying code repo for the Golang Testing: Mocking and Error Handling article.

This repository contains:

1. maintenance package for the acting third-party dependency package
2. maintenance_test package for the related tests for the mainatenance package
3. vehicle package for the target or in-development package
4. vehicle_test package for the related tests for the vehicle package
5. main package

Background

The accompanying code repo for the Golang Testing: Mocking and Error Handling article.

There are two branches used for the demo:

• The (main branch) contains mocks, interfaces, and receiver functions where vehicle package is decoupled from the maintenance package. https://github.com/williaminfante/go_test_mocking
• The (no-mocks branch) does NOT consider mocks, interfaces, and receiver functions where vehicle package is coupled with the maintenance package. https://github.com/williaminfante/go_test_mocking/tree/no-mocks Please note that this is not the recommended way and was only created for learning purposes.

Usage

This requires a minimum version of Go 1.16 and testify 1.7.0.

You can also just execute:

go mod tidy

To run all tests and optionally add -v for verbose, you can just run the following the base repo path:

go test ./... -v

Or go to the folder like the maintenance folder and run

go test -v

To check coverage to the desired output like cover.out in the coverage for all tests, simply:

go test ./... -v -short -coverprofile coverage/cover.out

To create an html-formatted coverage document:

go tool cover -html=coverage/cover.out -o coverage/cover.html
