Jest-Runner-Go

Go runner for Jest

Usage

Install

Install jest version 21 or above and jest-runner-go:

With Yarn

 
yarn add -D jest jest-runner-go

With NPM

npm install --save-dev jest jest-runner-go

Add it to your project

Add the following to your package.json

"jest": {
    "moduleFileExtensions": [
      "go"
    ],
    "runner": "jest-runner-go",
    "testMatch": [
      "**/?(*_)test.go"
    ]
},

Or to your jest.config.js

module.exports = {
  runner: 'jest-runner-go',
  moduleFileExtensions: ["go"],
  testMatch: ['**/?(*_)test.go'],
};

Then simply run Jest

yarn jest

Contribute

1. git pull git@github.com:MaximeHeckel/jest-runner-go.git (preferably in your GOPATH if you want to run the examples on your machine)
2. Run npm install or yarn to install the dependencies of the project
3. To build the project run yarn build
4. To run the tests (unit and integration) yarn test or you can also run them using Docker with the Dockerfile provided in this project:

   docker build -t jest-runner-go .
   docker run jest-runner-go

5. To run the example cd example && yarn test or you can also run it using Docker by running this command

   docker run -it jest-runner-go sh -c "cd example && yarn test"

If you want to test your development version of jest-runner-go on another project do the following:

1. In the jest-runner-gofolder run yarn build && yarn link
2. In your other projects run yarn link jest-runner-go

Your project will now use your local jest-runner-go.

Known issues

Duplicated test failure (minor)

When a package contains multiple tests files, if one of them is failing, the error is reported multiple times, (as many times as their are test files in the package). This is due to a conflict between the way Jest and Go define what a failing test is and how they report it: for Jest it's per file, for Go per package.
