Agnostic Test

Run tests in VSCode across different languages with Zero Configuration®.

Agnostic Test is a spiritual sibling to test.vim. When I moved to VS Code, I missed my zero-configuration test runner that allowed for swapping languages while maintaining the same key mappings for running tests.

VS Test is most similar to what I was looking for, but the project looked abandoned (and unpublished on the extensions directory), so Agnostic Test was born.

Commands

• Run test under cursor - If you're in a test file, run the test under the cursor
• Run test file - Run all tests within the file
• Run test suite - Run the full test suite
• Run previous test - Run the previous test. Handy for TDD when editing a file outside of your test file.

Keybindings

Similar to VS Test, if you are looking for the functionality of vim.test and are using the Vim extension, add the following to your settings.json (I will use <leader> as a designation for your leader key; replace <leader> with your actual leader key):

// ...
"vim.normalModeKeyBindingsNonRecursive": [
    {
        "before": ["<leader>", "t"],
        "commands": ["agnostic-test.runFocusedTest"]
    },
    {
        "before": ["<leader>", "T"],
        "commands": ["agnostic-test.runCurrentTestFile"]
    },
    {
        "before": ["<leader>", "a"],
        "commands": ["agnostic-test.runTestSuite"]
    },
    {
        "before": ["<leader>", "g"],
        "commands": ["agnostic-test.runPreviousTest"]
    },
],
// ...

Global configuration

You can customize the commands run for specific test runners. This is handy if, for instance, you would like to run a global test runner instead of a project-specific instance installed via a package manager.

Here are the currently available configuration options (settings should be added to your editor's settings.json file):

{
    "agnostic-test.php.pest.command": null,
    "agnostic-test.php.phpunit.command": null,
    "agnostic-test.javascript.jest.command": null,
    "agnostic-test.javascript.mocha.command": null,
    "agnostic-test.javascript.cypress.command": null,
    "agnostic-test.elixir.exunit.command": null
}

Project-specific configuration

For some projects, you may wish to have a different configuration that does not interfere with your global configuration. For example, projects using Docker may need additional configuration to get your test runner working within a Docker container.

In cases such as these, a project-specific configuration can be used to overload global configuration defaults.

Create a .testrc.json file in the root of your directory with the following contents:

{
    "php": {
        "pest": {
            "command": null
        },
        "phpunit": {
            "command": null
        }
    },

    "javascript": {
        "jest": {
            "command": null
        },
        "mocha": {
            "command": null
        },
        "cypress": {
            "command": null
        }
    },

    "elixir": {
        "exunit": {
            "command": null
        }
    }
}

Notes for this file:

• Add this file your .gitignore
• Any languages that you do not use can be omitted

Running in the commands manually

If you are using the extension and do not want to set up keybindings, you will need to run the commands manually. To do so:

• Press Ctrl + Shift + P
• Begin a search for "Agnostic Test"
• Select the desired command from the dropdown selection

Currently Supported Testing Frameworks

Pull requests are welcome for new languages or frameworks. Due to limited familiarity with other languages, it is preferred that any new language support also comes with test coverage.

At the moment, the following languages are supported:

PHP

• PHPUnit
• Pest

JavaScript

• Cypress - If a test runner encounters the string cy. in the test file, it will run Cypress tests.
• Jest
• Mocha

Elixir

• ExUnit

Requirements

This extension does not have any dependencies; however, the framework you are utilizing for testing likely will. Please refer to the documentation for your test framework for installation within your project.

Expectations

Although there are configuration options for Agnostic Test, there are still assumptions it makes when running test commands in your project. It expects:

• Your VSCode workspace is the root of the project
• Your file name, and secondly, your package manager's dependencies, are enough to determine the test being run
• You are only using one testing framework for the same file type. So, for example: if you use both Mocha and Jest in a JavaScript project, Agnostic Test will have trouble distinguishing which test runner to use for any .js extensions.

Runner-specific Issues

Cypress

• It is difficult to tell if an entire suite should be run with the Cypress runner. This could be done by testing that the file path of the suite is in the /cypress folder, but I'm personally not a fan of that convention, and I think it's going a bit too far in the "convention over configuration" route.
