# Buildkite Collectors for JavaScript
Official [Buildkite Test Engine](https://buildkite.com/platform/test-engine) collectors for JavaScript test frameworks ✨
⚒ **Supported test frameworks:** Jest, Jasmine, Mocha, Cypress, Playwright, Vitest, and [more coming soon](https://github.com/buildkite/test-collector-javascript/issues?q=is%3Aissue+is%3Aopen+label%3A%22test+frameworks%22).
📦 **Supported CI systems:** Buildkite, GitHub Actions, CircleCI, and others via the `BUILDKITE_ANALYTICS_*` environment variables.
## 👉 Installing
1. [Create a test suite](https://buildkite.com/docs/test-engine), and copy the API token that it gives you.
2. Add the [`buildkite-test-collector` package](https://www.npmjs.com/package/buildkite-test-collector):
```bash
# If you use npm:
npm install --save-dev buildkite-test-collector
# or, if you use yarn:
yarn add --dev buildkite-test-collector
```
3. Add the Buildkite test collector to your testing framework:
### Jest
Update your [Jest configuration](https://jestjs.io/docs/configuration):<br>
```js
// jest.config.js
// Send results to Test Engine
reporters: [
'default',
'buildkite-test-collector/jest/reporter'
],
// Enable column + line capture for Test Engine
testLocationInResults: true
```
If you would like to pass in the API token using a custom environment variable, you can do so using the report options.
```js
// jest.config.js
// Send results to Test Engine
reporters: [
"default",
[
"buildkite-test-collector/jest/reporter",
{ token: process.env.CUSTOM_ENV_VAR },
],
];
```
### Vitest
Update your [Vitest configuration](https://vitest.dev/config/):<br>
```js
// vitest.config.js OR vite.config.js
test: {
// Send results to Test Engine
reporters: [
'default',
'buildkite-test-collector/vitest/reporter'
],
// Enable column + line capture for Test Engine
includeTaskLocation: true,
}
```
If you would like to pass in the API token using a custom environment variable, you can do so using the report options.
```js
// vitest.config.js OR vite.config.js
test: {
// Send results to Test Engine
reporters: [
'default',
[
"buildkite-test-collector/vitest/reporter",
{ token: process.env.CUSTOM_ENV_VAR },
],
],
}
```
### Jasmine
[Add the Buildkite reporter to Jasmine](https://jasmine.github.io/setup/nodejs.html#reporters):<br>
```js
// SpecHelper.js
var BuildkiteReporter = require("buildkite-test-collector/jasmine/reporter");
var buildkiteReporter = new BuildkiteReporter();
jasmine.getEnv().addReporter(buildkiteReporter);
```
If you would like to pass in the API token using a custom environment variable, you can do so using the report options.
```js
// SpecHelper.js
var buildkiteReporter = new BuildkiteReporter(undefined, {
token: process.env.CUSTOM_ENV_VAR,
});
```
### Mocha
[Install mocha-multi-reporters](https://github.com/stanleyhlng/mocha-multi-reporters) in your project:<br>
```
npm install mocha-multi-reporters --save-dev
```
and configure it to run your desired reporter and the Buildkite reporter
```js
// config.json
{
"reporterEnabled": "spec, buildkite-test-collector/mocha/reporter"
}
```
Now update your test script to use the buildkite reporter via mocha-multi-reporters:
```js
// package.json
"scripts": {
"test": "mocha --reporter mocha-multi-reporters --reporter-options configFile=config.json"
},
```
If you would like to pass in the API token using a custom environment variable, you can do so using the report options.
Since the reporter options are passed in as a json file, we ask you to put the environment variable name as a string value in the `config.json`, which will be retrieved using [dotenv](https://github.com/motdotla/dotenv) in the mocha reporter.
```js
// config.json
{
"reporterEnabled": "spec, buildkite-test-collector/mocha/reporter",
"buildkiteTestCollectorMochaReporterReporterOptions": {
"token_name": "CUSTOM_ENV_VAR_NAME"
}
}
```
### Playwright
Update your [Playwright configuration](https://playwright.dev/docs/test-configuration):<br>
```js
// playwright.config.js
// Send results to Test Engine
reporter: [
['line'],
['buildkite-test-collector/playwright/reporter']
],
```
If you would like to pass in the API token using a custom environment variable, you can do so using the report options.
```js
// jest.config.js
// Send results to Test Engine
reporter: [
['line'],
['buildkite-test-collector/playwright/reporter', { token: process.env.CUSTOM_ENV_VAR },]
],
```
If you would like to pass execution tags through to Test Engine, then you can use Playwright's tagging syntax as follows:
```
test('has tags', { tag: ['@type:feature'] }, ...)
```
This will be threaded through to Test Engine as an execution tag with key set to `type` and value set to `feature`.
### Cypress
Update your [Cypress configuration](https://docs.cypress.io/guides/references/configuration):<br>
```js
// cypress.config.js
// Send results to Test Engine
reporter: "buildkite-test-collector/cypress/reporter",
```
If you would like to pass in the API token using a custom environment variable, you can do so using the reporterOptions.
```js
// cypress.config.js
// Send results to Test Engine
reporterOptions: {
token_name: "CUSTOM_ENV_VAR_NAME"
}
```
4. Run your tests locally:<br>
```js
env BUILDKITE_ANALYTICS_TOKEN=xyz npm test
```
5. Add the `BUILDKITE_ANALYTICS_TOKEN` secret to your CI, push your changes to a branch, and open a pull request 🎉
```bash
git checkout -b add-bk-test-engine
git commit -am "Add Buildkite Test Engine"
git push origin add-bk-test-engine
```
## 📓 Notes
This jest collector uses the [`onRunComplete`](https://jestjs.io/docs/configuration#custom-reporters) hook to report test results to the Buildkite API. This interferes with the [`--forceExit`](https://jestjs.io/docs/cli#--forceexit) CLI option and interrupts the request that sends tests results, meaning that no data will be available for your test suite. It's recommended to use [`--detectOpenHandles`](https://jestjs.io/docs/cli#--detectopenhandles) to find any hanging process and clean them up and remove the use of `--forceExit`.
## 🔍 Debugging
To enable debugging output, set the `BUILDKITE_ANALYTICS_DEBUG_ENABLED` environment variable to `true`.
## 🔜 Roadmap
See the [GitHub 'enhancement' issues](https://github.com/buildkite/test-collector-javascript/issues?q=is%3Aissue+is%3Aopen+label%3Aenhancement) for planned features. Pull requests are always welcome, and we’ll give you feedback and guidance if you choose to contribute 💚
