Manual Configuration Required
This MCP server requires manual configuration. Run the command below to open your configuration file:
npx mcpbar@latest edit -c claude
This will open your configuration file where you can add the Test Gru MCP server manually.
Forget about Unit Test, you get covered automatically.
This is the example repo for Test Gru. Test Gru will help you add unit test automatically. Here is the video to show how Test Gru works.
Test gru is still in testing phase. If you have any question, please connect to us: [email protected],or join our discord.
Currently, Test Gru only supports Node.js/TypeStript. We are gradually adding support for other languages.
Creat Test Gru Account
Log in at Gru.ai. Test Gru currently only supports use with GitHub accounts. You need a GitHub account to log in to gru.ai.
Enter Test Gru
Click the top left corner to select Test Gru.
Install Github Application
Follow the steps to install Test Gru.
Then select a repo, perform the configuration.
Use Example For Quick Start
- Fork this repo
- Install App and get configuration from code repo
- dispatch src/user.ts
- Test Gru submits a PR
grutest.yaml
Configuration file example
version: "0.1"
global:
setup:
- npm install
pipeline:
runTest:
// If your project uses ESLint and Prettier, you can configure the pre-stage here.
// pre:
// - npx eslint --fix {{sourceFilePath}}
// - npx prettier {{sourceFilePath}} --write
exec:
- npx vitest run {{testFilePath}}
// If your project has certain requirements for the final submitted code, you can configure the post-stage here.
// post:
// - npm run lint
// - npx tsc --noEmit
settings:
// IF you allow TestGru to add export to your source code classes or functions when it needs to test your source code
exportFunctionOrClass: allow
// Location of the source code project
include:
- src
// Location of the test files
testPlacementStrategies:
- type: co-located
testFilePattern: "{{sourceFileName}}.spec.ts"

About testPlacementStrategies
There are two main ways to organize test code.
centralized
If your project structure is as follows:
{% highlight TXT %} . ├── package.json ├── src │ └── sum.ts └── test └── sum.test.ts {% endhighlight %}
then you can configure testPlacementStrategies
like this
{% highlight YAML %}
testPlacementStrategies:
- type: centralized testDir: test testFilePattern: "{{sourceFileName}}.test.ts" {% endhighlight %}
co-located
If your project structure is as follows: {% highlight TXT %} . ├── package.json └── src ├── sum.test.ts └── sum.ts {% endhighlight %}
then you can configure testPlacementStrategies
like this
{% highlight YAML %} testPlacementStrategies: - type: co-located testFilePattern: "{{sourceFileName}}.test.ts" {% endhighlight %}
Trigger Test Gru to work
Auto Rrigger by Pull Request
When you complete the configuration, Test Gru will automatically take over your repository. Whenever you submit a PR, Test Gru will automatically detect software that requires unit tests and add tests for it.
After Gru completes writing the test code, it will run the tests. Once it confirms there are no issues with the test code, it will submit a PR with the unit test code to the current PR.
Manual Trigger
You can manually trigger Test Gru on the Gru.ai.
It can be triggered by PR or existing code files.
