# New: Modules Continuous Integration Testing
> Run automated tests against Terraform modules in the env zero Private Module Registry using OpenTofu test files, triggered on merges and pull requests.
env zero now offers beta support for continuous integration testing for modules. Built on the OpenTofu testing feature, you can set up testing and integrate it into your private module registry.
## Run module CI with OpenTofu tests
Start by creating your [tftest files](https://opentofu.org/docs/cli/commands/test/#testing-modules) and storing them within your module directory. You'll be able to run common tests on a real infrastructure that is created, tested and destroyed in a single flow.
```hcl theme={null}
Run "test" {
Assert {
Condition = file(local_file.test.filename) == "Hello world!"
Error_message = "Incorrect content in ${local_file.test.filename}."
}
}
```
You can write multiple runs in each file, and create multiple test files. env0 will execute all of the tests in all of the files.
## Trigger and manage module tests in your module registry
With your test files in place, enable Testing in your module settings and env0 will trigger test runs on every merge to your default branch (and optionally on every PR targeting the main branch). env0 will then present the test results and a full history of all test runs.
Status checks will be presented in your VCS to give you all the information directly in your flow.
