This repository provides E2E integration tests for the Theia Cloud IDE. It uses Playwright to simulate real world usage of Online IDE's in large classroom settings.

Information

Tests are written using Playwright
Scaled tests run via the Playwright Artillery Framework or natively only using Playwright
Make sure, that Sessions per User and max instanecs per App Definition is high enough set on the cluster!

Setup

Setup Envionment Variables
- Duplicate playwright.env.template and rename it to playwright.env (make sure this file is gitignored!)
- Fill in the given variables as described in the file, notice:
  - Keycloak User and Password needs to have access to Theia (does not need to be the same Artemis User as of now)
  - Landing Page URL is the URL of the Theia Deployment to test against (this does not affect the Artemis Integration test, as the target deployment is set by Artemis)
  - The Artemis User needs to have enough priviliges to create a course and exercise on the given test server
Get the latest Theia IDE image from here and run it. Put the corresponding URL into the env file
Install dependencies and playwright browser
```
npm install
```
```
npx playwright install
```

Run Tests

To run the functional tests on the deployed Theia instance, run:
```
npx playwright test --project=functional
```
To run tests locally using a Theia Instance on localhost, change the environment variable to the corresponding port and run the tests using:
```
npx playwright test --project=local
```
To run the load tests, run:

NOTE: As load tests use a single account, pay attention that the session per user limit is min the amount of instances you want!
```
npx playwright test --project=scale
```
Set the amount of instances in the ENV file or pass it like this (ex. 100 instances):
```
NUM_INSTANCE=100 npx playwright test --project=scale
```
To run the tests using the Artillery.io framework, run:
```
npx artillery run tests/ide/scalable/artillery/Artillery.ts
```
To run the MCP tests, follow the README in the MCP folder

Project Identifier	Description	Status
local	Runs all functional tests on a local instance, provided by the URL in the env file.
functional	Runs all functional tests on the deployed instance, provided by the URL in the env file.
scale	Runs all scalability tests on the deployed instance, provided by the URL in the env file.
artillery	Runs the scalability test on the deployed instance, using the Artillery.io framework.
artemis	Runs the integration test with Artemis, either local or deployed depending on the URLs set in the env file.
*-setup	These are setup projects and not meant to be run on its own. Dependencies are already set.

Development

Single User Playwright Tests are run using a Test Account for Keycloak, to change the Test User, change the environment variables in GitHub Secrets
-> Settings -> Secrets and variables -> Actions -> Secrets -> Repository Secrets
All functional tests (that can also be run on a local instance) have the following file format:
```
*.functional.spec.ts
```
All scalable tests (that can only be run on a scalable supported instance) have the following file format:
```
*.scale.spec.ts
```
Tests require to have a specific setup files run before them. These are normally already run by requirements of the playwright.config.ts
The tests safe the URL for each instance in a text file under /test-data for debugging and to access them in the tests
Tests are intended to run on the production environment (https://theia.artemis.cit.tum.de)
- As tests include testing of all available programming languages: local images for each language can be found here: https://github.com/orgs/ls1intum/packages?repo_name=artemis-theia-blueprints
