## Testing Challenges
Before you [create a pull request](how-to-open-a-pull-request.md) for your changes, you need to validate that the changes you have made do not inadvertently cause problems with the challenge. To test all challenges run `npm run test:curriculum`. To save time you can limit the tests to one challenge by performing the following steps:
1. In the `.env` file, set the environment variable `TEST_CHALLENGES_FOR_LANGS` to the language of the challenge(s) you need to test. The currently accepted values are `english`, `arabic`, `chinese`, `portuguese`, `russian` and `spanish`.
2. Switch to the `curriculum` directory:
```
cd curriculum
```
3. Run the following for each challenge file for which you have changed any `testString`s or added solutions:
```
npm run test -- -g 'the full English title of the challenge'
```
Once you have verified that each challenge you've worked on passes the tests, please create a pull request.
