### Dev config
Create a custom.ini in the conf directory to override default configuration options.
You only need to add the options you want to override. Config files are applied in the order of:
1. grafana.ini
2017-05-21 03:07:21 -05:00
1. custom.ini
2015-03-29 06:30:03 -05:00

In your custom.ini uncomment (remove the leading `;` ) sign. And set `app_mode = development` .

### Running tests
2018-02-09 06:31:37 -06:00
#### Frontend
Execute all frontend tests
```bash
2018-02-09 06:34:10 -06:00
npm run test
2018-02-09 06:31:37 -06:00
```
2017-10-22 00:03:26 -05:00
Writing & watching frontend tests (we have two test runners)
- jest for all new tests that do not require browser context (React+more)
- Start watcher: `npm run jest`
- Jest will run all test files that end with the name ".jest.ts"
- karma + mocha is used for testing angularjs components. We do want to migrate these test to jest over time (if possible).
- Start watcher: `npm run karma`
- Karma+Mocha runs all files that end with the name "_specs.ts".
2018-02-09 06:31:37 -06:00
