## Indigo Service

Ketcher uses Indigo Service for server operations.
You can use `--api-path` parameter to start with it:

    npm start -- --api-path=<server-url>
For production build:

    npm run build -- --api-path=<server-url>

You can find the instruction for service installation
[here](http://lifescience.opensource.epam.com/indigo/service/index.html).

## Tests instructions

You can start tests for input/output `.mol`-files and render.

    npm test

Tests are started for all structures in `test/fixtures` directory.

To start the tests separately:

    npm run test-io
    npm run test-render

#### Parameters

You can use following parameters to start the tests:
 - `--fixtures` - for the choice of a specific directory with molecules
 - `--headless` - for start of the browser in headless mode

```
npm run test-render -- --fixtures=fixtures/super --headless
```

If you have added new structures for testing to the `test/fixtures` directory 
you have to generate `svg` from them for correct render-test with:

    npm run generate-svg
