## Docs

First, make sure you set up your environment as described above, that will install all the requirements.

### Docs live

During local development, there is a script that builds the site and checks for any changes, live-reloading:

<div class="termy">

```console
$ python ./scripts/docs.py live

<span style="color: green;">[INFO]</span> Serving on http://127.0.0.1:8008

        // Execute
        String result = pingSearchEngineJob.execute();

        // Assert
        assertEquals("test-cluster is alive.", result);
    }

    // Test RED status with state change
    public void test_execute_redStatusNoChange() {
        // Setup mock components

        // Wait for completion with longer timeout
        indexUpdater.join(3000);

        assertFalse(errorOccurred.get());
        // Thread may still be alive in test environment, just check no errors
        // // Thread may still be alive in test environment
        // assertFalse(indexUpdater.isAlive());
    }

                try {
