# Implementation of scenario steps

## Server aliases

    IMPLEMENTS GIVEN server is also known as (\S+)
    import yarnhelper
    h = yarnhelper.YarnHelper()
    h.set_variable('SERVER', h.get_next_match())

## HTTP requests

    IMPLEMENTS WHEN user fetches (\S+)
    import yarnhelper
    h = yarnhelper.YarnHelper()
    server = h.get_variable('SERVER')
    url = h.get_next_match()
    status, body = h.http_get(server, url)
    h.set_variable('http_status', status)
    h.set_variable('http_body', body)

    IMPLEMENTS THEN HTTP status is (\d+)
    import yarnhelper
    h = yarnhelper.YarnHelper()
    expected = h.get_variable('http_status')
    actual = int(h.get_next_match())
    h.assertEqual(expected, actual)

    IMPLEMENTS THEN HTTP body matches "(.*)"
    import re, yarnhelper
    h = yarnhelper.YarnHelper()
    body = h.get_variable('http_body')
    pattern = h.get_next_match()
    m = re.search(pattern, body)
    h.assertNotEqual(m, None)
