    SuperTest

    SuperTest

    Super-agent driven library for testing node.js HTTP servers

    ...You may pass an http.Server, or a Function to request(), if the server is not already listening for connections then it is bound to an ephemeral port for you so there is no need to keep track of ports. One thing to note, is that superagent now sends any HTTP error (anything other than a 2XX response code) to the callback as the first argument if you do not add a status code expect (i.e. .expect(302)). Expectations are run in the order of definition. This characteristic can be used to modify the response body or headers before executing an assertion.

    ...In eslint-plugin-jsdoc, a few options, such as, exemptedBy and contexts, may be used across different rules. eslint-plugin-jsdoc options, if present, are generally in the form of an object supplied as the second argument in an array after the error level (any exceptions to this format are explained within that rule's docs). One can use minLines and maxLines to indicate how many line breaks (if any) will be checked to find a jsdoc comment block before the given code block. These settings default to 0 and 1 respectively. In conjunction with the require-jsdoc rule, these settings can be enforced so as to report problems if a jsdoc block is not found within the specified boundaries. ...
