Clojure: Expectations Ignore A Variable Number Of Args In An Interaction Test

March 20, 2013

Over the past year I've written the same test a few times.

This test accomplishes what I'm looking for when I write it - verification that my-fn isn't called. However, it doesn't prevent me from future regressions where my-fn is called with 0, 2, or 2+ arguments. After being bitten by this issue a few times I decided to add an argument matching function that will accept any value for the argument at it's index, and any value for all of the arguments at a greater index. This argument matching function is anything&

The following example is similar to what's above, except any call to my-fn will result in a failure

My original intent was to protect against the scenario I described above*; however, what I ended up with is actually flexible enough to allow me to test other situations as well. For example, I've often found myself testing that a log message was written at a certain level, but not being interested in testing the actual message. The logging I'm working with allows a variable number of arguments, so anything& is perfect for verifying that no matter what args are passed in, the tests passes as long as the level is set correctly.

The anything& matching function gives me an extra bit of flexibility that can come in handy at times.

Smarter duplication detection!

October 18, 2017

Our duplication analysis is great for finding accidental copy-paste or slightly modified pieces of code in your project. However, sometimes it would report common pieces of boilerplate when those are perfectly legitimate uses of the language. One example is large numbers of module requires in JavaScript, such as:

const ModuleA = require("module_a"),
  ModuleB = require("module_b"),
  ModuleC = require("module_c"),
  ModuleD = require("module_d"),
  ModuleE = require("module_e");

Another example is import statements:

import React, { Component, PropTypes } from 'react'
import { Table, TableBody, TableHeader, TableHeaderColumn, TableRow } from 'material-ui/Table'
import values from 'lodash/values'
import { v4 } from 'uuid

We’ve recently made our duplication analysis smarter so that common patterns like these in Java, JavaScript, and PHP will no longer be reported as duplication on Code Climate, so you can be more confident in the duplication results you do see from Code Climate.
