For a simple example of the testing process, check out the [[Test_a_function#Go]] task.
=={{Header|Insitux}}==
Alongside assertions and mocking available in pure Insitux (see [https://www.rosettacode.org/wiki/Test_a_function#Insitux Test a function]), the Node.js REPL has the ability to generate a code coverage report of unvisited lines and columns, useful for writing thorough unit tests. Here is a basic demonstration:
<syntaxhighlight lang="insitux" line>
(function subject x y z
(return-unless (num? x) x)
(return-unless (num? y) y)
(if x y z))
(assert (= (subject :a 2 3) :a))
(assert (= (subject 1 :b 3) :b))
(assert (= (subject 1 2 3) 2))
</syntaxhighlight>
{{out}}
Invoked from the terminal with <code>npx ix . -unv</code>.
<pre>
unvisited.txt generated: 1 unvisited (97% coverage)
true
</pre>
<code>unvisited.txt</code>:
<pre>
entry.ix 4 11
</pre>
We're being told here that line 4, column 11 has an expression which was not visited at runtime. Through investigation we see that it's impossible for <code>z</code> to be returned, as <code>x</code> must always be a number - an inherently truthy value.

Line 257 ⟶ 298:
As a language chiefly intended for embedding, Wren's standard library is quite small and there is no built-in support for unit testing as such.
However, there is an external module called [[
