I&amp;#x27;ve written more about that here: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;lwn.net&amp;#x2F;Articles&amp;#x2F;821358&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;lwn.net&amp;#x2F;Articles&amp;#x2F;821358&amp;#x2F;&lt;/a&gt;&lt;p&gt;Personally I find the &amp;quot;cutesy&amp;quot; names like Expect(a).To.Equal(b) and It(&amp;quot;should ...&amp;quot;) patronizing and too English-like (code is not a human language). Similarly, I wouldn&amp;#x27;t like a language that made you write:&lt;p&gt;&lt;pre&gt;&lt;code&gt;   Please.Print(1.Plus.2)
   Log.To(Console).Text(&amp;quot;did something&amp;quot;)
&lt;/code&gt;&lt;/pre&gt;
The vanilla Go approach can get a bit verbose when you&amp;#x27;re doing lots of asserts. In that case, you can use standard language features like refactoring things to variables or helper functions, or table-driven tests.&lt;p&gt;But if you really want assert-style code, I like the &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;labix.org&amp;#x2F;gocheck&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;labix.org&amp;#x2F;gocheck&lt;/a&gt; approach:&lt;p&gt;&lt;pre&gt;&lt;code&gt;   c.Assert(a, Equals, b)
&lt;/code&gt;&lt;/pre&gt;
Because there&amp;#x27;s only one function (Assert) and a bunch of comparator names to learn.</text><parent_chain><item><author>latch</author><text>I never understood their reason for the verbose and unfriendly ergonomics:&lt;p&gt;if a != b {

This is especially problematic with table-based tests or tests with large numbers of assertions where the closest human-readable label might have been described too generically.&lt;p&gt;I much prefer to be able write out &amp;quot;foo broke in such such way: expected %s, got %s&amp;quot; than have the team rely on a machine attempting to generate a description and getting a bad description because the human is encouraged to be too lazy to write a proper description and the test framework is not smart enough to write a proper one for them.</text><parent_chain><item><author>latch</author><text>I never understood their reason for the verbose and unfriendly ergonomics:&lt;p&gt;if a != b {
