-        When the <kbd>zig test</kbd> tool is building a test runner, only resolved {#syntax#}test{#endsyntax#}
-        declarations are included in the build. Initially, only the given Zig source file's top-level
-        declarations are resolved. Unless nested {#link|containers|Containers#} are referenced from a top-level test declaration,
-        nested container tests will not be resolved.

-        The code sample below uses the {#syntax#}std.testing.refAllDecls(@This()){#endsyntax#} function call to
-        reference all of the containers that are in the file including the imported Zig source file. The code
-        sample also shows an alternative way to reference containers using the {#syntax#}_ = C;{#endsyntax#}
-        syntax. This syntax tells the compiler to ignore the result of the expression on the right side of the
-        assignment operator.
