 Create a test file in this directory with the name `*.js`.
 
+> [!TIP]
+> Writing great tests is hard.
+> 
+> You can make our live much simpler by following this guidance:
+> - Use `describe()` to group related tests
+> - Use `test()` for individual test cases
+> - One test per scenario
+> - Use descriptive test names: `function() [behavior] [condition]`
+> - Don't prefix with "Test" or "Should"
+
 ## Template
 
 ```js
-const test = require("node:test");
+const { describe, test } = require("node:test");
 const assert = require("node:assert");
 
-test("Test name", async (t) => {
-    assert.strictEqual(1, 1);
+describe("Feature Name", () => {
+    test("function() returns expected value when condition is met", () => {
+        assert.strictEqual(1, 1);
+    });
 });
 ```
