+Some queries variants that Testing Library provides are

+errors in the tests. The promise will be considered as handled when:
+
+- using the `await` operator
+- chaining the `then` method
+- chaining `resolves` or `rejects` from jest
+- it's returned from a function (in this case, that particular function will be analyzed by this rule too)
 
 Examples of **incorrect** code for this rule:
 
 ```js
-const foo = () => {
-  // ...
-  const rows = findAllByRole('row');
-  // ...
-};
-
-const bar = () => {
-  // ...
-  findByText('submit');
-  // ...
-};
-
-const baz = () => {
-  // ...
-  screen.findAllByPlaceholderText('name');
-  // ...
-};
+// async query without handling promise
+const rows = findAllByRole('row');
+
+findByIcon('search');
+
+screen.findAllByPlaceholderText('name');
+```
+
+```js
+// promise from async query returned within wrapper function without being handled
+const findMyButton = () => findByText('my button');
+
+const someButton = findMyButton(); // promise unhandled here
 ```
 
 Examples of **correct** code for this rule:
 
 ```js
 // `await` operator is correct
-const foo = async () => {
-  // ...
-  const rows = await findAllByRole('row');
-  // ...
-};
+const rows = await findAllByRole('row');
+
+await screen.findAllByPlaceholderText('name');
+
+const promise = findByIcon('search');
+const element = await promise;
+```
 
+```js
 // `then` method is correct
-const bar = () => {
-  // ...
-  findByText('submit').then(() => {
-    // ...
-  });
-};
-
-const baz = () => {
-  // ...
-  await screen.findAllByPlaceholderText('name');
-  // ...
-};
+findByText('submit').then(() => {});
 
+const promise = findByRole('button');
+promise.then(() => {});
+```
+
+```js
 // return the promise within a function is correct too!
 const findMyButton = () => findByText('my button');
+```
+
+```js
+// promise from async query returned within wrapper function being handled
+const findMyButton = () => findByText('my button');
 
+const someButton = await findMyButton();
+```
+
+```js
 // using a resolves/rejects matcher is also correct
 expect(findByTestId('alert')).resolves.toBe('Success');
 expect(findByTestId('alert')).rejects.toBe('Error');
 ```
 
+```js
+// sync queries don't need to handle any promise
+const element = getByRole('role');
+```
