+title: Using Fake Timers
+sidebar_label: Using Fake Timers
+---
+
+In some cases, when your code uses timers (`setTimeout`, `setInterval`,
+`clearTimeout`, `clearInterval`), your tests may become unpredictable, slow and
+flaky.
+
+To solve these problems, or if you need to rely on specific timestamps in your
+code, most testing frameworks offer the option to replace the real timers in
+your tests with fake ones. This should be used sporadically and not on a regular
+basis since using it contains some overhead.
+
+When using fake timers in your tests, all of the code inside your test uses fake
+timers.  
+The common pattern to setup fake timers is usually within the `beforeEach`, for
+example:
+
+```js
+// Fake timers using Jest
+beforeEach(() => {
+  jest.useFakeTimers()
+})
+```
+
+When using fake timers, you need to remember to restore the timers after your
+test runs.  
+The main reason to do that is to prevent 3rd party libraries running after your
+test finishes (e.g cleanup functions), from being coupled to your fake timers
+and use real timers instead.  
+For that you usually call `useRealTimers` in `afterEach`.  
+It's important to also call `runOnlyPendingTimers` before switching to real
+timers.  
+This will ensure you flush all the pending timers before you switch to real
+timers. If you don't progress the timers and just switch to real timers, the
+scheduled tasks won't get executed and you'll get an unexpected behavior.  
+This is mostly important for 3rd parties that schedule tasks without you being
+aware of it.  
+Here's an example of doing that using jest:
+
+```js
+// Running all pending timers and switching to real timers using Jest
+afterEach(() => {
+  jest.runOnlyPendingTimers()
+  jest.useRealTimers()
+})
+```
