+# Choosing a test runner
+
+A test runner is a program that runs tests.
+
+There are many popular JavaScript test runners, and Vue Test Utils works in all of them. It's test runner agnostic.
+
+However, some popular test runners do not have good support for compiling single file components (SFCs).
+
+## Performance
+
+The fastest test runners are:
+
+- Jest
+- Mocha Webpack
+- tape
+
+You can see a performance comparisson of popular test runners [here](https://github.com/eddyerburgh/vue-unit-test-perf-comparison).
+
+## Features
+
+Jest is the most fully featured test runner. It requires the leat configuration, as it sets up JSDOM by default.
+
+tape is very minimal. If you choose tape, you will need to do a lot of set up yourself.
+
+## Getting started
+
+You can use our guides to get started with a test runner:

+- [Testing SFCs with Jest](testing-SFCs-with-jest.md)
