    <p>WireMock is a simulator for HTTP-based APIs. Some might consider it a <strong>service virtualization</strong> tool or a <strong>mock server</strong>.<br><br>
      It enables you to <strong>stay productive</strong> when an API you depend on <strong>doesn't exist</strong> or isn't complete.
      It supports testing of <strong>edge cases and failure modes</strong> that the real API won't reliably produce.
      And because it's fast it can <strong>reduce your build time</strong> from hours down to minutes.<p>
