Wiremock error: Request was not matched as there were no stubs registered

Question

@ClassRule
    public static WireMockRule wireMockRule = new WireMockRule(9898);

    @Test
    public void createXmlFile() {
        stubFor(get(urlPathEqualTo("/data/racing/"))
                .willReturn(aResponse()
                        .withBody(loadJSONFile("unibet-demo-input.json"))));

    }

I don't know what is going wrong here!

Solution

I had to add wireMockRule on stubFor to make it work.

@ClassRule
public static WireMockRule wireMockRule = new WireMockRule(9898);

@Test
public void createXmlFile() {
    wireMockRule.stubFor(get(urlPathEqualTo("/data/racing/"))
        .willReturn(aResponse()
            .withBody(loadJSONFile("unibet-demo-input.json"))));
}
