@Test public void testValidateOnlineRequestPayload() throws Exception { String goodPayload = IOUtils.toString(this.getClass().getResourceAsStream("payload-good.json")); boolean goodResult = this.anomalyDetectionResource.validateOnlineRequestPayload(this.objectMapper.readTree(goodPayload), false); Assert.assertTrue(goodResult); String badPayload = IOUtils.toString(this.getClass().getResourceAsStream("payload-bad.json")); boolean badResult = this.anomalyDetectionResource.validateOnlineRequestPayload(this.objectMapper.readTree(badPayload), false); Assert.assertFalse(badResult); }
