JsonPath JUnit escape character for points

Question

I have a json field called template.welcome.email and I write a unit test that checks to see if this field is present in the response from the server, but I cannot find the escape for the points in the field name. My test code:

@Test public void testEmailTemplates() throws Exception { mockMvc.perform(get("/emailTemplates") .contentType(MediaType.APPLICATION_JSON) .locale(Locale.UK) .accept(MediaType.APPLICATION_JSON)) .andDo(print()) .andExpect(status().isOk()) .andExpect(jsonPath("$.template.welcome.email").exists()) .andExpect(redirectedUrl(null)) .andExpect(forwardedUrl(null)); } 

But I get the following exception because the points are interpreted as paths:

 java.lang.AssertionError: No value for JSON path: $.template.welcome.email, exception: invalid path at org.springframework.test.util.JsonPathExpectationsHelper.evaluateJsonPath(JsonPathExpectationsHelper.java:74) at org.springframework.test.util.JsonPathExpectationsHelper.exists(JsonPathExpectationsHelper.java:121) at org.springframework.test.web.servlet.result.JsonPathResultMatchers$3.match(JsonPathResultMatchers.java:77) at org.springframework.test.web.servlet.MockMvc$1.andExpect(MockMvc.java:141) at 

Do you know any escape character for jsonPath?

Answer 1

As Ida pointed out :

Use parentheses and quotes around your field. For example, if your field is valid.key.with.dot

Refer to it as ['valid.key.with.dot'] and in JsonPath try

JsonPath.read(jsonString, "$.['valid.key.with.dot']")

Use parentheses and quotes around your field. For example, if your field is valid.key.with.dot

Refer to it as ['valid.key.with.dot'] and in JsonPath, try

 JsonPath.read(jsonString, "$.['valid.key.with.dot']")

Answer 3

These days (e.g. io.rest-assured.json-path:3.0.1 ) the notation looks without parentheses:

 // Some Groovy OData V4 $count test // Response looks like: // { "@odata.count": 2, ... } body "'@odata.count'", equalTo(2) 

I found a matching hint in this Git issue .
