Struct httpmock::Then [−][src]
pub struct Then { /* fields omitted */ }
Expand description
A type that allows the specification of HTTP response values.
Implementations
Sets the HTTP response code that will be returned by the mock server.
status
- The status code.
Example:
use httpmock::prelude::*; // Arrange let server = MockServer::start(); let m = server.mock(|when, then|{ when.path("/hello"); then.status(200); }); // Act let response = isahc::get(server.url("/hello")).unwrap(); // Assert m.assert(); assert_eq!(response.status(), 200);
Sets the HTTP response body that will be returned by the mock server.
body
- The response body content.
Example:
use httpmock::prelude::*; use isahc::{prelude::*, ResponseExt}; // Arrange let server = MockServer::start(); let m = server.mock(|when, then| { when.path("/hello"); then.status(200) .body("ohi!"); }); // Act let mut response = isahc::get(server.url("/hello")).unwrap(); // Assert m.assert(); assert_eq!(response.status(), 200); assert_eq!(response.text().unwrap(), "ohi!");
Sets the HTTP response body that will be returned by the mock server.
body
- The response body content.
Example:
use httpmock::prelude::*; use isahc::{prelude::*, ResponseExt}; // Arrange let server = MockServer::start(); let m = server.mock(|when, then|{ when.path("/hello"); then.status(200) .body_from_file("tests/resources/simple_body.txt"); }); // Act let mut response = isahc::get(server.url("/hello")).unwrap(); // Assert m.assert(); assert_eq!(response.status(), 200); assert_eq!(response.text().unwrap(), "ohi!");
Sets the JSON body for the HTTP response that will be returned by the mock server.
The provided JSON object needs to be both, a deserializable and serializable serde object.
Note that this method does not set the “content-type” header automatically, so you need to provide one yourself!
body
- The HTTP response body the mock server will return in the form of a serde_json::Value object.
Example
You can use this method conveniently as follows:
use httpmock::prelude::*; use serde_json::{Value, json}; use isahc::ResponseExt; use isahc::prelude::*; // Arrange let _ = env_logger::try_init(); let server = MockServer::start(); let m = server.mock(|when, then|{ when.path("/user"); then.status(200) .header("content-type", "application/json") .json_body(json!({ "name": "Hans" })); }); // Act let mut response = isahc::get(server.url("/user")).unwrap(); let user: Value = serde_json::from_str(&response.text().unwrap()).expect("cannot deserialize JSON"); // Assert m.assert(); assert_eq!(response.status(), 200); assert_eq!(user.as_object().unwrap().get("name").unwrap(), "Hans");
Sets the JSON body that will be returned by the mock server. This method expects a serializable serde object that will be serialized/deserialized to/from a JSON string.
Note that this method does not set the “content-type” header automatically, so you need to provide one yourself!
body
- The HTTP body object that will be serialized to JSON using serde.
use httpmock::prelude::*; use isahc::{prelude::*, ResponseExt}; // This is a temporary type that we will use for this example #[derive(serde::Serialize, serde::Deserialize)] struct TestUser { name: String, } // Arrange let _ = env_logger::try_init(); let server = MockServer::start(); let m = server.mock(|when, then| { when.path("/user"); then.status(200) .header("content-type", "application/json") .json_body_obj(&TestUser { name: String::from("Hans"), }); }); // Act let mut response = isahc::get(server.url("/user")).unwrap(); let user: TestUser = serde_json::from_str(&response.text().unwrap()).unwrap(); // Assert m.assert(); assert_eq!(response.status(), 200); assert_eq!(user.name, "Hans");
Sets an HTTP header that the mock server will return.
name
- The name of the header.value
- The value of the header.
Example
You can use this method conveniently as follows:
// Arrange use httpmock::prelude::*; use serde_json::Value; use isahc::ResponseExt; let _ = env_logger::try_init(); let server = MockServer::start(); let m = server.mock(|when, then|{ when.path("/"); then.status(200) .header("Expires", "Wed, 21 Oct 2050 07:28:00 GMT"); }); // Act let mut response = isahc::get(server.url("/")).unwrap(); // Assert m.assert(); assert_eq!(response.status(), 200);
Sets a duration that will delay the mock server response.
duration
- The delay.
// Arrange use std::time::{SystemTime, Duration}; use httpmock::prelude::*; let _ = env_logger::try_init(); let start_time = SystemTime::now(); let three_seconds = Duration::from_secs(3); let server = MockServer::start(); let mock = server.mock(|when, then| { when.path("/delay"); then.status(200) .delay(three_seconds); }); // Act let response = isahc::get(server.url("/delay")).unwrap(); // Assert mock.assert(); assert_eq!(start_time.elapsed().unwrap() > three_seconds, true);
