path: &'_ str
) -> Result<String, GooseTaskError>
A helper that prepends a base_url to all relative paths.
A base_url is determined per user thread, using the following order of precedence:
--host
(host specified on the command line when running load test)GooseTaskSet.host
(default host defined for the current task set)GooseAttack.host
(default host defined for the current load test)

) -> Result<GooseResponse, GooseTaskError>
A helper to make a GET
request of a path and collect relevant statistics.
Automatically prepends the correct host.
(If you need to set headers, change timeouts, or otherwise make use of the
reqwest::RequestBuilder

) -> Result<GooseResponse, GooseTaskError>
Builds the provided
reqwest::RequestBuilder
object and then executes the response. If statistics are being displayed, it
also captures request statistics.
It is possible to build and execute a RequestBuilder
object directly with
Reqwest without using this helper function, but then Goose is unable to capture
statistics.
Calls to user.goose_send()
returns a Result
containing a GooseResponse
on success,
and a tokio::sync::mpsc::error::SendError<bool>
on failure. Failure only happens when
--throttle-requests
is enabled and the load test completes. The GooseResponse
object
(goose.request
), and the
Reqwest response (goose.response
).
Example
use goose::prelude::*; let mut task = task!(get_function); /// A simple task that makes a GET request, exposing the Reqwest /// request builder. async fn get_function(user: &GooseUser) -> GooseTaskResult { let request_builder = user.goose_get("/path/to/foo").await?; let goose = user.goose_send(request_builder, None).await?; // Do stuff with goose.request and/or goose.response here. Ok(()) }
pub fn set_success(&self, request: &mut GooseRawRequest) -> GooseTaskResult
[src]
Manually mark a request as a success.
By default, Goose will consider any response with a 2xx status code as a success. It may be valid in your test for a non-2xx HTTP status code to be returned. A copy of your original request is returned with the response, and a mutable copy must be included when setting a request as a success.
Example
use goose::prelude::*; let mut task = task!(get_function); /// A simple task that makes a GET request. async fn get_function(user: &GooseUser) -> GooseTaskResult { let mut goose = user.get("/404").await?; if let Ok(response) = &goose.response { // We expect a 404 here. if response.status() == 404 { return user.set_success(&mut goose.request); } } Err(GooseTaskError::RequestFailed { raw_request: goose.request.clone(), }) }
pub fn set_failure(
&self,
tag: &str,
request: &mut GooseRawRequest,
headers: Option<&HeaderMap>,
body: Option<&str>
) -> GooseTaskResult
[src]
&self,
tag: &str,
request: &mut GooseRawRequest,
headers: Option<&HeaderMap>,
body: Option<&str>
) -> GooseTaskResult
Manually mark a request as a failure.
By default, Goose will consider any response with a 2xx status code as a success. You may require more advanced logic, in which a 2xx status code is actually a failure. A copy of your original request is returned with the response, and a mutable copy must be included when setting a request as a failure.
Calls to set_failure
must include four parameters. The first, tag
, is an
arbitrary string identifying the reason for the failure, used when logging. The
second, request
, is a mutable reference to the GooseRawRequest
object of the
request being identified as a failure (the contained success
field will be set
to false
, and the update
field will be set to true
). The last two
parameters, header
and body
, are optional and used to provide more detail in
logs.
This also calls
log_debug
.
Example
use goose::prelude::*; let mut task = task!(loadtest_index_page); async fn loadtest_index_page(user: &GooseUser) -> GooseTaskResult { let mut goose = user.get_named("/", "index").await?; if let Ok(response) = goose.response { // We only need to check pages that returned a success status code. if response.status().is_success() { match response.text().await { Ok(text) => { // If the expected string doesn't exist, this page load // was a failure. if !text.contains("this string must exist") { // As this is a named request, pass in the name not the URL return user.set_failure("string missing", &mut goose.request, None, None); } } // Empty page, this is a failure. Err(_) => { return user.set_failure("empty page", &mut goose.request, None, None); } } } }; Ok(()) }
pub fn log_debug(
&self,
tag: &str,
request: Option<&GooseRawRequest>,
headers: Option<&HeaderMap>,
body: Option<&str>
) -> GooseTaskResult
[src]
&self,
tag: &str,
request: Option<&GooseRawRequest>,
headers: Option<&HeaderMap>,
body: Option<&str>
) -> GooseTaskResult
Write to debug_log_file if enabled.
This function provides a mechanism for optional debug logging when a load test is running. This can be especially helpful when writing a load test. Each entry must include a tag, which is an arbitrary string identifying the debug message. It may also optionally include references to the GooseRawRequest made, the headers returned by the server, and the text returned by the server,
Calls to
set_failure
To enable the debug log, a load test must be run with the --debug-log-file=foo
option set, where foo
is either a relative or an absolute path of the log file
to create. Any existing file will be overwritten.
In the following example, we are logging debug messages whenever there are errors.
Example
use goose::prelude::*; let mut task = task!(loadtest_index_page); async fn loadtest_index_page(user: &GooseUser) -> GooseTaskResult { let mut goose = user.get("/").await?; match goose.response { Ok(response) => { // Grab a copy of the headers so we can include them when logging errors. let headers = &response.headers().clone(); // We only need to check pages that returned a success status code. if !response.status().is_success() { match response.text().await { Ok(html) => { // Server returned an error code, log everything. user.log_debug( "error loading /", Some(&goose.request), Some(headers), Some(&html), ); }, Err(e) => { // No body was returned, log everything else. user.log_debug( &format!("error loading /: {}", e), Some(&goose.request), Some(headers), None, ); } } } }, // No response from server. Err(e) => { user.log_debug( "no response from server when loading /", Some(&goose.request), None, None, ); } } Ok(()) }
pub async fn set_client_builder<'_>(
&'_ self,
builder: ClientBuilder
) -> Result<(), GooseTaskError>
[src]
&'_ self,
builder: ClientBuilder
) -> Result<(), GooseTaskError>
Manually build a Reqwest client.
By default, Goose configures two options when building a Reqwest client. The first
configures Goose to report itself as the user agent requesting web pages (ie
goose/0.9.0
). The second option configures Reqwest to store cookies, which is
generally necessary if you aim to simulate logged in users.
Default configuration:
use reqwest::Client; static APP_USER_AGENT: &str = concat!(env!("CARGO_PKG_NAME"), "/", env!("CARGO_PKG_VERSION")); let builder = Client::builder() .user_agent(APP_USER_AGENT) .cookie_store(true);
Alternatively, you can use this function to manually build a Reqwest client with custom
configuration. Available options are found in the
Reqwest ClientBuilder
documentation.
When manually building a Reqwest client, there are a few things to be aware of:
- Manually building a client in
test_start
will only affect requests made during test setup; - Manually building a client in
test_stop
will only affect requests made during test teardown; - A manually built client is specific to a single Goose thread -- if you are
generating a large load test with many users, each will need to manually build their
own client (typically you'd do this in a Task that is registered with
set_on_start()
in each Task Set requiring a custom client; - Manually building a client will completely replace the automatically built client with a brand new one, so any configuration, cookies or headers set in the previously built client will be gone;
- You must include all desired configuration, as you are completely replacing Goose
defaults. For example, if you want Goose clients to store cookies, you will have to
include
.cookie_store(true)
.
In the following example, the Goose client is configured with a different user agent, sets a default header on every request, and stores cookies.
Example
use goose::prelude::*; task!(setup_custom_client).set_on_start(); async fn setup_custom_client(user: &GooseUser) -> GooseTaskResult { use reqwest::{Client, header}; // Build a custom HeaderMap to include with all requests made by this client. let mut headers = header::HeaderMap::new(); headers.insert("X-Custom-Header", header::HeaderValue::from_str("custom value").unwrap()); let builder = Client::builder() .default_headers(headers) .user_agent("custom user agent") .cookie_store(true); user.set_client_builder(builder).await?; Ok(()) }
pub async fn set_base_url<'_, '_>(
&'_ self,
host: &'_ str
) -> Result<(), GooseTaskError>
[src]
&'_ self,
host: &'_ str
) -> Result<(), GooseTaskError>
Some websites use multiple domains to serve traffic, redirecting depending on the user's roll. For this reason, Goose needs to respect a redirect of the base_url and subsequent paths should be built from the redirect domain.
For example, if the base_url (ie --host) is set to foo.example.com and the load test requests /login, thereby loading http://foo.example.com/login and this request gets redirected by the server to http://foo-secure.example.com/, subsequent requests made by this user need to be against the new foo-secure.example.com domain. (Further, if the base_url is again redirected, such as when loading http://foo-secure.example.com/logout, the user should again follow for subsequent requests, perhaps in this case back to foo.example.com.)
Load tests can also request absolute URLs, and if these URLs are redirected it does not affect the base_url of the load test. For example, if foo.example.com is the base url, and the load test requests http://bar.example.com (a different domain) and this request gets redirected to http://other.example.com, subsequent relative requests would still be made against foo.example.com.
This functionality is used internally by Goose to follow redirects of the base_url, but it is also available to be manually invoked from a load test such as in the following example.
Example
use goose::prelude::*; fn main() -> Result<(), GooseError> { GooseAttack::initialize()? .register_taskset(taskset!("LoadtestTasks").set_host("http//foo.example.com/") .set_wait_time(0, 3)? .register_task(task!(task_foo).set_weight(10)?) .register_task(task!(task_bar)) ) .execute()?; Ok(()) } async fn task_foo(user: &GooseUser) -> GooseTaskResult { let _goose = user.get("/").await?; Ok(()) } async fn task_bar(user: &GooseUser) -> GooseTaskResult { // Before this task runs, all requests are being made against // http://foo.example.com, after this task runs all subsequent // requests are made against http://bar.example.com/. user.set_base_url("http://bar.example.com/"); let _goose = user.get("/").await?; Ok(()) }
