Struct goose::GooseAttack

pub struct GooseAttack { /* fields omitted */ }

Internal global state for load test.

Implementations

impl GooseAttack

Goose's internal global state.

pub fn initialize() -> Result<GooseAttack, GooseError>

Load configuration from command line and initialize a GooseAttack.

Example

    use goose::prelude::*;

    let mut goose_attack = GooseAttack::initialize();

pub fn initialize_with_config(
    configuration: GooseConfiguration
) -> Result<GooseAttack, GooseError>

Initialize a GooseAttack with an already loaded configuration. This should only be called by worker instances.

Example

    use goose::{GooseAttack, GooseConfiguration};
    use gumdrop::Options;

    let configuration = GooseConfiguration::parse_args_default_or_exit();
    let mut goose_attack = GooseAttack::initialize_with_config(configuration);

pub fn initialize_logger(&self)

pub fn register_taskset(self, taskset: GooseTaskSet) -> Self

A load test must contain one or more GooseTaskSets. Each task set must be registered into Goose's global state with this method for it to run.

Example

    use goose::prelude::*;

fn main() -> Result<(), GooseError> {
    GooseAttack::initialize()?
        .register_taskset(taskset!("ExampleTasks")
            .register_task(task!(example_task))
        )
        .register_taskset(taskset!("OtherTasks")
            .register_task(task!(other_task))
        );

    Ok(())
}

async fn example_task(user: &GooseUser) -> GooseTaskResult {
    let _goose = user.get("/foo").await?;

    Ok(())
}

async fn other_task(user: &GooseUser) -> GooseTaskResult {
    let _goose = user.get("/bar").await?;

    Ok(())
}

pub fn test_start(self, task: GooseTask) -> Self

Optionally define a task to run before users are started and all task sets start running. This is would generally be used to set up anything required for the load test.

When running in a distributed Gaggle, this task is only run one time by the Manager.

Example

    use goose::prelude::*;

fn main() -> Result<(), GooseError> {
    GooseAttack::initialize()?
        .test_start(task!(setup));

    Ok(())
}

async fn setup(user: &GooseUser) -> GooseTaskResult {
    // do stuff to set up load test ...

    Ok(())
}

pub fn test_stop(self, task: GooseTask) -> Self

Optionally define a task to run after all users have finished running all defined task sets. This would generally be used to clean up anything that was specifically set up for the load test.

When running in a distributed Gaggle, this task is only run one time by the Manager.

Example

    use goose::prelude::*;

fn main() -> Result<(), GooseError> {
    GooseAttack::initialize()?
        .test_stop(task!(teardown));

    Ok(())
}

async fn teardown(user: &GooseUser) -> GooseTaskResult {
    // do stuff to tear down the load test ...

    Ok(())
}

pub fn execute(self) -> Result<GooseMetrics, GooseError>

Execute the load test.

Example

use goose::prelude::*;

fn main() -> Result<(), GooseError> {
    let _goose_metrics = GooseAttack::initialize()?
        .register_taskset(taskset!("ExampleTasks")
            .register_task(task!(example_task).set_weight(2)?)
            .register_task(task!(another_example_task).set_weight(3)?)
        )
        .execute()?;

    Ok(())
}

async fn example_task(user: &GooseUser) -> GooseTaskResult {
    let _goose = user.get("/foo").await?;

    Ok(())
}

async fn another_example_task(user: &GooseUser) -> GooseTaskResult {
    let _goose = user.get("/bar").await?;

    Ok(())
}
