Struct libcnb_test::IntegrationTestContext

pub struct IntegrationTestContext<'a> {
    pub pack_stdout: String,
    pub pack_stderr: String,
    pub image_name: String,
    pub app_dir: PathBuf,
    /* private fields */
}

Context for a currently executing integration test.

Fields

pack_stdout: String

Standard output of pack, interpreted as an UTF-8 string.

pack_stderr: String

Standard error of pack, interpreted as an UTF-8 string.

image_name: String

The name of the image this integration test created.

app_dir: PathBuf

The directory of the app this integration test uses.

This is a copy of the app_dir directory passed to IntegrationTest::new and unique to this integration test run. It is safe to modify the directory contents inside the test.

Implementations

impl<'a> IntegrationTestContext<'a>

pub fn prepare_container(&self) -> PrepareContainerContext<'_>

Prepares a new container with the image from the integration test.

This will not create nor run the container immediately. Use the returned PrepareContainerContext to configure the container, then call start_with_default_process on it to actually create and start the container.

Example:

use libcnb_test::IntegrationTest;

IntegrationTest::new("heroku/buildpacks:20", "test-fixtures/empty-app").run_test(|context| {
    context.prepare_container().start_with_default_process(|container| {
        // ...
    });
});

Trait Implementations

impl<'a> Drop for IntegrationTestContext<'a>

fn drop(&mut self)

Executes the destructor for this type.
