Struct MockDockerfileEnvironment 

pub struct MockDockerfileEnvironment {
    pub dockerfiles: BTreeMap<String, String>,
    pub build_args: BTreeMap<String, String>,
}

In-memory mock environment for tests. Pre-load Dockerfile text by path + build-arg values by name.

Fields

dockerfiles: BTreeMap<String, String>

build_args: BTreeMap<String, String>

Implementations

impl MockDockerfileEnvironment

pub fn with_dockerfile(self, path: &str, text: &str) -> Self

pub fn with_build_arg(self, name: &str, value: &str) -> Self

Trait Implementations

impl Default for MockDockerfileEnvironment

fn default() -> MockDockerfileEnvironment

Returns the “default value” for a type.

impl DockerfileEnvironment for MockDockerfileEnvironment

fn read_dockerfile(&self, path: &str) -> Result<String, String>

Read the Dockerfile at path. In the canonical-instance path the “path” is just the spec’s name and the text comes from the authored spec itself; a real consumer wraps std::fs::read_to_string.

fn resolve_build_arg(&self, name: &str) -> Option<String>

Resolve a build-arg’s value from the environment (e.g. --build-arg TARGETARCH=amd64). Returns None on miss — the interpreter falls back to the ARG’s declared default, or leaves it unresolved if neither exists.
