sweet-tooth.endpoint.system — sweet-tooth/endpoint 0.10.10

Introduces some conveniences for dealing with duct systems:

• A multimethod config for naming integrant configs, like :dev, :test, etc.
• An ig/init-key alternative that allows a component's configuration to specify an alternative component implementation, possibly bypassing the ig/init-key implementation entirely
• replacement and shrubbery-mock alternatives

component-spec-with-alternative clj

(component-spec-with-alternative live-spec)

Alternative components are likely run in dev and test environments where components are unlikely to take the same arguments as their live counterparts. This helper function capture that notion for component specs.

config clj multimethod

Provides a way for client application to name different integrant configs, e.g. :test, :dev, :prod, etc

init clj

(init config)

(init config init-keys)

Like integrant.core/init but allows config values specify how to provide an alternative implementation for a component. The alternative will be used instead of whatever would have gotten returned by ig/init-key. This makes it much easier to e.g. mock a component.

init-key clj

(init-key k v)

Allows component configuration to specify alterative component implementations.

init-key-alternative clj multimethod

readers clj

replacement clj

(replacement component)

Retuns a component config that's used to return the given component without initializing the replaced component.

replacement-type clj multimethod

shrubbery-mock clj

(shrubbery-mock)

(shrubbery-mock {:keys [component mock]})

Returns a component configuration that will use init-key-alternative's ::shrubbery-mock implementation. Does not replace the original component's config so that the mocked component can be initialized.

:mock specifies mocked methods and their values. You can use either {:method-name val} or {Protocol {:method-name val}}.

:component defines additional config opts that should get passed to the mocked component. One use for this is to satisfy that component's config spec.

system clj

(system config-name)

(system config-name custom-config)

(system config-name custom-config init-keys)
